So I have seen posts here of three point hitches and hydrolic lifts/power at the rear. Are those custom jobs? I guess I am/was hoping for a "mini" tractor without getting into SCUT territory and price.
Nope, not custom at all. Nearly all Garden Tractors had an optional rear hitch. Whether it be a Category 0 three point hitch, a sleeve (one point) hitch, or something brand specific. (like older Sears, with a narrow 3 point, or the Homelite (Simplicity, rebadged) I pictured with its 3 point of a different configuration)
Most garden tractors have a shaft (rockshaft) mounted on the underside of the tractor, that have tabs welded to it. That shaft is attached to a lift lever (manual) or a electric or hydraulic cylinder. Those tabs are attached via cable, shaft, spring, rod, whatever, to lift an attachment. Or the rear lift.
First picture, a Case with the hydraulic lift cylinder attached to the rockshaft. Second pic, a JD 318 rockshaft pulled out of a tractor, and third, a Simplicity with the electric lift option. The electric actuator is the black cylinder mounted above.
