摘要： A shift mechanism for trim mower cutting units includes a pair of slidable carriers. Each slidable carrier can slide along a pair of guide rods mounted to a mower frame. A hydraulic extension cylinder is connected to each slidable carrier and independently extends to move the slidable carrier laterally outward from the mower frame or retracts to move the slidable carrier laterally inward in relation to the mower frame. A hydraulic shifting cylinder is mounted between the two extension cylinders and extends to shift both slidable carriers laterally inward toward a center position, and retracts to move both slidable carriers laterally outward toward an extended position.

摘要： A coupling mechanism for a reel-type mower cutting unit holds the cutting unit in a mowing position, a partially raised service position, or a fully raised transport position. The coupling mechanism is positioned to avoid blocking the discharge of grass into a grass catcher mounted directly in front of the cutting unit. Each reel-type cutting unit is positioned so that the reel axis is a maximum of 28 inches from the front wheel axis of the mowing machine when the cutting unit is in the mowing position.

摘要： A towable rotary mowing apparatus (10) includes a tow frame (30) for ganging together a plurality of rotary mowers (12) which are allowed to rotate about three axes (pitch, roll, yaw). The tow frame (30) includes a mid link (60) having opposite ends pivotally connected about side axes between first and second mowers (12) and having a carrier (66) for common components of the mowers (12). The third mower (12) is pivotally connected to a rear link (74) about a rear axis and which in turn is pivotally connected to the mid link (60) about the three axes. The control circuit of a control box (70) starts and stops operation of the mowers (12) by actuation of a handheld remote control device (120). A first timer (106) actuates a starter solenoid (108) for actuating the starters (100) and a second timer (110) actuates a choke actuator (112) of the engines (16) of the mowers (12).

摘要： A lawnmower with a tractor and a gang of mowers pivotally supported by the tractor for up and down motion when moving on the ground is provided. A mower support arm is pivoted on the tractor and has a pivot axis for each of the mowers, and a camming action is created by the up and down mower movement and that causes the pivot axis to move horizontally relative to the tractor to thereby avoid having the mowers move horizontally, and it maintains a constant spacing between the mowers and avoids having the mowers collide when moving up and down. Shorter length mowers can thus be used in the gang, thereby following the ground contour more closely.

摘要： A mowing apparatus with multiple articulating cutting decks includes a support for the cutting blades which is attached at a first side to the mower to pivot about a horizontal axis, and is carried by a rocker arm at an opposing second side. The rocker arm has ground support wheels at its opposing ends and is coupled to the second side of the support by linkage that is adjustable to vary the position of the support member relative to the rocker arm and to vary the height of the cutting blade from ground.

摘要： A frame for ganging a plurality of individually powered rotary lawn mowers together for towing by a vehicle in cutting lawn or the like has T-shaped draft bars which have cross-bar portions pivotally attached to the brackets of skid units mounted to the forward ends of off-the-shelf rotary mowers. Skid units are additionally provided on the rearward end of a first lawn mower, which has the tow bar of its T-shaped draft bar pivotally attached to a vehicle for towing. An intermediate elongated draft bar is attached to the brackets of the first lawn mower's rearward skid units. The tow bars of second and third lawn mowers are attached to the intermediate draft bar on either side of the first lawn mower such that the respective cutting paths of the second and third mowers at least slightly overlap the cutting path of the first lawn mower.

摘要： The invention comprises an improved lawn mowing machine with a forward mounted mower deck including a plurality of rotary cutters. The blades or cutters rotate in opposite direction on opposite sides of the deck to bring the grass clippings to a deck mounted central vacuum. The mower blades are driven by a belt drive to eliminate expensive drive shafts and gearboxes. Applicant's 45.degree. twist belt drive geometry provides increased life to the belt over prior art 90.degree. twist belt drive geometries.The mower deck includes novel side mower wings. A combined clutch and brake mechanism disengages the drive belt to the wing blade spindle and simultaneously brings the blade to a stop within one second when the wing is raised beyond its cutting range. The wing deck is attached to the mower central deck by a depressed hinge substantially close to the elevation of the mower blades. As the mower encounters uneven ground the separation of blade cutting paths is minimized in the movement of the wing blades relative to the central mower deck blades.
