A floating cutterbar helps make the new Case IH DC103 disc mower-conditioner easier to operate, adjust and maintain, the company says.

The new Case IH DC103 Disc Mower-Conditioner gets the job done.


Case IH’s new disc mower-conditioner builds on existing technology to help make hay production more efficient amid growing demand, the company says.

Company product manager for hay and harvest Tim Slater says the new DC103 model builds on Case IH’s centre-pivot Disc DC3 and the DC2 side-pull designs, but with new features including additional tilt adjustment and quick-change knives.

But the biggest change is a redesign of the cutterbar flotation, letting it float up when an obstacle is encountered which Slater says provides better protection to the knives.

In addition, each disc also has its own independent protection with a shock hub (frangible splines) that protects the main cutterbar drivetrain if it’s not possible to float over an obstruction.

"It’s a practical and user-friendly design that produces outstanding results in all conditions," he says.

"The cutterbar itself has a really robust design, with each disc having its own enclosed gearbox module. This makes the cutterbar very durable and is ideal for working on slopes as the oil doesn’t run to one end, but is instead retained in each module."

"Each gearbox module can also be serviced individually," Slater says.

Wide conditioning rollers match the width of the cutterbar, making the processing of the cut crop more efficient, while most in-field adjustments can be made without the need for tools.

The cutter blades can be changed by using a specific tool mounted on the mower-conditioner, featuring a quick-change design with a retaining clip and eccentric nut, Slater says.

 "The swivel hitch and driveline are designed for heavy application and with the double swivel gearbox there is minimal stress on universal joints at the tractor even while performing the tightest of turns," he adds said.
