I am looking for opinions on Deutz engines. Specifically for irrigation. I grow rice and run 10-12 power units an average of 750 - hrs. per yr. I have heard of savings in the 1 to 1.5 gallon an hour range. Running this many hours with high diesel costs would be a big savings if true. I now primarily run Deere engines due to parts and service availability. Many of my older Deere units have high hours and will need replacing in the next couple of years. Dont think fuel prices are coming down any time soon so I need more efficent engines. So, fire away on price, longevity, overhaul cost or anything else you can think of about these engines. Any help is greatly appreciated. This board is a great resource, where else can you pick the brains of this many people for unbiased advice.

Mount Vernon, WALet me start by saying that I am not speaking from experience here, only speculating based on what I think is true. I can't imagine an air-cooled Deutz (assuming you're looking at an air cooled model ) being more efficient than a water cooled model for pumping irrigation. An air cooled model still has to turn a fan. A water cooled model does not. Figuring a fan at full tilt consumes about 5% or so of an engine's HP, this has to add up over the long haul.
Some will say that a water cooled model still has to turn a water pump. Maybe so, but that amount is minimal compared to the HP required to drive a fan.We've got three of them. I'm not an expert, but you know everyone has an opinion as well as certain other parts of their body.
I can't speak about fuel comparisons, but I can tell you we've got a 6 cylinder running a 125kw that uses 4gallon per hour, pumping gpm with 2 submersible pumps and a 7 tower corner. The other two are on small systems, both of them are 4 cylinder motors on 40 kw generators, one pumps 650 gpm the other pumps 475. The first one is running a solid 2 gph, the second about 1.75 gph. Both of them are driving submersible pumps and electric pivots.
We've never had anything else to compare them to so I don't know if that is good or bad. One of the little ones will probably break 10,000 hours this summer, the other one is in the hour range. I can't remember for sure, but I think the 6 cylinder is around hours.
The only thing we did to them was get them into the dealer and let them run the overhead and check timing etc on them. Nothing major, they looked at the generators while they were there, all 3 are Lima's. We put a new carrier bearing in the end while we had them there. If memory serves me we spent about $ total for the 3 of them. We had a couple of fan bearings go out while we were running so we changed the third one out also. Not a huge item. I think we're on our third set of belts on them.
We change the oil once a week when we are running 24/7, change the air cleaner oil at the start of each season. The 6 cyl also has a bypass filter on the oil. Seems like they get a little grimier (I know that's not a real word ) than our tractor motors do and every couple years we hire a mobile wash to come wash off the oil etc. that has stuck to them. Gunk tends to accumulate around the cooling fins even if you are careful. They only charge us $100 and do a great job. It would be a real hassle for us to get a high pressure washer to them because we'd have to take a generator to run it and a tank for water.
You have to watch where the crank case breather vents out because they tend to want to suck it back in the cooling fan, but that may be a problem with other brands also sucking through the radiator.
Our number one complaint about them is mice tend to get into all the air cooling fins. If we are there when they shut down you can open up the side panel which helps, but if they shut down with the pivot sis then the panel is closed and warm and in 24 h ours they have a nest in them. They are a real pain to get out you really need to have an air compressor and blow out all the fins to make sure you don't have one blocked and scorch a cylinder wall.
Second complaint is there is no way to drain the oil filter before you take it off, no matter what you do it is going to make a mess and run all over the side of the motor or you will use up a roll of towels trying to keep it from it. We've even tried to poke a hole and let it drain out, no matter what you do there is another shot of oil that drains out of the overhead lines after you crack it from the base.
We went with Deutz because that is what our irrigation equp. dealer was selling and using. We had heard really good things about Lima generators and felt we'd rather get what we thought was a good generator and deal with a motor that was unknown to us. Our service comes out of Diesel Power in Omaha and for what little we've needed so far they have been ok to work with.
If I was doing it again I think I would worry less about the generator and stick to something that I can get local service on. All things being equal I'd probably go with the Deere or if you had good service from Cat or Cummins I would not be scared of either of them. A dealer who had rental units in stock would mean more to me than the actual brand if it was any of the 3 I mentioned.
I hope this helps, remember it's worth exactly what you paid for it : )

WyomingBern, remember when we pushed a pencil around on irrigation engines for this outfit?

