I'm a novice when it comes to tractors, but mechanically minded otherwise. While mowing, the bolt and retainer on the left side of the load control shaft came off without me knowing it. When I made a turn the draw arm pulled off that end of the shaft (ripping the ball out of the arm). The right draw arm under load pulled the load control shaft into the transmission housing.

When I attempt to push the shaft back through the bushing on the left side it is misaligned low and to the rear. I know the shaft it supposed to sit in the fork above it but I suspect the fork may be out place as well.

Before I call a mechanic, I'd appreciate it if anyone could help me work through this on my own. I know I should replace the bushings and possibly the shaft, but right now I just want to figure out how to get things back in place. Though this is an old tractor, it has a little less than 4k hours on it.

Thanks in advance for any and all assistance!

JD does not recommend replacing the bushings unless absolutely necessary. JD worries since the bushings are press fit, excessive replacement could cause leaks.

Have you tried changing the position of the Load lever?

My worry would be you had key 20 and 27 fall off key 11 (2nd drawing) You would have to remove the rockshaft housing to check (1st drawing)

If the Load Control shaft moved into the transmission case that far, the hydraulic oil drained.

Remove the draft links and the Load shaft(#28) in previous post. You'll be able to look inside(with a flash light) to see if anything is out of place. If items(#20 & #27) are in place, I would think the Cam Follower(#17) may have come out of place, between the rock-shaft and lever(#2, in diagram below).

As Zebrafive stated, the rock-shaft housing will need to be removed, to place it in the correct position.

When I first heard a noise, I thought something was tangled in the finish mower I was using. I raised the deck to look underneath, then realized what had happened. I lowered the mower, and haven't tried putting the lever in any other position.

I guess it's possible the shaft bent, but it looks like I'll be looking for a mechanic. Tearing into everything is more than I'm up to these days.

Thanks for the help.

Cam Follower etc.

I'll see if I can get a look inside, but if it requires removing the housing, I'm probably going to let someone else do it. These days, it seems like every job turns into something bigger than it should have been, and Murphy's Law seems to always come into play.

Thanks for the information.

That did it!

I'll reiterate putting lever(key 28) in position "D" should remove pressure from arm so L/D shaft is easier to reinstall if other parts are in correct position.
Thanks a ton - that did the trick! You helped me once before and you've done it again. I'm up by the Red River, but if I ever get to Coyote Flats, I'll try to look you up and shake your hand.

Sorry I missed the load lever note the first time I read this. That did free things up.

Now I'm wondering, how will I know if the the parts you mentioned have fallen off? I've ordered parts to replace the damaged and worn external components, but would like to be sure of things before I fill the system up with hydraulic fluid.

Maybe probe with a magnet on a telescoping stick through the fill hole? :dunno:

Maybe pull the sump screen and see if you can look from that opening? :dunno: Never tried this so may not even be close to where the parts would fall to.

Thanks for the suggestions. I thought about probing with a magnet through the bushing to see if it picked up anything. If I don't find anything, and then reassemble everything and fill the transmission, what is likely to happen if theparts have fallen off? Will I damage something else or will it just no operate properly?

Please read flyweights reply #3 2nd sentence. Try looking in hole L/D shaft fits into utilizing a flashlight for presence/absence of parts. I'm guessing if one removed rockshaft housing the view of bottom of load control mechanism will be blocked by ring gear & pinion.

Nothing blocking view

Thanks. I have looked through the hole and don't see anything blocking the view. I also ran a telescoping magnet along the bottom of the case and did not attract anything. So, I'm hoping Providence is with me on this one. I'm still waiting on a few parts before I put everything back together and see what happens.

I appreciate all the input. I'm not as confident about tearing into things as I was when I was younger.
