A track-type moving device having one or more track mechanisms. The track mechanism may include a guide wheel, a driving wheel, a track, and/or a tensioning mechanism. The tensioning mechanism may include an adjusting member and/or an elastic member. The elastic member may provide a driving force that enables the adjusting member to move.

An attachment of a harvesting head of a combine is disclosed. The attachment includes a main body and a flange fixedly connected to the main body. The flange is connected to the main body at an angle and the flange has at least one mounting aperture. The flange is configured to be attached to the harvesting head of a combine by the at least one mounting aperture. When the flange is attached to the harvesting head of the combine and the combine is performing a harvesting operation, a furthest portion of the main body away from the flange is positioned above a lowest portion of the harvesting head from a ground surface.

A trimmer mower rotor (100), formed by a receptacle (105) on which at least one plastic thread (103) is wound, wherein the receptacle is rotatably accommodated in a housing (101) and the receptacle (105) and the housing are rotatable about a single axis, wherein the housing (101) has at least one opening through which the at least one plastic thread (103) is passed to the outside. The receptacle (105) and the housing having the at least one opening rotate at different speeds.

A land roller implement for chopping vegetation on the ground has one or more rollers including a drum body with mounting flanges protruding radially from the drum body onto which chopping blades can be fastened. The mounting flanges are fixed to the drum body with front weld beads that are spaced apart along the leading face of the mounting flanges. The blades are notched along the inner end to define recessed portions aligned with and receiving the front weld beads therein such that protruding portions at the inner end of the blades between the recessed portions are able to abut against the peripheral surface of the drum body without interference by the front weld beads. The bolts fastening the blades to the mounting flanges are thus isolated from shear forces by the abutting protruding portions while the mounting flanges remain secured against folding backward due to the presence of the front weld beads within the recessed portions.

A combination of a marsh buggy is coupled with a modified skid steer. The skid steer has a frame, and hydraulic lines for attaching to hydraulic driven motors for driving a track or wheeled drive system. The skid steer further having an engine and a hydraulic system, including a pump and hydraulic tank, and valves; an operator's cab positioned on the frame, said operator's cab further comprising a set of hydraulic controls connectable to the hydraulic system for controlling the drive system and a hydraulically driven lift system, including two booms, each boom comprising a first arm and a second arm, the first arm being pivotably mounted to the frame, the second arm being telescopically coupled to the first arm by a hydraulic cylinder controllable from the operator's cab. The marsh buggy includes a first and a second floatable pontoons, the two pontoons coupled together in a parallel but offset relationship. Each pontoon has an endless track including a chain and treads coupled around the periphery of each respective pontoon, and a series of sprockets coupled to the chain on each pontoon; each sprocket connected to a hydraulic motor. The marsh buggy further has hydraulic motors and drive sprockets coupled to the hydraulic system for driving the endless track. The skid steer is mounted on the marsh buggy, between the two pontoons, and the hydraulic motors of the marsh buggy are operationally coupled to said hydraulic system of said skid steer so that said hydraulic controls in said cab are operationally connected to said hydraulic motors to control the drive system on the marsh buggy.

A brush cutter rotor comprising cutting tooth assemblies sequentially arranged along a longitudinal axis of the brush cutter rotor, and azimuthally offset to make up intertwined spirals of cutting tooth assemblies. The cutting tooth assemblies of immediately adjacent tracks are arranged to provide for a longitudinal gap in-between, and separating blades are provided within said longitudinal gap on each side of each track comprising one of the cutting tooth assemblies. They form a comb to separate incoming material to a center of the corresponding one of the cutting teeth and away from side edges thereof. The front space before the central portion of cutting teeth is thereby free, exempt from a protective guard. A wear plate can be used in the holding base of the cutting tooth assemblies under each cutting tooth.

A cutting assembly is mounted on the lawn mower to perform cutting work. The cutting assembly includes a cutting deck and at least two cutting element groups disposed at different heights of the cutting deck. Each cutting element group includes at least one cutting element. The cutting deck responds to driving of the lawn mower to rotate and drive the cutting elements to rotate, to form at least two cutting trajectories at the different heights of the cutting deck. In the cutting assembly and the lawn mower, the at least two cutting element groups are disposed at the different heights of the cutting deck, to enable the cutting assembly to be driven by an electric tool to form the at least two cutting trajectories.
