Twine wrapping apparatus for a round baler having a bale forming chamber with a generally transverse crop infeed opening. The apparatus is mounted forward of the opening and includes an extendable twine arm for dispensing twine into the chamber to wrap bales formed therein. A coupling mechanism provides controlled swinging movement of the arm through a predetermined path that originates in the middle of the opening. The twine arm is in its outermost extended condition at the initiation of the twine dispensing phase and retracts as it travels along its path to a generally transverse rest position.

A row crop attachment for forage harvesters includes a plurality of row crop divider units arranged side-by-side on a base frame to define a plurality of crop conveying paths. Gathering chains are arranged to pass through each crop conveying path from an entrance to an exit thereof for conveying crop material through the crop conveying paths. Rotary knives are disposed adjacent the entrance of each crop conveying path for cutting off crop material before it is conveyed rearwardly through the crop conveying paths by the gathering chains. An auger is disposed adjacent the exits of the crop conveying paths for converging crop material exiting from the crop conveying paths toward a longitudinal center line of the row crop attachment. A filler ramp is positioned underneath the auger along this longitudinal center line behind the row crop divider units to prevent accumulation of crop material near the exits of the crop conveying paths.

A row crop attachment for forage harvesters has a plurality of row crop divider units arranged side-by-side on a base frame to define a plurality of crop conveying paths. A pair of gathering chains are arranged to pass through each crop conveying path from an entrance to an exit thereof, and a pair of rotary knives are disposed adjacent the entrance of each crop conveying path. Each gathering chain is wrapped around a drive sprocket and a pair of idler sprockets. The drive sprockets are located near the exits of the crop conveying paths, and the idler sprockets are located near the entrances of the crop conveying paths. One idler sprocket of each pair also serves to drive one of the rotary knives while the other idler sprocket of each pair is supported in a cantilevered manner forwardly of the rotary knives.

Apparatus for wrapping cylindrical bales of crop material with twine includes a feed roller, a knife, and a twine arm connected to an electrical actuator for dispensing twine. The electrical actuator is extendable and retractable in order to cause pivoting movement of the twine arm between a rest position, a twine dispensing position and a twine cutting position. A first link is connected between the electrical actuator and a crank lever, and a second link is connected between the crank lever and the twine arm. Extension of the electrical actuator moves the twine arm from the rest position to the dispensing position and simultaneously results in the feed roller being driven. Retraction of the electrical actuator moves the twine arm from the twine dispensing position toward the twine cutting position while the feed roller continues to be driven. When the electrical actuator is fully retracted, the twine arm is moved into the twine cutting position and the knife is actuated.

Apparatus for wrapping bales with twine

A method of wrapping cylindrical bales of crop material with twine includes extending and retracting an electrical actuator to cause pivoting movement of a twine arm. When the electrical actuator is extended, the twine arm is moved from a rest position to a twine dispensing position and a feed roller is simultaneously driven to feed twine that is dispensed by the twine arm. Retraction of the electrical actuator moves the twine arm from the twine dispensing position toward a twine cutting position while the feed roller continues to be driven. When the electrical actuator is retracted further, the twine arm is moved into the twine cutting position and a knife is simultaneously actuated to cut the twine.

A windguard for use on the pick-up mechanism of a crop harvesting machine. The windguard automatically adjusts to varying sizes of windrows of crop material as the machine and its pick-up mechanism are being operated. The windguard has an unlimited number of adjustment positions for different sizes of windrows.

A roll baling machine includes an apron supported on a base frame and movable in suitable manner to form roll bales of crop material. A bale retainer is mounted on the base frame to momentarily hold a roll bale upward in the base frame during its discharge therefrom. The bale retainer is movable from an inoperative position during bale formation to an operative position during discharge of a roll bale from the base frame.

In a roll baling machine, a portion of the bale chamber is tapered in width from top to bottom or from rear to front to facilitate bale ejection.

In a crop roll forming machine adapted to be towed across a field, a kicker means is fastened to the opposing sides of the frame and extends at least partially therebetween adjacent the conveying means and the rear end so that upon completion of the formation of the crop roll the roll is ejected from the bale forming region into contact with the kicker means which propels it rearwardly of the roll forming machine.
