I was brush hogging with my 4630 today. I
was coming down a very steep hill in
1st/low and the hill was too steep so the
tractor took off and when I got yo the
bottom the wheels were turning in reverse.
Now I'm that if at first it doesn't go
right try it again type of guy so i tried
it again while braking slightly... same
thing happened. Only once at thr bottom
when i tried to shift, it wouldn't go in to
gear. Actually when I clutched it kept
going so i popped it out of gear. Turned
the tractor off put it in first and drove
up to drop off my bush hog. This time thr
clutch disengaged the transmission but when
i was done it wouldn't go back in gear. I
turned the tractor off. Put it in gear and
headed for the house. I decided to see if
the clutch would disengage it again and it
did. However this time i could shift in all
gears, h/l, but when clutch pedal is
released it doesn't engage the
transmission. Fluid is full (just did a
complete fluid change and put in the
recommend fluid). Pedal is moving
appropriately. What did i do? What do i
check?
 
A hot clutch disk can warp causing drag and failure to shift.
The tire turning backwards was due to the opposite tire gripping and turning forward. Differential action forces wheels to share rotation. If it was up on stands in gear and shut off, and you turned one wheel forward, the other would turn backward. I would avoid that hill until it was dry enough not to slide down like it was ice. Jim
 
If the tractor can't be put into gear with the clutch adjusted correctly for freeplay, it will need to be split. Looking at it without splitting is OK if you have an access cover to remove (I do not know if one exists on that tractor). Looking may be like taking the temperature of a dead crow. Good luck, Jim
 

Sliding over a hill with one wheel turning backwards won't cause any issues with the clutch.
If it has a input shaft seal leaking the steep down hill angle could have leaked oil onto the clutch disc.
How much pedal free travel does it have, should have 1 1/2-2", pedal should go about half way to the floor before the clutch releases.
Are you saying that now the tractor won't move with the trans in gear and the clutch out.
What trans do you have, 8x2 or 8x8 shuttle shift.
If the tractor will start in gear sounds like the neutral safety switch has been bypassed.
 
I don't think it was anything you did, probably just time for it to go.

The worst thing to do to a clutch is to ride the pedal, slipping the clutch as a means of speed control.

Or not keeping the freeplay adjusted, causing the clutch to not fully engage when the pedal is up.
 
This is 8x2. And yes now the transmission
is in gear and with the clutch out it wont
move. When i turned it off at first and put
it in gear i had the clutch down started
the tractor released the clutch and then
the transmission engaged. Then i engaged
the clutch put it in neutral, took the bush
hog off, tried to shift in gear while
running and couldn't. It was just grinding
gears. I turned the tractor off. Shifted
into gear, pressed the clutch pedal down.
Started the tractor. Then while driving to
the house, i pressed the clutch pedal, was
able to shift gears, when i released the
pedal this time however the transmission
didn't engage. Sorta like i had the clutch
pedal to the floor and wasn't releasing it.
 
I wasn't/haven't rode the clutch. As far as adjusting the clutch, that's something i haven't done. Ill look at my shop manuals and see if i can figure that out. I bought this last year at an auction and have used it to bale hay, 700 ish bales last year, pulled 6 logs with it, and did some work with a box blade. The clutch would always engage with pedal 1/3-1/2 way pressedto the floor and reengage about yhe same place when released.
