The following steps are disassembly of the system,

including the steps necessary to replace the blade drive

and self-propel belts.

1. Drain the fuel and oil and tip the mower on its side.

We recommend carburetor side up to prevent any

oil or gasoline from draining into the air ﬁ lter and

causing hard starting.

2. Remove the two locknuts securing the blade (Fig.

205).

BLADE OVERRIDE SYSTEM (BOS)

BLADE CLUTCH SYSTEM (BCS)

Both Toro and Lawn-Boy use the same blade clutching

system on some models. On Toro it is named the Blade

Override System. On Lawn-Boy it is named the Blade

Clutch System.

It is designed to allow the blade to stop while the engine

keeps running. This is especially helpful when bagging,

as the engine will not need to be restarted each time you

stop to empty the bag.
