I bought a 72 inch KK II {all GEAR} tiller at TSC just 5 days ago, $1299 plus sales tax, supposedly reduced from $1599.
EDIT; Included PTO shaft with slip clutch ;END EDIT.
It tears up sod remarkably well, the only "problems" I am having are with the wretched HF quick hitch that I am trying to make fit. Right now hitching up is anything but quick and certainly not easy. Part of my desire to use this is that initially I didn't want to cut the PTO shaft, but it is coming to the point where I might as well, it is simple enough.
Anyway, I have it on a Century C42, same/similar as Branson 38, just slightly more horse power. My R4 (17.5Lx24) tires are loaded with rimguard, maybe 1,000 or 1,100 extra lbs there. So far I have only run it on the 1,000 RPM PTO gear, with the engine at about 1300/1400 RPM. In first gear the tiller pushes the tractor a bit, which is what made me realize that it is forward rotating.
I doubt that I will need the power of the 540 PTO gear and higher engine speed, as I get used to it I will try higher tractor speed gears.
It is SMOOTH ! due to the offset of each of the 9 sets of 6 tines, they hit into the ground in a staggered pattern.
Visit their web site and look up the parts manual to see how this is done.
They also have a 4 ft and a 5ft version, but I wanted to cover the full width of my tires and they didn't have the 5ft one in stock anyway.
