HD Switch HiTorque 110 ft-lb PTO Clutch — BIGBearing replacement for Husqvarna/Poulan/Craftsman with replaceable bearing

HD Switch HiTorque 110 ft-lb BIGBearing PTO clutch is a higher-torque, heavy-duty replacement clutch designed to replace OEM 95 ft-lb units for Husqvarna, Poulan, Craftsman and similar lawn and garden tractors.

This premium PTO clutch upgrades the factory unit with a 110 ft-lb coil for stronger blade engagement and a larger, replaceable pulley bearing to resist the most common point of failure. It’s built to fit a long list of part numbers and deck applications, making it a direct-fit alternative when you need more holding power and improved longevity without modifying your mower’s spindle or wiring.

Will this clutch fit my mower model and OEM part number?

Compatibility covers many popular throwaway part numbers across Husqvarna, Poulan, Craftsman, Ariens and related brands. Check your mower’s parts list for matching OEM numbers listed with this product to confirm fit. If your model needs the alternate wire connector included, it comes in the box at no extra charge.

• Replaces: 532414336, 532179334, 179334, 414336, 532400008 and related OEM numbers
• Also cross-compatible with Ariens 04387900 and Gravely 04387900
• Fits specific Poulan and Husqvarna models such as PB20VA48, EZ4220, EZ4824, YTH2148 and many more
• Includes alternate wire connection required by select tractors

How does the HiTorque 110 ft-lb clutch improve cutting performance?

The higher torque coil increases blade engagement force compared to the standard 95 ft-lb OEM clutch, reducing slippage under heavy loads and giving more consistent cutting through thick grass. The stronger hold helps maintain blade speed on hills and in dense conditions, improving cut quality and reducing stall-related wear.

• 110 ft-lb coil provides greater holding power than OEM 95 ft-lb
• Reduces clutch slip during high-resistance mowing
• Helps maintain blade rpm for cleaner cuts and fewer passbacks
• Works with existing deck pulleys when compatible

What does the BIGBearing design change mean for durability?

The BIGBearing design addresses the most common source of PTO clutch failure: the pulley bearing. A larger, more robust bearing reduces heat and wear under load, extending service life. Importantly, the pulley bearing is replaceable, so you can service the clutch rather than replacing it entirely.

• Larger pulley bearing dissipates heat better under load
• Replaceable bearing lowers long-term maintenance cost
• Durable construction helps prevent premature clutch failures
• Factory-fit dimensions preserve installation simplicity

What else is included and do I need extra parts to install it?

The package includes the clutch assembly and an alternate wire connection required by some machine wiring harnesses. In many cases you can install this clutch using standard hand tools; however, check for specific spindle or deck compatibility before starting. If your mower needs a pulley spacer or special hardware not listed, keep those items on hand.

• Includes alternate wire connector where required
• Direct-fit for many listed part numbers — no modifications in most cases
• Replaceable bearing simplifies future repairs
• Verify model and deck type before installation

Who is this for? The HD Switch HiTorque 110 ft-lb BIGBearing PTO clutch is aimed at homeowners, landscapers and service technicians who want a robust, drop-in upgrade for worn or underperforming OEM clutches. If you own a compatible Husqvarna, Poulan, Craftsman or equivalent tractor and you want improved torque, fewer clutch-related failures and easier long-term servicing, this clutch is a practical upgrade that balances stronger performance with straightforward installation.
