ENGINE MAINTENANCE
Refer to engine manufacturer’s manual, for servicing and maintenance of the engine.
EXCESS CROP BUILD UP
Remove all crop deposits from the deck and engine area. Build up of crop deposits could result
in heat build and fires.
NB:
Disconnect the spark plug lead.
Remove any crop that is wrapped around the rotors on the underside of the deck, as shown
below. Raise the deck to its max height to assist access to the rotor shafts.
VISUAL CHECK
Make a visual check around the mower, check for missing / loose parts or damaged / worn
components. All faults must be either repaired or replaced.
DRIVE BELT ADJUSTMENT
1. Remove drive belt covers by removing the 3x mounting bolts on each guard.
2. Slacken 4 x engine mounting plate bolts, so the plate is free to move (A) See figure 8.1
3. Tighten the tensioner bolt (B) until the tension on the belt allows one and a half the belts
thickness in deflection ether side of the belt centreline (C). Belt deflection should always
be tested on the longest and central part of the belt.
4. Replace drive belt covers.
NB: New drive belts stretch a little after the first few hours of use; so be sure too check belt
tension after the first few hours of use. (DO NOT OVER TIGHTEN DRIVE BELTS)
Replace any worn or cracked drive belts. Only use Logic specified drive belts as
replacements.
Always stop and switch off the engine and wait for the rotor blade movement to
stop before carrying out any inspection or adjustment. CAUTION some Drive belts /
Drive pulleys could be hot after use
