5. Construction features
The LIPCO Reversing Harrow, when connected to any type of
engine-driven machine from 7.5 to 9.5 kW, is capable of tilling and
levelling the ground in a single operation, thus preparing it for
seeding. Its outstanding feature is that stones, clods, old lawn, etc.
are dug into the ground.
As can be seen in the figure, the LIPCO Reversing Harrow is
equipped with a grid roller, which makes it possible to adjust the
working depth of the cutter and to ram the earth. (Fig. 1 Ref. A) The
fine pulverization of the earth is achieved by means of the rake (Fig.
1 Ref. B).
The machine is also equipped with a lateral roller adjustment,
enabling to work right to the edge, for example on path borders.
The LIPCO Reversing Harrow is equipped with an overload coupling,
a so-called star ratchet (Fig. 2). This will limit the torque in case of
overload. The noise produced in this process serves as warning
signal.
Attention! When the rattling noise of the locking body is heard,
the power takeoff shaft has to be turned off!

8. Connection to the engine driven machine
Before attaching the machine flange (Fig. 4, Ref. A) corresponding to
the type of engine-driven machine you have, it is recommended
spreading grease on the outer diameter of the machine hub (Fig. 4,
Ref. B). Then insert the flange with its two threaded pins (Fig. 4, Ref.
C) and the two lock nuts. To attach the flange to the hub, proceed as
follows:
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 the toothed wheel work of the connecting shaft
engages correctly with the power takeoff shaft of the engine-
driven machine and the flange has a centred contact with the
engine-driven machine. Then secure the connection between the
engine-driven machine and the unit.
Before commencing work, lubricate drive flange on the lubricating
nipple (Fig. 4, Ref. E)!

Check the level of lubricant in the chain drive via the
corresponding plug (Fig. 11). This operation must be carried out,
when the machine has already been running for a few minutes,
and the grease has warmed up and become 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).
