Removing The Mower Deck - Toro 74902TE Operator's Manual

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 96). Repeat this procedure
until the blade is balanced.

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 100).
7. Rotate the deck idler clockwise and remove the mower
belt (Figure 100).
