摘要:
A walk-behind working tool having a frame, a power source, and a handle attached to the frame is provided. The working tool includes at least one axle operatively connected to the frame and a pair of wheel assemblies connected to the axle. The wheel assemblies include a hub, a rim, a tire, and a flexible vibration dampening assembly that operatively connects the hub and rim, wherein the dampening assembly is configured to reduce the vibration transferred between the rim and hub and through the handle to the operator. The dampening assembly includes a plurality of elastic elements having a spring constant for smoothing out movement of the frame when the working tool is guided over rough or uneven ground.
