I asked this before but didn't have the numbers on the machines. The tractor itself is:H16/model 1656.
OH160 engine. The tiller number is/18614 01. My question is this. What drive shaft do I need. The tiller has a round shaft about 3/4 in diameter with a 1/4 keyway. It looks to me like either there is a part missing from the tiller. Or it hooks up different than I thought.
