摘要： A self-propelled mower includes a frame and a mower housing mounted underbelly relative to the frame by a mounting assembly. The mounting assembly allows the mower housing to be disconnected from the frame and swung near the front of the housing from a mowing configuration to an access configuration as a front end of the mower is raised. The frame incudes a yoke that receives a nose of the housing, as the front of the mower is raised.

摘要： A foot pedal lift system is provided for the mower deck of a lawn or garden tractor. The foot pedal is pivotally mounted to the frame of the tractor and is linked to the linkage arms which suspend the mower deck from the frame. The pedal is movable between a depressed forward position to raise the mower deck to a transport position and a retracted rearward position to move the mower deck to a lower removal position. The pedal can be locked in the depressed or retracted positions by a latch pivotally mounted on the exterior of the tractor console. Engagement and disengagement of the latch with the foot pedal is controlled by a handle mounted on the console connected to the latch by an elongated connecting rod. Pulling upwardly on the handle locks the latch into engagement with the foot pedal in both the depressed and retracted positions. Pushing downwardly on the handle disengages the latch from the foot pedal so that the mower deck is free to move upwardly or downwardly.

摘要： A zero-turning-radius power lawn mower for operation by a standing-occupant includes first and second independently driven and controlled rear drive wheels mounted on separate drive axles. A riding platform for supporting the standing-occupant or operator is located between the first and second rear drive wheels. The rear drive wheels are independently driveable in both the forward and reverse directions at variable speeds so as to allow for substantially zero-radius-turning of the mower about a central turning point. The riding platform is positioned at this turning point so that the standing-occupant remains substantially unaffected by centrifugal force created during approximate zero-radius-turning of the mower thereby allowing the mower to take such turns at higher speeds. Such positioning of the platform also provides for improved maneuverability, reduces the likelihood that the platform will bottom out when the mower goes over bumps, and creates a safer mower less susceptible to tipping due to the resulting low center of gravity. The low center of gravity created by the position of the riding platform for the standing-operator also results in the mower having improved traction and being less likely to pop nullwheeliesnull upon acceleration.

摘要翻译： 用于由驻车人操作的零转弯半径功率割草机包括安装在单独驱动轴上的第一和第二独立驱动和受控的后驱动轮。 用于支撑站立或操作者的骑乘平台位于第一和第二后驱动轮之间。 后驱动轮可以以可变速度在前后方向上独立地驱动，从而允许割草机绕中心转折点基本上零半径转动。 骑乘平台位于该转折点处，使得站立人员基本上不受由割草机近似零半径转动期间产生的离心力的影响，从而允许割草机以更高的速度进行这种转弯。 平台的这种定位还提供了改进的机动性，减少了当割草机越过颠簸时平台将底部的可能性，并且由于所产生的低重心而产生较不易于倾翻的更安全的割草机。 由立式操作员的骑乘平台的位置产生的低重心也导致割草机具有改进的牵引力，并且在加速时不太可能弹出“轮椅”。

摘要： A yard vacuum unit includes a deck including upper and lower housing members that form a discharge outlet and a nozzle operatively connected to the deck. An engine is mounted to the deck and includes a drive shaft. An impeller assembly is used to draw yard debris in through the nozzle and out through the discharge outlet and is positioned between the upper and lower housing members. The impeller assembly includes an impeller plate, a hub fixedly connected to the impeller plate, and a plurality of fan blades each having first and second ends and first and second sides. Each fan blade first end is fixedly connected to the hub all along the first end and each fan blade first side is fixedly connected to the impeller plate all along the first side. In this way, a continuous airtight seal is formed along the entire first end of each fan blade with the hub and along the entire first side with the impeller plate. Each second end extends to the outer periphery of the impeller plate.

摘要： An auxiliary edge trimmer apparatus is attached to a lawnmower and includes a flywheel drive wheel portion connected to the lawnmower drive shaft. An attachment assembly is connected onto portions of the lower housing wall of the blade housing of the lawnmower. A trimmer assembly is attached to the attachment assembly and includes a bearing portion connected to the attachment assembly, a rotatable shaft assembly received by the bearing portion, a driven wheel connected to a proximal end of the rotatable shaft assembly, and a trimmer blade connected to a distal end of the rotatable shaft assembly. In accordance with an alternatively preferred embodiment of the invention, a manually actuatable control cable is attached through suitable means to the drive shaft supported on the lawnmower housing between the drive wheel and the auxiliary trimmer apparatus to control engagement and disengagement thereof. Additionally, angular orientation adjustment means for the auxiliary trimmer assembly relative to the main rotation shaft axis of the lawnmower are provided to assure precise control of the width of cut afforded by the auxiliary trimmer apparatus.

摘要： Jacking apparatus for use with ground maintenance vehicles and methods of using such apparatus are provided. In general, the jacking apparatus includes a jacking member which may pivotally couple to the frame of the vehicle. The jacking member is preferably positionable in a stored position, a jacking position, or a jacked position wherein the stored and jacking positions correspond to the vehicle being in an operating configuration while the jacked position corresponds to the vehicle being in an elevated, maintenance configuration. During operation, the driving power of the vehicle may be used to propel the vehicle up and onto the jacking member, thereby elevating a first portion of the vehicle relative to a second portion. Preferably, the apparatus further includes a latching device to permit latching of the jacking member in both the stored position and the jacked position.

摘要： A tree cutting attachment for a skid loader or other types of self-propelled work vehicles to be used at construction and landscaping sites. The device is used to cut down brush and trees of up to about 12 inches in diameter. The tree cutting attachment is made up of a motor driven rotor assembly which is journaled within a frame of the attachment. The rotor assembly comprises a cage-like mounting system having pockets in which tempered steel blades, approximately ten inches in width are bolted in a side-by-side relation. Two rows of blades are mounted 180 degrees apart proximate the periphery of a rotor comprised of a series of parallel, generally circular plates that are welded to longitudinally extending rods. The knife blade elements are bolted to the blade holders with the non-sharpened end of the blade elements abutting a flat steel bar that forms part of the cage. In a second embodiment, the frame comprises a stationary portion adapted to be rigidly affixed to the hitch of the work vehicle and a movable portion that can be pivoted relative to the stationary portion. Because the movable portion is arranged to pivot about the powered drive shafts, tiling of the movable portion to bring the cutting blade rotor into engagement with a tree to be felled does not alter drive belt tension.

摘要： An upper hood and a blower housing form an air induction cavity in the side of the mower hood, which draws the ambient air into the air intake and from there into the engine. Two shield members on the blower housing prevent the ambient air from mixing with the hot air of the engine. A method of air induction is also disclosed, including the steps of forming an air induction cavity by connecting the upper hood to the housing, having the lower lip of the air induction cavity lower than the air intake of the blower housing, channeling the air into the air intake via channels on the blower housing, and preventing the hot air of the engine from mixing with the ambient air drawn through the air induction cavity.
