Combines CR970 Complaints

[JHEnt]

I'm curious what was the reason they changed the engine control moduleIJ Did you think it didn't have enough powerIJ You say the engine temp limited your capacity. Was it the engine temp or the hydro tempIJ Many poeple apperently had trouble with the hydro temp, this caused the computer to destroke the hydrostat cutting ground speed. They traced this to a defect motor flush spool in the Saur_Danfoss hydro motor. If it was engine temp, what caused it to overheat. Did the screen choke up or the radiator. Did you have a screen brush installed on the combinesIJ When you plugged the machine, I assume you were running 400 rpm feederhouse speed. I would bet that the header feed speed was running material to the feederchain faster than it was taking the material up. With the NH 74C auger head your supposed to run the auger on the slow speed drive. The same works out better on the 73C heads on TR combines. This helps prevent slugs from tripping the stone door on TR's. I assume with wheat and oats that you had a draper head. I don't have any experience with those.

They will get better with time. last year the ones around here all had hydraulic problems and broke down in the field. The parts I know for at least one of the combines had to come from Europe and it was a 3 week delay. The farmer now onwns a JD. The bad part about the whole situation was that everybody knows it around here and makes them the CR look like n$@% to them.

You only solution then is a Cat lexion 480R. The Cat 3196, 431 gross horsepower engines stand up very well in extreme temps (Cat's years of experience with their engines used in the Special Application Ag dozers in the SW produce growing regions and the tens of thousands of irrigation engines running non-stop throug-out the summer). The Accelerate Pre-Separation system used in all lexion combines controls feeding and and limits the potential to plug while maintining industry leading capacity and the highest quality grain sample possible. My 485R handles a 36' MacDon with ease in the highest yielding greenstem soybeans possible, up to 20+ acres per hour at arond 1100-1400 bu_hour beans.

55 to 70 bushel beans and averaging 62.5 with a header not designed to really harvest soybeansIJIJIJIJIJ Maybe I'm a cycnic but your dealing with farmers here, not teenagers! JD

They changed the engine control module and tried everything else they could think of to get more power out of the combines that could only get 15 or so acres per hour when we were guaranteed 20+ acres per hour. Changing the module did not help however some software changes showed a slight improvement. We have delt with both engine and hydro overheating through harvest and both were detrimental to our productivity. As for our feederhouse speed keep in mind we have 700 hours on these combines and, to say the least, were not happy about their poor results. We have tried every combination of settings in an attempt to increase capacity and have decided that the problem is not related to setting. Our opinion at the moment is that the combine was not ready for production when it was put to production and it simply has too little power and too many other problems. Hopefully the '04 changes that are being fitted to them right now will cure some of the issues.

landSurfer, I'm assuming your header was a flex head. The one thing that our CR's can do right is thrash beans. We managed to blow away every machine we went beside including a chipped 9750. In numerous fields we averaged 30+ acres per hour in beans using a flex head in above average crops.

You need to get your stories straight, now which one of the following statements of yours is validIJIJIJIJ JD "They changed the engine control module and tried everything else they could think of to get more power out of the combines that could only get 15 or so acres per hour when we were guaranteed 20+ acres per hour." "In numerous fields we averaged 30+ acres per hour in beans using a flex head in above average crops."

try paying attention, he did good in beans and was whining about oats and wheat

 

[JD]

He never made mention to what you say. He claimed twice that they could not get over 20 acres and hour even after an update on the motor software and this was why they where so upset cause their where told to expect 20+ an hr. He never once said...except in....IJ or although in...IJ You can't have it both ways, either it performed or it didn'tIJ If your are naive enough to believe every thing some young'n posts, go to a chat room and get "jiggy with it" ! JD

 

[JHEnt]

He did say in the originol post that his trouble was in wheat and oats.
