3. Generality
3.1 Generalities on tine
- Robust design with no grease nipple at all = no
maintenance
- The tine made up of two working angles ensures
effective penetration and ensures efficient and
homogeneous mixing.
- The height under beam clearance of 870mm is ensuring
blockage free operation

3. Generality
3.2 Tine flexibility
- All parts from the tine are heat treated
- The KVERNELAND tubular tine allows flexibility and a
light weight.
- High vibration capacity providing intensive crumbling
effect.
- Design made out of a tube enabling the C shank to
move side ways +/- 14 cm with the short tine, and +/-
20 cm with the long tine.
- Complete Non-Stop tine, without share, is only 35 kg

7
3. Generality
3.3 Tine holder
- The tine holder is a patented system. The U of the holder is
clamped to the frame by a single bolt
-To ensure a good tightening (pinch) and to maintain the
elements in place on the frame, the torque must be
maintained at 600 Nm.
- This U is formed in a plate of 100mm wide; it provides a
good base of the tine on the tube.
- The light tine can be easily removed to adapt the machine to
the working conditions or tractor available.

KK089680 640 kg O
- The shear bolt leg design
is providing a Vibromat
effect
- A 2T pressure is applied at
the breaking point to
ensure a clean breaking of
the bolt
- the tine being made from
a tube is flexible enough
to allow the point to trip 10
cm back before the bolt
breaks.

5.1 Before transport
Without parallel lifting With parallel lifting
- Put the spindle in a fixed hole of the telescopic bar to lock
during the transport. The operation is facilitated by using
the second pin provided.
- Set the grey bush so as to have the frame horizontal in
transport position, raise the machine and place the
second pin in fixe hole.
- Raise the machine completely then fold it.
- Make sure the automatic hook is securely locked.
-Fix the safety fork on the cylinder rod.
- Lower the machine to keep only about 2 to 3 cm distance
between the safety fork and the cylinder.
Always close the hydraulic safety valve before transport. Never lift completely the machine on transport to
allow a suspension effect by the accumulator.
- Raise the machine completely then fold it using the
hydraulic functions.
- Make sure the automatic hook is securely locked.
- Fix the 2 safety forks on the 2 cylinders rod.
- Lower the machine to keep only about 2 to 3 cm between
the safety fork and the rear cylinder. Put the fork in contact
to the cylinder at the front.
Always close the hydraulic safety valve before transport.
