Abstract

A square baler (30) includes a chassis (32), a plunger (36), and a variable speed transmission (42). The plunger assembly (36) includes a reciprocating plunger head (76) slidably mounted relative to the chassis (32) and operable to reciprocate within a chamber (54) to apply a compressive force against the material. The transmission (42) includes drive (86) and driven components (90) and an endless drive element (98) that drivingly interconnects the components. The driven component is drivingly connected to the plunger head. The drive component is operable to be driven by a prime mover at a drive input speed. At least one of the components has an adjustable operating diameter so that the driven component has a variable output speed.
