TractorData.com Kioti DK40 tractor information
I have a 66", five shank, Dirt Dog Field Cultivator, which I pull behind a Kubota
L3560. The Dirt Dog and Fred Cain appear identical.
My Kubota, bare tractor, weighs 3,500 pounds. Your Kioti, bare tractor, weighs 3,850.
From my experience, with loaded tires, you will be able to pull five shanks or six shanks through unworked ground with some rock. I believe seven shanks will stall you out, IF YOU ARE PULLING AT 10" DEPTH. Shank assemblies are reputed to be easy to adjust for spacing between tines and remove. I have never done so.
These are tough implements, overall, however the replaceable, bolt-on points can snap off. I have snapped off two in two years, in Florida unworked, rock-free, sandy-loam. Replacements are available on e-Bay. Use new #3 X 1-3/4" plow bolts if/when you replace points. (Points inevitably loosen at first. Check for tightness every half hour or you will lose some in the dirt.)
Moisture in the soil decreases resistance.
