Handy depth adjust for 3-pt tillage tools
It only takes about 15 seconds to adjust the depth of 3 pt. mounted chisel plows, field cultivators or other tillage tools with Yeoman's "ripple system."
The rippled "male" bar has 20 ripples, one inch apart, on each side. It attaches to the wheel and slides up or down inside the heavy-duty serrated "female" casting which has 10 ripples, 1 in. apart, along each side. A simple steel "key" locks the meshed male and female serrations together at the desired height. To raise wheel height just pull the key, lift the wheel, then insert the key to lock the wheel at the new depth setting.
"Weight of the implement is carried by all 10 serrations, making it 10 times stronger than the usual depth control which locks at only one point," explains Alan Yeoman, inventor-manufacturer. "It provides vertical adjustment from 1.5 to 30 in. above ground."
The bolt-on casting fits 4 in. frames and is both left and right hand in one. It can be turned upside down to expand depth control range. "We could ship units, minus axle, hub and wheels, to interested FARM SHOW readers to save on freight cost. You could then attach the male unit to your own axle-hub assemblies," says Alan.
