4 Use, technical specification and technical description of

the machine

4.1 Use of the machine

The mulcher is meant for mowing grass stands of all kinds of stalky grasses, preferrably
old and dry, on both maintained and unkept sites.
The period most suited for the machine use is outside the growing season, i.e. in the
months of March, at the beginning of April and in the period from the end of August to
November. In these periods the stands are usually dry and the mowing knives are capable of
crushing them into small pieces which need not be removed from the surface. The
recommended height for cutting newly grown up stands is up to 40 cm.

 Engagement width has to be always accommodated to the density of the mown

stand.

The machine can also be used as a mower for park treatment of grass stands with no high
demands for grass stubble quality (flat terrain, low cut, ruts after machine wheels, etc.)

4.2 Technical description of the machine

The machine is based on a rigid frame in which a gear-box is placed with primary worm
gear for machine travel and with claw clutch to be switched on after pressing the machine
travel lever. The secondary gearing onto the axis of wheels is designed as a roller chain. The
wheels have treads with the tractor herringbone pattern which finds employment especially in
sloping terrains. The wheels are equipped with the ball free wheel for easier turning and
machine handling.
Guide wheels with a possibility of mowing height adjustment and side arrestment are
attached to the knife casing which is equipped with a removable front part to be
automatically elevated when the machine enters a dense grass stand.

F-530.1

On the upper part of the frame there is a 4-stroke combustion engine to prime the machine
travel gear through the pin clutch and through the V-belt the mowing knife which is installed
on the knife shaft through the friction clutch. The knife is made of high-quality hardened
steel. The mowing knife drive is to be switched on by the pulley-controlled lever on the
handlebars. A part of the mowing knife is also a safety brake to stop the mowing knives after
the mowing knife drive clutch lever has been released.
The knife with bent ends and blade is installed on the knife shaft through the friction
clutch.
On the tube handlebars whose height can be adjusted in three positions there is a control
lever of the travel gear, a control lever of mowing knife drive gear with brake, and an
accelerator lever to set-up engine speed.
Machine accessories include a slide shoe made of steel tube and a set of swinging and
mixing knives.

5.3 Starting the mowing knife

 When starting the engine, the two levers on the handlebars must be in the off

position.

1. Start the engine. When doing this, follow the instructions presented in the operating
manual for engine use.

2. Set-up maximum engine rotations by accelerator lever on the right hand rail.
(Should the engine be cold, let it warm at maximum speed for about 30 seconds.)

3. Grasp the left handlebar grip. Then press the mowing knife drive gear lever on the
right handlebar grip with your right hand.

 Press the lever slowly up to two thirds of the stroke so that the mowing knife

can start rotating and the engine does not stall.

The start of the mowing knife is accompanied with a partial slippage of the V-belt
and associated phenomena such as whistling, rattling, etc. The phenomenon usually
disappears after the belt has started properly moving.

4. After the mowing knife has started turning, press the lever down to the hand rail and

hold it.

Note: In a new or cold engine, engine stalling may occur at several first mowing
knife drive starts. The phenomenon will disappear after the engine has got warmer. If
the knife drive cannot be started even after the engine has got warm, follow the table
presented in chapter 6.6

for diagnostics.

5.4 Machine travel

The travel gear is connected by the lever on the left hand rail. Press the lever down to
the rail and hold it. The machine starts moving forward.

5.5 Machine stop



Prior to performing any activities in the near vicinity of the machine, switch off
the engine and wait until the mowing knife stops! Always switch the engine off
before leaving the machine.

 Never let the engine running at maximum speed or idling with the mowing

knife drive gear clutch released and with the released clutch of travel wheels
drive gear for a long time! Machine drive components (V-belt, belt pulley,
clutch pulley, etc.) might get damaged!

If you wish to stop the machine travel, release the lever on the left handlebar grip.
The machine travel will stop but the mowing knife is still rotating. The mowing knife
drive will switch off immediately after you have released the lever on the right
handlebar grip. The mowing knife will be stopped by safety brake.

Engine is to be switched off by pushing the lever into the STOP position.

 In the case of any critical situation, release your hold on the handlebars

without any delay. The levers will return to their zero position, the machine
and the mowing knife will come to a stop (while the engine is still running at
adjusted rotations; this is why it is to be switched off by pushing the lever into
the STOP position as soon as possible!)

5.6 Working with the machine

5.6.1 Adjusting the mowing height

Machine parts for adjustment of mowing height are either guide wheels or the slide
shoe. Draw bars which are attached to the guide lines and slide shoe can be arrested in
bushes on the knife casing in three positions (by means of safety pins). This is how the
three mowing heights level can be adjusted (ca. 3-5-10 cm).

