A mobile, self-powered, horticultural processing unit capable of facilitating the processing of a large number of plants, is disclosed. In particular a modular unit with a multi-level configuration and a compact footprint capable of performing a variety of different horticultural operations is the subject of present embodiments. The unit may utilize a wheel and suspension assembly attached to a hydraulic lift and towing hardware which permits the unit to be towed as a trailer. The unit may comprise a plurality of conveying platforms which permit access by a forklift, as to allow many plants to be input and removed from the unit at once. The unit may assist in the fully or partially automated pruning, canning, fertilizing, treating, and spacing of plants potted in individual containers. Collectively, the cost and labor involved with growing and maintaining plants in the field may be greatly reduced.

A cutting blade applied to a reciprocating-type cutting device (1) including a pair of cutting blades (2, 3) that are reciprocated in a state of being superposed on each other to cut an object to be cut. The cutting blade includes: a base element (21); and a plurality of blade bodies (22) jutting from the perimeter of the base element (21), the plurality of blade bodies (22) each having a sliding surface (24) that slides over a mating blade body (32). At least some of the plurality of blade bodies (22) each have a high-hardness section (22A) formed in a part including at least both ends (24a, 24b) in a sliding direction of the sliding surface (24), the high-hardness section (22A) having hardness higher than the hardness of the other part. The thickness of the high-hardness section (22A) is set to 10 μm or more and 200 μm or less.

The present disclosure provides a transmission assembly and a garden tool. The transmission assembly is configured to connect a drive assembly and a garden work assembly. The transmission assembly comprises a casing and a first transmission component and a second transmission component accommodated in the casing; the first transmission component and the second transmission component are engaged with each other; the first transmission component comprises a first gear and a second gear engaged with each other; a gear shaft of the first gear is disposed at an angle with respect to a gear shaft of the second gear; and the second transmission component comprises a third gear able to rotate coaxially with the second gear and a fourth gear engaged with the third gear. With two levels of transmission components provided in the transmission assembly of the present disclosure, the output power of the garden tool can be controlled effectively, and the cost for using and producing the garden tool of the present disclosure are reduced while ensuring that the garden tool can be used normally.

A power saw system having an electric power saw in a varying angled engagement to a pole is provided. The pole is extendable to position the power saw elevated for cutting branches and the like. A remote control, actuated by a user, connects electric power to the saw to cause the saw blade to cut. A camera may be included to provide a remote user a view of the saw blade and areas proximal to it.

A lopper or lopper head attachment may include a primary gear, a secondary gear, a ratchet gear, an engagement flag, a dampened lag bolt, and a cutting blade. The secondary gear may be enmeshed with the primary gear. The secondary gear may define a lag groove radially offset form the secondary axis. The ratchet gear may be rotatable about a secondary axis separately from the secondary gear. The engagement flag may be rotatably mounted to secondary gear to move between an unengaged position and a engaged position. The dampened lag bolt may be slidably received within the lag groove to move relative to the secondary gear between a permissive position and a restrictive position. The cutting blade may be in mechanical communication with the ratchet gear to be pivoted thereby, in the engaged position of the engagement flag, to a closed position from an open position.
