I've had a couple members ask about my lift that's on a couple other posts. I told them I would make a thread to show the build, so here goes.
I had seen similar lifts on a snowmobile forum, but it didn't move. When you put the snowmobile on it, it was where it was until you finished. I wanted something more like a kid's wagon, that I could move around in the shop, or even roll outside to paint a tractor on. So with that in mind...
I took some small 6-inch wheels and front axle from a junk mower. Here's the front axle I made up:
Using 2-inch channel, I made the frame up:
Like the snowmobile lift, I used two parallel racks. this was the first mock up:
Then I made the "carrier", so it would fit any front-engine wheel horse. Almost all of these tractors are the same size between the foot rest bar and the tranny plate. That's where the carrier would need to attach.
I wanted it to positively hold the tractor frame, so I could take a tractor down to the bare frame, or start assembly of one the same way. The carrier locks onto the frame with a modified mid hitch:
All the pivots are on 3/4 hardened bolts. A little red paint, and here we are:
I used a $ 20 trailer tongue lift from TSC, and used it to raise the racks. It pushes from the back and passes through the braces on the racks.
I had originally planned on using an electric motor to turn the cylinder, but never found one with the torque to do it. Unloaded was fine, but with 500lbs on it, it just wasn't enough. So I made it manual, and made a "floating support" for the crank.
I used a UV joint from a Honda 4-wheeler at the crank:
I made a sliding brace to catch the racks at full up. It holds the racks up even if the jack breaks, and has to be pulled up to lower the tractor:
And I made full up stops so I never could go past the "push" side of the jack:
I also wanted to be able to steer this around, so I took the steering parts from the junk mower too:
I made a "t" handle, but wanted to be able to tow this with another tractor too. Just pop the pin and the hitch is ready, or stow it for pushing by hand:
So, use a set of ramps like this to drive a tractor on, and raise the tractor. Then remove the ramps and you're all set:
It raises the tractor about 30 inches, which was just right. No more broken back from tedious stuff: With the frame locked in, even rocking the stand over on it's side won't let the tractor fall off. It is VERY stable.
And that's it. It works great, and I wouldn't sell it for anything as long as I'm restoring tractors. Patents pending... Hehe
