Preparation For Seasonal Storage
Traction Unit
1 . Thoroughly clean the traction unit, cutting unit
and the engine, paying special attention to these
areas:
– radiator screen
– underneath the cutting unit
– under the cutting unit belt covers
– counterbalance springs
– PTO Shaft Assembly
– all grease fittings and pivot points
2. Check the tire pressure. Inflate all traction unit
tires to 12 psi (83 kPa).
3. Remove, sharpen and balance the cutting unit's
blades. Reinstall the blades and torque the blade
fasteners to 75-100 ft-Ib (102-136 N-m).
4. Check all fasteners for looseness; tighten as nec-
essary.
5. Grease or oil all grease fittings and pivot points.
Wipe off any excess lubricant.
6. Ensure that the PTO lever remains in the disen-
gaged position.
7. Lightly sand and use touch-up paint on painted
areas that are scratched, chipped or rusted. Repair
any dents in the metal body.
8. Service the battery and cables as follows:
a. Remove the battery terminals from the bat-
tery posts.
b. Clean the battery, terminals and posts with a
wire brush and baking soda solution.
c. Coat the cable terminals and the battery
posts with Grafo 112 X skin-over grease
(Toro Part Number 505-47), or petroleum
jelly to prevent corrosion.
