I have an 1978 11-32 Toro (model 57360) which runs fine but the cut was
too short (couldn't use at height setting lower than 4 out of 5) and it
scalps on the right edge of the cut. After much thought I finally raised
the cut height to reasonable though still short by installing tires 2"
larger than specified. But it still always cuts an inch shorter on right
edge than on left, and infrequently scalps on right edge very deeply, digs
up to 1/2" into dirt, like really below the level of the bottom of the
tires. I can't figure out any way it can do that. I see some of you
mentioning replacing deck every 10-15 years-- why? Toro parts are
preposterously expensive. Any ideas on what's causing the scalping?
