Abstract
A wide area turf mower has a wheel supported main frame and cutting units movably connected to the main frame and positioned in rows in a staggered order to form a mower cutting configuration for cutting a continuous swath of turf between any two outer cutting units located respectively on opposite sides of the main frame. One row of the cutting units includes a first pair of pivotally interconnected outer and inner cutting units at a first side of the main frame, and a second pair of pivotally interconnected inner and outer cutting units at the second side of the main frame. First hydraulic cylinders cause the outer cutting units to fold in a direction towards the rear end of the main frame. Second hydraulic cylinders cause the inner cutting units to lift in an upward direction. A controller operates all of the hydraulic cylinders.

A wide area turf mower comprising:
- (a) a wheel supported main frame having a front end, a rear end and opposite first and second sides,
- (b) a plurality of cutting units movably connected to the main frame and positioned in rows in a staggered order to form a mower cutting configuration for cutting a continuous swath of turf between any two outer cutting units located respectively on the opposite first and second sides of the main frame,
- (c) one row of the cutting units comprising a first pair of interconnected outer and inner cutting units at the first side of the main frame, and a second pair of interconnected inner and outer cutting units at the second side of the main frame, each of the inner cutting units being pivotally connected to the main frame, each of the outer cutting units being pivotally connected to a respective inner cutting unit,
- (d) a first hydraulic cylinder for rotating each of the outer cutting units relative to its respective inner cutting unit about a respective vertical pivot axis, whereby each of the outer cutting units folds in a direction towards the rear end of the main frame,
- (e) a second hydraulic cylinder for rotating each of the inner cutting units relative to the main frame about a respective horizontal pivot axis, whereby each of the inner cutting units lifts in an upward direction, and
- (f) a controller for operating the first hydraulic cylinders and the second hydraulic cylinders.
