#2 Tiller Converted to Motor Driven.

[Ambush]

I got the tiller with the tractor but there was no mule drive, belts or corner drive for it. And since I had a fourteen HP motor already from another project, that set the direction. I wanted the input shaft on the opposite side for better centering of the motor which meant pulling the cases apart and flipping it over. It all came apart relatively easy. And then the bad news. The sprocket is welded to the shaft its configuration wouldn't allow flipping it over. The case, sprockets and chains were coated in what I believe to be open gear grease, but it cleaned up good.

I found a piece of 3/4' shaft that was long enough to stick out both sides, incase I ever wanted to revert to the original belt drive. Cut a keyway and picked up a sprocket and hub and got that welded up and new spacer made to keep everything where it should be.

It seems JD Corn Head grease is the lub of choice to fill the chain case. Happily I discovered we have a brand new farm and garden JD dealer in town and darned if they didn't have that grease. Cheap too!. Just guessing, I bought six tubes.

I put everything back in the case and with it laying on its side, I got all six tubes in there and I might have got one more in. I welded a 1/2" pipe bung in the top of the case for future filling if it's ever needed.

You can see the inputs in that pic too.

Now to get the motor to stick to the tiller. That turned out to be fairly simple as you can see in the pics. A piece of 3X3X1/4" angle catches five of the case bolts which I oversized to 5/16". A couple of struts and one bolt down to the shroud frame holds it all on there.

Its a 42" tiller and from what can find they all use an 8 HP engine. Since I have six extra horses in the harness, I decide to over speed the tine rotation. Most tillers turn 200 to 220 from my research. I'm geared to turn 260 at 3,000 engine rpm and the engine's WOT is 3,500. Theoretically, I should be able to increase my ground speed by about the same percentage. I ran it for a couple of minutes at WOT and it's fairly quiet and balanced. Once all the snow's gone and the ground dries up a bit, I can try it out!

Looks like a interesting project.

I just restored my 1a. I used nlgi 0 grease with moly. I ordered 6 tubes. I used about 1/2 a tube in the gear box. And 4 tubes in the chain case. I think it was shaffers brand. Seems to be very good grease.

Great job on the conversion there Ambush!
And thanks for sharing the details. I look forward to the action photos...
