Hey, folks...I have had this old 1730 for about 4 or 5 years. I use it mostly in the winter for moving snow. I have forks for unloading trucks but not too often...anyway, I have hydraulic pressure to the arms and the bucket. It runs just fine. I just have no forward or reverse. This happened gradually until I had no movement. Plenty of fluid, no leaks. I understand that the drive system is akin to a snowmobile with the friction drive-type system. I took the seat off and saw what I thought was a hydraulic hose dangling in the breeze next to that pulley set-up. I am at a loss, here...I would think if that hose meant something, it wouldn't have taken it's sweet time to get to not moving. This was a couple of seasons in the making. Also, the HI-LO shifter I had to hold in the forward position with my knee in order to keep it in HI mode. Now that isn't a factor any more either...any ideas? Thanks...Mark

With the seat removed start engine and watch the shaft the belt is turning. Move the levers to go forward or back and that shaft should continue to turn, if it does not
the belt is worn and needs replacing and or the pulley needs repair or adjustment . Also that hanging hose might be off the variable speed drive pulley, it pressurizes
the piston in the pulley to increase travel speed. If the drive gradually got worse,, more than likely the belt and or the drive pulleys is where your problem is. If that
shaft continues to turn your problem is in the drive clutches which are contained in the side frames. You have to remove the large side covers to service them, Rod.
