1-2 DESCRIPTION
The ATH 900 cutter (Figure 1-1) is intended for cut-
ting lawns, golf courses, or any maintained area
where a clean, uniform finish is desired. Three paral-
lel uplift blades form a suction during operation to lift
the grass before cutting it. The four caster wheel
arrangement, along with the floating lift linkage and
an optional front mounted roller, all work together to
give an even cut and minimize scalping.
Power from the tractor is transmitted through a trian-
gular, telescoping driveline to the 90 degree gear-
box. It is then passed to the spindle housings and
blades by a single, C-section, Kevlar reinforced belt.
Drivetrain protection is provided by belt slippage.
