Abstract

An adjustable tailgate latching mechanism for a round bale utilizing a movable arcuate hook-like latch catching structure attached to the latching mechanism that enables proper alignment of the tailgate latch to be established and maintained.

Claims (6)

1. In an agricultural round baler having a forward end, an opposing rear end and opposing first and second sides, a bale-forming chamber, a tailgate rotatable attached to the baler and movable between opposing open and closed positions, an actuator for selectively moving the tailgate, a latch pin disposed on the tailgate, and a latch mechanism for selectively securing the latch pin thereby securing the tailgate in the closed position, the improvement in the latching mechanism comprising:

an elongate lever arm having a first end and a generally opposing second end defining a longitudinal axis therebetween, said elongate lever arm having the first end pivotally connected to the first side, said first and second ends separated by a pivot axis, said lever arm pivotable about said pivot axis between latched and unlatched positions;

a catch plate connected to the second end of said lever arm by at least one fastener, said plate having a catch structure for engaging the latch pin when said lever arm is in said latched position and for allowing said latch pin to move when said tailgate moves when said lever arm is in said unlatched position; and

at least one slot at said second end of said lever arm, said at least one slot for engagement by said at least one fastener to permit selective movement of said plate relative to said lever arm, said at least one slot is aligned to limit selective movement of said catch plate to movement along a single axis, said single axis is generally perpendicularly disposed with respect to said longitudinal axis, whereby said latch mechanism may be adjusted to accommodate variations in position of said latch pin on the tailgate within the plane of rotation of the tailgate.

2. The improvement of claim 1 , wherein said at least one slot comprises a plurality of generally parallel slots.

3. The improvement of claim 2 , further comprising a second latch mechanism disposed on the second side of the baler wherein said second latch mechanism features the improvement of the first latch mechanism.
