Abstract: A cutting deck height adjustment system utilizing cutting height adjustment pins. The pins include two or more first holes that each define an axis that is parallel to the other. At least one third hole may be located longitudinally between the two or more first holes. The third hole defines an axis that is skewed relative to the axes of the two or more first holes. The axes of each of the first, second, and third holes may, in one embodiment, be normal to a longitudinal axis of the adjustment pin. By skewing the third hole, adjacent holes may be located in close proximity to one another while maintaining adequate structural integrity of the pin when a hairpin is inserted into one of the holes.

Abstract: A drive system for use with an endless drive member, e.g., a belt. The drive system may utilize an idler pulley that, in a first position, tensions the belt sufficiently to ensure power transmission between a driving pulley and a driven pulley. The idler pulley may be also be moved to a second position. In the second position, the idler pulley may both: relax tension in the belt to terminate power transmission to the driven pulley; and contact a brake member to quickly stop idler pulley rotation. Belt tension may then stop rotation of downstream driven pulleys. As a result, disengagement of the drive system and active braking of the idler pulley (and thus the driven pulleys) may both be accomplished via a single motion of the idler pulley.
