2. Designed purpose of use
The AVANT Aerator 1100 is an attachment that is suitable for use with AVANT compact loaders that are
shown in Table 1. The aerator is intended for cutting holes into the soil. The attachment is especially useful in
a more compacted soil for recovering the growth of lawn areas. For the best results, the aeration should be
done during the growing season.
The Avant Aerator 1100 is a free rolling attachment that can be pushed across the lawn. It has an aerating
axle with knife type blades installed to it. The blades penetrate the soil and aerates the growing lawn. The
aerating axle is equipped with 90 replaceable blades which loosen the soil. The blades are set to the
operating depth of 150 mm as standard. By repositioning the blades the operating depth can be set to the 110
mm, as well.
During use, only smooth turns with large turning radius are possible with the aerator on the ground, otherwise
the lawn or the aerator may get damaged. The aerator must be lifted off from the ground when making sharp
turns.
The Aerator 1100 is not designed for any other use than what is specified in this manual and must not be used
for any other purposes than what is intended for. The aerator is not intended for hard surfaces such as gravel
pathways or other similar areas.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional technicians. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT dealer if you have additional questions about the operation or maintenance of the equipment, or if you
require spare parts or maintenance services.
