1. A powered square baler operable to form a bale by compressing loose material, the powered square baler comprising:
a chassis including a baler frame that presents a baling chamber to receive the loose material; and a reciprocating plunger assembly including a plunger head and an impulse device having a groove formed therein, the plunger head being slidably mounted relative to the frame and operable to be driven by a power source to reciprocate into and out of the chamber and apply a compressive force against the loose material, wherein the plunger head comprises a receiver having an end wall and a detent assembly for engaging the groove of the impulse device, the receiver operable to slidably receive the impulse device so that the impulse device can reciprocate into and out of the receiver, with an end wall of the impulse device operable to strike the end wall of the receiver such that the impulse device transmits energy to the plunger head, with the transmitted energy causing an impulse force to be applied against the loose material by the plunger head. |
