I have a '74 110 serial over 300,000. I was mowing the other day and I stopped for a minute. I shifted back into gear and the tractor wouldn't move. The gear shift will not move out of gear now. The clutch doesn't release the rear wheels. With the clutch in, I can start the engine and the engine starts and runs fine. Shortly before this, I noticed the tractor was struggling to mow. I thought maybe it was heavy grass but apparently not.
I did a little searching and found this response to a member who had a '68 110 with a similar problem.
Sounds like you broke the stud ball off of the shifter. Does it feel loose when you try to shift or "stuck"? It might have gotten the broken piece jammed where it shouldn't be. Try taking the shift quadrant cover off and removing the shift lever cover and seeing if the shaft has the pivot ball and lower stud still there and let us know.
I was thinking something similar. I was thinking that a bearing started failing which caused an alignment issue and the tractor struggling. When the bearing finally came apart, pieces lodged between some gears and won't let the wheels turn.
If this is anything like I think, I will likely have to have it serviced. I don't have the tools or the skills to pull it all apart and fix it.
I can try to take the shift cover off and see what I can see. I also thought of either draining some lube out or sticking a magnet in and see if I find any metal shavings or pieces.
Any thoughts are appreciated.
