5085M stuck in park, but was forced to drive it anyway

Ive never been in a tractor with this feature. Always one with push brake, pull lever to lock brake pedal. I hate when they try to improve easy.

My farmall 856 has a transmission lock instead of brake lock. Might be due to the weight of the tractor and/or presence of hydraulic brakes

@grsthegreat Yeah, I hope not to relive that experience again. I actually moved the tractor to intercept the rolling trailer and the hill only got steeper (much steeper) from where I was. The trailer and everything on it would have ended up as a bent pile of metal down in the woods, had I not stopped it.

Yeah, these tractors are kind of weird in that they don't have an old school parking brake. i.e. press down on a brake pedal and have it apply the breaks to the rear wheels via some sort of locking mechanism. The only means of keeping it from rolling is to either leave it in a low gear (engine off), or move the range selector into the park position.

My range selector won't go into the park position any longer, but I'm free to select ranges A - D, but it will only get moving in very low gears to overcome the "park brake". Once it gets past that first "notch" it moves more easily, but with that awful ratcheting noise as the parking pin "floats" over the teeth on the parking gear.

Good luck with the repairs, I feel your pain!

I wish you luck on your repair. I have doubts it will be repairable from the top cover, but possible. The 5m transmissions are very labor intensive if transmission needs to be removed. They have been reliable, but expensive when they do need work. The park should have held without damage in the situation in your picture. I am afraid something was ready to fail anyway. Any chance tractor was still rolling when park was applied?

I got the estimate back from the shop:

I'm not going to pay an additional $9k for park to hold on an incline! I'll pick up a couple of wheel chocks to throw under the rears if I ever decided to park on an incline again.


I'll for sure change the transmission fluid 1st thing after picking it up.

 

[MotorSeven]

That's a shame. We have nothing but steep hills and ridges here, so a tractor without a locking break & only a park mode would be useless. Be careful chocking those tires on inclines as that can be a dangerous task itself.

 

[pclausen]

I hear you. Most of the time I'll have the FEL on and an implement on the back. So I'll be sure to drop both when parking.

 

[BigBlue1]

Ouch. It's kinda surprising that if the cab can be removed and installed for $2000 that the other transmission work/parts will cost an additional $7000. It must be a very complicated transmission to work on.

Maybe time to consider trading that one in for something else.

Why? that JD has thousands more hours of use left in it. it IS a diesel, can't it be shut down in a low gear,
It is pretty hard to roll over / spin up a diesel that is in low gear adding chocks and putting the fel down with the bucket edge stuck down does wonders as well and just add chocks when necessary.

I would drain the transmission again in a shorter drain interval plus filter if there was much metal in the fluid though.

With some of the reports on new JD's and PDI mistakes I would save the money and keep the older Non emissions? tractor.

Many powershuttle transmissions, if not all, do not hold the tractor when engine off and transmission in gear.
