Xtreme Outdoor Power Equipment X0423 PTO Clutch Compatible with/Replacement for Cub Cadet RZT17, RZT22, RZT42, RZT50, Tank M48-HN and Z Force 01008544, 01008544P, 717-04127, 917-04127, 01008544

What It Is

The Xtreme Outdoor Power Equipment X0423 is an aftermarket electric PTO (Power Take-Off) clutch designed to engage and disengage the mower deck blades on zero-turn and lawn tractors. It is a direct replacement for specific Cub Cadet models, including the RZT17, RZT22, RZT42, RZT50, Tank M48-HN, and Z Force series.

Fitment & Compatibility

Before buying, verify these three things:

• Model & Deck Size: This clutch fits Cub Cadet RZT17 (42" deck), RZT22 (50" deck), RZT42, RZT50, Tank M48-HN, and Z Force models. It does not fit all Cub Cadet mowers—cross-check your model number.
• OEM Part Numbers: Confirmed replacements for OEM #01008544, 01008544P, 717-04127, and 917-04127. If your original clutch has a different number, measure the shaft diameter (typically 1") and bolt pattern (3-bolt, 4.5" spacing) to confirm.
• Physical Size: The clutch body is approximately 4.5" diameter and 2.5" thick. Check clearance around the engine crankshaft and deck pulley.

Key Things to Know

• Quality vs. OEM: Aftermarket unit at roughly half the cost of OEM. Some users report shorter lifespan or noisier operation than genuine Cub Cadet clutches. Rated 3.5/5 from 4 reviews—limited feedback.
• Installation Difficulty: Moderate. Requires removing the mower deck, belt, and pulley. You’ll need a puller tool to remove the old clutch from the crankshaft. Wiring is plug-and-play if your harness matches.
• Common Gotcha: The clutch may not engage if the air gap is too wide (should be 0.010–0.020"). Check and adjust after installation. Also verify the belt routing matches your deck—some RZT models use different belt lengths.
• Warranty: Usually 1-year limited. Check seller policy before buying.

Should You Buy It

If you need a budget-friendly replacement for a Cub Cadet RZT or Z Force with a failed PTO clutch and you’re comfortable with moderate DIY installation, this is a viable option. However, with only 4 reviews and a 3.5-star average, expect potential quality trade-offs. For heavy commercial use or if you want guaranteed reliability, consider spending more on an OEM Cub Cadet clutch.
