Mower will not move foward or backwards belt ok and turning fan and pully.

rubber smell is rubber belt burning
lock up could be stuck park brake

Check the drive belt, not the deck belt.

Hi, check that the drive belt, pulleys and shafts are all ok and that they are actually driving the transmission, hopefully you will see the problem. If the transmission is driving ok and the fwd and reverse lever is functioning as you said, the transmission may have failed. Also check the hydro release lever is functioning. Regards Phil.

hello, hello, Drive belt replacement for front drive mowers. remove the belt coved on top of deckand clean out grass,turn mower on side where carb is facing up,use a pair of vice grips on side of mower deck so the blade can stop,remove the blade,remove the belt cover and clean out the grass,remove belt from rear and front pulley pulleys. install new belt,put belt cover and blade back on,put front belt cover on, should work,if that is not the problem; wheels will not prepeal the mower,wheels turn only when raised off ground, Check the gears or groves on the inside of the wheel for access wear that is a common problem,check the axle drive gears to make sure turns ok, to check gear box if ok pull mower back wards while drive is engaged,if wheels turn backwards than the trams is bad,all of this is caused by the operator,by not disengaging drive while pulling mower backwards or by holding mower back not allowing to propel self completely,hope this helps,any comments welcome,thank you.

You may have a bearing that is locked up, check to see if you can turn all the pulleys freely. If you cannot you may have to replace the one you can't.

the drive belt pulley probably needs replacing or the belt popped off the pully

drive belt is not getting slack on trans pully when pedal is pushed down.check all belt guides on outside of pullys .also check for worn pullys if v in pully is not flat may cause belt to hang up may want to try to adj brake rod that moves pully that slakens belt .hope this helps

Your drive belt may be broke are you may have some linkage that's came loose take a hard look under your mower

the pully on the trans axle may of sheared the the drift pin and now is just spinnig on the input shaft

sounds like a bad drive belt
