Have a Murray 20 HP riding mower, model 42572x8A (purchased new in 2001).
After about 10 minutes of riding it just slows down to a crawl whether the
blades
are engaged or not. Went through the following items but am stumped. Any
ideas???
Looks like either a motion belt may be stretching in the heat or possible
transaxle problems?
The blades and engine just roar along but the drive function slows. Also at
that point
it bogs down on even small hills. Is the transaxle completely sealed on
these
unts or can they be checked and fluids added? No visible fill points or
gauges on the
transaxle.
Replaced air filters
Replaced fuel filter
Changed Oil (no oil filter this model)
Replaced and regapped plugs
Replaced drive belt
Complete physical cleaning
All adjustments for forward, reverse, brakes made
Completely disconnected brake function as a test in case pads expanding
Tire pressure is fine
All lube points properly lubed
Carb adjusted
Removed deck to reduce weight and even put a lighter person on it
