Is it possible to put in a separate lever for the park brake on an 8000 series powershift? It's a pain to have to shift the range lever to neutral and the into park and then back again. Especially when stopping to open and close a gate before the cows get through. Obviously would still shift the range lever into neutral for stationary work.

It's a park LOCK, not a brake. And no, you can't have two levers. If you saw the way it was under the cab floor you would understand better. Maybe you need a couple of new cables to make shifting easier ??

I can't comprehend the trouble you think it is to "park" an 8000 PS. Two levers..clunk,clunk and you're there.

It's hard to describe the issue with this tractor. It has always been hard to shift the range lever out of low into neutral. Neutral to high or park works fine as does shifting it into low range from neutral. The gear selector lever is also stiff in this tractor, as in hard to shift 1 gear at a time. No difference hot or cold. I remember the cables being adjusted or replaced when it was still under warranty and they could never get it to shift like the others we had.

I should add that this tractor seems to have a lot of drag in the transmission. If I put the gear selector in neutral I have to keep my foot on the brakes or it will roll away. I always thought it was because this tractor is so much lighter than its big brothers but maybe that's not the reason. Would excessive internal drag make it hard to get the range lever out of low into neutral?

Ive got a 8070 i have to put the powershift into reverse to loosen up low range to get it out to neutral. I dont see it as a problem its just the way it is. Ive got another one that slides right out of low. I think new cables might help the firt one i just havent changed them yet

I know exactly what you're talking about. My ps 8050's do not like to come out of low range after I come to a stop, unless I do as stated above put transmission in reverse let the clutch out just enough to let the engine RPMs drop a pinch and then the range selector will slide out of low very easily.What you may try is using high range and a lower gear in the trans. All of my 70** and 80** tractors come out of the high range much easier than low range. I remember our old XT in front of the grinder mixer, you couldn't get the tractor and mixer through the gate out of gear brakes set and close the gate before something got out. We finally got a blue tick heeler, she kept the hogs in till I got the gate. One other option is stop the engine then the range selector will come out of low range quick fast and in a hurry. If I know I'm done with the tractor I don't bother shifting it into Park until after I shut it off anyway.

Also inside the valve body of the power shift there are three settings on the detents for the power shift. I had one that the spring broke and when we put it back together we put it in the position where it's the strongest detent. That was a mistake. It does shift hard and a little difficult to go one gear at a time until we got used to it. It does sound as though maybe your power shift cable may need an adjustment if your tractor is creeping in neutral. Does the fourth gear kick down feel like it's in the right place when you're shifting or when you push in the clutch does it kick down to Fourth gear?
Good luck.

Try shifting out of low right before you come to complete stop.

You mentioned the cables were replaced in warranty... that would have been around 40 years ago....

I have tried all sorts of different ways to get it out of low range and into park faster and they do help a bit. It's just that couple extra seconds that it takes to do it when I'm in a hurry. For the most part it's not a big deal I was just hoping it would be possible to just make a separate lever for the park lock to save a step. The inching pedal downshifts the transmission correctly and the transmission brake functions properly as well. If it would just stay where it is without having to put it into park that would be great. Sometimes I do just put the gear selector in neutral and jump out and hope I get the gate open before the tractor gets there, the colder it is the worse it creeps and the harder it is to get the range selector out of low. And yeah I realize that it's been 40 years since the cables were looked at but it didn't help back then and I am not convinced that replacing them now would make much difference. I will have to look at the agco partsbook to see what I can find in regards to the detent spring for the valve body. Thanks for your input guys.

The park and hi-lo are all on one short lever. I don't know how you could modify anything to make separate levers. My 8070 PS will creep cold in neutral but once warmed it will sit still without park no matter the range.

The parts are the same in the valve body. Their is a serial number break though.I had the detent spring break . If you could hold the shift lever perfect every gear was there but no detent. When we replaced the broken detent spring it has 3 settings. Soft medium and hard shift. Depends on how you set the spring. My mechanic and I chose the hard shift. I would not do that again. Just thinking this may be why your tractor feels different to shift.

I wish they would have put steps in the 1-6 that you could ride the lever with. I have went from 2nd to 4th more than once. Free handing the detents without resting arm against something results in skip shifts around here.
