Finished my Cat 0-3point hitch for Wide Frames and Quietline Cubs. It's been a long road, a lot of engineering, designing, building and then re-designing till I have something I am happy with.
My goals when I started:
1. Build something that looked like it was built by IH for Wide Frames and Quietlines.
2. Build something rugged, yet safe to operate.
3. Build something that would mount without modifying the Cub.
4. Build something that would not prevent the tractor from being used for other jobs.
The lower lift arm bracket mounts to the three lower bolts in the rear end but also have brackets forward to the axles for additional strength. I moved the draw pins forward in front of the bracket to prevent problems if you put chains on the tires.
The lift bar mounts to the rock shaft like a sleeve hitch does. The upper lift arms mount with a rod or Frankenstein bolts in the standard holes in the Cub frame. I have two mounting holes in the upper lift arm bracket where it attaches to the lift bar coming from the rock shaft. One hole gives maximum lift while the other gives less lift but provides a slower operation on lift and drop so you can do a better job leveling ground with a blade.
The top link bracket mounts to 4 studs in the upper part of the rear end.
I had thought about using the same adjustable lift arms like all Cat 0 3-point hitches use, the ones that you have to disconnect to adjust, but Ken Weaver kept after me to do it right so I built my own design. They have a lock nut which you loosen and you can adjust up or down without disconnecting the arm. Thanks Ken for making me do it right.
I built all lift arms, brackets, added chains for stability.
Unit is really stout, handles the Gannon with no problem. Passed all stress tests I gave it.
When I built it I designed the upper lift arms to be under the fenders out of the way . You can remove the upper and lower lift arms with 4 pins and then remove the top link bracket with 4 nuts. That way you can switch to a mower deck for mowing and not have arms sticking out the back. When its plow day just drop the mower and hook up the 3 point arms and top link bracket in minutes and be on your way.
