a couple pieces of L channel on top. so i could place 8x8x16" concrete blocks, or some 6x4's or 6x6's or rail road ties. i have a 2 bottom plow, but at times i do not want to plow. and trying to get the discs to cut in to depth that i want, it would be nice to have some extra weight so i do not have to make as many passes.
i have had no need to. but being able to adjust the "angle" of each gang. assuming 5 1/2 feet disc having 2 front gangs of discs and 2 rear gang of discs.
extra front weights on the tractor. disc can be much like a bush hog (rotatory cutter) and when ya go to turn up into a hill, you may find your front tires are off the ground. or as your back tires are still in the dirt and come up into the grass for dealing with a garden, your front tires may come off the ground some. or become extremely light in the front.
i been tempted to make 2 to 3 holes for spot were top link connects to disc. so i can lift the disc "higher" for transporting the disc through the hills on the this farm. vs having to adjust the top link. so when i go down and then back up a small hill, the rear of the disc does not begin dragging. other words easier to set disc down and redo a pin, vs turning the turnbuckle on top link multi times. granted if you have TNT (top and tilt) errr hydrualic cylinder for top link, that would solve things as well. you might think of welding a heavy duty chain for top link on disc. and then going to a U hook to a eye bolt for top link as well.
one thing i dislike about 3pt hitch discs. is when you go into a sharp turn. you need to raise the disc up. or risk cracking a disc. have been tempted to see how a tow able disc would work that had a couple wheels that raised lowered via hydraulic cylinder. tow able as in. disc hooked to draw bar and pivoted on the draw bar much like a trailer would. and see if the disc would track / move gently enough without cracking / bending the discs. then again, i do 180 degree turns on a dime with left or right rear tire. that may be a bad idea.
not sure what they are called, on some pictures i have seen here on TBN. i have not seen them. the disc i have. has some metal pieces that stick almost right up against each disc along there sides. and helps remove any mud / sticky dirt. or tree roots that might get caught up / hang up on a disc. i have bent a few, and had to heat up the metal and bend them back into place. but seems like a big saver for me. and keeping the discs clean enough of mud to allow them to do what they are suppose to do.
