Can anyone help please? I have a MTD lawnflite 603/604 ride on and need to get the two belts off, how do I lock the engine up to undo the bolt holding the two pulleys on under the engine?
Many thanks.

There is a piston stop , that screws into the spark plug hole,
However they also make a flywheel holder , to keep the motoer from turning.
Myself I use an air gun and zip them out.
LUCK.

Thanks DG will give it a try most helpful cheers.
