A round baler having storage and dispensing mechanisms for both twine and net/plastic wrapping materials for the bales can be modified to provide a lower cost twine baler. A pivoting dispensing assembly across the front of the baler is replaceable by a similar-sized twine box to convert the baler to an all-twine baler with sufficient twine storage to make the machine efficient in field operations.

Twine box for round balers

A pull type agricultural implement, such as a round baler, having a main frame, a pair of ground engaging wheels rotatably attached to the main frame for supporting the implement, a hitch assembly for attaching the main frame to a vehicle for towing the implement, and a locking mechanism operatively associated with the main frame for locking at least one of the wheels. The locking mechanism comprises a lock member moveable between a hold position in which the lock member precludes the rotation of the at least one of the wheels and a release position in which the lock member permits rotation of the at least one of the wheels. The locking mechanism further comprises a spring assembly for providing a force for holding the lock member in the hold position, and a camming arrangement for engaging the frame to provide a force to overcome the holding force to urge the lock member out of the hold position to the release position.

Parking lock for agricultural implement

An agricultural baler for making cylindrical bales of crop material having a sledge assembly moveable between bale starting and full bale positions. The sledge assembly includes a plurality of rollers which cooperate with an apron to define a bale forming chamber. A dispensing mechanism is carried on the sledge assembly for dispensing web material into the bale forming chamber whereupon it is wrapped circumferentially around a cylindrical package of crop material. A net supply assembly is associated with the dispensing mechanism to provide net for feeding into the bale chamber via the dispensing mechanism. Included along the feed path of the net is a net severing assembly for cutting the net after it has been wrapped around the cylindrical hay package. The net severing assembly includes a free falling knife for operatively engaging the net prior to entry into the chamber. A knife constraint system is employed to maintain the knife inoperative in a holding range while permitting it to fall in a release range. A control arrangement trips a latch that controls the knife drop under conditions where the constraint system is in the release range.
