摘要： A stump grinding system that includes a vehicle and a stump grinder adapted to engage with the vehicle. The vehicle has a first end, a second end opposite to the first end, and a longitudinal axis defined therebetween. The stump grinder includes a chassis operably engaged with the vehicle at one of the first end and the second end. The stump grinder also includes a body operably engaged with the chassis and a grinder wheel operably engaged with the body and partially disposed outside of the body from the vehicle. The stump grinder also includes a drive assembly operably engaged with the grinder wheel and the body. The grinder wheel of the stump grinder is configured to rotate in a plane that is orthogonal to the longitudinal axis of the vehicle.

摘要： A boom mower having a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. There is a break-away mechanism that enables the cutting mechanism to pivot relative to the at least one translation assembly.

摘要： A boom mower attachment that moves a cutting mechanism in a first movement, a second movement, and a third movement by only using two motions of a single control and method of use thereof is provided. The boom mower may include a frame, a boom assembly carried by the frame, a cutting mechanism operably engaged with the boom assembly, and at least one translation assembly operably engaged with the boom assembly and the cutting mechanism that moves the cutting mechanism in one or more of the first movement, the second movement, and the third movement. An implement control system including a control, at least one function switching mechanism, and an implement is also provided. Activation of the control is operative to move the implement in a first mode, a second mode, and a third mode by only using two motions of the control.

摘要： An attachment system for removably attaching an implement under a vehicle. The mounting system includes a vehicle frame. The vehicle frame has a pair of spaced apart frame portions. Each of a pair of hitch receiving points is connectable with a respective one of the frame portions. An implement includes support structure extending for a length. A pair of hitch pins is associated with the support structure. The hitch pins are spaced apart in a direction along the length of the support structure. Each hitch pin is for attachment to a respective one of the hitch receiving points. A structural member is associated with the support structure and has a portion adapted to attach to structure outboard of a frame portion. A lift mechanism is connectable with a portion of the vehicle frame. The lift mechanism is attachable with the structural member to move the hitch pins relative to the hitch receiving points.

摘要： 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.

摘要： 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.
