4. USAGE REGULATIONS
4.1. General information
The P475 series mounted ridgers are manufactured in two working versions as a 3-
section machine for 3 rows or 5-section machine for 5 rows. Mounted ridgers of P475
series are suitable for operation on slopes not exceeding 8.5and cooperate with tractor
classes 0.6 and 0.9 (see technical characteristics - table 4) equipped with standard wheel
ballasts.
4.2. Construction and operation of the machine
The U724 series ridgers (Figure 1) are tools mounted on the three-point tractor
suspension system equipped with the suspension category II. Construction of the ridger is
modular, i.e. ridgers have the same working sections but only differ in the frame.
The ridger working sections are mounted with the yoke 10 to the ridger frame 1
(figure 1) equipped with a tool three-point suspension on the tractor. The working sections
have articulated parallelograms 2 which provide an equal operating angle for the ridger
operating units. In the parallelogram there is a spring tensioner 3 which facilitates
immersion of ridging coulters 4, a ripper 5 and a cultivator point 6. During the operation,
the ridger frame is supported on the copying wheels 7 of the working sections. The ridging
body consists of a two-sided ploughshare, a mouldboard and two wings. The ploughshare
passes the undercut soil onto the mouldboard. The mouldboard partly rakes the soil to the
sides and passes it to the wings. Wings form a ridge and spread soil under plants. There
are brackets 2 for installing light and warning devices, and a triangular sign for low-speed
vehicles welded to the ridger frame.

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.
