The double bottom plow is a custom build. Most of the larger cubs and green ones have the power to pull a twin 8" plow bottoms. Its getting that power to the ground that is usualy the issue. Guys have built both trailing 2 bottom plows, and 3pt semi mounted two bottom plows. But the single Brinly moldboard plow, with either a 8, 10 or 12 inch plow share is more common. I pull a 10" sleeve hitch mount plow with my Cub Cadet Original, and a 12" catagory 0 3pt mounted plow on our 782d diesel powered Cub Cadet. Keep in mind, the Original is only 7hp, but with ag tires, a set of IH wheel weights, I have no problem plowing in 1st gear and sometimes can run 2nd depending on soil conditions. Most guys dont mind puttting the hours on thier machines, some only see use at plow days and are not run much otherwise. Most of us do our own repair work and engine overhauling, so its not a real big deal. Most of these older Cub Cadets are found in tired condition, solid tractors, but with smoking or knocking engines. A simple overhaul with new rings, hone out the cylinder bore, or having it rebored if its out of spec, new gasgets and a carb kit is all that is needed to get the older K series Kohlers back to like new operation. I am rebuilding the mower deck for my Original so it can keep cutting the yard. These machines will be cutting yards and taking care of business long after we are all gone, with proper maintance.
