Tractor These cutting units will mount on any Toro riding Greensmaster.
Height of Cut Cutting height is adjusted on front roller by two vertical screws and held by two locking cap screws. Bench HOC range is .062-.297"
(1.6-7.5 mm). With high HOC kit, range is .285-1" (7.3-25.4 mm). Effective HOC may vary depending on turf conditions and
bedknife installed.
Reel Weldment Reels are 5" (13 cm) in diameter, 21" (53.3 cm) in length. High carbon steel blades are welded to 5 stamped steel spiders, and heat
treated to RC 48-54 hardness. The reel is ground for diameter and concentricity, and backgrind.
Reel Bearings Two double row, self-aligning ball bearings, 30 +/-.1 mm inside diameter slip fit onto reel shaft with lock nut. Multiple seal barriers on
both sides of bearing for added protection. Reel position maintained by a wave washer with no adjusting nut.
Maintenance No grease zerks, sealed bearing design eliminates daily maintenance.
Reel Drive The reel weldment shaft is a 1.375" (35 mm) diameter tube with drive inserts permanently pressed in both ends. A replaceable floating
coupler with an internal eight tooth spline is factory installed on the right end, and held in place by a snap ring. The floating coupler
may be moved to the other end when the cutting unit is used on the GR3250-D front right position.
