Default Sears tractor keeps destroying pulleys

Hello

My Sears 1000 XLT tractor is driving absloulutely nuts . The pulley
that drives the left side blade keeps stripping. The pulley is
attached to it's shaft with a star connection. If I hit a root or
stick or for whatever season the blade is stopped the belt will keep
the pulley spinning and the connection is destroyed. The star opening
on the pulley gets every so slightly stripped and enlarged and begins
to saw away at the spindle destroying both within seconds. This
happens only on the left blade, never on the right. To replace the
pulley and spindle costs me about $60 each time. so far in the two
years that I have owned time machine this happened 4 times! Can anyone
tell me what going wrong ?


Sounds like you're hitting stuff that shouldn't be. _Something_ is
going to give if you hit something solid enough to stop the blade while
the drive is engaged. Don't know what you expect to happen???
