And Cutter Adjustable Relative To Ground Patents (Class 56/17.1)
  • Publication number: 20100326032
    Abstract: An electrically powered two wheel mowing, trimming and edging apparatus is disclosed. A rotating cutting head is cantilevered in front of the wheels, with a battery positioned behind the wheels to act as a counterweight to the cutting head. A caster below the battery allows easy maneuverability and permits trimming in corners. The cutting head contains both metal cutting blades and filament line, and the operator selects which cutting tool he wants based on the type of foliage to be cut. The cutting head easily rotates from the horizontal to the vertical, allowing the apparatus to be used as an edge trimmer.

  • Patent number: 7600363
    Abstract: A rotary cutting deck is suspended from the frame of a lawn mower to hang beneath the frame of the mower between the front and rear ground engaging wheels of the mower. A single front pull arm is pinned by a pivot pin to the front of the cutting deck. This pivot pin can be easily released and pulled by removing a single hairclip pin or cotter pin. The rear of the cutting deck is hung by two downwardly facing suspension hooks onto the cross rod of a pivotal hanger. After the front pull arm is disconnected from the front of the cutting deck, the operator lifts up the rear of the cutting deck to unhook the suspension hooks, pulls the cutting deck slightly rearwardly, and then lowers the cutting deck to the ground to allow the cutting deck to be slid out from underneath the mower after also removing any deck drive belt or similar cutting blade drive system. This can be easily and quickly done.

  • Patent number: 7107745
    Abstract: A trimmer wheeled accessory for a gas or electric powered line trimmer used to support the distal end of the trimmer pole during operation. The accessory includes an extension arm that is longitudinally aligned with the trimmer's main pole and selectively attached thereto via a first clamp. The distal end of the extension arm extends from the trimmer head. Attached to the distal end of the extension arm is a wheel assembly that supports the trimmer head at a constant elevation when cutting grass or weeds. The extension arm is sufficient in length so that the wheel accessory is located in front of the trimmer head. The extension arm may be rotated around the trimmer's main pole so that the wheel assembly may be used to support the trimmer head in both a horizontal or vertical alignment.

  • Patent number: 7003937
    Abstract: An adjustment pin for making precision adjustments to the cutting deck height of a lawn mower having a cutting deck height adjustment mechanism that employs a lever, a lever support bracket having lever set holes. The adjustment pin has an elongated stem of a uniform diameter. Disposed along the stem of the pin is a plurality of pin adjustment portions. These adjustment portions each have a successively reduced diameter with respect to the pin stem diameter. Adjustments to the cutting deck height are accomplished by inserting the pin in a desired lever support bracket set hole and positioning the lever against a desired adjustment portion of the pin stem. The user may make precision adjustments of the deck height depending upon his selection of the lever set hole and the choice adjustment portion of the pin stem on which to set the lever.

  • Patent number: 6837032
    Abstract: A lockable lift assembly for controlling the height of a mower cutting deck is provided. The assembly includes a pedal actuated system including a rockshaft extending the width of the mower frame and having plates on which the deck is carried as a change in height is either performed or maintained. Intermediate these extensions is a toothed plate which cooperates with a handle operated latching system to permit a user to fixedly control the height of the cutting deck. Joint use of the pedal and latching system enables placement of the deck in a position wherein the deck is raised above the highest heighth of cut for travel across the ground or, alternatively, in a removal position in which the deck may be securely and quickly detached from the mower.

  • Publication number: 20040216438
    Abstract: A system adjusts the height-of-cut of a cutting reel unit. The system includes a cutting reel; a first frame supported on at least one support element that is supported on, and is movable along, the ground; and a second frame supporting the cutting reel. The system further includes an actuator that has a first portion connected to the first frame and a second portion connected to the second frame, wherein a distance between the first and second portions is adjustable. The actuator includes a motive mechanism that is activated to adjust the distance. The system can include at least one strut pivotally connected to the first frame and pivotally connected to the second frame on a second side of the second frame opposite to the first side. The strut extends between the first frame and the second frame. The strut defines the rotation of the second frame with respect to the first frame as the relative elevation of the second frame is adjusted with respect to the first frame.
