I recently bought a tractor off a guy who I see has made posts about this tractor. It doesn't really move when in any gear but in snail 1 it will roll maybe 1/4mph. I am fairly certain this is an issue with the forward/reverse clutch in the transmission. I believe the solenoids and everything are pulling in as the coils get magnetic when direction is selected. I verified the PTO clutch also engages to see if there is maybe a pressure issue but that still doesn't rule it out as there is much less going on in the PTO gearing. My question is am I correct in thinking that the transmission not going in both directions would indicate that it is likely not the direction clutch as it would likely only fail in one direction and this performs about the same in both. Don't have a pressure tester set up yet but maybe tomorrow I can get it running and find a gauge that will fit it. I see there are screens in the actual solenoid valve that I suppose could be plugged not letting a full pressure get to the clutches or my other thought is maybe a seal has blown in the clutch blowing by pressure but that I wouldn't think would affect both directions. I would rather not waste a bunch of time and money finding the clutch pack and splitting the tractor if this is just a hydraulic issue

As I see it, your tractor has a dry disc engine clutch. Your description of events leads me to believe therein lies your problem. Do you have any free play in the clutch pedal? If not, start right there. Lengthen the rod from the clutch pedal down to the lever it connects to and see what changes. Once you have some free play in the pedal and it still won't pull it's most likely a worn out clutch. Yes, a hydraulic issue is always possible, but the clutch is more likely the problem.
I had thought about that laying in bed last night. The guy I bought it from said his grandpa had put a new clutch in it not that long ago so it should be good and that there was plenty of adjustment yet in one of his posts he said it was at the end of its adjustments. I will have to look at it today. I originally before I bought it from the guy thought it would just be a clutch

I've never seen a power shuttle that didn't have a pair of wet clutch packs, that said it could also have a dry clutch. Without a service manual or at least a parts breakdown for the tractor it's just guessing at this stage.
Well I don't have to do any more guessing. I split the tractor today and found out exactly what went wrong. One side of the clutch disc blew up
