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.

Required lubricant for GR72 is a SAE 85W140T (PN 00769031). Use gear lube with EP additives for extreme pressure and temperature, with a AP:- GI-5 Service rating. This lube also has tack agent added so oil adheres to parts when box is not running. (Mnt-0011). Gearbox capacity is 2 Quarts.
