ABSTRACT:
A pavement cutting machine having a rotary cutting wheel with a generally horizontal axis of rotation where rotation of the cutting wheel is selectively controlled by a clutch on either the drive shaft of the engine or a driven shaft of the cutting wheel with the clutch being activated by a deadman's switch. The machine preferably also includes a stand that enables the entire machine to be tipped forwardly about its support wheels to expose the cutting wheel so it can be serviced. The clutch preferably is an electromagnetic clutch mounted to the engine drive shaft that is selectively energized by a deadman's switch on a handle of the machine that is constructed and arranged to close upon an operator gripping handle grips of the handle. When energized or engaged, a pulley of the clutch rotates in unison with the drive shaft, transmitting torque from the engine through an endless flexible member to a driven shaft carrying the cutting wheel causing the cutting wheel to rotate. When the handle grips are released, the clutch is deenergized or disengaged, decoupling the cutting wheel from the engine thereby enabling the machine to be safely left unattended with the engine running. The stand is preferably an elongate strut pivotally mounted to a forwardly extending portion of the frame of the machine and which is constructed to permit the machine to be tipped about its support wheels to expose the cutting wheel so it can be serviced.
