Abstract: Apparatus in a crop roll forming machine for improving the core formation of the crop rolls and for collecting particles of crop material lost from either the crop package or loose crop material during the roll formation process consisting of an elongated tailgate with a collection pan. The particles are recycled from the collection pan back into the roll forming region by the cooperative interaction of the tailgate collection pan and the upper bale forming means as the bale forming means traverses a predetermined path imparting rotative motion to the crop material delivered to the roll forming region.

Gear means is drivingly coupled between an opposite end of the output shaft and lower transversely extending shaft means which, in turn, is drivingly intercoupled to the lower roll, such that the lower roll is rotatably driven in a direction opposite to that of the upper roll.

Abstract: An agricultural harvester having a header pivotally connected to the forward end of said harvester and said header having a flexible floating cutterbar on the forward lower edge thereof and a rotary reel mounted for automatically adjustable movement toward and from said cutterbar by power means to prevent accidental contact between the same. The harvester also includes power means to elevate the header to enable the same to effect desired spacing from the surface of a field when the contour is such as to require the same. Sensing means responsive to the surface of a field control the operation of the respective power means for said reel and header automatically.

Abstract: An articulated top tension rail is provided in the bale chamber of a baler for improving control over the shape of bales successively formed within and moved toward the rear discharge end of the bale chamber. A tension control device on the bale chamber disposes a rear portion of the top rail in a position in which it is spaced above and substantially parallel to a bottom rail of the bale chamber and disposes a front portion of the top rail, which is pivotally connected to the rear portion, in a position in which it rearwardly declines toward the bottom rail.

Abstract: An axial flow type combine having a rotor provided with rasp bars operable relative to a concave to form a threshing region and provided at the inlet end of the threshing region with support means for the rotor adjustable to vary the distance between the rotor and concave. In the preferred construction of said support means, the forward end of the shaft of the rotor is mounted for movement toward and away from the inner surface of the concave.

Abstract: A tension control device is disclosed which is particularly well suited to chain drive systems subjected to cyclic forces. The device includes a tension-setting adjustment mechanism affixed to a pivoted mounting plate and an arm means pivoted at one end, at the same location as said mounting plate, supporting a sprocket for engagement with the chain. Biasing and stop means coact with the mounting plate and the arm means to urge them apart and limit the maximum and minimum separation therebetween.

Abstract: An adjustable mechanism is disclosed for controlling the amount of feeder penetration into the bale chamber of a hay baler. A three-element linkage interconnecting the baler plunger and the feeder mechanism causes the feeder to reciprocate along a predetermined path toward and away from the bale chamber in timed relationship to the plunger movement. One of the linkage elements is selectively adjustable in length to control travel of the feeder mechanism, and thus the amount of penetration.
