A riding lawn mower includes a frame, a mowing device mounted to the bottom of the frame, a functional unit attached to the front of the frame, and a motor group together with a power supply mounted to the frame. The riding lawn mower also comprises a connecting device connecting the frame and the functional unit. The connecting device comprises a first connector attached on the front of the frame, a second connector attached to the functional unit, and a third connector adapted for fixedly connecting the first connector and the second connector, the first connector and the second connector respectively defining through-holes thereon, the third connector extending through the through-holes of the first and the second connectors to fixedly connect the first and the second connectors.

A header for an agricultural vehicle includes: a header frame; a flexible cutter supported by the header frame and including a plurality of cutting edges; a reel including a plurality of reel sections movably supported by the header frame, each of the reel sections including a plurality of tines and being independently movable from the other reel sections; and at least one rigid link connecting the flexible cutter to one of the reel sections, the at least one rigid link being configured to transmit flexing forces acting on the flexible cutter to the connected one reel section such that a substantially constant separation is maintained between the flexible cutter and the connected one reel section.

A dual-cam linkage system controls the orientation of tines on a reel of a crop harvesting header. The dual-cam linkage system includes a stationary, substantially circular first cam track that has a rotational center that is offset from the rotational axis of the reel. A second cam track is located in a support plate on which a tine-supporting member is mounted. The dual-cam linkage system also includes a pivoting linkage having a crank, an arm. The crank has a first end fixedly attached to the tine-supporting member. The arm has an outer end attached to a second end of the crank. The first cam follower is attached at an inner end of the arm and engages the first cam track. The second cam follower is attached to the arm at a position between the first cam follower and the crank and engages the second cam track.

An agricultural vehicle including a chassis and a header carried by the chassis and including a cutter mechanism. The header is adjustable in a vertical direction. The agricultural vehicle also includes a header actuator connected to the header and configured to adjust the header in the vertical direction, and a controller coupled to the header actuator. The controller is configured for receiving an input command for controlling an operation of the header actuator to achieve a lifting height, operating the header actuator in conformance with the input command, and terminating the operating of the header actuator.
