Abstract A pavement grooving machine comprising a truck and trailer with a yoke mounted therebetween, a housing having rotary blade pavement cutter means depending therefrom, the housing being horizontally rotatably mounted on and depending from the yoke, the housing being sufficiently rotatable to provide the cutter means with selective first and second pavement cutting positions opposed 180* relative to each other, whereby the rotary blade cutter means are capable of selective clockwise and counterclockwise cutting action. Otherwise, the rotatable housing permits the use of a bank of rotary cutter blades long enough to span a road pavement lane when in cutting position and rotatably retractable to another less space-consuming position when the machine is in transit.
A pavement grooving machine comprising a truck means and trailer means, an upright yoke connected between the truck means and trailer means, a bank of rotary cutting blades, horizontally rotatable support means for the bank of cutting blades rotatably dependingly mounted on the yoke between the truck means and trailer means, the bank of blades being dependingly mounted on the rotatable support means, the rotatable support means being sufficiently rotatable to provide the bank of blades with selective first and second cutting positions disposed at least 90* apart, the yoke including a substantially horizontally disposed beam carrying the rotatable support means, and a plurality of legs substantially at opposite ends of the beam, each leg being mounted on one of the truck and trailer means, said legs being vertically adjustable for selective raising and lowering of the beam.
