According to John :
Hello

(multi-posted)


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 ?

Despite what others say, it should be able to stop momentarily without
destroying anything. I hit lots of things (rather rough ground in
places), and I've never had any damage (except for the blade getting
dinged of course).

Can you slacken off the belt a bit so it'll slip? Maybe it's too tight.

Agree about the belt. Over tightened belts will cause faster wear on
bearings, bushings, etc. I've seen this happen on alternators and
older car generators.
