Received new bolt, got the main drive pulley ready
It's the pulley for turning the blades, not for moving
the tractor..
Drove tractor up a set of car ramps..
Had to extend two wires and splice to the wires where
they ripped apart as pulley fell off tractor.
Put new bolt thru pulley, routed belt around pulley, lifted the assembly to output shaft of motor, tightened bolt which had a small drop of thread locker on it.
Made sure to fasten wires neatly out of the way.
