Simple Device Fixes Hydraulic Down Pressure

Simple Device Fixes Hydraulic Down Pressure “Some seed drill equipment requires constant down pressure for seeding depth, and John Deere SoundGard cabs have little components to put in the tractor console to operate the hydraulic levers, but they don’t work very well,” says farmer Lorne Glanville. “Most hydraulics stay in position until the cylinder reaches the end of the stroke, and then they kick back out.” To solve this frustrating problem, Glanville created a small device to hold his tractor’s hydraulic levers in constant down pressure and lock the valve in the operating position. The device consists of a 5-in. long and 3/16-in. thick piece of flat iron welded at a right angle. Glanville welded a 1/4-in. rod to the top of the tractor’s hydraulic valve, where one end of the flat iron snaps into place and attaches with a hairpin. The other end bolts into an existing threaded hole at the back of the valve. “It works for all 30, 40, 50 and 60 series SoundGard tractor cabs,” Glanville says. “It took a couple of hours and some trial and error to get it right, but eventually, I got it to work perfectly. When I don’t need the down pressure, I just remove it.” Contact: FARM SHOW Followup, Lorne Glanville, 82578 North Line, Walton, Ontario, Canada N0K 1Z0 (ph 519-531-1943).
