Maintenance
WARNING
Hot exhaust system components may ignite gasoline vapors even after the engine is stopped. Hot particles exhausted during engine operation may ignite flammable materials. Fire may result in personal injury or property damage.
Do Not refuel or run engine unless spark arrester is installed.
1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
2.Wait for muffler to cool.
3.If any breaks in the screen or welds are observed, replace arrester.
4.If plugging of the screen is observed, remove arrester and shake loose particles out of the arrester and clean screen with a wire brush (soak in solvent if necessary). Reinstall arrester on exhaust outlet.
Thread Locking Adhesives
Thread locking adhesives such as “Loctite 242” or
•ROPS spring pin housing.
•Hydro pump control arm, linkage bolt, and attachment bolt.
•Hydro cooling fan screw.
•Hydro park brake cable anchor mounting bolt
•Sheave and clutch retaining bolt in the end of engine crankshaft.
Thread locking adhesives are required for some hardware on engines — see the Engine manual.
Copper-Based Anti-seize
On threads of Blade Bolts. See Check Mower Blades section.
Dielectric Grease
Dielectric grease is used on all blade type electrical connections to prevent corrosion and loss of contact. Dielectric grease should not be applied to sealed connectors.
Adjustments
Note: Disengage PTO, shut off engine, wait for all moving parts to stop, engage parking brake, and remove key before servicing, cleaning, or making any adjustments to the unit.
CAUTION
Raising the mower deck for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.
Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.
Deck Leveling
1.Position the mower on a flat surface.
2.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
3.Check the tire pressure in the drive tires. Proper inflation pressure for tires is 13 psi (90 kPa). Adjust if necessary.
4.Position the transport lock in the latching position.
5.Push the foot pedal all the way forward and the deck will latch at the 5 1/2 inch (14 cm) transport position (Figure 26).
