Used about 20 minutes disengaged PTO and drove across road tried to engage PTO nothing happened and won't move forward or reverse. Hyd lift still works?
I'm leaning toward clutch just not familiar with hydrostatic transmission the mower would start slow and then speed up eventually even though it didn't seem to effect speed of tractor and then next time I engaged PTO nothing?
The way the 1810 is built the main drive shaft goes through the transmission and then to the pto. If you have no drive and no pto it has to be the clutch or couplings in my opinion. Is your clutch pedal adjusted properly? You should have around 5/8" freeplay at the top of the pedal before you feel contact. You can first make sure that is correct and if so I'm thinking a split is going to be in order. Here is Hoye's article. Yanmar Tractor Clutch Replacement
Wait for others to respond. Don't split it on my advice alone. I've been known to give bad advice.