I seem to recall it was a six-cylinder Deutz, liquid-cooled, with a heat exchanger to use the irrigation water for cooling that came out best in efficiency, followed by the NH Genesis engine. We reckoned the best thing to do was ditch the cooling fan and cool the engine coolant with the heat exchanger. I seem to recall that we found efficiencies (on paper ) up in the 24 HP-hr/gal range.
From owning two Deutz air-cooled engines in Hesston balers, I can say that they are reliable, very well made engines that always start without a block heater or ether. If one does go with air-cooled Deutz engines, it is vital to keep the cooling fins clean. Other than that, I have absolutely no complaints about them. Easy to start, easy to service, very little maintenance required. I wish everything were as nice as the Deutz engines.
McLeod County MinnesotaOne of my combines has an air cooled Deutz V8 that I really like. It is quiet, reliable, fuel efficient and runs very smoothly. It is the only diesel engine we have that will idle below 300 rpms which isn’t very important but it does show how smoothly it runs. The combine is only 16 years old so I have no experience with major engine repairs.
I would disagree with Bern’s comment, “An air cooled model still has to turn a fan. A water cooled model does not.” I don’t have irrigation engines which may be a different breed of cat, but all of my tractor, truck, and combine engines have fans regardless of whether they use water as a heat transfer medium.
West TexasDeutz at one time had the most fuel efficient diesel engines in the world. I don't know if they still do but having run Deutz tractors and tractors with Deutz engines along side with other brands of same hp doing same work the Deutz engines would do almost twice as much work on the same amount of fuel.
At that time they were very fuel efficient, quiet and strong.
All of these were air cooled non turbo 6 cylinder engines.
Huntley MontanaFor Irrigation work they are the ENGINE. # 2 would be a HATZ.
Like the others said keep the fins clean. You can have all the rest as far as I'm concerned. Will burn a LOT less Diesel than anything else I've seen. With $2-3 Diesel , the 1-4 gallon per Hr less will pay for any problems 2-10x over.You asked-I answer. I run three of them. Make sure the fuel injection pump has a live oil line running to it. make sure the fan bearings dont even have remote roughness, at the speed they run any drag is TOO much. There is an idler on the front belt which gradualy wears crooked. When you over haul them, you will pay to have all the head bolts drilled out because they are all so rusted and mouse pee'd tight. And the bill to drill them will knock you for a 'loop'. Mice will crawl inside the air chamber and also the air cleaner and make nests every time the motor is "OFF". Saw a guy tie window screen around air intake. Helped that. Air flow fins get blowed out real quick if you start the motor with the cover off and take a wire to get going to pry loose and grind the mice (if your lucky ). I am going to try mouse poison when off and see if I can taget those pregnant mothers. Keep a supply of belts in one hand when runnuing season. They eat belts 'really' fast. The stock generators are junk. Aftermarket alternators dont last from noon to dinner. A alternator running off the driveshaft would last alot longer. Or one of those solar chargers for the little battery drain the murphy draws would be an improvement.
Overall, I "think" they make a more efficent motor these days.. motor salesman said a few years ago that an Izuzu was the hot seller, somebody may have surpassed that by now. One of those efficency exams might be in order to make sure things are up to snuff. I cant imagine that anything will fix the high pumping costs of high diesel. If you have a 24/7 motor figure out what that fuel is costing, per hour, per day, per week, per month, per season, then figure out if your total crop is 'worth' that much??? Now where is the 'other' costs going to come from???Congradulations, you now own the best part of $4. corn you might get sold in harvest season, for $1.50-1.75 IF your lucky when your bins at home get full too quick.Defintely looking at the air cooled ones. Heard the water cooled engines by Deutz weren't as reliable or efficient. Are these engines any more expensive or complicated to work on than conventional water cooled engines? If I go this route I am probably going to get the shop manuals and wrench on them myself. It will give me something to do in the winter months. Also, arent all of the heads, jugs and some other parts interchangable between sizes, i.e. 4,5,6 cylinders. Also heard the 5 cylinder models dont balance out as good as the enen number cylinder engines, any truth to this? Thanks for the info, looks like I will be buying some more of these engines in the future. I already have a couple of the small ones that I bought used and use in some smaller, light duty applications. They have been good engines with the little experience I have had with them. Just wanting some advice before I chunk a bunch of money into more of them.

