Subject: Deere 750 & 750B Dozers


Stoddard Co. SEMO		What are some pro's and con's of the 750's? How does the 750 or 750B Deere dozers compare to the Caterpillar D6 or D6B?

West TN		With these dozers being hydrastic drive and their age, I would be concerned about the condition of the drive train. Very expensive to work on and heat build up may be a problem in the summer time. I would prefer to have a D6C or D6D machine. Used parts and aftermarket parts are readily available for the Cat machines.

Yep great machine aside from the hydro. Ours got weak and slowly started leaking more and more. We replaced both transmissions a couple years ago with remans from BJ Hydraulics in Delton, MI. They were $5500 a piece. Like new now.

East Central Indiana		It was quite extensive and very messy, but not technically difficult. I took a lot of pictures for reference during reassembly. We removed the operators station with a loader, but let me tell you it was not designed to be easily removed. The only major problem i remember is getting the yokes pulled off of the tapered input shafts. BJ hydraulics told me exactly how to bleed and prime the new transmissions.

Stoddard Co. SEMO		I see alot of these on Machinery Trader, that are priced from $12-18k, and nothing negative in their discription. Is $16-22k a reasonable price range for a good 750 or 750B? For a dozer that weighs alot more than a D6B but, has a little less HP, there seems to be quite a price differance between the two.

Our 750 is never short on horsepower, in fact we never even run it wide open since someone put a straightpipe on it. Traction is the main limiting factor. Hydro torque is the second limiting factor, but it's rare for us to find that much traction.

I would be very interested in your pictures and lessons learned as this is something I need to do on my 750.  Email is good.

I currently have a JD 750.  I used to have a D6B and there is really no comparison in power or ease of use, the JD wins easily.  As someone else pointed out, a D6C would be good and D6D better.  As far as the 750 goes, I have to say I really like it.  Plenty of power and very nimble.  The hydrostats work great.  Mine are getting a little on the worn side but I have a spare set that has been rebuilt sitting on the rack in the shop.  Just waiting for the day when I feel very like doing it.  The 750 starts easy and does everything I need it to do.  Parts are readily available through various sources. 

I have had and rebuilt several dozers over the years.  One thing that you will find when you tear into them is that there is always a lot more work to do on older dozers.  As you tear them down, you find other things that should be fixed while you are in there.  Email is good if you have any additional questions.

SE IL / SW IN		I used to have a 755 (bucket instead of blade) that gave me good service. Very few problems,the only thing I didn't
like was could not keep it tracking straight, always seemed to be riding one pedal or the other. Didn't really hurt anything,you are just diverting oil, just aggravating.