Adjustment procedure:

1. Grasp the frame of guide wheels with one hand at the place where the tube of the
wheel frame bends (or the slide shoe in the middle of the slide shoe transversal part)
and slightly lift the machine so that pins with lock can be pulled out.

2. Tip the pin lock with the other hand and remove the pin from the hole.

3. By elevating or lowering the machine the draw bar is displaced into another
adjustment position.

4. Install the pins with the lock back into the holes and clap the lock in.

Positions of mowing height adjustment (see Fig. 4 – bottom right

):

Position 1 – Stubble height ca. 10 cm
Position 2 – Stubble height ca. 5 cm
Position 3 – Stubble height ca. 3 cm

5.6.2 Mowing of grass stands



Prior to the machine use, the stand must be cleared of solid bodies such as stones,
wires, loose construction debris, etc., which could be flung or might otherwise
damage the machine. Should these be impossible to remove, pass the places by.

 Mowing engagement width has to be at all times accommodated to stand density!

 In dense or high grass stands it is always necessary that the guide wheels or slide

shoe are adjusted at the highest position!

Adjust the engine on maximum speed, let the mowing knife rotate at maximum speed
(see chapter 5.3

) and get the machine into motion (see chapter 5.4) against the stand to be
cut. If the stand is too dense, grown through, rotten or lodged, the machine engagement
width must be reduced accordingly so that the rotations of the mowing knife are not being
excessively reduced and the cutting quality impaired.

If the space of the casing of mowing knives gets choked, there are three possibilities for
a solution:

a) Engine loosing speed: cutting height to be adjusted higher (see chapter 5.6.1

) and

engagement width to be reduced;

b) Engine markedly loosing speed but not stalling: machine travel to be switched off

immediately (lever on the left handrail); drive in reverse gear just a bit with a
simultaneous slight elevation of the machine front (by pushing down on the handlebar

Draw bar to adjust the

handrails). The casing space will do itself a partial clearance of excessive grass matter.
Then drive the machine against the stand again (see chapter 5.4

).

 Be very careful while driving in reverse with the machine!

c) Engine loosing speed and stalling: release the both levers on the handlebars, lift the

machine front part by pushing down on the handlebars and drive a bit in reverse. Clear
the mowing knife casing space and spread the cut grass across the ground. Start the
engine, switch on the knife drive (see chapter 5.3) and once again drive the machine
against the stand (see chapter 5.4).

 Engine must always be switched off when clearing the knife casing space.

 Tilt the machine always only backwards on the handlebars. Be very careful

while moving in the space beneath the lifted machine! Secure the machine
against motion!

 Be very careful while cleaning the space beneath the casing. Mowing knife

blades are sharp. Your hands should be wearing protective gloves or you can
also use a fitted piece of branch etc.

5.6.3 Arrestment of guide wheel suspensions

In order to better guide the machine while driving along the countour line on slope, the
susoensions of guide wheels can be arrested in the position which is parallel to the
longitudinal axis of the machine. Insert the safety lock pins into holes in wheel suspension
bushes on the frame of guide wheels and clap the locks on the pins in. If not using the
arrestment, place the pins with locks onto an oval partition on the machine frame rear part.

Figure 5: Arrestment of guide wheels

5.7 Machine accessories

5.7.1 Slide shoe and its assembly

Slide shoe can be used instead of guide wheels to guide the machine in uneven
terrains. After you have dismounted the guide wheels (reverse procedure as in chapter

5.1, paragraph 4), mount the slide shoes as follows:

1. Insert draw bars which are part of the slide shoe into draw bar bushes on the knife

casing and arrest them by using the pins with locks.

2. Fasten the slide shoe to the knife casing by means of slide shoe studs with flat

washers and self-locking nuts.

Figure 6: Slide shoe assembly

5.7.2 Swinging and mixing knife complement

The complement can be replaced with the standard assembly of “Flat knife 52 cm“.
It is used at cutting the grass stands of lower densities with a higher proportion of thick­walled plants or self-seeded tree species up to a max. diameter of 1 cm. Knife
complement assembly onto the shaft see chapter 6.3

.

6 Maintenance, care and storage

To ensure a long-term satisfaction with our product, it must be given proper care and
maintenance. Regular maintenance of the machine will prevent its early wear ensuring
at the same time a correct functioning of all its parts.

Follow all instructions for intervals of machine maintenance and adjustment. It is
advices that you keep records on the number of machine working hours and on the
conditions in which the machine was working (for service purposes). Similarly as the
current maintenance, the after-season maintenance should be entrusted to one of our
authorized service workshops.

 Regarding the machine weight, maintenance and adjustment are to be done by

two persons.

