ABSTRACT:
Idlers used in the main drive chain on rectangular balers resist the accumulation of slack in the chain. Sudden stops of the drive apparatus cause the chain to be highly tensioned resulting in possible damage to the idler and the chain. An idler apparatus is provided with a first resilient member having a first spring rate for limiting the accumulation of slack in the chain. A second resilient member has a second spring rate for resisting tensioning of the chain.
