KO-KEN RATCHET

Ko-ken ratchets are known for their very low backlash, small head sizes, and high torque ranges. We designed the new 72 tooth ratchet without compromising on our traditional strengths. The patented design of the 72T combines the low backlash, small size, and has a 10% higher torque limit in comparison to the 36 tooth ratchet. The legacy 36 tooth ratchets move 10 degree/click. The new 72 tooth ratchets move 5 degree/click.

The design changes include moving from the single pawl of the 36 tooth design to the patented dual pawl of the 72 tooth design. The dual pawl 72 tooth design utilizes a single spring. We took four years of testing to perfect the low spring pressure needed to maintain Ko-ken's hallmark low-torque backlash. The finer 72 teeth design creates more surface area contact with the gear; thus, it has a 10% higher torque upper limit.

Direct replacement for my J Deere GT225
Fit my John Deere GT225 as a direct replacement. It did need to be re-gapped before installation. I think the price was fair for two spark plugs, now I have a spare.
