8737 transmission is overheating

[Ivan223]

I need help please my 8690 have the same problem as my 8737 of overheating the transmission
I'm pulling a 12 row planter and I'm working 2 hours then it overheats

I pulled with both tractors a Ruben 10 and a karat 9 day and night no problems it's only when a hook the planter when the overheating starts

Are you selecting range 1 for field work
Is the oil level correct

 

[Ivan223]

Yes I'm working in range 1 and the oil levels are correct

Clean radiators?
Handbrake fully released?

 

[GFA]

Is the planter harder to pull than the other machines. What fwd speed and engine revs for each machine

 

[Ivan223]

Radiator are clean and the handbrake is released it wouldn't move if it was because bought 8690 and 8737 are Dyna VT

Yeah I get that it won't move if the handbrake lever is up,I'm thinking along the lines of the linkage further back may have something under/or sticking....

If you go forward and put in neutral will tractor keep rolling or does it stop a bit quick?

 

[Ivan223]

I hade the guys of MF here to have a look but no response out of them all what they have to say is its the steering pump on the 8690 and on the 8737 it's transmission calibration

Sorry its both tractors then

Are you running power beyond?

It keeps rolling and then stops

[Ivan223]

Power beyond??

 

[davidroberts30]

Pressure ,return and sensing line to control all the hydraulics

Does the planter require lots of hydraulic power from the tractor?
Would you have a photo of the dash panel/ warning lights when it is overheating?
Also what sort of electrical functions does the planter require, that are powered off the tractors power supply?

I've seen bad cab ground give false trans temp readings on the 8600 series.

What engine revs are you running with the planter? Can you hear the engine fan engage when the heat builds?

 

[Ivan223]

I'll have to go and check give me 4 hours then I'll come back to you

I can send you photos of the warning light
And yes the planter need 170 l per minute
I'm running the 20/20 precision screen

My rev is on 1600 and my work speed is 7.7-8kmh
I do hear the fan kick in and out

Hydraulic oil use shouldn't affect the transmission oil temp directly. Only if there were an interaction across the cooling pack. I would monitor the temps on the LCD, does the hydraulic oil have a reading, get a infrared temp gun on the transmission housing and the hydraulic oil tank to check.

Buy a fendt.
