BOUGHT A RIDER WITH HYDROSTAT DRIVE,NO DRIVE BELT,HAVE NEW BELT BUT NOT SURE HOW TO RUN

When you say Hydrostat, I automatically think lawn tractop. If this is correct, then the reason it is slipping and just won't go is that your main drive belt is worn and slipping and won't pull. Replace the main drive belt and make sure the belt tensioner is fine and your done.

bad transmission, bad drive belt, bad pulley lots of things could go bad try your belt first or take it to your nearest lawn and garden shop they'll uselly charge a 15 dollar diagnostic fee but 99% of the time they'll tell you what it is for sure

If, and I'm sure it is, like all other riders, remove the deck, turn the mower up on it's side and supported with a lawn chair or the like, it won't hurt the mower, remove the electric deck drive unit from the crankshaft by taking the center bolt out and pull it off, remove the clutch tensioner far enough to get the belt off it, then remove the belt from the motor pully and the hydrostat drive pully and pull the belt out towards the front. replace the belt with new one and put it back together.

check the belt, check the fluid, make sure the dump valve isn't open and that the brake is disengaging. then suspect a bad assy...

If it is an old belt, replace it. Also make sure all pulleys are tight and belt is in all of the belt guides.

If it doesn't move at all; I would check the drive belt first, then the belt idler pulleys. Just make sure that no one has put the hydro units in bypass mode so they could move the mower without the engine running without your knowledge..

mowre will start but will not go into gear shaft will turn but not engage how can i get to trany without complete breakdown of *** end

- remove deck
- remove seat and rear fenders
- pry off deck adjusting knob
- remove F/R pedals
- remove floor plate
- use jackstands to prop up entire right side of tractor
- remove (2) screws holding fuel lines on side of frame
- lift out gas tank, set alongside left side of tractor
- remove plastic fan from hydrostat
- disconnect the electrical connector for the electric clutch
- from the top-side - use a 3/8" drive rachet - stick it into the tensioner slot next to the idler, rotate it to take tension off the belt, and remove belt off hydrostat pulley
- from underside - remove front idler (next to electric clutch)
- from underside - remove the "right-most" idler off the spring tensioner
- from underside - remove the "left-most" idler off the spring tensioner
- now the tensioner can rotate fully to take almost all the tension off the extension spring
- pop the spring off the tensioner arm
- the belt should now be able to be removed from the machine

- reinstall in the opposite fashion
- note: to reattach the spring, connect a nylon cord to the spring, and pull it rearward and guide it onto the tensioner arm - you need to stretch it about 1"
- for reattaching the two idler pulleys to the tensioner, get someone to hold the ratchet so the tensioner is positioned for the belt being in it's most-loose position. You may need to wrap the new belt around the hydrostat pulley first, and assemble the last idler pulley and belt at the same time to complete the procedure.

No your trans is getting too hot clean the dirt and grass and fluid off of it and make sure the fan on top has all its blade and is turning with the belt.

I think you just need a new drive belt. This is easy to fit. Remove the seat and back cover to axcess it. The grinding noise could be the pully rubbing against the belt tentioner because the belt worn or to big. Hope this works for you.
