There’s a Super Jr model to fit every job and every budget. The Super Jr comes with gasoline engine power options of 27 HP (20.1 kW) and 37 HP (27.6 kW). 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.

What should I consider before buying a stump cutter?

Factors to consider include the size of stumps you need to remove, the terrain and accessibility of your work area, the power and capacity of the machine.

What size stumps can a stump cutter handle?

Stump cutters can handle stumps of various sizes depending on the machine's size and power. Generally, they can grind stumps ranging from a few inches in diameter up to several feet in diameter.

How long does it take to grind a stump?

The time it takes to grind a stump depends on its size, type of wood, and the power of the stump cutter. Smaller stumps can typically be ground in a matter of minutes, while larger and more complex stumps may take longer.

What are the advantages of using a stump cutter?

Stump cutters efficiently and effectively remove stumps, eliminating tripping hazards, preventing regrowth, and clearing space for new landscaping or construction projects. They also reduce the physical effort and time required compared to manual stump removal methods.

Can stump cutters be used in residential areas?

Yes, many stump cutters are designed for use in residential areas. Smaller, more maneuverable models are available that can access tight spaces and minimize disruption to surrounding landscaping.

How do you maintain a stump cutter?

Maintenance typically includes regular checks of oil levels, sharpening or replacing carbide teeth on the cutting wheel, checking hydraulic fluid levels, and inspecting belts and hoses for wear. Following the manufacturer's maintenance schedule is important to ensure the machine operates efficiently and safely.