Brazilton KSA water cooled irrigation engine, like a boat engine, does not have any use for a fan. No need to use an air-water heat exchanger and fan to cool the coolant when you have a basically unlimited supply of 55 degree water to use for cooling.
Alsace 47°52'46"N 7°24'30"EFor those of you who run on diesel engines WITHOUT intercooler, have a google search on 'pantone' His system of injecting some kind of vapour has helped reduce consumption in many a case. Have to see it to believe it!
Too strong lobbies are fighting his invention.
That said, running a diesel with a water cooler that uses the cool water that is pumped is not the answer: this water is way too cool for the engine and produces temp stress and will ruin head gasket! An engine runs best at it's normal working temp which is around 80°C, you'll have to figure out what this makes in °F.... So ideal temp of water coolant is around the same temp. I have witnessed people using a big water tank to have enough heat exchange surface instead of the radiator fan.... It's your $$$ anyway.
My 2 cents.... DSMIHNMA: Don't Sue Me, I Have No Money Anyway!

SW KS, near Dodge CityMike, the intercooler they're talking about is what I call cooling coils. You have a dedicated, closed cooling system that circulates the water through the irrigation water flow to cool it instead of running it through a radiator. I'll try to find a picture later.
Phil
EDIT: I didn't explain that worth a crap. The dedicated system has a surge tank that sits where a radiator would sit on a regular motor. Coming out of this a hose goes into the block & 1 goes to the cooling coil pipes that are enclosed in the irrigation pipe. Then one of the pipes coming out of the heat exchanger goes into the motor. You use the exact same coolant in this system as you do in a normal radiator setup.

That is what I always thought. Had a chance to buy an 855 Cummins that came from a fire system in a factory. Only had 150 hours and it was all test hours as the fire system was not needed. Price was great BUT inside the water jacket I could peel the scale off with my fingers. Also had a IH M that rusted a hole in the block from the inside. Man I bought it from said he only used water for its whole life. Never ran it in the winter so he saw no reason to put antifreeze in it. This is what I have seen "here". John
Texasfor what it is worth ,the smaller deutz applications have an oil cooler system .quite a bit diffrent from what we are used to with a deutz . they hold up well too,with less maintence .if you have a chance to look at an atlas copco compressor you can look at one.
Mount Vernon, WAWe are not talking about running the pumped irrigation water through the cylinder block. It would still use antifreeze and a thermostat to keep the engine at normal operating temps (I prefer 200 degrees F ).
The pumped irrigation water would simply be circulated around cooling coils which contain the engine's coolant. The engine thermostat would maintain the normal operating temp.
Mount Vernon, WAI do remember that discussion. I'll have to look that up in my old computer and see exactly what we came up with. I remember we looked at the Deutz, but I'm not sure whether it was water or air cooled. I'll you when and if I find that info.
Alsace 47°52'46"N 7°24'30"EThanks for the details of the cooling circuit..... So I have to understand that in place of a water/air heat exchanger, U use a water/water exchanger. great! ..... Got any pics to fix my mind?
When I was talking of intercooler, I was referring to the pantone thing. This system has difficulty with the intercooler to the turbo compressed intake. Have seen great pics of a french engineer that is vulgarising this system in africa: he installed it on a 300 HP CAT generator and wittnessed at least 20% less fuel consumption.... furthemore, the engine seems to have reborn to a new life and doesn't smoke any more.
Think that with ongoing price increase on energy, every cent is making a difference....
This guy is also thinking on how to build an affordable dual energy line so that diesel engines can switch to vegetable oil (raw pressed rape:cqnolla, sunflowers, etc... ) and back to diesel.

