Abstract: A mower blade assembly attaches to a rotatable spindle and includes a mounting plate which defines a first pin aperture. The mounting plate and a retaining plate are attached to the rotatable spindle. The retaining plate defines a second pin aperture. A movable pin plate comprises a pin. A blade is selectively attachable to the mounting plate. The blade defines a retaining plate aperture and a third pin aperture. A biasing member urges the movable pin plate from a disengaged position to an engaged position. The pin is engageable with the pin apertures for mounting and retaining the cutting blade to the mounting plate. The blade is attached by moving the blade over the retaining plate aperture, urging the movable pin plate to the disengaged position, rotating the blade, and releasing the movable pin plate. Another embodiment includes a force finger.

Abstract: A clutch assembly attachable to a rotational output shaft of the engine, wherein the clutch assembly is configured to drive at least one implement of a lawn maintenance vehicle is provided. The clutch assembly includes a first pulley fixedly attached to the output shaft, a second pulley independently rotatable relative to the first pulley, and a belt extending between the first and second pulleys and an idler pulley that is movable between an engaged position and a disengaged position. The clutch assembly further includes a third pulley directly connected with the second pulley, wherein rotation of the second pulley is directly transferred to the third pulley, and rotation of the third pulley provides an output rotation of the clutch assembly.

Abstract: In a broad respect, vehicles that are capable of making a low- to zero-radius turn using the independent rotation of drive wheels and by turning the non-driving steerable structure or structures (such as wheels) with a steering input device (in some embodiments, the driving wheels also may be capable of being turned). This may be accomplished using a steering system, a speed control system and an integration device (together, a control system) that are configured to work together to provide correct steering in forward and reverse, and, in some embodiments, to reduce the speed of the outboard drive wheel of the vehicle when it enters an extreme turn under constant speed input. Different systems configured for use in such vehicles are included.
