4 Belts
Original spare
parts belts
The original PTO
belt is designed to
operate, even if the
pulleys are moving
up and down and
are tilting at the
same time
Most of the belts at
the machine have
tension rollers,
actuating from the
outside of the belt.
This means the the
belt has to bend
both inwards and
outwards during the
operation.
The original belts
are carefully
selected to give the
lowest noise
increment to the
machine during
operation.

Remarks
The implement follows
the ground which
involves that its pulley
is constant moving.
To resist the excessive
operating conditions,
the original belts are
made of fibre
reinforced rubber.
All original belts which
operate with tension
rollers actuating from
the outside have
reinforcements. The
reinforcement is
special designed for
the actual case.
Depending on the
function of the belt, any
of the following belt
types are itemised:
• Wrapped
• Non-friction
• Raw-edge
