Converting The 48 Inch Mower To Side Discharge - Toro 74920 Operator's Manual

To Operate the Machine
Move the bypass to the position for operating the
machine (Figure 31) to engage the wheel motors.
Converting the 48 inch Mower
to Side Discharge
The mower deck and mower blades shipped with
this machine were designed for optimum mulching
performance. Side discharge performance can be
improved by replacing the mulching blades with
standard cutting blades obtained from your local
authorized Toro dealer. To maintain optimum mulching
performance, always install the mulching blades that are
shipped with this unit when changing back to mulching
operation.
Install the fasteners into the same holes in the deck they
were originally removed from. This ensure no holes are
left open when the deck is operated.
DANGER
Open holes in the mower expose you and others to
thrown debris. Debris thrown out of holes in the
mower can cause injury.
• Never operate the mower without hardware
mounted in all holes in the mower.
• Install hardware in mounting holes when the
baffle is removed.

the blade control switch.
2. Move the motion control levers outward to the
