Will try again to post images and instructions.

Rotator key parts:
1. Ford car window motor (Amazon $29.00)
2. one side from bottom half of a PVC sink trap
3. 1 1/2" PVC pipe connector (Slips snugly over above part and is glued on other end to plastic face plate. Kept from rotating by the nail)
4. on/off/on toggle switch (Home Depot $5.00)
Lift motor key parts
1. GM window motor (Amazon $29.00)
2. 1 1/2" PVC pipe galvanize tread connector (Cut down wrench side to 1/16". Install inside plastic face plate.
3. two connectors from a PVC sink trap (grind down back side of one connector} Screws up to face plate on above part. Other connector is secured to tractor mount plate.
4. on/off/on toggle switch (Home Depot $5.00)
Inside the housing for both units is a short pipe welded to the rotating gear.
Hope information is sufficient. Also the design for a rotator might be improve by using the idea I used for the lift which eliminated the need for glue at the face plate. Enjoy.
