Hustler zero turn mower stopped all forward and backward movement. Engine runs and blades turn. When I try to move it just coasts as if in neutral.

usually if the pins are pulled out that is the freewheel position. push them in to drive. if the trans locks in drive and it is hard to push it should be ready to mow. unless the drive belt is stretched or broken or a linkage is out of adjustment or broken.

Check the drive belt, not the deck belt.

this sure sounds as if you have a seat switch issue , this is a safety device to make sure theres an operator that weights more than 115 lbs in seat , the blade engauge problem and non movement tells me this

Sounds like you have a Relay that is hanging up

If you are able to move in reverse but not forward, you need to adjust the levers. First you will need to elevate the rear wheels and set the neutral. This will then allow you to set the levers for proper forward and reverse movements.

Check your drive belt. May have broke or come off

check the connecting rod to the tranny. follow the gear handle and you should find a rod connecting the handle to the axle make sure you're in neutral and adjust the rod until the handle starts to move

Check the pump.Thanks for asking and I hope this helps out.Please leave me 4 thumbs up.

Check for a worn belt first.Then check the linkage. Next jack the unit up and try to run it forward and reverse with the engine running.If there is any movement at all in either direction then check the fluid level to see if it is up to the top.The worst case is the hydro. unit has a stuck check valve or something broken inside.Hope some of this helps. donnyb60
