    I tried to take the one wheell off so I could insert the pin which connects the shifter but i could not get the wheel off when I removed the bolt.

    What brought it to my attention was I was cutting grass and it quit moving forward. I knew the belt was in rough shape so I tried to cut the rest of the section as I was not sure if I could get a belt. Played with the shifter putting it in reverse and than forward and it went for a while longer. Than it would not move aafter that.

    The reason I asked was there is a keyway in the axle and in the rim with a square key that locks them together. Sometimes people take off a wheel and don't see the key fall out. The mower won't move without it. Was the mower moving before you replaced the belt? Also, what is the model # under the seat?

    Did you have one of your rear wheels off while working on it?

Ok, I see it's and MTD product. Did you replace both belts? The front belt is #954-0280 and the rear belt is # 954-0370. What I would suggest is remove the cover plate between your legs. You'll have to remove the shift knob and two screws. Start the engine, put the gearshift in nuetral and let out on the clutch pedal and observe what's happening. Everything will be working the same as if you were in gear. You should be able to see if there is a problem with one of the belts or the vari-speed pulley. Put the speed selector in 7th (or 6th) gear and push the clutch down then back up, and watch what going on. That's the best I can do without seeing it myself. Hope this helps.

Trans bad?

Jack up the rear end using the frame. Put a person or cinder block on the seat, and put it in drive. Look for the shafts turning inside the wheels indicating broken keyways.

The tractor will not go forward or backward it starts right up but will not engage

1) The drive belt between the engine and transmission has broken or jumped off a pulley.
2) Your hydrostatic transmission is dead.

Cratsman lt2000 lawn tractor will start but will not move forward or backward. I tried changing the drive belt, but that didn't work.

Is the transaxle pulley turning? If so have you removed the rear wheel recently and possibly lost the square key that fits on the axle?check those two items first.If ok it probably has a broken gear or shift key in transaxle.
