1.1. Purpose of use
The Multiva disc cultivator is intended for shallow primar tillage (stubble cultivation) in the autumn or
spring, the main purpose of which is to loosen and aerate the soil, bur plant residue and prepare the
soil for cultivation. The disc cultivator can also be used for seedbed preparation. Use of the disc
cultivator for any other purpose is prohibited! Stubble cultivation performed with the disc cultivator
buries plant residue under the surface la er of the soil and compresses the surface of the field. The
machine is particularl well-suited to stubble cultivation, thanks to its excellent efficienc in bur ing
plant residue and its adjustable working depth.
The Multiva cultivators are equipped with thick 5 mm conical discs that can penetrate hard soil
extremel well. To prevent breakage due to rocks and other obstacles, the discs have been fitted with
rubber suspension mechanisms. The weight of the cultivator (adjustable with additional weight), its
open frame structure and the dense row of roller plates are also essential in achieving an even result.

2.2. Connecting and disconnecting the cultivator
The machine can onl be connected to a tractor’s three-point lifting device. The cultivator fitted with
towing equipment is connected to the tractor’s link arms. All tractor safet instructions must be
observed when connecting or disconnecting the machine. The connection and disconnection of the
cultivator pose the danger of crushing. Moreover, ou must exercise caution not to injure our feet,
fingers or hands. Touching the h draulic c linders, hoses and h draulic connectors is strictl prohibited
when the c linders are in operation. When the cultivator is connected to a tractor, unauthorised persons
must be cleared from the vicinit of the machiner .
2.3. Transport on public roads
When transporting the cultivator on public roads, alwa s exercise caution and observe all laws and
regulations applicable to road traffic and slow-moving vehicles. Before departure, check the operation
and visibilit of the machine’s reflectors and lights as well as those of the tractor. Before road transport,
alwa s ensure that the machine is sufficientl clean. Do not transport or operate the machine when ill,
excessivel fatigued or under the influence of alcohol. The driver is responsible for an injuries and
damage caused b the machine to other persons. The highest permissible speed for a cultivator with
towing equipment is 40 km/h.
NOTE! In order to reduce the total width for road transport, the levelling disc of the DiscMaster 400
model must be detached and placed in the transport mount so that the machine does not exceed
the maximum transport width permitted b the road traffic legislation. The DiscMaster 350 and 300
models also include a transport mount for the levelling disc, and it is alwa s advisable to use the rack in
road transport.
2.4. Using the disc cultivator
The driver must be familiar with the cultivator’s operation. In addition, he or she must have the
sufficient knowledge and skill to properl use the machine. The driver must carefull read the operation
manual and observe its instructions.
When connecting a disc cultivator to a tractor’s lifting device, the weight distribution between the
tractor’s front and rear axles changes. In order to ensure safe operation and optimal towing power,
install front weights on the tractor, if necessar .
Before beginning work, alwa s check the condition of the machine and the tightness of the bolts. Never
adjust or clean a moving machine. All persons are strictl prohibited from being on the machine or
within its operating range (safet distance 5 m) when it is in operation. For purposes other than
adjustment, avoid reversing the machine when the discs are lowered. To avoid blockages, ou should
also avoid reversing the machine when the roller is down. During cultivation do not perform tight
turns with the discs down. Instead raise the cultivator when turning.
Touching the hydraulic cylinders hoses and hydraulic connectors is strictly prohibited when the
cylinders are in operation.
When installing or removing additional weights, ou must exercise caution not to injure our feet,
fingers or hands.
2.5. Maintenance
Alwa s stop the machine and prevent its movement for the duration of maintenance. The maintenance
must be performed on an even and stable foundation in order to ensure that the cultivator cannot tip
over or move. Do not conduct maintenance or other measures when the machine or one of its
components is raised and unsupported. When maintaining the machine, ensure safe working
conditions and sufficient illumination.

3. ME SURES BEFORE USING THE M CHINE
The machine has been lubricated for the first time at the factor . However, it is advisable to familiarise
ourself with the lubrication points before initial use. The lubrication points are listed in Section 7.2 of
this manual.
3.1. Connecting the cultivator to a tractor
Connect the disc cultivator to the tractor’s three-point lifting device (categor II or III connection). The
attachment point for the top link bar in the tractor must be lower than in the cultivator. Lock the pins of
the drawbars and push bar with linchpins. Adjust the side limiters in such a wa that the lock the
cultivator in the centre of the lifting device. The correct adjustment will prevent the machine from
contacting with the tractor and its t res. When working under variable conditions and during road
transport, the side limiters must alwa s be locked. Connect the h draulic hoses for the working depth
adjustment to the double-acting outlet. When disconnecting the machine from the tractor, alwa s
remember to disconnect the h draulic hoses.
3.2. Towing equipment
With the towing equipment, a lifting device-mounted disc cultivator can be arranged for towing. The
towing equipment includes a tow bar, wheel set and frame attachments. The frame attachments are
fastened to the machine's original frame with bolts. The tow bar is connected to the tractor’s drawbars.
The tow bar fastenings are accordant with categor II. The tractor drawbars should be left in the
horizontal position as much as this is possible. In this wa , the disc cultivator will not force the tractor in
an direction. The drawbars must under no circumstances be directed downwards, as this will cause the
tractor to lift the front end of the cultivator, resulting in variable working depth under various
conditions. The side limiters must alwa s be locked when the towing equipment is used. The towing
equipment requires one double-acting outlet from the tractor h draulics for wheel operation.
During cultivation, the machine can be made lighter to drag b lowering the wheel set. When on
headland, the cultivator can be raised to rest on the wheels or rollers. During cultivation, the wheel set
should be raised up to a position where it is suspended b the c linders. This keeps the wheels cleaner,
and unnecessar soil is not carried onto roads and highwa s.

4. DJUSTING THE M CHINE
4.1. djusting the position of the machine
The lateral position of lifting device-mounted cultivators can be adjusted b positioning the tractor
drawbars at the same height, so that the cultivator is level in relation to the tractor. The horizontal
alignment of the machine frame can be longitudinall changed b adjusting the length of the tractors
top link. During cultivation the machine's frame must be level in relation to the ground both
laterally and longitudinally.
Cultivators with towing equipment can be adjusted to run level b changing the length of the towing
bar’s top link (Figure 1, item 1). The working depth is adjusted b changing the length of the roller’s
h draulic c linder (Figure 1, item 2) . When changing the working depth, the cultivator's position should
be levelled adjusting the height of the drawbars or the length of the top link bar.
Figure 1. Towing equipment with a disc roller
4.2. djusting cultivation depth
To adjust the cultivation depth, change the height of the roller in relation to the machine’s frame. The
adjustment can be made b changing the thickness and number of the depth c linder control blocks
(Figure 2, item 1.). Removing blocks increases cultivation depth while adding them reduces the depth.
The cultivation depth must alwa s be measured from the cultivated soil behind the machine. Adjust the
cultivation depth in accordance with the conditions of each field section.
