A pivot pin assembly for a tree shaker pivotally attaches the clamping arm to the stationary arm. Each end of the cylindrical pivot pin extends outside of a cylindrical bore of the clamping arm. A longitudinal load member extends through an aperture in the stationary arm and into an aperture in the cylindrical pivot pin. An axial load may be applied to the longitudinal load member which compresses a plate of the stationary arm against the cylindrical pivot pin, but without compressing the stationary arm against the clamping arm. This configuration allows substantial torque to be applied to the longitudinal load member, which reduces play between the stationary arm and the clamping arm without inhibiting the free rotation of the clamping arm. Application of this torque eliminates radial and vibratory movement in the shaker head, which otherwise cause damage to the components of the shaker head.

The above is a description of a self-propelled tree fruit picking machine, of the type which includes a vibrator device which acts on the trunk of a tree detected by a probe device, including two side frames joined by a transverse gantries device, equipped with pulling devices to move the fruit towards peeling devices, and from these towards hoppers, in which each gantry includes four successively articulated segments, with anchoring devices between adjacent segments, which are extractable to fold the machine by the closing together of both side frames via the action of cylinders to a minimum width, with the machine equipped with a control cabin which can be moved inwards to the position of minimum width, and with the transport wheels connected to suspension devices adjustable in height via cylinders.

A handheld work apparatus having an electric motor and a drive circuit for the electric motor. The rotation movement of the motor is converted into an oscillating movement of the work tool via a gear mechanism. The motor is situated in a circuit including at least the motor and a switch for operating the motor. To reduce wear of the gear mechanism, a control unit for operating the motor in one of two directions of rotation is provided. The control unit independently determines a selected direction of rotation for a next operating cycle as a function of a control variable. When the motor is started, the motor is started by the control unit in the direction of rotation which is associated with a value of the control variable. The control variable changes before the motor is restarted for a following operating cycle.

In a shaker head for a tree shaker, a hydraulically actuated ram is mounted between the clamping arm and frame of the shaker head with a pin assembly which extends into a spherical bearing disposed within an aperture of the shaker head. The spherical bearing allows a certain amount of misalignment and provides a through-hardened and lubricated wear point which prevents or reduces structural failure in the shaker head components.

A shaped conveyor assembly configured for use in association with a harvester comprising a first side lower conveyor sub-assembly and a second lower conveyor sub-assembly. One or both of the sub-assemblies having a frame structure, a discharge assembly and a conveyor assembly. The frame structure has a gathering portion, an outward portion and a terminating portion. The gathering portion is positioned proximate the first end and spaced apart from the second end. The terminating portion is positioned proximate the second end and spaced apart from the first end. The outward portion extends therebetween, the outward portion being inclined in an upward direction relative to the gathering portion, and directed in an outward direction, thereby extending away from the channel, and away from the other one of the first side and the second side lower conveyor sub-assemblies.

A harvester having a frame, an agitating system and a product gathering system. The frame has a central portion configured to receive and pass plants therethrough. The agitating system is positioned within the central portion that has a first side agitating assembly further comprising an axle with an axis of rotation and a plural of axial wands extending axially outwardly therefrom in a spaced apart configuration. The axle has a first end which is both above and outboard of the second end and the axle is angled relative to a vertical plane bisecting the frame body from front to back thereof. The axial wands can be agitated. The product gathering system includes an outer guide wall positioned below the rotary agitator assembly. The outer guide wall is angled relative to a vertical plane bisecting the frame body from front to back thereof.

A shaker head including bilateral eccentric weights connected to a single motor by a chain system that maintains the relative positioning and angular velocity of the eccentric weights without variance or slippage, where the relative position of the eccentric weights may be adjusted during non-operation to accommodate application of the shaker to head various tasks. The bilateral weights may be arranged in substantially symmetrical positions with respect to the midline of the shake head to improve balance of the shaker head. The shaker head may also include a third shaker head at third position to reduce undesired and inefficient shaking patterns in the shaker head during operations. The shaker head may be adaptable to various vehicles and machinery, such as trucks and tractors. The shaker head is operable to engage the trunk or limbs of a tree for purposes of harvesting fruit from the tree.
