10.Connection to the engine-driven machine
Note:
In standard version, reversing harrow is equipped with rotation
gear.
As UF 70 reversing harrow is also available with an anti-clockwise
gear (version UF 70 L), make sure, when attaching reversing harrow
to the engine-driven machine, that both directions of rotation are
identical.
The direction of rotation of the reversing harrow must correspond to
the direction of rotation of the engine-driven machine, otherwise
malfunctions / damages will occur.
•Before attaching the machine-flange (Fig. 6) corresponding to the
type of engine-driven machine you have, it is recommended
spreading grease on the outer diameter of the machine hub (Fig.
6, Ref. B). Then insert the flange with its two threaded pins (Fig. 6,
Ref. C) and the two lock nuts. To attach the flange to the hub,
proceed as follows:
Fig. 6
•Screw the threaded pins in as far as possible and then unscrew
them by one turn. Tighten the lock nuts. After this operation, make
sure that the flange oscillates freely without squeezing or blocking.
•After having greased the connecting shaft (Fig. 4, Ref. D), insert it
on the machine shaft of the Reversing Harrow. When these steps
are complete, move the engine-driven machine close to the unit.
Ensure that the gearing of the connecting shaft engages correctly

12.Working instruction (Release of overload clutch)
Attention:
Note
the working direction!
Working against the specified working direction can cause heavy
damages on the machine, for which LIPCO denies any
responsibility!
Working direction –pulling,
See direction of arrow
Fig. 9
•The blades are by their shape and cutting position designed for
this working direction.
•Working against the prescribed working direction leads to an
overload of the cutters and drive, and can thus cause damage to
the machine.
•Simultaneously with non-observing the working direction, the
harrowing result will get worse.
•The LIPCO Reversing Harrow is equipped with an overload clutch
(star ratchet), which is pre-set at the factory. Do not change the
setting of the overload clutch.
The overload torque depends on the size of the machine.

Troubleshooting:
If there is an overload –indicated by a ratcheting noise –turn off
the PTO immediately.
An overload can happen by:
- Too big stones in working area
- Other obstacles
- Jammed part in cutter area like stone, branch, root
Remove obstacle carefully from working area of turned-off
machine.
If there are generally too big stones or other obstacles in the
working area, then remove them manually prior to starting any work
with the LIPCO Reversing Harrow.

•Check the oil level in the angular gear (Fig. 8). Oil level 2-3 cm in
horizontal gear drive position. Make the first oil change after 30 to
50 operating hours. Further oil changes after every 200 operating
hours or once a year. Use gear oil SAE 90. (Amount of oil 0.3 L)
Oil filler neck to check oil level in

•Lubricate the drive flange once a month via the lubricating nipple
provided especially for this purpose and then turned once to allow
the grease to become distributed!
•Make sure it runs smoothly.
•Remove drive flange once a year, clean and regrease it.
•Lubricate the overload coupling (star ratchet) and universal joint
shaft of the drive every 8 operating hours and after a longer
standstill! (Fig. 12)
Protective hood opened.
Lubricating nipple (3x)

•Check the level of lubricant in the chain drive via the corresponding
plug (Fig. 11). Make the check, when the machine has already
been running for a few minutes. This ensures that the grease has
warmed up and is distributed evenly. Then check the grease level
with a dipstick (grease level should be at least 5 cm, measured
from the lowest point of the chain case to ensure that the chain is
always sufficiently lubricated).
