Toro GrandStand 71504 - Adjusting the Deck-Lift Spring

Note: Rotate the bolt clockwise to raise the
deck; rotate the bolt counterclockwise to lower it.
3. T ighten the jam nuts and side bolts.
4. Check the front-to-rear pitch; refer to Checking
the Mower Deck Front-to-Rear Pitch ( page 53 ) .
Matching the Height-of-Cut
1. Check the rear tire pressure.
2. Set the height-of-cut to the 76 mm (3 inch)
position; refer to Adjusting the Height-of-Cut
( page 21 ) .
3. With the machine on level surface, position 1
blade front-to-rear .
4. Measure at A , and from a level surface to the
cutting edge of the blade tips ( Figure 85 ).
Note: The measurement should be 76 mm (3
inches).

surface
2. Measure the blade at point
A
5. If the measurement is not correct, locate the
front 2 yokes on the machine ( Figure 84 ).
6. Loosen the side bolt and jam nut of the yokes.
7. Adjust the top bolt of the yokes until the blade
tips match 76 mm (3 inches).
8. T ighten the jam nuts and side bolts.
Adjusting the Deck-Lift
Spring
Note: Adjusting the compression spring alters how
much the deck oats and the amount of ef fort needed
to lift the deck when using the height-of-cut lever .
• More spring extension reduces the lever lift force
required and causes the deck to oat more.
• Less spring extension increases the lever lift force
required and causes the deck to oat less.
1. Raise the height-of-cut lever and lock it into the
transport position.
2. Check the distance between the spring nut
and the rear side of the welded mount bracket
( Figure 86 ).
3. Ensure that the length is between 47 to 50 mm
(1.8 to 2 inches) as shown in Figure 86 .
4. If needed, adjust the distance by adjusting the
bolt on the front of the mount bracket ( Figure 86 ).
