MAINTENANCE
Gearbox Lubrication (Figure Mnt-0001 and Mnt-0011)
The Gearbox was filled with oil at the factory.
However, it is necessary that the operator check the
Gearbox before operations. The oil should be up
level of the Test Plug on the side of the Gearbox.
The Filler/Breather Plug is on the top of the
Gearbox. Fill through this Plug.
Check the oil level after operating long enough for
warmed oil to flow through the Bearings into the
lower Gearbox cavity. Refill to the test plug level.
Check the oil again before operation, after every 40
hours of mowing, and at the beginning and end of
each mowing season.
NOTE: Overfilling the Gearbox will cause pressure
to build up and cause Oil Seals to leak.
ATTENTION: If the Gearbox suddenly starts
making an unusual noise, stop at once, check for
leaks, and refill Gearbox as required.
Recommended lubricant for GR60 is NLGI-000
(P/N 00765444) (Mnt-0001). Gearbox capacity is 4
Quarts.

(PN 00769031). Use gear lube with EP additives
