The DR Roto-Hog tiller is designed to be towed behind riding lawn mower a garden tractor or ATV. Unlike unpowered tow-behind cultivators, the Roto-Hog does not depend on the towing vehicle’s capability to float through the soil, and its own 36-inch tilling diameter is about twice as wide as that of large walk-behind tillers. The Roto-Hog’s engine is significantly stronger than that of similar competing tillers, and it’s equipped with several premium features to make it easier to function.
The Roto-Hog’s engine is. By comparison, a comparably powered Field Tuff tow-behind tiller has a Briggs & Stratton Vanguard engine which delivers 6.5 foot-pounds of torque. The DR tiller’s engine has a 3-quart fuel tank , dual-element air filter and a launching system. The engine’s power goes into the tines by means of a belt-drive system, and shear pins shield the engine and drive shaft in the event that tines experience an obstacle and prevent rotating; DR claims the pins are simple to replace and provides extras with the tiller.
The Roto-Hog churns a tilling path 36 inches wide and up to 7 1/2 inches deep using a maximum tine rotation speed of 230 rpm. Its 24 steel tines are bolo design, designed for deep tilling of average lands and made to resist clogging.
Actuator and Controls
Height alterations on the Roto-Hog are commanded by a powered actuator that raises and lowers the tines and supplies 250 lbs of force to maintain the tines set up and help them to dig into the soil. The actuator is powered by a rechargeable 12 volt battery and can be controlled by a remote controller with a cable long enough to reach the towing car. The Field Tuff tiller, in contrast, is outfitted with a manual adjustment lever, although the lever is long enough that it may be, at least technically, corrected from the towing vehicle.
The Roto-Hog’s overall width is 39 inches, and from front to back it measures 66 inches. It weighs 259 lbs, which is about 5 pounds lighter than the Field Tuff tiller. The DR tiller rides 14-inch pneumatic tires, and it features a proprietary”Smooth-Trak” hitch that absorbs shock and forward momentum from the tiller and keeps it from being transmitted into the towing vehicle.
