I have an odd question for you ingenious farmers…..we have two good sized Athens offset disc harrows we use for food plot planting. We just put new plates on last week and as always, didn’t get them tight enough. According to Athens plow, they torque to 1,400 ft lbs. or a 200 lb man on a 7’ bar, lol. Three of the axles can be torqued this way with their plate wrench. One gang can’t due to the frame being in the way. I was debating different options and found Enerpac makes a torque cassette style wrench, but that is too expensive. A torque multiplier is too big to fit between the gangs and has no way for the reaction bar to work.
I thought about cutting another wrench out of 1” plate with different holes along the handle. Then make a bracket to temporarily go on the gang beams (4x6x1/2” tube). I could then add a hydraulic cylinder between the two. Do you all think a 2.5” or 3” cylinder would have enough pressure to tighten these axle nuts using the tractor SCV valves? I originally thought of using a power unit for like a dump trailer, but realized the disc is usually attached to a BIG power unit.
