  • Patent number: 6485036
    Abstract: A sulky for a self propelled, outdoor power equipment unit, such as a wide area mower or WAM, comprises independent left and right foot platforms to support a standing operator. A ground engaging caster wheel is carried on each foot platform to allow the foot platforms to roll over the ground during operation of the mower. The foot platforms are mounted to the mower by an axle with each foot platform being pivotally carried on the axle using a separate pivot hub. Thus, the foot platforms can pitch up and down separately from one another during operation of the mower over uneven terrain. Latches are provided for selectively holding the foot platforms in raised transport positions.

  • Patent number: 6454019
    Abstract: An agricultural implement includes a frame, a grow medium manipulation surface configured to manipulate and move a growing medium and at least one elastomeric torsion element coupled to the surface. The growing medium manipulation surface moves between a first growing medium engagement position in which the surface manipulates and moves the growing medium and a second growing medium non-engagement position. The elastomeric torsion element resiliently biases the surface towards the first growing medium engagement position. In one exemplary embodiment, the growing medium engagement surface comprises the surface of a furrow opening device on an agricultural implement. In one exemplary embodiment, the implement additionally includes an adjustment mechanism coupled to the elastomeric torsion element.

  • Patent number: 6453582
    Abstract: A snowplow apparatus as adapted to attach to a vehicle having a ball hitch assembly. The snowplow apparatus has a blade assembly connected to an elongated drawbar. A frictionally activated elevating mechanism is operatively connected to the drawbar and moves between a vertical and non-vertical orientation depending upon whether elevation of the blade or contact with the blade and the ground is desired, respectively. A further aspect relates to a lateral stabilization device associated with the opposite end of the drawbar, such stabilization device coming into contact with static members operatively associated with a hitch ball such that lateral movement of the drawbar is substantially precluded due to the contact between the stabilization members and the static elements.

  • Patent number: 6443079
    Abstract: An agricultural machine has a movable rack (10) having at least one main wheel (16, 18), a hitch (12) which is arranged on the rack (10), a reservoir container (14) which is carried by the rack (10) and/or the hitch (12), and an agricultural implement (20) which is attached to the rack (10) at the rear in the direction of travel and has a plurality of rear support wheels (28). The machine is developed to the effect that the at least one main wheel (16, 18) is positively steered as a function of the pulling direction of a traction force which is exerted on the hitch (12). Such a machine is particularly compact and maneuverable even when the reservoir container is large.

  • Publication number: 20020074139
    Abstract: The implement has a main frame supported at the rear by ground-engaging transport wheels and at the front by ground-engaging gauge wheels. A hitch is pivotally connected to the front end of the main frame so that the hitch and frame can flex relative to one another when the towing tractor experiences different terrain than the main frame. A self-leveling mechanism is normally disengaged when the implement is in its field operating position so that the hitch is free to float relative to the frame during terrain changes. However, when engaged, the self-leveling mechanism operates to maintain the main frame level as the transport wheels are lowered to raise the main frame into its transport position. A latch, remotely actuatable from the tractor seat, determines whether the implement is in its self-leveling mode or floating hitch mode.

  • Patent number: 6293352
    Abstract: An agricultural planter is provided with forwardly folding wing members that allow conversion of the planter from a laterally extending operating position to a compact transport position. To increase stability for the planter, the draw bar telescopes as the wing members are folded forwardly into the transport position. Brace members interconnect a forward portion of the draw bar and the wing members. As the wing members fold forwardly, the brace members are arranged to cause a rearward portion of the draw bar to extend rearwardly from the forward portion and effect the telescopic action in the draw bar. A draw bar hitch lock linkage is provided to keep the draw bar compacted when the wing members are in the operating position. A hitch lock actuator is tied into the hydraulic system for the movement of the wing members into the transport position to permit the telescopic action of the draw bar in concert with the forward folding of the wing members.

  • Publication number: 20010011595
    Abstract: A forwardly folding tillage implement carries a number of ground engaging tools on a tool gang frame disposed to the rear of a carrier frame. A rockshaft is disposed between the carrier frame and the tool gang frame and is movable between four rotated positions about two axes of rotation. A control mechanism controls the relative angular position of the rockshaft. A support mechanism is disposed rearwardly of the axes of rotation to support the rear of the tool gang frame above the ground in the field working position. An abutment member restrains the relative rotation between the rockshaft and the tool gang frame to fully support the tool gang frame on the rockshaft upon rotation of the rockshaft. A secondary hitch mechanism is also provide to couple a second implement behind the forwardly folding tillage implement.
