Operator's Manual

Congratulations on your choice of an aerator from The
Toro Company to complement your turf care operation.
This machine has been designed and manufactured to
meet the needs of a discerning turf care industry.
For your safety and to aid in developing a better
understanding of your machine, all operators must read
the operators’ sections of this manual. The parts sections
are for reference only and do not require thorough
reading.
The parts on your aerator have been specifically
designed to give a highly reliable and long life. Only
The Toro Company or their representatives can offer you
the genuine parts. If other spurious parts are used, we are
unable to guarantee the performance or safety of this
machine and your warranty will be invalidated
INTENDED USE
Your aerator has been designed and constructed for a
specific use with exacting standards and sound
engineering principles.
If this machine is not used exclusively for its intended
purpose, safety is in jeopardy and the expected trouble-
free working life of the machine may be reduced.
This aerator is intended to aerate fine turf surfaces (golf
and bowling greens for example) by using a series of
hollow or solid tines which are driven into the turf
surface up to a depth of 125mm (5 inches).
Due to the intrinsic hazards of machinery of this type
when used with today’s sophisticated tractors, this
aerator should only be attached and used by qualified
personnel with sufficient experience who are fully
conversant with the tractor.
PRINCIPLES OF OPERATION
This aerator is mounted on a tractor’s three-point linkage
to lift and lower the machine out of and into work, or for
transport.
The tractor’s power take-off (PTO) power is transmitted
via shafts, gearbox and drive belts to crankshafts that
drive the tine holding con-rods into the turf surface.
As the tractor travels forward with the PTO engaged and
the machine lowered, a series of holes or slits are created
in the turf surface.
The depth of the tines’ penetration is determined by the
height of the depth control roller.
The distance between the holes created is determined by
the tractor’s forward speed and the number of tines in
each tine head.
