Before suspension of the machine, lower rods of the tractor’s suspension system shall be
in lower position at the same height (distance between joints and ground is minimum 200
mm). Rods set at the equal height from the ground facilitate mounting the ridger on the
tractor.
4.5. Assembly of the ridger
Ridgers from the manufacturer to a sales person or a client are transported partly
disassembled and therefore during the first run and preparation of the ridger for operation,
it shall be assembled. First, install the ridger frame on the tractor three-point suspension
system. Then on the frame, after raising it with the tractor lift and securing against falling
down, install the ridger working units. Position of the ridger units shall be set on the frame
by tightening two bolts fastening unit covers. After installing units, install the ridger working
elements by twisting off bolts fastening working elements caps in rails.
CAUTION
Assembly of the ridger shall be performed on the flat and even ground. Keep extreme
caution when installing the ridger body, knurls and duckfoot shares due to possibility
of danger of being hurt with sharp edges of the machine.
CAUTION
During assembly use the tables from the spare parts catalogue where connection of
ridger each element is presented.
4.6. Preparing the ridger to work
Preparation of a new ridger to operation and after storage period (e.g. after winter)
consists in
checking its technical condition and most of all durability of connections of
working elements with the frame. In case of stating damage or worn elements it is
necessary to exchange them into new or regenerated ones. Otherwise it can lead to
reduction of the tool work quality.
CAUTION
It is forbidden for the operator to stay between the tractor and the machine at the
tractor engine running. The ridger shall be raised easily, without jerks or vibrations.
Furthermore, it is necessary to:
-
check screw connections, in case of backlash tighten the nuts,
-
check if copying wheels move easily and without jamming, in case of stating jamming
of a copying wheel, it shall be uninstalled, cleaned and lubricated or bushings of
copying wheels shall be exchanged,
-
check if axles of articulated parallelograms and pull springs move easily and without
jamming, in case of stating jamming, they shall be cleaned and lubricated,
-
lubricate the ridger
in accordance with recommendations (see chapter ‘Lubrication
instruction’).
CAUTION
All maintenance in the ridger shall be performed before installing it on the tractor.
