HR4004D-4504D

KN208JGB_C

Power harrow

Available as spare parts:

Long blade (special for potatoes):

• Standard left and right blade.
• Left and right DURAKUHN blade.

5.3.3 Rollers

The roller is used as a protection device at
the rear of the machine. It must never be
removed for work.

The roller is an essential element of the harrow and
has the following 4 functions:

• Set and control the working depth.
• To pack the soil evenly behind the rotors and

create an optimum seedbed.

• To increase seedbed crumbling and clod break-

up.

• To improve seedbed levelling.

The machines are factory fitted with one of the
following rollers:



Maxicrumbler roller

HR4004D / HR4504D

The Maxicrumbler roller is adapted to dry or slightly
wet soils.

This equipment is not recommended when the
power harrow is used in combination with a seed
drill.