The gearing works in oil bath. Oil condition should be checked once a month (oil
plugs see Fig. 7).
Minimum classification of gear oil should be GL-4, GL-5 to API or 90 or 80W-90 to
SAE.
Oil replacement in a new machine is to be made after the first 5 hours of operation
and then after 100 working hours or after the end of the season. This will ensure that
the gears will not suffer excessive wear. The exchange interval can be extended up to
130 hours (the running-in time of 5 hours must be observed) in oils with higher
classifications (API GL-5, SAE 80W-90).
Czech oils fully meeting the requirements are MOGUL TRANS 90 or MOGUL
TRANS 80W-90.
Oil replacement should be made when the box is warm, oil can be drained easily.

1. Clean around the oil plugs. Underlay the machine and secure it so that a space is

created under the machine for a vessel to collect oil.

2. Loosen the pour-in plug on the rear wall of the box and the drain plug in the bottom

of the gearbox (spanner No. 19).

3. After the oil has been drained, screw back the drain plug in the bottom of the box.

Fill the gearbox with the new oil (it is adviced to use a funnel with flexible tubing).
Oil level should reach to the lower edge of the hole. Then screw the pour-in plug
back. If the seals under the plugs are damaged, replace them with new ones.

6.2 Tightening of bolted connections

Do pay attention to properly tightened bolted connections. Check tightening of the bolt
fastening the working knife on the shaft before any machine use. In the swinging knives,
check also the bolted connection of rotary blades with the knife holder.

6.3 Replacement and sharpening of working knife

If the working knife cutting edges show wear or a knife damage results in machine
vibrations, the cutting edges must be renewed or knives replaced.

 The machine must be standing on a firm support plate and must be secured so that

the knife can be easily accessible and an unexpected spontaneous machine motion
cannot occur.

 Be very careful at knife disassembly. The knife cutting edges are sharp! Protect

your hands with protective gloves.

 The engine must be switched off and the cable end connector to spark plug

disconnected!

Replacement procedure is as follows (always work with a helping hand):
a) Insert the auxiliar wrench into holes in the friction lamella and hold the drive shaft so that

it does not turn; loosen the bolt by using barrel spanner No. 16).

b) Take the knife out, plane the blade and sharpen cutting edges. Inclination of the

sharpened blade should be 25° with respect to the lower plane of the knife. The knife has
to be properly balanced even after the sharpening; therefore, the material loss should be
identical when sharpening the two cutting edges.

c) Mount the knife back at its place. The order of packing pieces as in the figure should be

observed in order to ensure correct functioning of the friction clutch.

d) Tighten the bolt by using tightening moment 45 N.m.

 Should there be excessive vibrations occurring on the machine handlebars after the

assembly, it is absolutely necessary to balance the knife once again!

Note

: Manufacturer does not answer for damages caused by the machine if the knives were
repaired by unskilled persons without the use of the original spare parts. The spare
“Complete knife 52 cm“ is supplied as one assembly (with respect to the fact that the user
cannot guarantee correct replacement of swinging knives and their safe attachment to knife
holder). Authorized service shops VARI can also make a replacement of the two swinging
knives with the whole bolted connection (see position 4 in the table “Swinging and mixing
knife“ on page ...) onto the original knife holder.

6.4 V-belt replacement and adjustment of tension pulley

The V-belt should be replaced according to its wear (cracked sides, torn belt, sides worn
out down to belt carrier fibres, belt pulled out of shape) or after about 200 hours of operation
at the maximum. In this machine, the belt stretched to maximum is considered a belt in which
the distance between the internal belt surfaces is lesser than 7 mm (with the pressed lever of
mowing knife drive clutch). The replacement procedure is as follows:
a) Drain petrol from the engine tank. Dismount the accelerator lever (2x spanner No. 8)

from the handlebars. Bowden cable should never be dismounted from the control on the
engine!

b) Unscrew three safety nuts (spanner No. 13) on the engine flange and pull the engine out

from the machine frame upwards. Never use force to pull the engine from the frame!

 Never put the engine on the side. Oil might get into the exhaust or into the air

cleaner. The best engine seating is with the lower flange dwelling on two lintels
which are at least 7 cm high.

c) Dismount the V-belt casing (spanner No. 8, spanner No. 10). Dismount the bolt with nut

in front of the driven belt pulley (see Fig. 8.3) (spanner No. 10). Remove the old V-belt
and replace it with a new one.V-belt marking is GATES A45 BareBack.. It is also
possible to use an equivalent V-belt made by other manufacturers at a size of A13x1150
Li (Li=internal length). However, the belt must be made without rubber on belt sides!
Only this belt model will guarantee that there will be no belt extension and that the knife
drive start will be continuous at engaging the clutch.

