A beet scalper includes an upwardly biased parallel arm linkage, a boom, having an upper end coupled to the parallel arm linkage and a lower end bearing a beet scalping blade, and a locking mechanism, holding the boom in a downward operating position. Forward deflection of the lower end of the boom releases the locking mechanism, allowing the boom to rise to a tripped position under force of a biasing mechanism associated with the parallel arm linkage.

The invention relates to a foliage-processing device movable over land in a direction of travel for foliage of tuberous plants growing in rows on the land, wherein the foliage-processing device is provided with: at least one haulm topper provided with arms rotating about a rotation axis with which the haulm is to be broken up and with which parts of the broken-up haulm are to be led away in a direction not directed towards the land; at least one haulm puller provided with at least two rollers rotating opposite to one another between which the haulm is be gripped, and is to be pulled away in a direction not directed towards the land; at least one discharge mechanism with which broken-up and pulled haulm is to be set down next to a row or between the rows of the tuberous plants growing on the land.

The beet head trimming apparatus for a beet-harvesting machine comprises a frame, two flail hubs rotatable about an axis, flails, which are designed in order to remove leaves from beets remaining in the ground, and a drive in order to drive the flail hubs with respect to the frame. The drive comprises a motor and a gearbox and the flails are movably attached to the flail hubs. The motor and the gearbox are attached to the frame. The frame of the beet head trimming apparatus is coupled with a beet-harvesting machine. The beet head trimming apparatus couples the motor with an electrical and/or hydraulic energy source. The beet head trimming apparatus is a module that can be handled separately from the beet-harvesting machine.

Disclosed are an array cutting knife-type cotton topping machine and a control method thereof. The cotton topping machine includes cameras, controllers, a tacho-generator and a plurality of groups of topping assemblies arranged in a left-right direction; the cameras and the tacho-generator are connected to the controllers; and a plurality of topping devices staggered left and right are arranged for each planting row. In the present disclosure, by densely arranging low-cost topping devices and determining which topping devices are switched to an operating state for topping according to visually determined top bud positions, the potential problems in the prior art of the damage to other parts of the plant or the unnecessary intertwining of branches and leaves are avoided.

A haulm cutting apparatus includes lateral and vertical guiding means or surfaces and a first, rotatable shear rotatable around an axis of rotation extending in a direction with a vertical component. The apparatus further includes a counter shear for cooperation with the first, rotatable shear, and the first, rotatable shear and the counter shear are positioned in a side-by-side relationship relative to a direction of travel during operation.
