HARVESTER REEL HAVING SELF-ADJUSTING TINE BARS

A harvester reel for an agricultural harvester. The harvester reel includes a central rotatable shaft, and a plurality of reel tine bars extending widthwise across the reel and connected to the central rotatable shaft for rotation therewith. Each of the plurality of reel tine bars includes a biasing member for biasing the reel tine bar to rotate about its central longitudinal axis, and a plurality of tines. A cam assembly guides rotation of the plurality of reel tine bars. The cam assembly includes a primary cam for guiding rotation of the tine bars during rotation of the central rotatable shaft, and a moveable or stationary secondary cam. The moveable secondary cam pivots the tine bars about their longitudinal axes away from a cutterbar. Alternatively, a moveable diverter cooperates with the stationary secondary cam to pivot the reel tine bars about their longitudinal axes away from the cutterbar.

Draper head with securing action for a height-adjustable reel

A harvester is provided with a draper head that has a frame extending substantially across a working width of the draper head. Cutting elements are arranged at a front side of the draper head and connected to the frame. Conveying surfaces and conveying members transport cut crop from the cutting elements to a discharge location of the draper head. A reel extends transversely to a working direction of the draper head across the working width of the draper head. Reel support arms are pivotably supported on the frame and support the reel. A hydraulic adjusting drive is operatively connected to the reel support arms to pivot the reel support arms to carry out a height adjustment of the reel. A hydraulic circuit is operatively connected to the hydraulic adjusting drive and has a hydraulic valve that is able to lock the hydraulic circuit.

Pivoting safety stop for a ball-jointed cylinder

An actuator assembly for moving an implement attached to an agricultural vehicle. The actuator assembly includes an actuator comprising a longitudinal axis, a cylinder extending along the longitudinal axis, and a piston rod extending from the cylinder along the longitudinal axis and that is configured to be attached to the implement at a connection point. A safety stop is pivotably attached at the connection point and is movable between a deployed position where the safety stop is configured to block retraction of the actuator, and a retracted position where the safety stop is not configured to block retraction of the actuator. The safety stop is configured to rotate with respect to the actuator about a first rotational axis that is orthogonal to the longitudinal axis, as well as a second rotational axis that is orthogonal to both the longitudinal axis and the first rotational axis.

Float arm support

A float arm support system may include a float arm supporting an active member, the float arm being pivotable about a first axis, a skid shoe to bear against and follow local ground contours of the underlying terrain while supporting the active member of the float arm above the underlying terrain and a powered actuator. The skid shoe may be coupled to the float arm between the first axis and the active member. The powered actuator may be operably coupled to the skid shoe to vertically move the skid shoe to adjust a spacing at which the skid shoe supports the active member of the float arm relative to the underlying terrain.
