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:
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™ helps to maintain your cutter clean
All the RC M and R Series Rotary Cutters have the patented Double-Decker™ design. The smooth dome-shaped decks provide easy cleaning and water runs off for longer product life. Deck thickness increases as the size and cutter duty level increases.
