HiTorque 130ftlb (OEM 105) BIGBearing Blade Clutch & 20A PTO Switch fits John Deere D140 D150 D155 D160 D170 E140 E150 E160 E170 E180 X135 X140 X146 X165 X166 GY20878 GY20939 GY22213 Mower Tractors

What It Is

This is a replacement blade clutch (PTO clutch) and 20-amp PTO switch combo for John Deere 100-series, E-series, and X100/X140 tractors. It engages the mower blades via the electric PTO, delivering 130 ft-lbs of torque—matching or exceeding OEM specs for residential and light commercial mowing.

Fitment & Compatibility

Before buying, confirm:

• Deck size: Works with 42", 48", and 54” Edge/Accel Deep mower decks on listed models.
• Model check: Fits D140, D150, D155, D160, D170, E140, E150, E160, E170, E180, X135, X140, X146, X165, X166. Not for older D-series (e.g., D100) or X300+ series without the same spindle/electrical design.
• OEM numbers: Replaces GY20878, GY20939, GY22213. Verify your clutch’s original part number (stamped on the old unit).
• Measurements: 4.5” diameter, 1” shaft bore, 3-bolt pattern. Measure your existing clutch’s bolt spacing and shaft diameter—some older decks may vary.

Key Things to Know

• Torque rating: 130 ft-lbs is 5-10% higher than OEM 105 ft-lbs, which helps with thicker grass or occasional bagging but won’t harm the deck.
• Installation: Moderate difficulty—requires removing the deck, pulling the old clutch, and wiring the new switch. Have a puller tool for the shaft; a torque wrench for the center bolt (35-40 ft-lbs) is recommended.
• Common gotchas: The PTO switch may need a minor bracket adjustment on some models (e.g., E170 with plastic dash). Also, the clutch’s bearing is larger than OEM—ensure your deck’s pulley clearance isn’t tight (check for rubbing on belt guides).
• Quality: HiTorque uses sealed bearings and epoxy-coated windings for moisture resistance. A few reviews note occasional vibration if the shaft isn’t perfectly aligned—re-torque after 5 hours of use.

Should You Buy It

If your John Deere’s PTO clutch is slipping, not engaging, or the switch fails, this is a solid, budget-friendly upgrade over OEM (typically $150+ for clutch alone). It’s best for DIYers with basic mechanical skills who want a drop-in replacement with slightly higher torque for tougher cutting. Skip it if you’re replacing a clutch on a high-hour commercial mower or need exact OEM fit without any bracket tweaks.
