7. Design Features
The LIPCO Reversing Harrow Type UFD is the only machine that,
when connected to any type of engine-driven machine from 13 to 38
kW, is capable of tilling, levelling, and preparing the earth for seeding
in a single operation. Its outstanding feature is that stones, clods, old
lawn, etc. are dug into the ground.
As a standard, the LIPCO Reversing Harrow is equipped with an
overload coupling, a so-called sliding clutch. Sliding clutches limit
short-term torque peaks during operation, e.g. when a stone gets
jammed. The friction clutch is adjustable; to do so, remove the
protective hood (Fig. 1). Increasing or reducing the spring force will
adjust the friction clutch (Fig. 2). Ensure that all screws are evenly
tightened.
