Coupling operations between a motorized vehicle and an attachment may be complicated when, due to uneven terrain, it becomes difficult to properly align a coupling component of the vehicle with a mating coupling component of the attachment. An adjustable coupling apparatus is provided which includes a coupling arm pivotally mounted on a support. An end of the arm includes a receptacle and an associated latch. The coupling arm is pivotable for varying the position of the receptacle.

A multi-row crop header for a harvesting machine has a plurality of fore-and-aft extending row crop units, each having an elongated passageway with a front inlet opening and a rear discharge opening. The row crop units are pivotally mounted such that they can be swung toward and away from one another so as to vary the lateral distance between the inlet openings of adjacent units to thereby accommodate crops planted in various width row spacings.

A quick-adjusting jackstand apparatus is particularly useful on any harvesting attachments. An improved jackstand has a coarse adjustment and a fine adjustment. Coarse adjustment is accomplished by moving the jackstand from a first stored position to a second extended position. A secondary fine adjustment is accomplished by rotating an inner member which is housed in and threadedly engaged with an outer member. Such rotation results in extension of the inner member from the outer member. The threaded engagement of the members is protected from excessive clogging because such threaded engagement is within the outer member.

A shredbar is used with a forage harvester cutterhead mainly for cracking kernels of corn. The problem of premature wear of the shredbar is avoided by providing a shredbar apparatus with a reversible surface for abrading crop material. The shredbar apparatus includes pivotal members to increase flexibility for quick installation and removal.
