A powered square baler is operable to form a bale by compressing loose material. The powered square baler broadly includes a chassis and a reciprocating plunger assembly. The chassis includes a baler frame that presents a baling chamber to receive the loose material. The reciprocating plunger assembly includes a plunger head and an energy storage device. The plunger head is slidably mounted relative to the frame and is 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. The energy storage device stores energy from the power source and transmits the energy to the plunger head in response to the applied compressive force, with the transmitted energy causing an impulse force to be applied against the loose material by the plunger head.

Square baler with plunger providing increased impact force

A powered square baler is operable to form a bale by compressing loose material. The powered square baler broadly includes a chassis, a plunger assembly, and a plunger drive. The chassis includes a baler frame that presents a baling chamber to receive the loose material. The plunger assembly includes a reciprocating plunger head and a pair of connecting arms attached to the plunger head. The reciprocating plunger head is slidably mounted relative to the frame and is operable to reciprocate into and out of the chamber and apply a compressive force to the loose material. The plunger drive includes a pair of planetary gear trains and a common drive shaft that powers both of the gear trains, with each gear train drivingly connected to a corresponding one of the connecting arms to cooperatively power the plunger assembly.

Square baler having planetary plunger drive

A powered square baler is operable to be powered by a prime mover to form a bale by compressing loose material. The powered square baler broadly includes a chassis, a plunger assembly, a flywheel, and a planetary gear train. The chassis includes a baler frame that presents a baling chamber to receive the loose material. The plunger assembly includes a reciprocating plunger head slidably mounted relative to the baler frame and operable to reciprocate into and out of the chamber and apply a compressive force to the loose material. The flywheel is rotatably mounted on the chassis and is operable to be driven by the prime mover. The planetary gear train is drivingly attached to the flywheel and is drivingly attached relative to the plunger assembly to transmit power between the flywheel and the plunger assembly and thereby drive the plunger head.
