  • Publication number: 20240175223
    Abstract: Skid-steer type power unit engageable with an implement using an attachment assembly including an attachment frame and a hitch. An arcuate frame member is located forwardly of the attachment frame and is engaged therewith in such a way that the frame member pivots about a vertical axis located forwardly of the frame member and generally centrally positioned relative to the attachment frame. The frame member pivots in response to actuation of a hydraulic cylinder. The power unit includes a system for transferring weight of the implement rearwardly onto the power unit. A belt-drive power-take off system on the power unit powers the implement's operation. An underbelly drop spreader is located between the front and rear wheels of the power unit and a brine delivery system distributes brine from nozzles located rearwardly of the rear wheels. A unique control panel permits operation of all systems on the power unit and implement.

  • Patent number: 11638396
    Abstract: A mower frame unit is operatively connected with a tractor device and the mower frame is moveable between a generally horizontal first position and a generally vertical second position. The mower frame is moveable from the first position to the second position via a hydraulic cylinder and piston assembly carried by the mower frame to pivot the mower frame about a transverse axis. The mower frame carries a tensioner assembly that is operatively connected to a lock assembly. The tensioner assembly serves at least two purposes. Namely, to tension a belt operatively connected to mower blade and to maintain a portion of the lock assembly in a locked manner when the tensioner assembly is in a state of tension.

  • Patent number: 11622501
    Abstract: A wide area mower with an open-box structure mower deck. The deck has a width from the left to right side of about 72 to 120 inches. The deck's length is about 24 to 70 inches. A left and right front wheel are positioned in front of the deck. The wide mower deck will flex, twist, or bend when one of the left or right wheels travels over uneven terrain while the rest of the mower travels over substantially level terrain. A cutting height adjustment mechanism is provided on the mower that allows an operator to raise or lower an entire left side or an entire right side of the mower deck to a selected cutting height. This is done simply by disengaging a locking mechanism and manipulating a lever on a four-bar linkage attached to each side of the deck and then re-engaging the locking mechanism.
