2.0 GENERAL DESCRIPTION
The Verti-Knife is a processing machine for cutting through a grass layer.
FIRST INSTALLATION – TAKING THE MACHINE OFF THE PALLET
3
12
Figure 6
The machine is placed on the pallet under an angle. To remove the pallet and to place the
machine horizontally on the ground, take the following steps (see Figure 6):
!! NEVER crawl under the machine !!
1. Attach a cable to the upper 3-point (1) and the lifting point (2) at both sides of the
machine.
!! Make sure that the cable/crane/lift can hoist minimum 500 kg (1100 lbs) !!
2. Lift the machine off the pallet (3) and pull the pallet from under the machine.
3. Put the adjustable legs in the lowest position.
4. Lower the machine controlled and calmly until it stands completely on the ground.
!! Careful: Keep your distance; the machine can slide !!
5. Remove the cable.
6. Connect the machine to the tractor (please refer to Chapter 4.0).

11
3.0 PREPARING THE MACHINE
Figure 7
!! Make sure that the Verti-Knife®stands firmly on the ground and cannot
sink or slide BEFORE YOU PREPARE THE MACHINE !!
The machine can ready to use as soon as it is taken off the pallet.
The machine can be made heavier by filling the container with sand or gravel, for example.

12
4.0 ATTACHING THE MACHINE TO THE TRACTOR
Checking procedure before starting to attach the Verti-Knife®:
 Check the Verti-Knife®for visually discernable damage
and repair this if safe operation of the machine is no
longer guaranteed.
 Check whether all the nuts and bolts are tight.
 Check whether all safety stickers are present on the
machine and are not damaged.
NEVER use the machine without these items.

3 1
Figure 8
The Verti-Knife®can be attached to the tractor by means of the 3-point attachment.
The procedure is as follows (see Figure 8):
1. Remove the locking pins (1 & 2) and the pins (3 & 4).
2. Drive the tractor carefully backwards so that the lower connecting
arms (5) can be attached to the frame.
!! Make sure that the tractor is blocked well and cannot move on
its own accord !!
!! Switch off the tractor before descending !!
3. Using the locking pins (1) and the pins (3), connect the lower
connecting arms (5) with the bottom 3-point connection located on the
frame.
4. Set the stabilizer of the tractor to 100 mm lateral stroke.
5. Mount the top rod (6) of your tractor and turn it outward until it reaches
the same height as the 3-point stop connection of the Verti-Knife®.
6. Connect the top rod (6) to the frame with the pin (4); secure the pin (4)
with the supplied locking pin.
7. Turn the top rod (6) inwards so that it becomes pressurized.
!! Make sure that all securing pins are locked before lifting the
Verti-Knife® !!

13
5.0 ADJUSTING THE WORKING DEPTH
The working depth of the Verti-Knife®can be adjusted by turning the spindles (1) at
the backside of the machine (Figure 9).
4
Figure 9
!! Make sure that the tractor is blocked well and cannot move on
its own accord !!
!! Switch off the tractor before descending !!
The start procedure is as follows:
1. Lift the machine so that it hangs freely above the ground.
2. Adjust the spindles (1) by tipping up the locking clamps at the topside
and turning the spindles (1) inward or outward.
!! See the technical data for adjusting the machine to the
maximum working depth !!
3. Adjust both sides of the machine at the same depth so that all knives
enter the ground at the same depth. For this purpose, use the
indicator strip (3) and the indication stickers that are in back of it.
4. Fasten the spindles by tipping down the locking clamps (2) at the
topside of the spindles.
5. Lower the machine onto the ground.
6. Adjust the machine horizontally by turning the top rod (4) of the tractor
inward or outward.
NEVER adjust the machine in such a way that it could damage the subsoil.

14
6.0 DRIVING SPEED
Theoretically the driving speed of the Verti-Knife®is unlimited. However, in practice you
should adjust the maximum speed to the ground that should be treated, the knife adjustment
and the type of tractor that moves the Verti-Knife®.
Too high speed can cause needless damage to the machine.
7.0 USING THE VERTI-KNIFE®
Before using the Verti-Knife®in a location, you should check the following items:
1. Are there loose objects in the field? First remove these objects.
2. Are there slopes? The maximum slope is 20 degrees for the Verti-Knife®.
Always go from top to bottom.
3. Are there cables/pipes buried in the ground? If so, determine their depth and adjust the
working depth of the machine to 60% of the depth of the cables/pipes.
4. Are there hard objects in the ground? Adjust the working depth.
5. Is there danger of flying objects (e.g., golf balls) that distract the attention of the driver? If
so, the Verti-Knife®CANNOT be used.
6. Is there danger of sinking/sliding away? If so, postpone using the Verti-Knife®.
7. If the soil is frozen or very wet, postpone the activities until conditions improve.
8.0 START/STOP PROCEDURE
The start procedure is VERY important. If this procedure is not executed as described below,
it might result in serious damage to the Verti-Knife®.
Figure 10
The start procedure is as follows (Figure 10):
1. Have a good look at the Verti-Knife®and see whether all components function properly.
!! If not, first solve the problems before using the Verti-Knife® !!
2. Connect the Verti-Knife®to the tractor as described in Chapter 4.0.
3. Lift the Verti-Knife®.
4. Drive to the spot where the processing should take place.
5. Adjust the working depth as described in Chapter 5.

15
6. Engage the tractor in the correct gear.
7. Start driving the tractor and lower the Verti-Knife®smoothly into the ground.
8. Accelerate to the optimal speed for the surface that should be processed.
Work in straight lines; working in bends causes damage to the surface that
should be processed.
Stopping occurs as follows:
1. Lower the driving speed of the tractor.
2. While driving at low speed in a straight line, lift the Verti-Knife®out of
the ground.
If the Verti-Knife®is lifted in a bend or while standing still, the ground
might get damaged.
3. Go to the next location and start all over again as described in this
chapter.
9.0 TRANSPORTING THE VERTI-KNIFE®
The user is responsible for transporting the Verti-Knife®in back of the tractor over public
roads. Verify the national legislation regarding the regulations.
On open fields while the machine is raised, the maximum permitted speed is 12 km/h (7.5
mph) due to the weight of the Verti-Knife®.
A higher speed can be dangerous for the driver and/or the public and can even damage the
machine.
!! When the machine is raised off the ground, the front axle of the tractor has
to support minimum 20% of its weight. !!

16

2. Put the adjustable front and rear legs in the lowest position (A).
3. Lower the Verti-Knife®controlled and calmly until it stands completely on the ground.
!! Make sure that the tractor is blocked well and cannot move on its own
accord !!
!! Switch off the tractor before descending !!
!! Make sure that the Verti-Knife®stands firmly on the ground and is
blocked against sliding before descending from the tractor !!
4. Release the top rod (1).
5. Take the locking pin (2) out of the pins (3) and pull the locking pin out of the top rod
connection.
6. Take the locking pins (4) out of the pins (5) and pull the locking pins out of the Verti-
Knife®frame so that the bottom lifting arms of the tractor are released.
