摘要： A walk aerator comprises a frame supported by a plurality of ground engaging wheels, the frame carrying a coring head having a plurality of side-by-side tine assemblies. The wheels define a wheelbase which is substantially equal to or less than the width of a coring swath and the wheels are located in advance of the coring head to keep the wheels from passing over the holes or soil cores left in any preceding coring swathes formed by the aerator. The vertical position of the coring head is adjustable up and down as the ground contour changes to keep hole depth substantially constant. The tine assemblies are reciprocated by a single crankshaft driven by a single pulley, the crankshaft being assembled from multiple crank arms that are splined and bolted together. Sealed bearings connect drive arms that drive the tine assemblies to the crankshaft. The crankshaft can be disassembled to allow the sealed drive arm bearings to be replaced. Integral core deflectors are used on the drive arms. A connecting link extending across each drive arm is used to connect each drive arm to the coring head to decrease the coring head depth.

摘要： A rotary mower (10) including a front deck assembly (18) and a pair of wing decks (20). Each wing deck (20) is supported by a lift arm assembly including a main lift arm (26) and a lift arm extension (32). A pivot joint (30) exists between lift arms (26) and (32) so that when deck (20) is raised from its cutting position to its transport position it is also caused to rotate so that mower (10) maintains a relatively low profile even when decks (20) are in their transport position. Mower (10) also preferably includes a pair of breakaway assemblies (48) which allow wing decks (20) to "break away" in the event they strike an immovable object. Finally, a preferred mower (10) includes resilient bushing assemblies (38) between the wing deck lift arm assemblies and the wing deck housings (24) to minimize vibration and noise and provide some floating of the decks (20).

摘要： A riding mower (2) includes a cutting unit (6) suspended from a traction unit (4). Cutting unit (6) is suspended from a forwardly extending frame (8) by four suspension units (40-43). Each suspension unit includes an upwardly opening saddle member (44) in which a pin (51) carried on cutting unit (6) is received. At least some of the pins (51) are longitudinally constrained in the saddle members (44) to longitudinally couple cutting unit (6) to frame (8). This allows cutting unit (6) to move upwardly relative to frame (8) at each of the suspension units to allow the cutting unit (6) to tilt or float relative to frame (8).

摘要： A foot pedal is mounted on a control lever operatively connected to a hydrostatic transmission mechanism for a vehicle, for controlling forward and rearward movement of the vehicle. A damping member, operatively associated with the control lever, frictionally engages the pedal to restrain movement of the pedal and control lever, which movement may be caused by heavy vibration of the vehicle during travel over uneven terrain.

摘要： A tine holder for holding a plurality of aerator tines has a plurality of substantially vertical, tapered bores. A tapered collar is adapted to be received in each bore with the collar being split so that the collar contracts as the collar is slid into the bore. The upper end of an aerator tine is inserted into each collar before the collar is inserted into the bore such that the contraction of the collar as the collar is thereafter slid into the bore will suffice to tightly grip and hold each tine in the tine holder. A tool is provided for providing enough leverage on the collar to slide the collar over final portions of its movement as the collar slides into the bore during tine installation or to slide the collar over beginning portions of its movement as the collar slides out of the bore during tine removal.

摘要： A walk aerator comprises a frame supported by a plurality of ground engaging wheels, the frame carrying a coring head having a plurality of side-by-side tine assemblies. The wheels define a wheelbase which is substantially equal to or less than the width of a coring swath and the wheels are located in advance of the coring head to keep the wheels from passing over the holes or soil cores left in any preceding coring swathes formed by the aerator. The vertical position of the coring head is adjustable up and down as the ground contour changes to keep hole depth substantially constant. The tine assemblies are reciprocated by a single crankshaft driven by a single pulley, the crankshaft being assembled from multiple crank arms that are splined and bolted together. Sealed bearings connect drive arms that drive the tine assemblies to the crankshaft. The crankshaft can be disassembled to allow the sealed drive arm bearings to be replaced. Integral core deflectors are used on the drive arms. A connecting link extending across each drive arm is used to connect each drive arm to the coring head to decrease the coring head depth.

摘要： A triplex trim mower (100) including a vehicle (102) having two front drive wheels (104) and one rear steerable wheel (106). Mounted generally forward of the front wheels (104) are two reel-type cutting units (108a) laterally offset about the longitudinal axis (110) of the vehicle (102). Mounted between the front and rear wheels and substantially centered between the forward cutting units (108a) is a rear reel-type cutting unit (108b). A lateral support frame (137) is incorporated into the main frame of traction vehicle (102). The cutting units (108) are supported by a lateral carrier frame (144) which is slidably engaged to lateral support frame (137) such that carrier frame (144) can move laterally relative to support frame (137). A hydraulic cylinder (158) permits carrier frame (144) to be laterally displaced under operator command. Second and third hydraulic cylinders (131) permit cutting units (108) to be moved between a transport position and an operating position. A single joystick (118) permits the operator to control all aspects of cutting unit position including transport or operating position and lateral offset position.

摘要： A leak detector apparatus 10 is disclosed which measures changes in fluid level in a tube 54 substantially located within a reservoir 29 of hydraulic fluid. The tube 54 has a first end which is open to the atmosphere and a second end which is submerged in the hydraulic fluid. The reservoir 29 is selectively sealed, therefore changes in the volume of the fluid within the reservoir 29 cause the fluid level within the tube 54 to change in accordance with the principles of a manometer. A measuring device is utilized to determine the level of the fluid within the tube 54, wherein the measurement device can include a float 22 having a magnet 23 located thereon interacting with a linear array of Hall effect sensors 24. A controllable venting valve 28 is provided through the reservoir 29 to equalize the pressure within the tank with the external ambient pressure. The opening and closing of the venting valve 28 is controlled by an electronic controller device 30 that uses float position and hydraulic fluid temperature as inputs, among others. Accordingly, the float position can be reset within the tube to extend the range, thereby creating a virtual column.
