S Series Geroler Motor, 7.30 cu in/rev, 4 Bolt Mounting Flange, 1 in. Straight Keyed Shaft, 1/2 NPT Ports, Compact yet powerful|Extended bearing life|Increased shaft seal

Four bolt mounting flange and a 1 inch straight keyed shaft are exactly what this motor carries, so from a fitment standpoint you're looking at a match on both counts. Ports are 1/2 NPT, which is worth confirming against your existing lines before you pull the trigger. The 7.30 cubic inch displacement will also affect your speed and torque output compared to whatever you're replacing, so make sure that lines up with what your harvester circuit is calling for.
