4. Remarks to the road safety
While using public roads and ways the combination of tractor and asparagus dam-
former must fulfil the rules of road traffic.
You have to pay attention to the maximum axle load and the maximum load
capacity on the tire of the tractor gets not overstepped.
You have to prevent the machine from swinging while the driving by fixing the
lower fixing points.
After the working you have to prevent that the public streets will be polluted with
soil.
5. Using possibilities
The dam-former Leofant has to be used only as agreed. You can build with the
dam-former Leofant in one or several processes asparagus dams. This machine is
also suitable for re-building the dams during the harvesting-season.
6. Functioning
With our dam-former Leofant you can build every form of a dam desired with every
kind of soil. Two counter-rotating double-stars of screwed square sticks make sure
the evenly, clod-free building of the asparagus dam. The dam-formers are
adjustable in the height and in the width. The asparagus dam is build up from
bottom to top and therefore it is very solid and durable against heavy rain. With
two adjustable supporting wheels you have a regular depth control. Metal soil
leveller mounted behind the supporting wheels make the driving lines optimally
level.

7. Starting up
Please check up before the starting up, whether the machine is delivered
completely. Parts, which are delivered separately, have to been mounted before
the first using. All lubrication points have to be lubricated; all gliding pieces have to
be fitted intensively with grease or oil. You have to check the content of oil before
the first using.
For using with a tractor of more than 120 HP, we recommend the use of
„Carter SH 320“ High performance oil. You have to change the oil at least
once per year!
7.1 Mounting to the tractor
7.1.1 Adjustments
Before starting the adjustments you have to pay attention to the fact, that the dam-
former Leofant has to hang horizontally behind the tractor and that the lower links are
uniform in the length.
Mount the dam-former Leofant to the 3-point link of the tractor.
Please adjust the length of the top link that the machine is hanging in its
working position, lowering about 5cm to the wheels, behind the tractor.
You have fix the lower links in that way that while working on the field a
tolerance of 1 cm on both sides is possible.
Now put on the PTO shaft. The minimum covering of the profile pipe may not be
remained under 250mm.
The guarding and protection installations of the PTO shaft have to be
mounted and to be good condition. Damaged parts have to be replaced
immediately.
7.2Milling of an asparagus dam
You have to do the following adjustments to mill an asparagus dam:
The front tins (optional) should have been adjusted the way that loosen the soil in
the driving line of the tractor. The working depth has to be adapted to the sticks
on the rotors.
The supporting wheels (image 3, pos.: 5) may be adjusted in the height from 0-
300 mm infinitely variable. The chosen adjustment depends on the desired height
of the asparagus dam.
The soil which is thrown by the rotors to the middle will build a trapezium-
shaped dam by dam former.
The width of the bottom of the dam can be adjusted infinitely variable by
adjustment-spindles (image 3, pos.: 4).
At the top you can adjust the width by the turning points (image 3 pos.: 1).

© HMF, 48336 Sassenberg-Füchtorf Seite 10
Image 3: Adjustment possibilities of the dam-former
You can adjust infinitely variable from 300-800 mm the height of the dam you wish
by the help of the spindle (image 3 pos.: 6). Due to that fact also the width of the
top of the dam is changing. The changing of the dam height by this spindle has no
effect on the compression in the dam.
With another spindle (image 3, pos. 2 and 3) you can adjust the compression
inside the dam.
The front tins (optional) should have been adjusted in a position to loosen and
level the area directly beneath the bottom of the dam.
Working order: You should build the dams of your asparagus field in order of
building every second dam at first. Afterwards you build the dams between, that
way you avoid getting the tractor and the dam former in a slant.
The speed should have been adapted to the structure of the soil, but it should not
be more than 4-6 km/h.

