Installing a John Deere Model 30 Hydraulic Tiller on a 318

This is my first time installing a John Deere 30 Hydro Tiller with 12" extension on my 1984 John Deere 318 garden tractor. I tried to cover the various steps of installation but my tractor has a 3-point hitch and I found that the upper arms of the 3-point were very close to the location of the OEM upper bracket attachment points. A tractor without a 3-point would bolt the OEM brackets to the rockshaft arms and attach the tiller lift arms to those bracket pins. I recommend finding a copy of John Deere manual OMM87099 "OPERATORS MANUAL 30-Inch Hydraulic Tiller".
