Machine description
Grass-Roller is a roller for consolidation of grassland. With water in the smooth steel rollers a high
weight is achieved and with that effective consolidation which guarantees an evenly pressed
grassland. This helps achieve the highest yield from the grass and good quality clean silage without
soil, stones, spores etc. With a hydr. long finger harrow in 2 rows mounted in front of the Grass-
Roller the grass can be ripped out and dead thatch can be removed or divided into fine particles.
The Grass-Roller can be equipped with Spring-Board levelling bar or molehill bar mounted on the
long finger harrow for levelling of molehills, cow pats etc., which helps avoid ingress of soil and
foreign matter into fodder when harvested. Add a HE-VA Multi-Seeder onto the Grass-Roller and
grass or other seeds can be drilled at the same time as the consolidation. This allows complete
reseeding, and overseeding or patching in existing pastures.

Safety instructions
General information
Do not start-up the machine if there are persons in exposed positions* within a hazardous area**.
When persons are in exposed positions (e.g. in connection with adjustment, maintenance, attachment
and uncoupling), the following conditions must be observed:
The machine must be lowered to firm ground.
The hydraulics must be relieved.
The tractor must be stopped and the key removed from the ignition switch.
The driver must ensure that no persons are staying in exposed positions during the operation.
* Persons in exposed positions: Any person who is staying wholly or partly within a
hazardous area.
** Hazardous area: On and under the machine within a distance of 4 m from the machine.
Most accidents that happen in connection with the operation, transport and maintenance of machines
are caused by non-compliance with the most elementary safety conditions.
Therefore it is vital that anybody working at the machine carefully complies with the safety
instructions as well as other instructions applying to the machine.
The machine may only be operated, maintained and repaired by persons, who are familiar with this
work and who are further familiar with the possible elements of danger with this particular machine.
Instructions on transport on the public roads:
Check before transport on public roads that the attachment of the machine at the tractor is in
accordance with the local rules and regulations in force (permitted total weight, permitted axle load,
transport width, lights, warning signs, etc.).
Front axle load:
After the attachment of the machine and at maximum load, the driving properties of the tractor must be
checked. Check that the front axle is sufficiently loaded. As a minimum, the front axle load must be
20% of the tractor weight. Permitted axle load and permitted total weight for the tractor must always
be observed.
NB! The driving, controlling and braking properties are affected by the attached machine
combination.

Operating Instructions
Attachment
On delivery the roller is in transport position. At start-up the roller is attached to the tractor.
Important:
Raise the support leg and place it in the transport fittings on top of the drawbar. Now fit all the
hydraulic hoses.
The roller requires two double-acting hydraulic outlets.
The hoses for the tip cylinder are provided with red cable straps.
The hoses for the wing cylinder are provided with blue cable straps.
The hoses for the long finger harrow are provided with green straps (extra equipment).
Power plug and control box for weight transfer protection are putted into the cabin (8.2m models)
Unfolding and folding of the machine
1. Check that the male quick couplings mounted from the factory fit the tractor’s female quick
couplings.
2. Contact on the control box for weight transfer protection activated (diode lights up)
3. Now pressurise the tip-cylinder (red), so that the side sections are lifted free of the transport
cradle.
4. Then the wing-cylinders are pressured (blue), so that the side sections are folded out as much
as possible, the hydraulic rams being fully closed.
5. Now relieve the pressure of the tip-cylinder (red), and the roller will tip forward, down to
working position. When the bottom has been reached, let go of the hydraulic handle.
6. Contact on the control box for weight transfer protection de-activated (diode off)
7. Now the wing-cylinders are pressured (blue), so that the side sections are pressed down
against the ground and the manometer is showing the hydraulic pressure according to the
schedule on the next page in order to obtain the correct weight transfer between the middle
section and the side sections.
Change-over from working to transport position
8. Contact on the control box for weight transfer protection activated (diode lights up)
9. First the side sections are lifted free of the ground by pressurising the wing-cylinders (blue).
10. The roller is tipped completely backwards and is locked by pressurising the tip-cylinder (red).
11. Now pressurise the wing-cylinders (blue), so that the side sections are turning forwards,
towards the stop on the transport fittings of the drawbar.
12. When both side sections are parallel with the drawbar, they are lowered down into the
transport cradle by relieving the tip-cylinder (red). This is to be performed with care.
13. Contact on the control box for weight transfer protection de-activated (diode off)
Important: You must not pressurise any cylinders in transport position.
14. All hydraulic hoses are relieved, and the machine is ready for transport.
Check that the towing hook height is between
500 and 550 mm.

