This is a brand new king kutter finishing/grooming wheel fork. We just have finished production on these and are excited to be able to offer top quality aftermarket parts and more than reasonable prices!
This is an EXACT replacement part and YES it will fit your 4', 5', 6' or 7' machine.
It has a 1" round post with an 8" usable shaft with a pin hole at the top. It is 4" inside the legs and has a 3/4" hole for the axle bolt. It also has the axle bolt handle to keep it from turning on the fork.
