Removing The Mower Deck - Toro Z Master 74925TE Operator's Manual

1. Sharpen at original angle
2. Check the balance of the blade by putting it on a
blade balancer (Figure 93). 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 94). Repeat this
procedure until the blade is balanced.

Installing the Blades

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 94). 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.
WARNING
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 95).
7. Rotate the deck idler clockwise and remove the
mower belt (Figure 95).
