RG27 Super Jr ~ RG37 Super Jr

The Super Jr stump cutter is the original self-propelled, backyard stump cutter that professionals have relied on since 1986. Today, there’s a Super Jr model to fit every job and every budget. The Super Jr comes with gasoline engine power options of 27hp and 37hp. To maximize visibility while cutting, all Super Jr’s have the drivetrain located on the far side of the cutter wheel. And Rayco’s exclusive, swing-out control station gives operators the best view while cutting and swings in-line with the machine for travel through gates. Wide, floatation tires with bar tread give the Super Jr a firm grip on the terrain, and dual wheels can be added for extra stability. Rayco’s exclusive slewing ring pivot design lowers the center of gravity and lets the Super Jr cut at maximum depth across the whole swing path.
