I recently bought an 18315 tiller and it needs work. I assumed it should have a lift arm, but I downloaded the manual and it lists a lift cable instead. I am considering adapting it to work with the lift arm on my sleeve hitch and I am wondering if there is any reason I should not. I would guess the cable was used so if the tiller was bouncing it would not be stressing the lift assembley. I think if I used the sleeve hitch lift arm and only put a pin at the rear, it would be able to bounce without driving the rod forward. Just wanted to run this by you guys and see what you think.