Subject: RE: Opinion of Deutz enginesWe have one in our combine we can get about 1- 1 1/2 galons per acre I have also heard the utilty size tractors get great economy. A guy about 5-6 miles away sold a fairly new tractor to go back to a much older Duetz for the fuel. Parts can be pricey but they last along time. Shop around on parts deals can be had there is a place south of GR Michigan that specializes in them.Redwrench

Subject: RE: Opinion of Deutz enginesthe Deutz is a well-built engine. Case used them in their old line of sheepsfoot rollers. The Deutz's fatal flaw in my experience is that the slightest malfunction of the air cooling system results in 100% meltdown damage. Be it as simple as a rusted or leaking air duct plenum or a dragging blower fan bearing, it will result in melted aluminum heads if the operator doesn't catch it in time. There is 0% margin for error, unlike a water-cooled system which can at least still absorb heat. And the replacement parts were horribly expensive.Tom Russell

Subject: RE: Opinion of Deutz enginesDid a little test last year while watering cabbage. The 105 hp Deutz tractor beat the 105 hp Deere tractor by 25% on fuel use. That is on the same pump on the same gun in the same field. Have bought 2 used Deutz this year and am now up to 9 of them fuel saving beasts. I will buy more when I find that certain tractor.. We have broken a few belts over the last 20 years and have never had a total meltdown. Had a guy run one atleast 6 hours and never had a problem with that tractor since. You need to clean the fins just like you need to keep a radiator clean. On parts you need to learn the places to buy them from. I get mine from the Doctor in Mo. I would go with a 912 or 913 series. I am told they have a forged crank and the 914 series has a cast crank. Stock Deutz parts are stong, I beat alot of pulling tractors who have more money spent on the engine than I have spent on the whole tractor. I have also been beat alot of times by them same tractors.

Subject: deutz tractorsyou probably run the older deutz, how do you get around the bad brakes that these tractors had? also would you consider the agco tractors, like a allis with deutz engine, or do you just stick to the true green deutz. Curious if you hold the new agco deutz power tractor in same regard as the old deutz.

