John Deere 855 Drive Pedal Problem

[DougMac128]

Hi
I have a JD 855 hydro tractor. The drive pedals stick and do not return to neutral. If you do not set drive to neutral and get off the tractor it takes off. Any ideas. Tractor has done 2300 hours and is in generally fair condition.

Kind regards

Douglas

First thing is to look for any binding of the linkages and lubricate!

Run the front of your tractor up on some ramps.
Look up through the hole you will see in the bottom of the transmission case housing.
You will see a fork that a bearing rides up and down the side of.
The bottom of the V is neutral, you will notice a bearing, if this bearing is not free the transmission will not go back to neutral. This bearing and the pedal linkage of the two biggest causes of pedal trouble.
I have a PDF copy of the John Deere technical manual if you would like a copy. If so shoot me your email.

All linkages are lubricated and working. You have to apply substantial foot pressure to increase movement speed whether in forward or reverse.

Many thanks for advise and offer. I take it this is a standard bearing. Email douglas@rfidsystems.co.uk.
