RC100 Series Rotary Cutters

The game has changed and the stakes have been raised!  Dirt Dog is proud to introduce the RC series rotary cutter line.  Developed and built in Commerce, Georgia, this trend-setting line of standard duty rotary cutters is available in 4-foot, 5-foot and 6-foot models.  The RC line from Dirt Dog is designed with tip speeds suitable to provide a clean cut and nice finish in light to heavy grass conditions while also being durable enough to mow through light brush up to 1-1/2 inches in diameter.  Many people might think “how can you improve on the basic design of a single spindle rotary cutter?”  Dirt Dog has answered the question loud and clear… create a pivoting A-frame that moves the point of motion away from the hitch area thereby elimination those troublesome pinch points… build a slight dome in the top deck plate to promote water runoff and prevent puddling and premature rusting… run the deck plate past the sideband and weld underneath to eliminate water from standing on the deck and to create one awesome looking smooth deck… make replaceable bolt-on skids standard issue on this standard duty cutter series and the list goes on.  When the field is crowded, you must take extra measures to separate yourself from the pack… Dirt Dog’s RC Series rotary cutters have raised the bar!  Contact your local Dirt Dog dealer to find out more on this exciting series of cutters.

Grapple Grapple    

 A-frame pivot mechanism 

The innovative pivot mechanism located at the base of the yoke straps provides an industry-leading 23° of motion to assist in mowing over rolling terrain… and, just as important, it eliminates traditional pinch points associated with hitching/unhitching experienced on many other rotary cutters.


Domed deck design

A ¾ inch vertical offset in the top deck plate along the center of the cutter may be difficult to discern with the naked eye, but proof is in the pudding… water runs off to the front and the rear thereby keeping the deck dry and rust free.


Smooth top deck

The top deck plate is extended over the side bands thereby making a nice secure ledge for welding the two pieces together AND it creates a super smooth top deck that is easy to clean when the cutting is done.


Replaceable bolt-on skids

Replaceable bolt-on skids are a “next level” feature on this standard duty cutter class when compared to the competition… they provide quick and easy replacement when out AND the skids provide added strength and rigidity to the cutter’s sidebands.


Cat 1 Standard and Quick Hitch

The RC Series is developed to fit both standard and quick hitch Category 1 mounting arrangements.


Three-year gearbox warranty

The RC series come equipped with a 3-year limited gearbox warranty (see op manual for complete details).


Front/rear enclosures

The RC series units come equipped with front belting and rear metal band enclosures as standard equipment.


Single beam tailwheel design

A single beam “stinger” tailwheel minimizes the risk associated with backing up or swinging into an object when mowing.


Segmented rear tire with replaceable bushings 

 The tried-and-true segmented rear tire with replaceable bushings for extended life means your cutter rolls through the toughest stuff and keeps on keeping on.
