Variable displacement motor control system
A hydraulically powered implement is designed for use in connection with a tractor that has a hydraulic pump that supplies pressurized hydraulic fluid to the implement. The implement includes a variable displacement hydraulic motor, an operative element driven by the hydraulic motor, a speed sensor configured to measure the rotational speed of the operative element and output a speed signal representative of the measured speed, a shift module that adjusts the displacement of the hydraulic motor in response to a shift command signal, and a controller. The controller sends the shift command signal to the shift module in response to speed signal output by the speed sensor.
Mulcher with shiftable chopping blade rotors
An apparatus (mulcher) for keeping down groundcover between parallel rows of plants, especially rows of wine grape or fruit plants, with two chopping blade rotors rotating in one and the same plane, each around an axis perpendicular to the ground. The distance between the rotational axes is adjustable in a direction perpendicular to the plant rows even though the rotational areas of the chopping blade rotors may overlap. A separate electric motor is assigned to each of the chopping blade rotors, and devices are provided to control the electric motor so that that collisions between the chopping blade rotors are avoided.
LAWN MOWER WITH IMPROVED CUTTING STRUCTURE
In certain example embodiments of this invention, the lawn mower includes one or more of: (a) cutter deck baffle teeth for improving cutting performance; (b) a trim divider edge portion of the cutter deck for improving cutting performance; (c) a trim vacuum structure portion of the cutter deck for improving cutting performance; and/or (d) a center vacuum structure portion of the cutter deck for improving cutting performance.
MOW DECK AND BAGGING SYSTEM FOR HIGH EFFICIENCY WALK-BEHIND MOWING APPARATUS
A high efficiency turf maintenance apparatus having low power consumption and good cutting performance is presented herein. A blade configuration is disclosed to provide lift and to propel turf clippings from within a mow deck through a discharge opening therein. A discharge body can receive turf clippings at an input and direct the turf clippings to an output. A bagging apparatus can be coupled to the discharge body output for a bagging mode, a side-rear diverter can be coupled to the discharge body output for a discharge mode, and a mulching plug can cover the discharge body output for a mulching mode.
COMBINED MULCHER AND CHIPPER ATTACHMENT
A mulching and chipping attachment includes a deck having a top plate. A cutting disk is attached to the deck. The top plate includes an opening that exposes a portion of the cutting disk. A guide chute is attached to the deck, and is disposed over the opening. The guide chute includes a feed system. The feed system includes a first roller, and a reactionary member operable to react against the first roller to secure a log therebetween. The first roller and the reactionary member cooperate together to grasp and controllably feed the log through the opening. The first roller or the reactionary member may be moveable relative to the other, to adjust a throat distance therebetween. An anvil may be disposed at a rearward edge of the opening, and extend downward to define a chip cutting height between the anvil and the cutting disk.
LAWNMOWER MULCH PLUG RAMPS TO IMPROVE MULCHING PERFORMANCE
A lawnmower with a mulch plug with a plurality ramps for deflecting lawn clippings out of a cutting deck with more than one depth planes. The mulch plug is configured to attach to the lawnmower by one or more attachment points to block a collector opening of the lawnmower. The plurality of ramps comprises a first ramp and a second ramp on the lower plane of the cutting deck extending downward from the mulch plug. The second ramp is positioned further in the cutting rotation of the lawnmower on a trailing edge of the mulch plug. The secure attachment of the mulch plug with a plurality of ramps provides a more even distribution of grass clippings.
LAWNMOWER MULCH PLUG FIXING METHOD
The present disclosure is directed to a mulch plug configured to attach to a lawnmower by one or more attachment points, including a snap-fit attachment point. The snap-fit provides a more secure attachment to the lawnmower than attachment mechanisms on existing mulch plugs, in turn providing more even distribution of mulch and less clogging and locking of mower wheels.
MULCH SPREADER
The mulch spreader is a piece of lawn maintenance equipment that comprises a rotating mulch dispensing chute and a compressed air mulch loosening feature. The mulch spreader is wheeled and has a hopper that is suspended above the ground on wheel supports. A rotating dispenser chute is situated below the hopper and the rotating action of the chute spreads mulch over a wider area than a simply drop chute would cover. The motor that causes the chute rotation is powered by a rechargeable battery contained within the mulch spreader. The same rechargeable battery also powers an air compressor. Air from the air compressor may be used to loosen mulch in the hopper and to expel mulch from the hopper via an optional external hose.
Lawn mower with improved cutting structure
In certain example embodiments of this invention, the lawn mower includes one or more of: (a) cutter deck baffle teeth for improving cutting performance; (b) a trim divider edge portion of the cutter deck for improving cutting performance; (c) a trim vacuum structure portion of the cutter deck for improving cutting performance; and/or (d) a center vacuum structure portion of the cutter deck for improving cutting performance.
Mulching mower unit
A mulching mower unit includes a mower deck, a rotary shaft, a blade, a shroud, and a deflector plate. The shroud has a circumferential wall including a rotational trajectory of the blade, and extends downward from a bottom surface of the mower deck to an area adjacent to the blade. The deflector plate is provided above the blade and radially outward of the rotary shaft in a running direction in an inner space of the shroud. The deflector plate includes a main body having an inner edge facing the rotary shaft and an outer edge spaced apart from the inner edge radially outward of the rotary shaft. The outer edge is positioned closer to the ground than the inner edge.
