Model Path Note
This legacy Z-Force 50 guide uses the 759-05064 PTO clutch, 01005011P PTO belt, 02000653 deck belt, 01010168-0637 blades, and 918-04426 spindle assemblies. Keep this path separate from RZT 50, Z-Force 48, Z-Force 54, Z-Force S, and later Z-Force production families that may use different clutch, belt, blade, or spindle numbers.
The 01005011P belt transfers power from the PTO clutch to the deck. The 02000653 belt routes around the spindle pulleys on the mower deck. These belts are not interchangeable.
Before Ordering

FAQ
What PTO clutch fits a Cub Cadet Z-Force 50?
The Cub Cadet Z-Force 50 model numbers listed in this guide use the 01008434 PTO clutch path. The current service replacement is the 759-05064 PTO clutch.
What does the 759-05064 PTO clutch replace?
The 759-05064 PTO clutch replaces Cub Cadet and MTD part numbers 01008434 and 01008434P on compatible mower applications.
What PTO belt fits the Cub Cadet Z-Force 50?
This Z-Force 50 path uses 01005011P as the engine-to-deck PTO belt. Cub Cadet lists 01005011P as the service replacement for 01003968, 01005011, and OCC-01005011. Contact PTO Direct USA to inquire about this product.
What deck belt fits the Cub Cadet Z-Force 50 50-inch deck?
This confirmed 50-inch formed-deck path uses 02000653. The belt is approximately 90.9 inches long and 1/2 inch wide.
Why is 02000653 sometimes described as a 54-inch deck belt?
The 02000653 belt is used across more than one Cub Cadet mower and deck family. The model-specific Z-Force 50 parts diagram shows 02000653 on this 50-inch formed deck, so the complete mower model number and diagram path should control fitment rather than a broad product-page title.
What blades fit the Cub Cadet Z-Force 50?
This 50-inch deck path uses three 01010168 / 01010168-0637 high-lift mower blades. Each blade is approximately 17.9 inches long and uses a round center hole.
What spindle fits the Cub Cadet Z-Force 50?
The original Z-Force 50 diagram shows spindle assembly 618-04394. Cub Cadet currently services that spindle through the 918-04426 / 918-3129B spindle assembly. Three spindle assemblies are used on the deck.
Is there a full deck kit for the Cub Cadet Z-Force 50?
Not currently for this exact 01005011P / 02000653 / 01010168-0637 / 918-04426 Z-Force 50 deck path. Use the individual clutch, blade, and spindle links above, and contact PTO Direct USA to inquire about the belt products.
Is this the same as the Cub Cadet RZT 50 deck path?
No. The legacy Z-Force 50 and RZT 50 use different mower designs and different clutch and deck-part paths. Do not use an RZT 50 guide for a Z-Force 50 mower.
Is this the same as the Z-Force 48 or Z-Force 54?
No. Some legacy Z-Force models share the 759-05064 PTO clutch or 918-04426 spindle family, but their belt and blade paths can differ by deck size. Use the guide matching the complete mower model and deck size.
