I bought this tiller for $75 about a year ago and just got around to messing with it. This is what it looked like when I brought it home.

I removed the plate the PO had put on there to mount an engine and fabricated a 3-PT for it. Then I had to put a brace in to make it solid so it would not pivot.

Next I fabricated new rails and a plate for the engine to mount on.

Next, I installed the new pulley. After talking to several people here I used an online calculator to get the right size to turn the tiller tines at approximately 200 rpm. I had purchased a Kohler 8HP Magnum on Ebay for $86 including shipping (got lucky). It has electric or pull rope start. I'm going to rig it up to start from the tractor battery as soon as I get some connectors.

Then I built this little bracket and mounted a belt tension idler pulley from a '98 Chevy pickup.

That's cool, Ronnie. Ought to tear up the garden real good when you get done.

Ok, this is my first try at posting videos. Hopefully, here's two of the tiller in action. It's going to take a little getting used to operating the speed of the tractor and depth of the tiller. We haven't had any rain in a good while so the ground is really hard.

Considering your breaking new ground that tiller is doing a nice job. Should work great once you have it all tilled once.
Nice conversion and you sure got a good deal on the engine as it sounds like it runs great.

Wow! Your churning some dirt there, Ronnie! Way to go! Glad you got the video thing figured out. I'll be looking for more now! Squirt a little water on there and it'll work easily next time!

Nice fabrication job on the hitch and engine mount. Boy is that thing kicking out the dirt. Maybe it's just the video but it seems to me that it's running a bit fast. If your soil is good and you have the power it won't be an issue. If you have rocky soil the speed looks a bit high to me.

Ronnie, You might want to plow that ground first then till it up. I'm with JD., wondering if you might be turning the tines a little fast. You were throwing a rooster tail out the back. Looks like it's doing the job. Very Nice Conversion!! :thumbs:

It kind of looks like she's running fast, but the engine doesn't sound like it. Plus it doesn't have a rear flap shield, so the dirt kicking back may just help make it seem faster. When I have the rear flap locked upward on my tiller, it too kicks out a rooster tail of dirt.
And that engine delivered for $86..........unreal deal!

Looking at the videos I know what you mean about the rooster tails out the back. Before I bought the pulley on the tiller I tacked the engine wide open, then rotated the tines on the tiller to find it had a 10 to 1 reduction in the drive unit. Then I selected a pulley that by the formula gave me 239 rpm. at full throttle. Wanted 200 which is the same as my Troy Built Horse but this is the pulley I found and can always throttle down. I think the fact that there isn't a rear flap like Daniel said is part of the reason it was throwing dirt along with the fact that that ground was unbroken and hard as a rock and I was going only 2 inches deep. There's no rock here, just black dirt and clay. I dug a 36 inch round well 30 feet deep and never hit a rock and have never hit one digging ditches or post holes. I'm going to stop by the shop when I get time and shear a piece of 14 or 12 gauge to make a rear flap for it. Thanks for all the comments everyone.

Nice fabrication there Ronnie. Great videos. Can't believe the price on the motor.Like Brian said, if you plow it first it would be just fine.