 Should a different belt model be used, the machine manufacturer does not bear any

liability for the correct and full functioning of the gear!

d) Put the engine back in place. Pins on the belt pulley must fall into holes in the driven part

of the coupling mounted on the gearbox. Bolt the engine with three safety nuts with flat

washers and screw the accelerator lever back onto the handlebars.
e) Install the V-belt into the groove in the belt pulley on the engine.
f) Check the operation of the tightening pulley and adjustment of guide lamination. With

the lever on the right handlebar grip being completely pressed down, the pulley must

ensure a sufficient belt tension (spring on the cable being extended by about 10 mm as

compared with the normal loose condition). Possible corrections are to be made by means

of the adjustment bolt No. 1 (see Fig. 12). With the lever switched off, the pulley must be

inclined away from the longitudinal machine axis by 0 - 5° (at maximum) = with the belt

convex side being approx. 1.5 – 2.0 cm from the bottom of the tightening pulley (see Fig.

11) and the cable in the Bowden of the tension pulley must exhibit no slackness. In the

case that the adjustment bolt is completely screwed out and it is necessary to tighten the

V-belt, the spring on the cable can be hooked into the front hole on the arm of the

tightening pulley (see Fig. 11 bottom, note: this connection can be used already from the

manufacturer) and the belt tension can be adjusted once again. Guide lamination on the

right side of the machine must be parallel to the belt and at a maximum distance of 1 – 2

mm from the belt convex side.
g) Mount the bolt back in front of the driven belt pulley and plastic casing of the belt.

 If the gearbox is dismounted from the machine frame, it is necessary to ensure axial

alignment of gearbox shafts and engine at the reverse assembly. This operation

should therefore be entrusted to an authorized service shop which has to have

available an original and manufacturer-approved centring fixture.

Figure 11: Adjustment of tightening pulley and maximum extension of V-belt

6.5 Setting-up litz wires of pulley, brake and machine travel gear

clutch

In order to guarantee low operating forces on levers which control drive switching, it is
adviceable to lubricate cables in Bowdens at least 2x during the season with some oil
available in atomiser (e.g. SILKAL, MD Spray, WD40). Correct functioning of the machine
also requires correct adjustment of drive controls.

The cable in the brake Bowden must always exhibit slight slackness (with the mowing
disk drive clutch lever and brake released) so that the brake performance is sufficient.
The cables in the pulley Bowden and in the Bowden of machine travel gear clutch must be
without slackness, slightly tense.

Safety nuts in all adjustment bolts should be tightened by using two spanners No. 10 or
No. 9. If there is no more step to be used in the adjustment bolt, it is possible to displace the
hook on the cable into another hole in the metal sheet lever on the handlebars (or on the
travel gear clutch lever on the gearbox and on the arm of the tightening pulley, see Figure 11
bottom) so that the pre-stress of cables can once again be regulated by the adjustment bolt.

6.9 Washing and cleaning of the machine

 At cleaning and washing the machine, proceed to observe valid regulations and laws

on the protection of water courses and other water resources against pollution or
contamination with chemical substances.

 Never wash the engine with a stream of water! Electric equipment might fail when

starting the engine.

All dirt, debris and plant residues should be removed from the machine after the end of
the season. Check the intactness of the working knife, grind the knife cutting edges (or
replace the knife if necessary) and conserve the knife with the conservation oil. The travel
wheels should be dismounted from the axle once in a season, cleaned and the hub inside
filled with a new filling of plastic lubricant.

 The engine has to be switched off and the cable termination to the spark plug

disconnected!

Wheel disassembly, lubrication and assembly procedure:

a) Underlay the machine so that the wheels can freely turn. The machine must be secured

against spontaneous motion.

F-530.1

25

b) Take out the split pin and screw off the slotted nut by using spanner No. 24. Remove the

wheel from the axis.

c) Clean the wheel hub inside, wheel hub flange with balls and free wheel from impurities

and old grease.

d) Fill the hub inside with new grease (e.g. for water pumps) lubricating at the same time

also the flange with balls and free wheel surfaces.

e) Slide the free wheel on the wheel axis. The pin driven into the wheel axis must lean

against the inclined surface on the free wheel (see Fig. 13). Put the wheel onto the axis,
screw the nut to the stop; then release it by one split pin groove and secure the connection
with a new split pin. The wheel must freely turn with no great axial clearance.

f) Check of correct free wheel assembly: Press the machine travel gear clutch lever, turn the

driving wheel by hand in the direction of forward travel. The free wheel must be clicking.

Figure 13: Free wheel (on the left wheel)

6.10 Storage

1. Prior to a longer storage, clean the machine from all impurities, debris and plant residues.
Repair the damaged places on the painted machine parts, particularly inside the knife
casing.

2. Conserve the mowing knife if the machine is to be put out of operation for a longer time.

3. Prevent the access of unauthorized persons to the machine.

4. Protect the machine from weather impacts; don’t use the air-tight protection due to a

possible increased corrosion under it.

6.11 Liquidation of packaging and machine after service life

expiration
