Well, the garden finally dried out enough on Wednesday to try out the new KK tiller... At one side of the garden, the moisture level was nearly perfect to work the ground... at the other side, it was a little wet yet... so I figured that it was a good enough time to test out the tiller, on both "ready to work" soil, and also on soil that was "just a bit too wet".
The tiller performed very well, as good or better than I expected it would, especially in the "wet" areas of the garden. I also tilled 2 passes of virgin sod on one end of the garden as well, just to see how it performed on sod also. I'm very pleased! It took me roughly 40 minutes to go over the entire garden 1 time. That's a lot better than the 4+ hours it takes with the TroyBilt Horse!!!
As far as a 6' tiller on a 27 PTO HP tractor (35 engine hp), my Mahindra 3525 handled it just fine. When I put the tiller in the ground, the tractor definitely knew it was back there, but it had ample power to run the tiller. I was not wanting for more horsepower. I wouldn't recommend the 6' for much smaller of a tractor, especially if you're going to be tilling sod or similar, but 27 PTO HP runs it just fine. One thing though, I had to tighten the slip clutch from the owner's manual's "recommended" setting. In the previously worked part of the garden, it worked just fine, and did not slip. But when I started tilling the sod, that was just too much load for it at the "recommended" setting, and it began to slip. So, I tightened all 8 bolts/springs on the clutch by 1 more turn, and tried it again. No slippage, the clutch was cool to the touch when I finished the 2 swaths on the virgin sod. 1 more pass over the freshly tilled sod, and it was tilled up as fine as the rest of the garden.
So, to echo so many others here on TBN, the KK gear drive tiller is a keeper!
Here's a couple of pics...
