Features may include:
- What is the best cutter for your job?
- John Deere rotary cutters lead the way with innovative design, superior performance, and proven durability. Valuable features such as the Double-Decker™ design and Max Flow cutting chamber prevent water and debris from accumulating on the smooth, dome-shaped top deck while the flat bottom deck absorbs the punishment from rocks and stumps.
- The top deck stays smooth - no dents, no dings, no holes. The internal supports sandwiched between the top and bottom decks are key to the smooth and structure-free Max Flow cutting chamber, while at the same time provide added strength and durability.
- To help promote safe operation, John Deere rotary cutters are equipped with front and rear safety-chain shields. John Deere rotary cutters continue to advance in value with powerful gearboxes, blade holders, and compatibility with a wide range of tractors.
- Here are situations when a rotary cutter provides value:
- Clipping pastures encourages grass growth, optimizing valuable pasture acreage.
- Cutting grass and stalks helps control insects.
- Routine cutting keeps weeds from reseeding.
- It is the most cost efficient way to cut roadsides, parks, cemeteries, airport fields, hydro, gas, and telephone easements, and all other types of open properties.
- Cutting grass waterways encourages root development and helps prevent erosion.
- Knocking down stalks such as cotton, corn, or milo speeds up decomposition. This is essential in no-till and minimum-till fields.
- Clearing out brush.
- Control undergrowth and grass in orchards, vineyards, and groves.
- Decide what model to use based on:
- The size of the area to mow versus the size of the machine – the bigger the area to mow, the bigger the mower needs to be in order to be efficient during mowing hours. Similarly, the limitation of a small area will guide operators to use a smaller mower.
- The amount of time and frequency it will be used – for longer hours and more frequency, choose a heavier duty machine.
- Tractor compatibility – if there is a tractor the operator will be using, look for the tractor compatibility sheet to identify appropriate options.
- John Deere rotary cutters are available in two duty-level categories:
- Mid-duty
- RC M models are available in 1.5-m (5-ft), 1.8-m (6-ft), 2.1-m (7-ft), 2.5-m (8-ft), and 3.2-m (10-ft).
- This duty-level category cuts brush up to 50.8 mm (2 in.) in diameter.
- Heavy-duty
- RC R models are available in 3.2-m (10-ft) and 4.2-m (14-ft).
- This duty-level category cuts brush up to 76.2 mm (3 in.) in diameter.
- RC6R is available in 1.8-m (6-ft) and the RC7R is available in 2.1-m (7-ft) cut widths; they cut brush up to 101.6 mm (4 in.) in diameter.
- Double-Decker™ frame design
- The Double-Decker design provides strength and superior cutting performance while reducing top deck rust. Two welded decks, each 3-mm (1/8-in.) thick, form the upper and lower surfaces of the rotary cutter frame.
- Internal stiffeners are sandwiched between the two decks, providing superior strength and rigidity.
