Adjusting The Height-Of-Cut; The Safety Interlock System - Toro 31223 Operator's Manual

Adjusting the Height-of-Cut

The height-of-cut is adjusted from 2.5 to 15.8 cm (1 to
6 inches) in 6 mm (1/4 inch) increments by relocating the
stop pin into different hole locations.
1. With the engine running, push back on the deck lift
switch until the mower deck is fully raised and release
the switch immediately
2. To adjust, rotate the stop pin until the nub on it lines
up with the slots in the holes in the height-of-cut
bracket and remove it
3. Select a hole in the height-of-cut bracket corresponding
to the height-of-cut desired, insert the pin, and rotate it
down to lock it in place
Note: There are four rows of hole positions
16). The top row gives you the height of cut listed
above the pin. The second row down gives you the
height listed plus 6 mm (1/4 inch). The third row
down gives you the height listed plus 12 mm (1/2 inch).
The bottom row gives you the height listed plus 18 mm
(3/4 inch). For the 15.8 cm (6 inch) position there is
only one hole, located in the second row. This does not
add 6 mm (1/4 inch) to the 15.8 cm (6 inch) position.
1. Stop pin
4. Adjust the anti-scalp rollers and skids as required.

The Safety Interlock System

CAUTION
If the safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Understanding the Safety Interlock
System
(Figure The safety interlock system is designed to prevent the engine
from starting unless:
•
You are sitting on the seat or the parking brake is engaged.
•
The power take off (PTO) is disengaged.
•
The traction pedal is in the neutral position
•
The engine temperature is below the maximum operating
temperature.
The safety interlock system also is designed to stop the engine
when the traction pedal is moved from the neutral position
with the parking brake engaged. If you rise from the seat
when the PTO is engaged there is a 1 second delay and then
the engine stops.
Testing the Safety Interlock System
Service Interval: Before each use or daily
Test the safety interlock system before you use the machine
each time. If the safety system does not operate as described
below, have an Authorized Service Dealer repair the safety
system immediately.
1. Sitting on the seat, engage the parking brake and move
the PTO to on. Try starting the engine; the engine
should not crank.
2. Sitting on the seat, engage the parking brake and move
the PTO to off. Engage the traction pedal. Try starting
the engine; the engine should not crank.
3. Sitting on the seat, engage the parking brake, move
the PTO switch to off and allow the traction pedal to
return to the neutral position. Now start the engine.
While the engine is running, release the parking brake,
engage the PTO and rise slightly from the seat. On two
wheel drive machines, the engine should stop within 2
seconds. On four wheel drive machines, the mower
deck will shut off. The engine will continue to run.
4. Without an operator on the seat, engage the parking
brake, move the PTO switch to off and move the
traction pedal to the neutral position. Now start the
engine. While the engine is running, engage the traction
pedal; the engine should stop within 2 seconds.
