Mower with scissor lift mowing height adjustment mechanism

A reduced weight underbelly mower has a cutting deck suspended beneath a frame by a deck height adjustment mechanism with a pivotable scissor configuration. The deck height adjustment mechanism cooperates with the mower frame so as manually or through a motorized jack to adjust the cutting height. Due to the mower's reduced weight and the scissor-like configuration of the deck height adjustment mechanism, an operator can manually lift the mower front end and swing the deck rear swinging forward, such that the mower rests stabilly on the deck rear and the deck underside is exposed for maintenance procedures.
