070-1000-00 PTO Clutch for Bad Boy Outlaw, Lightning, Pup & CZT | Warner 5218-220, 6.3" Pulley

Overview

This Bad Boy PTO clutch 070-1000-00 replacement is available in a Standard Black-Pulley configuration and an HD Upgrade. Both versions are built for select heavy-duty Bad Boy commercial mower platforms using the larger 6.3-inch pulley, 1-1/8 inch crankshaft bore, and CCW rotation.

This clutch path is commonly associated with select Bad Boy Pup, Lightning, Outlaw, Outlaw Extreme, Outlaw XP, CZT, and legacy ZT mower applications.

This clutch also replaces Bobcat, Bunton, and Ryan 4164976 on supported applications using the same clutch specification. It is commonly cross-referenced with the Warner 5218-220 clutch family and is designed to restore smooth blade engagement, reliable deck-drive performance, and consistent mowing power when the original clutch is worn, slipping, overheating, or no longer engaging properly.

Connector selection warning: The Standard Black-Pulley version has a flat side-by-side connection at the clutch body. It can connect directly to a matching mower harness or use the included optional extension harness to reach a T-style mower plug. The HD Upgrade has a lead hardwired into the clutch body that terminates in a T-style plug. The HD version does not have a flat side-by-side connection.

Important Bad Boy fitment warning: This is the heavy-duty 070-1000-00 clutch path with a 6.3-inch pulley. Do not confuse it with the smaller 070-0056-00 clutch used on many newer Bad Boy ZT Elite, Maverick, Revolt SD, Raider, and Walk-Behind applications. Both clutch families may use a 1-1/8 inch bore and CCW rotation, but the pulley sizes are different. Installing the wrong pulley size can cause belt slip, heat buildup, poor blade speed, and premature clutch failure.
