How do you install drive belt on Simplicity REGENT 4211 riding lawnmower?

Answer 1

First remove the mowing deck entirely (pretty easy). Unplug the connection on the front, remove the center lug that whole drive unit will drop down and release the belt. There are two belt guides there, loosen them but you don't have to remove them. At this point the rear belt guide needs to be loosened but only on the left side, it's top mounted. Now your old belt should slide out. To install wrap the belt around the rear pully wheel and reinstall that rear belt guide. Thread belt around the pully tightners (I leave my e-brake on so there is less tension as I'm working). Finally wrap around the drive system, push that into place, tighten the nut and two guides.... done.

Answer 2

There is an idler tension arm located on the left hand side of the mower. Push this arm forwards to loosen the belt pulley and pull it forwards. The existing belt can then be removed and the new one fitted. Release the arm to tighten the new belt up.

Answer 3

I tried to take off the PTO to replace the drive belt but it wouldn't budge. Forget about taking off the PTO! It will save you time and frustration. What I did was take out the engine mounting bolts and lift the engine slightly. With it lifted about an inch I was able to manuever the belt onto the pulley. Doing it this way didn't take that long and I'm sure it cost a lot less than having a shop do it the "right way".
