Abstract
A mass damper is carried on the frame of an reel mower by a pair of elastomeric couplers, one at each end of the mass damper. Each coupler is threadedly secured to one end of the mass damper with the coupler received in a cavity at that end of the mass damper. Each coupler is also clamped to a bracket on the frame of the reel mower. The mass damper can move relative to the frame of the reel mower by shearing the elastomeric material forming the couplers. The weight of the mass damper and the stiffness of the couplers is chosen to damp or lessen the vibration induced in the frame of the reel mower by an internal combustion engine carried on the frame of the reel mower.
