Tractorsequipped with dual wheels may need the outside rightrear wheel removed. The RCP(M)3060 cutter requires adual wheel on the left hand side or wheel weights equalto the weight of a dual wheel.RCP2660 & RCPM2660 Minimum Tractor RequirementsFigure 1-1RCP3060 & RCPM3060 Minimum Tractor RequirementsFigure 1-212250TRACTOR CAB ORROLL OVERPROTECTIVE STRUCTUREOPERATORPROTECTIVESHIELD8,000 LBS.

Tractors not meeting the absolute minimumweight listed below must not be used.Basic Minimum: A right hand overturning torque load ispresent on the tractor when parallel arms are fullyextended. Tractors will need auxiliary counterbalanceweights added if the tractor’s total weight is less than thebasic minimum weight listed below.It is best to add auxiliary weights to the left rear tractorwheel. In addition, up to eight 100 lb. suitcase typeweights can be added to the optional weight hanger onthe hydraulic reservoir. However, adding weights to thereservoir can lighten the tractor’s front end.RCP2660 & RCPM2660Tractor absolute minimum weight . . . . . . . . 8,000 lbs.Tractor basic minimum weight. . . . . . . . . . 8,500 lbs.RCP3060 & RCPM3060Tractor absolute minimum weight . . . . . . . 12,000 lbs.Tractor basic minimum weight. . . . . . . . . 13,500 lbs.! WARNINGFront tractor weights and/or ballast to tires may be requiredto offset weight of cutter and auxiliary weights. Consult yourtractor manual to determine if additional ballast is needed.Wheel BaseRefer to Figure 1-1 & Figure 1-2:Rear wheel base must meet minimum requirementswhen measured from outside face to outside face of reartractor tires.

When necessary, addweight to the tractor front to stabilize it. Consult yourtractor’s manual for allowable added weights.IMPORTANT: The tractor’s right rear wheel shouldbe pressurized to the manufactures highestrecommended air pressure.
