Toro 52" deck with 19hp kawasaki engine runs fine when not under a load, when blades are engaged the throttle constantly goes up and down. I am assuming it is a governor problem, and have made sure the spring is still intact. How do I go about troubleshooting the governor?

SOURCE: I have a Toro zero turn commercial 60

im no expert but had a similar problem with an old craftsman mower. the belt keeper which is an L shaped piece of hardware located at the back of the deck next to the idler pulley spindal. Also could be the deck is cockeyed and needs to be leveled or the wrong v-belt.

sounds like your electric clutch is prob bad check to make sure wires are not bare touching something, the clutches do go bad eventually like any other electrical part, disc the pigtail and try fuse, if it blows then I would consider a clutch

SOURCE: toro 52 inch walk behind blades won't engage

if it has a electric clutch check for power to the clutch if no check the safety switches

SOURCE: Toro groundsmaster 120 engine kills when engaging blades at switc. Clutch? clutchWhat's your problem?

unplug wire form temp sensor on right side of engine and then try to engage pto