5 Signs You May Need a Replacement Generator
If you’ve had the same commercial generator for a while, you may be wondering when the time will come to replace it. There actually isn’t a set timeframe on when you should retire your current system. A commercial generator can last 10 to 20 years or more, depending on the frequency of use and how well it was maintained. Keep in mind that a typical commercial generator is designed to last through many years of service. It’s possible that you could get 10 to 30 usable years from your unit. The exact number will depend on how well maintained the generator is, how often it is exercised, and how many running hours it has used.
Proper maintenance is the surefire way of extending the lifespan of a backup generator. Eventually, however, you may find that the system isn’t keeping up with your operations as well as it used to, and it may be time to purchase a new unit. Here are 5 key signs to look for when considering a generator replacement for your industrial facility.
It’s an Older System
The most obvious sign that a generator could need replacing is its age. If it’s more than a decade old, it’s probably experienced some wear and tear. Standby generators have an average life expectancy of between 10,000 and 30,000 hours. When maintained properly, many generators can work beyond this range, but you may experience more frequent breakdowns. At that point, you would need to weigh the costs of repairs versus replacement.
The first indicator that a generator is wearing down is often reduced efficiency. The system might struggle to keep up with the same load it has always handled. This issue could be resolved with a simple tune-up, but if you still notice problems with the system afterward, you should contact a generator professional from Valley Power Systems to assess the unit. We can let you know what it will take to get the generator running like new again so that you can make the best decision for your business.
For more information, please visit deutz generators.
Thanks to recent innovations, today’s gensets are much more fuel efficient and environmentally friendly than power systems of the past. They also come with advanced features such as remote monitoring to make power generation more convenient for the user. With remote monitoring, you can track generator status and perform diagnostics from anywhere via a smart device. If your current unit is outdated, you can reap the benefits of these technological improvements with a new standby commercial generator.
You Have Increased Generator Problems
Your backup generator may need replacement if you are regularly dealing with system errors and shutdowns. The purpose of preventive maintenance is to ensure the generator provides consistent and reliable power. However, if you are still experiencing frequent repairs even with periodic maintenance, now might be the perfect time to replace your generator.
Signs of decreased performance include power fluctuations, reduced power output, and slow startups. These can be incredibly frustrating to deal with during a power outage, and you may be left in the dark. You should also note that declining generators will consume more fuel than newer models to meet the same power needs. This will have a significant impact on your operational costs.
When a generator is increasingly unreliable, trying to keep it running will only cost you more money in delays and repairs. You should weigh the cost of continuing with this endless repair cycle versus investing in a brand-new generator that won’t require nearly as many repairs anytime soon
Your Power Requirements Have Changed
When buying a generator, many business owners focus on their current power needs without considering what the future might bring. As their business grows, their power needs increase, and the same generator is expected to take on the extra load. Over time, this will wear the system down and eventually cause it to shut down much faster than intended. If your business has expanded significantly over the years, it’s a good idea to invest in a new generator that will meet your needs now with some room for growth.
There’s Too Much Fuel Consumption
Another sign that your generator is taking a downturn is increased fuel consumption. Ideally, fuel consumption should remain relatively the same throughout the year if you don’t experience major changes in generator usage or powered equipment. You will find the expected fuel economy in the generator’s manual, but there are times when this number could decrease. If you have noticed an uptick in fuel consumption for the unit to do the same work it has done in the past, you should consider having the unit inspected to rule out any issues.
As a generator ages, its mechanical parts begin to deteriorate, making it less efficient over time. You can expect fuel usage to increase incrementally over the years, but an immediate significant increase in consumption indicates that something is wrong with the system. You should have it looked at by an industry professional to see if a replacement generator is in order. Replacing your old standby generator with a modern and energy-efficient one can help you save money and enjoy a reliable power supply year after year.
There’s Unpredictable Power Output
The whole idea behind buying a standby generator is to have access to consistent and dependable power. If the generator operates roughly, starts up slowly, or experiences power disruptions, these could be signs that a new generator is in order. When there is a power outage, a standby generator with an automatic transfer switch should start up within seconds of the power loss. If there are delays or trouble starting, you should have a professional evaluate your generator system.
Many things can cause a generator not to start up when there is a power outage. A generator specialist will be able to consider all of these factors during their assessment. In an emergency situation, the last thing that you’ll want to worry about is whether or not your generator will be able to keep your operations running. Having a power system that will start up and work as expected is essential to the overall success of your business.
Extend the Lifespan of Your Generator With Proper Maintenance
Preventative maintenance plays a crucial role in maximizing the lifespan of your unit. If you ignore your unit’s maintenance needs, it will break down much sooner than expected. Generator maintenance typically includes the following tasks and more:
Maintenance Requirements
- Oil change: Regular oil changes are essential to lubricate the different moving parts of your generator’s engine. Oil reduces friction between these components, which will help to minimize wear and tear over time.
- Filter change: Filters keep out harmful particles that could damage your system. Periodic filter changes will keep filters from becoming clogged, providing optimal airflow for your generator.
- Engine exercise: If you don’t use your generator regularly, you should have the engine exercised at every maintenance check. This will keep the battery charged and help service technicians identify performance issues.
- Battery inspection: A worn battery can cause power fluctuations that impact overall generator reliability. Your technician will inspect the battery and test power output to ensure your system is ready to handle your requirements during an outage.
- Leak check: Leaks can result in decreased generator efficiency, which can increase operational expenses significantly over time. However, some leaks can be hard to find on your own. Your maintenance technician will have the proper tools and equipment to identify hidden leaks and handle the repair promptly.
- Coolant refill: Coolant is essential to controlling engine temperature, so the coolant level should be checked at every visit. Fresh coolant will help keep the system from overheating, minimizing the risk of a power failure.
