A reel mower has a plurality of reel cutting units comprising a pair of laterally spaced front cutting units ahead of the front wheels of the mower and a center rear cutting unit between the front and rear wheels of the mower. A pivotal footrest in front of the operators seat may be selectively swung to the side to clear an open space in front of the seat in which the center rear cutting unit is at least partially received. This permits an operator or mechanic to easily reach the center rear cutting unit by walking through the lateral space between the front cutting units into the open space that contains the center rear cutting unit.
