Sickle Bar Mowers

Before you can have high-quality hay, you need a high-performance hay tool. That’s where Frontier Sickle Mowers come in.

Better Haymaking

In our video series, we'll show you industry best practices and examples of how John Deere hay equipment stacks up against the competition.

Sickle Bar Mowers

• Belt-driven cutter blades
• Adjustable skid shoes
• Cutting arm flexes up to 90 degrees, or as low as -45 degrees
• iMatchTM compatible

Features may include:

Adjustable skid shoes control working height

The adjustable skid shoes on the cutterbar make it easy to control the working height of Frontier™ sickle-bar mowers.

Belt-driven cutter blades manually adjust for added tension

The cutter blades on the Frontier™ sickle-bar mowers are belt driven with a manual adjustment for tension. 

Breakaway mechanism has been strengthened

The enhanced breakaway mechanism has been strengthened on the SB31 Series Sickle-Bar Mowers for improved cutterbar protection and longer machine life.

Cylinder stop redesigned

The redesigned cylinder stop can be raised from the operator station by a cable and attached pull rope. This allows the operator to raise the cutterbar fully to move around obstacles without leaving the tractor seat.

Knife and guard maintenance

The bolt-on cutterbar knife guards and the riveted sections on the Frontier™ sickle-bar mowers can be removed and replaced individually.
