ABSTRACT:
A lawn mower has a plurality of wheels each having a shaft, and housing means carrying a cutting element and drive means for driving the latter. The housing means are connected to the shafts movably relative to the same so as to change the distance between the housing means and the shafts to thereby correspondingly change the cutting height of the cutting element. Energy storing means are provided between the housing means and at least one of the shafts and adapted to counteract the weight of the housing means, the drive means and the cutting element so as to aid a user in upwardly adjusting the cutting element. The energy storing means may be formed as a spring, one end portion of which is connected to the housing means and another end portion is connected to a bracket provided on at least one shaft. Brackets of all the shafts may be connected with one another by a connecting member, which connecting member serves at the same time as an adjusting member so that the simultaneous adjustment of the distance between the housing means and the shafts of all the wheels of the lawn mower can be performed.
