Harrow-Mounted Floating Cutterbar Helps Solve Residue Problems TILLAGE EUIPMENT Harrows 26-2-29 Residue from high-yielding small grain often causes problems after harvest because the stubble can be so long and thick that it's difficult for tillage or seeding implements to go through without plugging up. To solve the problem, Coombs Mfg. recently introduced a heavy-duty harrow equipped with a flexible floating cutterbar on front.
"It lets you mow stubble and work the residue all in one pass," says president David Coombs.
A 60-ft. model of the "Mow-Master" harrow was on display at the recent Spokane Ag Expo. The cutterbar is built in two sections and is powered by a pair of Schumacher hydraulic motors that operate off the tractor hydraulics. It takes four hydraulic circuits to operate the implement - one to operate the motor, one to raise and lower the cutterbar, one to raise and lower the harrow, and one to fold the unit for transport.
Cutterbar height is adjustable from 4 to 14 in. above ground. It mounts on parallel linkage, allowing it to follow the ground contour.
The Love floating cutterbar is a double-sickle system - a reciprocating sickle with 3-in. sections running over fixed 2-in. sections. "This design practically eliminates plug-ups and bent sickle sections so there's less breakage of sections and guards. It also runs quiet with less power demand.
"The machine also works great on CRP ground, where it can be used to stimulate grass growth and clean out weeds."
The unit folds to a narrow transport width of 10 ft. 11 in. A 48-ft. model is also available.
Coombs says the cutterbar adds about $10,000 to the cost of the company's 60-ft. harrow.
