Model Path Note
Cub Cadet Tank 60 model 53AH8STD050 uses the 01001979P PTO clutch, 00068079 PTO belt, 01005376P deck belt, 02005019 / 942-04415 blades, and 918-04939 spindle assemblies.
This mower uses two separate mower-deck belts. The 00068079 belt transfers power from the PTO clutch to the deck. The longer 01005376P belt transfers that power through the three spindle pulleys.
The 01001979P clutch is a commercial-duty replacement with a 1-1/8-inch crankshaft bore and an approximately 5.35-inch pulley. It should not be confused with similar-looking 1-inch-bore Cub Cadet clutches such as 01008434, 759-05064, or 917-05209.
The name Tank 60 was used near several older and later Cub Cadet commercial mower families. The complete model number remains the safest identifier. This page is limited to model 53AH8STD050.
Understanding the Two Belt System
00068079 PTO Belt

01005376P Deck Belt
The 01005376P deck belt routes through the deck’s spindle and idler pulley system. Cub Cadet lists this belt at approximately 122.3 inches long and 1/2 inch wide.
