Deutz. Would you buy one?

My uncle has owned Deutz since the early 70's. A 4006 and now a 6006. Both have been very good dependable tractors, and yes they are easy on fuel. I overhauled the 6006 for him and didnt have a problem finding parts. In our area of Tennessee, Duetz is starting to make a come back as the New holland dealer is selling them now. Hope this helps.

My dad has a 4006 as well.   He used it on the farm with a loader for many years and when he got out of farming sold it through a local dealer.   Found it again last summer and bought it back.   Other then some minor problems(bad ball joint, alternator shot, leaking power steering box, tires), it ran like a top.   My dad had all the minor things fixed and new tires put on all the way around.    Seeing as this was the only tractor my dad bought new, and it survived on the farm when my brother was helping run things as he was (and is) very abusive on things, I would say you can't go wrong with one.   I wanted my dad to buy it back as he used to have a garden tractor seat mounted on the fender for me to sit in when we baled hay and I was too small to help stack.   They are very easy on fuel.   Every one I have ever talked to has said that about them.  

I have wondered about them myself.  I have seen 4x4 models around 50hp sell at local farm auctions for around 2000 and thought that that seemed cheap for a 4x4 tractor but I haven't been brave enough to buy one.  I heard the engines ae easy on fuel but I am not sure about the air cooled part.

I wouldnt be afraid at all to buy one , I put some hrs on a 6275 ,it was a good pulling tractor , the engines are some of the best out there , with decent matinance they run for ever ; have some lulls with the motors at the real job and they are going great ; Deutz dealers are around and Ive heard the parts are better than it used to be , and there are more dealers popping out too  

My FIL bought a 9170 this winter.  It's quite a horse for the money and even that big motor is easy on fuel.  It does take a football field or 2 turn it around though....

Its a nice motor to have, since you dont have to worry about a radiator but like its been said you do have to keep them clean. 9100 series are pullin machines and easy on fuel.

Allis dealer that I worked at had a 9170 FWA for their own farming and it was trouble free except for a piece of silicone that was floating in the fuel tank for a while and a loose hydraulic line under the cab. I didn't like changing the oil filters as they were in an akward spot and always made a mess. It was about the easiest starting and smoothest big diesel I've been around. Before and after every season I would take the covers off to blow out the fins but not once was there any amount of debris in them. They really liked that tractor but it did take some ground to turn around compared to the 8000 FWA series they had. They also had a 7085 that they really liked and it was a comfortable tractor to drive and very quiet.

I have 2 Deutz Allis tractors and an R 50 with the Deutz engine.

We all know that when it comes to operation and routine maintanance its one extreme or the other. Some people respect their investment for what it is and care for it while others run the p*ss out of their equipment with little or NO maintanance. I have only heard great things about these motors!!! Yes the Gleaners needed to be kept clean but wasnt that in the owners manual?? Ryan

Hi Ive owned 9670 9190 9130 7085 6240  and the big block 6 turbo irrigation pump small block 6 irriation pump V8 naturaly aspirated irrigation pump all excellent running engines just keep the fins clean check for mice and there nests also still have the pumps 9130 7085 and the 6240s

In comparrison I have 8070 8050 4w220 4w305 and the 9670 would run circles around all but the 305 and if you put the 9670 side buy side with the 305 it wouldnt be very far behind the big six 574 will really run but will eat 12 to13 gallons an hour

Deutz used to like to push the fuel efficiency of their engines.  During the last days of the "real" Allis-Chalmers, I spent some time looking for alternate engines to use in place of the Harvey engines.  The Deutz bare engine fuel consumption maps were nothing special to look at.  The B and C Series Cummins engines (new at that time) were significantly better.

The reason the Deutz tractors had good fuel efficiency in Nebraska tests had a lot more to do with low parasitic hp draws of their tractors.  Their hydraulic systems had very low output and their cooling systems weren't designed to handle the high ambient operating temperatures common in much of North America.  Their tractors of that era didn't offer shift on the go transmissions either, which do add slightly to parasitic hp loads.  The lack of those features made for good looking fuel economy numbers at Nebraska, but limited the real productivity of those tractors in many North American applications.

deutz engines are ok when used in the right area, they actually will last longer than a liquid cooled engine, we have put them on the dyno in 95 degree weather and you can pull the dipstick and the oil is warm to touch not burning like a liquid cooled engine, thats what makes them last longer, not to say they dont fail because they do but usually it is because the fins get plugged from debris either from a valve cover leak that was not fixed or fuel leak causing jugs to get plugged. we have overhauled a lot of deutz engines and have rarely been in the bottom half, and they are not cheap if you use genuine deutz parts but then again nothing is. the killer was knowone believed in the air cooled engine when allis and deutz merged and then they went backwards with the introduction of 9100 series with the old over under tranny when they had a good 6 speed powershift, so we lost a lot of customers, then they tried to paint them orange but it was to late. my 2 cents!

If these are so great why are some dealers afraid to take the air cooled Gleaners in on trade even?  My other point is if they are so great why don't we see more of them?  In recent times how many Duetz's do you see compared to Cummin's, Cat's, Deere's or Detriot's in stuff made by smaller manufactures.  I know of two Duetz tractors in the county that are junked because it cost more to fix them than they are worth.  Granted you have that with any brand with any brand but I doubt 1/3 of the AC's, IH's or Deere's are just given up on for that reason.  Like the hired hand says about different stuff "there's a reason they don't do it like that anymore".

The forrest green Duetz were simple but crude, I used a 10006 that belonged to a friend of mine back in the 80's and I didn't care for it.
