Correcting a Mower-Deck
Mismatch
If there is mismatch between the blades, on a single
mower deck, the grass will appear streaked when it is
cut. This problem can be corrected by ensuring that
the blades are straight and all of the blades are cutting
on the same plane.
1. Park the machine on a level surface of the shop
floor.
2. Raise the height of cut to the highest position;
refer to Adjusting the Height of Cut (page
3. Lower the mower deck onto the flat surface and
remove the covers from the top of the mower
deck.
4. Loosen the flange nut securing the idler pulley
to release the belt tension.
5. Rotate the blades until the ends face forward
and backward and measure from the floor to the
front tip of the cutting edge.
Note:
Remember this dimension. Then rotate
the same blade so that the opposite end is
forward, and measure again. The difference
between the dimensions must not exceed 3 mm
(1/8 inch). If the dimension exceeds 3 mm (1/8
inch), replace the blade because it is bent. Make
sure to measure all of the blades.
6. Compare the measurements of the outer blades
with the center blade.
Note:
The center blade must not be more than
10 mm (3/8 inch) lower than the outer blades. If
the center blade is more than 10 mm (3/8 inch)
lower than the outer blades, proceed to step
and add shims between the spindle housing and
the bottom of the mower deck.
7. Remove the bolts, flat washers, lock washers,
and nuts from the outer spindle in the area
where the shims must be added.
Note:
To raise or lower the blade, add a shim,
Part No. 3256-24, between the spindle housing
and the bottom of the mower deck. Continue
to check the alignment of the blades and add
shims until the tips of the blades are within the
required dimension.
Important:
Do not use more than 3 shims at
any 1 hole location. Use decreasing numbers
of shims in adjacent holes if more than 1
shim is added to any 1 hole location.
8. Adjust the idler pulley and install the belt covers.

Storage

Preparing for Seasonal
Storage
Traction Unit
1. Thoroughly clean the traction unit, cutting units,
and the engine.
2. Check the tire pressure; refer to
Tire Pressure (page
27).
3. Check all fasteners for looseness; tighten as
necessary.
4. Grease or oil all grease fittings and pivot points.
Wipe up any excess lubricant.
5. Lightly sand and use touch-up paint on painted
areas that are scratched, chipped, or rusted.
Repair any dents in the metal body.
6. Service the battery and cables as follows:
A. Remove the battery terminals from the
battery posts.
B. Clean the battery, terminals, and posts with
a wire brush and baking soda solution.
C. Coat the cable terminals and battery posts
with Grafo 112X skin-over grease (Toro Part
No. 505-47) or petroleum jelly to prevent
corrosion.
D. Slowly recharge the battery every 60 days
for 24 hours to prevent lead sulfation of the
battery.
Engine

1. Drain the engine oil from the oil pan and install
the drain plug.
2. Remove and discard the oil filter. Install a new
oil filter.
3. Refill the oil pan with motor oil.
4. Start the engine and run it at idle speed for
approximately 2 minutes.
5. Shut off the engine.
6. Flush the fuel tank with fresh, clean diesel fuel.
7. Secure all of the fuel system fittings.
8. Thoroughly clean and service the air cleaner
assembly.
9. Seal the air cleaner inlet and the exhaust outlet
with weatherproof tape.
10. Check the anti freeze protection and add a
50/50 solution of water and ethylene glycol
anti-freeze as needed for the expected minimum
temperature in your area.
