The RCB5710 Rotary Cutters are single wing mowers that are ideal for roadside mowing. The left-hand wing is replaced with a weight box on the RCB and the right-hand wing is replaced with a weight box on the RCBML models. This allows the operator to travel next to the road’s shoulder, remaining on more level ground. All the features you love from our 15-foot cutters are there too, in a 10-foot single wing model!
