tomer.  Your  Air  Turf  Hog  Series  Rotary  Cutter  has

instructions  for  keeping  your  rotary  cutter  in  top
operating  condition.  Please  read  this  manual  thor-
oughly. Understand what each control is for and how

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.
