A stand-on mower may have a deck with at least one deck wing. The mower may include a stand-on operator platform, a rear wheel axis positioned forward of the stand-on operator platform, a main deck having main deck blades with rotational axes positioned forward of the rear wheel axis, one or more deck wings, and front wheels positioned forward of the rotational axes of the main deck blades.

Stand-on mower with winged deck

Aspects hereof relate to a stand-on mower having a deck with at least one deck wing. The mower may include a stand-on operator platform, a rear wheel axis positioned forward of the stand-on operator platform, a main deck having main deck blades with rotational axes positioned forward of the rear wheel axis, one or more deck wings, and front wheels positioned forward of the rotational axes of the main deck blades.

A multi-blade mower deck having a center right and left blade chambers, which are partially connected to each other, each blade chamber including a rotary mounted cutting blade with lifting sails thereon for rotating and lifting the air into each blade chamber, a front skirt defining portions of said blade chamber; a continuous rear skirt wrapping around rear portions of each of said blade chambers; and a fan chamber positioned above the cutting deck and concentrically aligned over the center blade chamber and having an opening into the center fan chamber including concentrically mounted impeller blades for driving air and clipping from the fan chamber through a exhaust passage positioned over the cutting deck.

Rotary mower up-flow cutting deck

The invention is a self-propelled drivewheel steering power mower which can be operated in a standing or sitting position, including a pair of variable flow hydrostatic pumps with tiltable swash plates, each of which drives one of a pair of drivewheels. A vertically mounted steering shaft is rotatably supported on the mower for rotation about an axis concentric with said shaft; and a T-shaped steering handle bar is rotatably journaled to the end of said steering shaft for twisting about an axis concentric with said handle bar. A first pair of connecting rods connects the steering shaft to the swash plate of each variable flow pump whereby rotation of the steering shaft in one direction will increase the flow rate to one of the variable flow pumps while decreasing the flow rate proportionately to the other variable flow pump to effect steering right or left; and a second connecting rod connects the steering handle bar to the first pair of connecting rods whereby twisting of the handle bar in one direction increases the flow rate proportionally to both variable flow pumps while twisting in the opposite direction decreases the flow rate proportionally to both variable flow pumps to effect acceleration and deceleration of the mower.

Single lever drivewheel steering power lawn mower

A four-wheel mobile vehicle including provision for controlling the steering position of each of the four (4) wheels so that every wheel's rolling axis will intersect at a common point around which the vehicle will turn. The control is provided by a pair of cables, one on each side of the vehicle which interconnect a pair of front and back wheels to turn each pair through similar angles in the opposite direction. The variance in angular turning between wheels on opposite sides of the vehicle is caused by wrapping the cables on each side around an identical cam pulley, one on each side, both of which are mounted on a common shaft so that their angular rotation is always identical while their winding radius is changing. The pair of cables are separately driven at different rates by a pair of double-acting hydraulic cylinders connected in parallel to a conventional power steering unit whereby the winding in and paying-out of the cable on the cam pulleys at different radiuses causes the wheels on opposite sides to turn at different rates.

Four-wheel coordinated steering multi-purpose tractor

A rotary type lawn mower and mulcher for mounting a tractor characterized by an open-bottom housing with a discharge opening having two or more cutting blades rotatably journaled in the housing and moving in a common cutting plane, a plurality of high speed mulching blades mounted on a single spindle at various heights positioned in the downstream paths of the cutting blades, the individual cutting blades having a longitudinal cutting edge therealong with lateral corrugations throughout the cutting length thereby increasing the cutting plane depth of each blade whereby the vertical height within the housing above the cutting blades is substantially filled with the cutting planes of the mulching blades whereby the grass clippings from the cutting blades are finely cut and discharged at increased velocities through a discharge opening and a deflection chute positioned downstream thereof with a variable height dam extending into the discharge path of the mulching blades whereby the finely-cut clippings are deflected to achieve an even dispersal pattern of clippings across the angular path of the discharge chute.
