Removing The Mower Deck - Toro Z MASTER G3 Operator's Manual

Sharpening the Blades
When sharpening blade, pieces of blade could
be thrown and cause serious injury.
Wear proper eye protection when sharpening
blade.
1. Use a file to sharpen the cutting edge at both ends
of the blade (Figure 97). Maintain the original angle.
The blade retains its balance if the same amount of
material is removed from both cutting edges.

1. Sharpen at original angle
2. Check the balance of the blade by putting it on a
blade balancer (Figure 98). If the blade stays in a
horizontal position, the blade is balanced and can be
used. If the blade is not balanced, file some metal off
the end of the sail area only (Figure 99). Repeat this
procedure until the blade is balanced.

Installing the Blades
1. Install the blade onto the spindle shaft (Figure 99).
Important: The curved part of the blade must
be pointing upward toward the inside of the
mower to ensure proper cutting.
2. Install the spring disk and blade bolt. The spring
disk cone must be installed toward the bolt head
(Figure 99). Torque the blade bolt to 85-110 ft-lb
(115-150 N-m).

Removing the Mower Deck

Before servicing or removing the mower deck, the
spring loaded deck arms must be locked out.
Deck lift arm assemblies have stored energy.
Removing the deck with out releasing the
stored energy can cause serious injury or death.
Do Not attempt to disassemble the deck from
the front frame without locking out the stored
energy.
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Remove the height adjustment pin and lower the
deck to the ground.
3. Place the height adjustment pin in the 3 inch (7.6 cm)
cutting height location. This locks the deck lift arms
in the lowest position when the deck is removed and
the stored energy in the deck spring is released.
4. Remove the belt covers.
5. Remove the bolts holding the floor pan down.
6. Lift up the floor pan and insert a ratchet into the
square hole in the deck idler (Figure 100).
7. Rotate the deck idler clockwise and remove the
mower belt (Figure 100).
