Abstract: An edger-trencher is described for landscaping procedures. Instead of the usual jolting an operator receives when using traditional power assisted edger-trencher devices, in the instant invention a pivotable swing arm with cutting blade attached at one end pivots upwards and away from the soil containing an obstruction. The cutting blade then falls back rapidly and repeatedly under the influence of gravity, causing a series of pick like actions on the soil obstruction until it is overcome and normal edging or trenching resumes. The pivotable swing arm-cutting blade combination is suitable for mounting on stand-alone gasoline powered, belt-driven edger-trenchers. Alternatively, this stand-alone unit can be modified to have a quick connection to a similarly modified commercial or residential mower of the rider or walk behind type.

Abstract: There is disclosed an improved lawnmowing and edging apparatus wherein a generally conventional gasoline powered push mower or walk-behind mower is provided with an edger mounted on the front of the deck of the mower slightly outside of the track of one of the front wheels, the edger having a high speed rotating blade which lies in a vertical plane and which can be raised to an inoperative position or lowered to an operative position. The edger is provided with a very simple belt and pulley drive which causes the edger to be powered only in its lowered position and which derives its motive power from a power-take-off extending outward from the lawnmower engine substantially at right angles to the direction of travel of the mower. The power-take-off shaft is thereby substantially parallel to the shaft of the edger and a simple trouble free and safe power drive mechanism can be provided for the edger.

Abstract: With a limited separating spacing immediately upstream of a mowing implement rotating in a horizontal plane, a lawnmower has an upward extraction implement rotating in the same direction as the advance direction about a horizontal transverse axis and which is located in a common casing, but in a separate casing chamber. The upward extraction implement is disengagingly driven by means of a gear by the drive motor of the mowing implement and is essentially located between the front wheels, which are vertically adjustable for the joint setting of the working height of the two implements. Thus, it is possible to in each case separately and also jointly and simultaneously work with the two implements, so that numerous use possibilities exist.

Abstract: A gardening utility machine having a counter-rotation twin shaft system can perform multiple types of work required for gardening (tilling, soil removal, weeding, raking and shredding of leaves), snow/ice removal and for power de-thatching and mowing of lawn grass. This can be done by exchanging attachments on the counter-rotating twin shafts: if tines are installed on the twin shafts, soil tilling, weeding can be done; if auger blades with or without digging bits are in place instead, the machine can simultaneously till and remove soil or can remove ice/snow, or rake and shred leaves; if the front shaft is installed with a spiked roller and the rear shaft, a shearing reel, then the machine can power de-thatch and mow grass at the same time, and additional grass clipping mulching ability can be performed if a fan blower equipped with a mulching fan blade and a retractable bedknife is in place.

Abstract: A power lawn mower is provided with a trimmer attachment pivotally attached to the mower deck and positioned adjacent a side edge of the deck to trim those areas not accessible to the mower blade. When a fixed obstacle such as a fencepost or tree is encountered, the attachment is rotated on a pivotal support arm against the force of a spring to a position adjacent the rear edge of the mower deck. When the obstacle has been passed, the force of the spring returns the trimmer to the side edge of the mower deck. The trimmer attachment is operated by a drive belt driven from the lawn mower engine and the trimmer attachment support arm includes a pair of overlapping telescoping members and a spring contained in one of the telescoping members to apply an outward force on the other telescoping member resulting in a positive tension being applied to the drive belt. The trimmer attachment may be retracted to the rear edge of the mower deck by operation of a lever mechanism and a link attached to the support arm.

Abstract: An improved lawn edger encludes an edging disk mounted for straight line adjustment, on the wheel axle of a lawn mower, between stowed and operative positions. One-handed operation moves the edger between these positions and, additionally, totally removes the edger for close-in mowing. The operating handle extends above the mower deck for ease of operation, while the apparatus minimizes undue tortional forces on the wheel axle.

Abstract: The present disclosure is directed to a mower blade-weed cutting flail assembly wherein the mower blade and the flail cutting line (cord) always rotate in opposite directions with the cutting line always rotating faster than the mower blade so that the two never meet, viz., the mower blade cannot cut the line and the line cannot damage the blade. Attached to the upper interior portion of the mower deck adjacent one end portion thereof is the upper flange portion of the return spring and support whose bottom end supports the bottom portion of the main flail housing at a position near the flail main housing stub shaft extension arm. This secondary return spring and support supports the flail main housing (for the cord trimming unit), keeps the driven disc of the line cutter away from the mower disc drive unless and until the operating handle is engaged.

Abstract: A motorized lawn mowing machine supported on wheels has a generally horizontal deck with a spindle mounted grass cutter blade below the deck which is rotatable in a generally horizontal cutting plane to cut grass as the machine moves in a forward path of travel.

Mounted on the deck for swinging movement between an extended operative position in which it extends forwardly and sidewisely angularly from said deck and a vertically raised inboard inoperative position is an auxiliary support having a vertically disposed spindle near its front end with a second pulley thereon. A rotary trimmer disc with flailing cords is mounted on the spindle to rotate in a horizontal plane.

Abstract: A pair of cutter bar-type mowers are rearwardly and laterally offset on a mower frame having steerable wheels for moving the mower between a cutting position offset from the tractor and a transport position directly behind the tractor. A spring-assisted power cylinder raises and lowers the cutting bar from a ground-engaging cutting position to a position with the cutter bar raised off the ground and then to a position with the cutter bar extending vertically for transport. The spring functions only to assist in raising the cutter bar off the ground by pivoting a frame arm and the pivoting of the cutter bar to the vertical position is by the power cylinder only.
