A while back I saw a tiller in the paper. $500 for the tiller and a handful of other implements. Bought it.
The tiller is red, and has snapper written on it. Has a slip clutch on the intermediate shaft; appears about 42" wide. Chain drive. Has a ~2:1 reduction on the input gearbox, a ~2:1 reduction in the primary chain, and a ~2:1 reduction on the final drive chain. Total of about 10:1 reduction from pto speed. Spun way too slow for my tastes. Originally I regeared the intermediate to 1.75:1 and that made it usable. Still cut the yard into chunks rather than tilling it though. Eventually I turned the input gearbox around, making it a 2:1 speed increaser, which worked great. Ended up with a 2:1 reduction in PTO speed. This, however, made the slip clutch a pain to adjust since the shaft it was on was spinning twice as fast as designed.
I got rocks. I'm sure other people got rocks, but I got lots and big rocks. It's worn the tiller tines to near knife edges. No problem, says I. Every time I till I have the kids out there and they help gather the rocks. Every time it rains more come back. Well today I went out to retill a food plot, after having tilled it last week. Apparently a new and exciting rock surfaced, one that was roughly football shaped and sized. This was exactly the right size and shape to lodge in between two of the tine holders and pry against the shaft itself. Snap! The main shaft that all the tines are mounted to is snapped clean. Ouch! Unfortunately this is one of those things that no amount of slip clutch could have fixed; the rock wedged between the shaft itself and the guard, so it had tremendous leverage against the shaft but almost no increase in resistance to turning.
Anyway, now I have to weld it back together. Anyone ever heard of this tiller? Am I right on my guess that it's supposed to be hanging on the back of something smaller than my little 17hp kubota, with a faster shaft speed? For some reason I have this picture of a large lawn tractor with a 2000rpm pto shaft?
