Home-Built Coulter Cart

"The ones I looked at all had wavy coulters, which have a tendency to bury rather than cut stubble and are a problem to sharpen," says the Greenfield, Ill., farmer.
So Lamb built his own heavy-duty cart and equipped it with straight coulters that cut stalks into uniform 6 to 8-in. lengths.
He used heavy 2 by 6-in. tubing to build a bridge hitch that applies downpressure to the 12-ft. wide toolbar. He mounted a 3-in. hydraulic cylinder on each side so he can adjust downpressure as conditions dictate.
The cylinders raise and lower a 4 in. sq. heavy wall tool bar on which Lamb clamped 22 18-in. dia. straight coulters that he salvaged off various plows. They're spring loaded and set for 7-in. centers to match Lamb's grain drill and 20-in. corn rows.
He used stub shaft axles and hubs off an old Allis Chalmers corn planter and fitted them with 15-in. car wheels. He equipped the machine with telescoping axle mounts made out of two different sizes of box tubing.
"That's so I can get the front hitch ex-
actly level with the back hitch, depending
on what tractor I'm using to pull it," he says.
Lamb pulls his 12-ft. grain drill behind
the cart in fall when seeding wheat and his 12-ft. field cultivator or chisel plow and sometimes a culti-mulcher behind it in spring.
He generally runs coulters 3 in. deep and pulls the cart with a 140 hp tractor.
Out-of-pocket expense was about $2,000, including $25 apiece for the coulters.
