Belt is stretched or the tension pulley
1) The drive belt could be broken. 2) The rearend could be bad 3) The brake on the rearend could be stuck. (this would make the rear tires lock up) 4) The pulley on the engine or rearend could be the problem. You need to do a little investigating to see what is going on where.
Use a puller so you do not bend the pulley.
I need to know how to remove a bolt from a pulley assembly on a Briggs and Stratton 8 hp vertical lawn mower engine. It seems to be rusty. I tied DW40 and vise grips and shaft slips. Any suggestions?
Not quite sure of the question, but I will give you a site I did (no ads, no nothing) and see if it helps:
Remove the belt(s) and manipulate the pulley by hand; its action should be butter-smooth.
Most lawnmowers loosen to the left. At least that's how I do it.
remove the varable speed pulley-replace both belts re-install varable speed pulley--your done.
A Murray riding lawnmower owners manual can be obtained from most Murray riding lawnmower dealerships. You can find the owners manual at most local libraries.
In order to replace the drive belt on a 42 inch cut Murray riding lawn motor, first remove the blade after disconnecting the spark plug. The drive belt is now exposed for easy replacement.
