Frequently Asked Questions

What tiller models does the King Kutter side gearbox fit?

The side gearbox parts fit King Kutter TG, TG-G, and RTG rotary tillers in 4', 5', 6', and 7' sizes. Because some fitment depends on your exact model and size, match the part number to your gearbox or confirm with the parts team before ordering.

What gears are available for the King Kutter TG side gearbox?

Broken Tractor carries side gearbox gears in three tooth counts: 16 tooth (SKU 902022), 28 tooth (SKU 902020), and 34 tooth (SKU 902021). The correct gear depends on the drive ratio in your gearbox, so verify the tooth count of the gear you are replacing before ordering.

What parts do I need to rebuild a King Kutter tiller side gearbox?

A typical rebuild uses gears, bearings, seals, spacers, and fresh hardware. We carry the Double Lip Seal Set (SKU 505017), the 3210C Double Ball Bearing (SKU 902018), a Self-Aligning Bearing (SKU 902019), retainer rings, spacer washers, and bolt sets for the TG, TG-G, and RTG side gearbox so you can source the components in one place.

Can I buy a complete King Kutter tiller gearbox instead of individual parts?

Yes, Broken Tractor offers a complete Rotary Tiller Gearbox for King Kutter 4' to 7' tillers (SKU 184069). If your housing, gears, and bearings are all worn, replacing the complete unit can be simpler than sourcing each internal part separately.

What bearings and seals are used in the King Kutter side gearbox?

The side gearbox uses a 3210C Double Ball Bearing (SKU 902018), a Self-Aligning Bearing (SKU 902019), and a Double Lip Seal Set (SKU 505017). These fit the TG, TG-G, and RTG side gearbox, and matching the part number to the bearing you are replacing is the surest way to confirm fitment.