How to adjust the dam-former:
Adjust the front tins (optional) concentric to the driving track of the tractor.
Adjust the backside dam forming plates approximately to the dimensions desired:
Adjust the desired height of the dam by the spindle (image 3, pos.:6).
Adjust the desired upper dam width by moving the fulcrum, if necessary (image 3,
pos.: 1).
Adjust the bottom dam width. You should pay attention to the sides of the dam not
to be adjusted too steep.
Now build with the dam-former a dam of 5 m length, the dam should not be filled
fully. If this is not the result, you should adjust the supporting wheels longer, until
the result is satisfactory.
When the machine is adjusted in this way, you should turn the supporting wheels
now each one turn higher.
Now you should check the form of the dam again.
A further modification of the dam height has now to happen simultaneously at the
adjustment for the wheels (image 3, pos.:5) and at the spindle for the aperture
(image 3, pos.: 6).
Please mind that an overcrowding inside the machine leads to a higher need of
power and a quicker obsolescence of the sticks.
In this way you build now the dam above the first asparagus line, then the one
above the third asparagus line, then the fifth, and so on: you leave every second
line. After having done like that, you can start to work on the left over lines. (By this
working method you will avoid having different quantities of soil on both sides of
each dam.)
Adjustment for the dams between the ones you made at first:
For the building of the dams between the ones you made first, it might be necessary to
correct the adjustments a few for to get the same height of the dam.

7.3 Reworking of the asparagus dam
During the harvest time reworking or postdamming of the asparagus dam can be
necessary for the purpose of weed control and closing of the insertion holes.
For this purpose the dam former Leofant can be equipped with dam-loose.
Besides, the following is to be followed:
With the help of the provided fixing clips both dam-loose in the crossbeams are
screwed on between the lower hitching plates, whereby working height and
distance of the loose are given by the dam form.
The lateral tine carrier is pivotable, so that the dam-loose can be adapted to the
inclination of the dam flanks.
Fundamental the spring tines must be adjusted so that the upper layer of dry sand
trickles down to the dam sole. The following spike drums mix the dry ground when
raising the dams with damp soil and there results a new more stable dam.
8. Maintenance and care
After the first 10 working hours you absolutely have to check the nuts at the
wheels and - if necessary tighten them again.
The tire pressure has to be checked once a month. (p = 2bar).
Once a year you have to do an oil-change.
You have to do the following maintenance and service workings for to reduce the
obsolescence of the dam-former Leofant:

8.1 Lubrication points
The regular intervals for lubrication and maintenance have to been absolutely
respected. The lubrication points (image 4.1 and 2) and the PTO shaft have to been
lubricated every 20 hours.
Image 4
While re-lubrication there might get some lubricant into the soil, the ground water
or into the feed. Therefore we recommend on principle the using of biodegradable
lubricants!
8.2 Resetting and changing of the stick
The sticks (approx. 350 mm long) are screwed to the both stick-rotors. In case of
approx. 30 mm of obsolescence of the sticks you have to unscrew them at the rotor
and set them on one position further to the outside. After 2 hours of work you should
check and tighten the screws in the rotor in driving direction right to the back, in the
rotor in driving direction left to the front.

8.3 Maintenance of the propulsion
Before the first introduction the oil level must be checked!
The propulsion has to been checked of leakage and filling quantity after 20 hours
of working.
At the front of the dam-former Leofant there is the gearbox, in which you find the
propulsion for the driving and for the rotors.
Every 20 working hours you also have to check this for leakage and filling quantity.
The quantity of the oil is enough, when you can see the oil in the looking glass
while the machine is standing horizontally.
If necessary, fill up with gear oil CARTER SH 320. With use of a tractor with more
than 120 HP, we recommend the use of “CARTER SH 320” High quality oil.
Change the oil once a year.
The filling quantity is 10 –12.5 L at each side.
8.4 In case of longer breaks between using
Clean up the dam-former Leofant, do the lubrication as described in this instruction
manual (see lubrication plan p. 7) and spray with oil.
Front this (optional), back tins and dam forming metals (not on the plastic) have to
been spread with grease after the cleaning.
Damages in the lacquer have to been repaired.
If you have a cardan shaft with slipping clutch, then you have to remove the air
after longer non-using.