Settings and adjustment
Weight transfer
The weight transfer is adjusted dependent on the water quantity in the rollers. The weight transfer is
adjusted by pressurising the hydraulic system (blue).
The pressure is read on the machine’s manometer.
NOTE: The weight transfer system can be loaded with max. 100 bar.
Long finger harrow
The long finger harrow is raised and lowered with the hydraulic system, which is marked with the
green colour.
During work the long finger harrow can be raised and lowered as required. However, you have to take
care that the harrow does not work too deeply meaning that it will carry the whole roller’s weight.
Recommended harrow depth: 25 mm below the roller.
The front harrow is to operate in horizontal position when the machine is in working position. This is
adjusted on the parallel rods, by loosening the nuts on each parallel rod and by tightening on the
opposite side.
Each tine can be worn approx. 200 mm. However, they will be less flexible and maybe there is a need
for an earlier replacement.

Levelling board
The levelling board is raised in proportion to the wear and tear
of the tines. This is performed by loosening 2 nuts , and
hereafter screwing with a 19 mm spanner on the thread
spindle, which determines the height . When the desired
height is reached, the 2 nuts are tightened again .
Be sure that all adjusters are set the same otherwise the
levelling board will operate unevenly. This is easily done by
measuring the length of the spindle.

Roller scraper
6.3 m
The scrapers are bolted on the end plates. In order to adjust the scraper bar loosen the 2 bolts at the
top and push the scraper bar against the roller . Please be aware that the scraper bar is to be
placed 5 –10 mm from the roller.
8.2 m
The scrapers are adjusted in the same way as for 6.3 m. In the
middle of the side sections 2 bolts are placed, which are to be
loosened too.
Maintenance
Lubrication
Important:
After every approx. 10 working hours all movable parts in the side sections are to be lubricated as
well as the 3 lubricating points on the wing cylinder. After every 30 working hours the tip cylinder’s
pins and the 3 pins in the drawbar are to be lubricated.
The bearings of the roller are to be lubricated after every 100 working hours and/or after cleaning.
Important:
After the season, the roller is to be cleaned and lubricated with grease and oil.
Important:
Repairs
All repairs are to be performed with original HE-VA spare parts.

After every approx. 10 working hours
the wheels, ball bearings and stop rings
are tightened. Hoses, fittings and
cylinders are inspected for eventual
leaks and are tightened too.

UK Grass-Roller 6.3m /8.2m 13/07-2018

Spring-Board
The Spring-Board requires 1 double-acting hydraulic outlet on the tractor. The tine angle and thereby the
aggressiveness of the tines is hydraulically controlled from the driver's cab and the depth control is done
manually. The Spring-Board tine bar is adjustable in height and thereby the working angle of the tines
against the ground is being changed. The tines work independently, but may be connected by means of a
transverse locking system (extra equipment) if a greater levelling effect is required. The change-over is
done very easily and quickly without any tools.
Mounting of cylinder on Spring-Board
The hydraulic cylinders are mounted as shown below. It is important that the mounting is performed
properly to get the correct force on the cylinders.
On the Grass-Roller the cylinders for Spring-Board must be mounted in hole 2 and 2b. Moreover, the tine
points of the Spring-Board tines are placed completely down, so that they are bolted in the lower holes.
