MOW, MOW, MOW YOUR SLOPE, GENTLY DOWN THE GREEN

INTERLOCKING CHECK AND RELIEF VALVES INSURE SAFE ROADSIDE MOWING. THIS ARTICULATED-BOOM, HYDRAULICALLY-POWERED ROTARY MOWER ATTACHES TO MOTOR GRADERS AND POWER-SHIFT TRACK-TYPE TRACTORS. IT WILL CLEAN UP BRUSH AND WOOD GROWTH ON ROADWAYS AND RIGHT-OF-WAYS AND SAFELY PERFORM TREE-LIMBING AND- TOPPING FOR ROADWAY CLEARANCE AND POWER LINE CONTROL, THANKS TO CAREFULLY DESIGNED INTERLOCKS IN ITS HYDRAULIC SYSTEM. A DOUBLE VANE PUMP SUPPLIES 55-60 GPM OF PRESSURE FLUID AT 1750 PSI TO A 1-1/4 INCH SOLENOID- AND PILOT-OPERATED MOWER MOTOR VALVE, AND 10-12 GPM AT 2250 PSI TO A FOURSPOOL ARTICULATION VALVE. FOR ADDITIONAL SAFETY, ALL CIRCUIT LINES ARE IN THE BOOM, AND THE CENTER BOOM CYLINDER AND THE CUTTER HEAD CYLINDER ARE ENCLOSED TO INSURE PORTECTION. IF THE LOAD IS SUFFICIENT TO STOP CUTTER ROTATION, NO DAMAGE WILL OCCUR TO THE SYSTEM BECAUSE THE CIRCUIT IS PROTECTED AGAINST SHOCK LOADS BY A MAIN RELIEF VALVE SET AT 1750 PSI AND A MOTOR- MOUNTED CROSSOVER RELIEF OF SET AT 2250 PSI.
