Leveling The Mower Deck - Toro TimeCutter MX4275 Operator's Manual

Installing the Blades
1. Install the blade onto the spindle shaft
56).
Important:
The curved part of the blade
must be pointing upward toward the inside
of the mower to ensure proper cutting.
2. Install the curved washer (cupped side toward
the blade) and the blade bolt
3. Torque the blade bolt to 81 to 108 N∙m (60 to
80 ft-lb).

Leveling the Mower Deck

Check to ensure that the mower deck is level any time
you install the mower or when you see an uneven cut
on your lawn.
Check the mower deck for bent blades prior to
leveling, and remove and replace any bent blades;
refer to the Servicing the Cutting Blades (page 39)
before continuing.
Level the mower deck side-to-side first; then you can
adjust the front-to-rear slope.
Requirements:
•
The machine must be on a level surface.
•
All tires must be properly inflated; refer to
the Tire Pressure (page
Checking the Side-to-Side Level
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and move the
motion-control levers outward to the P
position.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Set the height of cut to 76 mm (3 inches).
4. Carefully rotate the blades side to side.
5. Measure between the outside cutting edges and
the flat surface (Figure
Note:
If both measurements are not within 5
mm (3/16 inch), an adjustment is required; refer
to Leveling from Side to Side (page

Checking the Front-to-Rear Blade
Slope
Check the front-to-rear blade level any time you install
the mower. If the front of the mower is more than
7.9 mm (5/16 inch) lower than the rear of the mower,
adjust the blade level.
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and move the
motion-control levers outward to the P
position.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Set the height of cut to 76 mm (3 inches).
4. Carefully rotate the blades so they are facing
front to rear (Figure
5. Measure from the tip of the front blade to the
flat surface and the tip of the rear blade to the
flat surface (Figure
Note:
If the front blade tip is not 1.6 to 7.9 mm
(1/16 to 5/16 inch) lower than the rear blade
tip, continue to the
