Frequently Asked Questions

How do I know which King Kutter XB height adjuster kit I need?

King Kutter XB and XBX height adjusters vary by build date. We carry a Height Adjuster Kit for units built before 10/1/18 (SKU 501007) and a separate set for units built after 10/1/18 (SKU 501014). Check your cutter's build date before ordering, and match the part number or confirm with our parts team if you are unsure.

Does the tail wheel fork fit both XB and XBX rotary cutters?

Yes, our King Kutter tail wheel forks fit XB-series rotary cutters. We carry a Tail Wheel Fork (SKU 403023) and a specific XB fork for units built before 10/1/18 (SKU 403026), plus a Tail Wheel Arm (SKU 403700). Because tail wheel components can vary by build date, match your existing part number when ordering.

What blade set fits a 4' King Kutter XB rotary cutter?

We carry an OEM Rotary Cutter Blade Set for King Kutter 4', 5', and 6' models (SKU 501118-501130) that fits both Standard and XB rotary cutters. Broken Tractor also offers an OEM Blade Bolt Set with nuts and washers (SKU 501001) for XB cutters, so you can replace hardware at the same time.

Which gearbox do I need for a King Kutter XB rotary cutter?

King Kutter XB rotary cutters use shear pin and shear bolt style gearboxes rated at 40 HP and 60 HP. We carry a 40 HP Shear Pin Style PTO Gearbox (SKU 184005) and a matching stump jumper for both 40 HP and 60 HP gearboxes (SKU 403031-403032). Confirm your model and horsepower rating before ordering, or call our parts team at (800) 909-7060.

What is the difference between the smooth bore and shear bolt PTO shafts?

We carry a Smooth Bore / Shear Pin PTO Drive Shaft (SKU 147029-147034) and a separate Shear Bolt PTO Drive Shaft Replacement Kit (SKU 500101). The correct one depends on how your gearbox is protected, since shear pin and shear bolt setups differ. Broken Tractor also offers a PTO Drive Shaft Grease Fitting Set (SKU 132017) for maintenance.
