my main mower is a MTD 50"GT, not my 128.
about 6 weeks ago my neighbor gave me a 10 yr old yard machines 42" 20hp
after he ran over some metal and tore up the deck saying it was done as a mower
(I had it fixed the next day but waited untill his new one arrived before using it)
my 50" gt is a push in the clutch to stop and brake
the yard machine you push the pedal to go ,with a brake above it.
so far I have mowed down flowers ,high centered it and crashed into junk in the garage .
