KUHN, the world leader in rotary tedders, continues to provide farmers with Gyrotedders that aid in increasing productivity while reducing losses in the field.

KUHN mounted, semi-mounted or trailed Gyrotedders offer the following benefits:

Easy folding and unfolding

In order to change from the working position to the transport position, the outer rotors are raised manually to the vertical position.

Minimised lift requirement

The compact hitch design considerably reduces the distance from the tractor to
the implement’s centre of gravity. Low horsepower tractors can be used with a
minimum of front ballast. With the tines safely pointed inward the transport width is reduced to 2.17 m (7’1’’).

Pivoting headstock:
true mobility

The pivoting headstock provides flexibility and manoeuvrability.
Even while turning, the tedder is always in line with the cut crop.
When raised, the hitch automatically centres and locks the implement in line with the tractor.

Comfort and safety go
hand in hand

Folding and extending of the outer rotors is controlled hydraulically from the tractor.
Transport locks are also released from the tractor using a release cord.

Multi-purpose wheels

Wheel height adjustment is through an eccentric. The turn of a simple handle alters the angle of the machine to best suit the density and stubble height of the crop.
Wheels are also capable of being turned manually for oblique operation, as at the edges of fields and along hedges.

Rotors pivot by 180°

Once raised, the rotors lock automatically.
For additional security and reduced storage requirements, rotors pivot 180°.
With the tines safely pointed inward the overall transport width is also reduced.

Three swaths in a single pass

With a width of 5 m (16’5”), the GF 5001 MH and T Gyrotedders are recommended for use with a 2 m (6’7”) disc mower where three swaths are tedded without the tractor running over the crop. Two windrows from a 3 to 3.5 m (9’10” to 11’6”) mower conditioner can be tedded by running between the windrows.
The GF 5001 MH and T can also be used to ted two windrows from a 3 m mower.

GF 5001 T/7001 T:
Articulating & Folding frame

The well designed linkage of the frame articulation joints enables the GF 5001 T to follow uneven field contours.
It makes the tedder easy to fold from work to transport and back again while
still maintaining the ability to flex vertically.

For low horsepower tractors

The GF 5001 T, with its drawbar hitch, can be used with very low horsepower tractors, even with tractors without a hydraulic 3-point hitch.
Small farms with old or small tractors can also benefit from the advantages of the
GF 5001 T.

Narrow transport

For transport the two outer rotors of the GF 5001 T are folded towards the rear.
In the transport position the width of the tedder does not exceed 2.80 m (9’2”).
The width is below 3.00 m (9’10’’).

“Pro” tines

Deflectors A prevent crop build up for improved spreading
The uneven strand length B provides improved raking and increased tine service life.

Hydraulic adjustment for oblique operation (MHO only)

The machine can be set to right or left oblique running from the driver’s seat by simply operating the hydraulic control valve.
The exclusive design of this mechanism (fitted with 2 bearings, one of which is a taper roller bearing) provides the system with unequalled reliability.
There is no maintenance or risk of wearinduced play or of the turning shaft seizure.
Total control is available for tedding at the edges of fields or on steep slopes.

6 small diameter rotors: quality tedding

The articulated frame and 6 small diameter rotors ensure the crop is turned over in
its entirety.
Not only is the crop more evenly spread but the reduced speed at which it is
discharged means more gentle handling an reduced nutrient loss in the hay.
The models GF 5801 MH / MHO meet all the criteria required to produce
highly nutritious forage.

Anti-drift stabiliser: for even spreading

The anti-drift stabiliser enables regular crop deposit for a homogeneous drying process.
This device minimises the “wallowing” that would normally occur when a
tedder is operated at high speed or in dense crops.
The tedder tracks smoothly in line with the centre of the tractor. Normal turning and
pivoting of the headstock is not affected.
As standard.

Safe transport

With a very narrow width the GF 5801MH / MHO models are also very
compact in transport. with a width of less than 2.40 m (7’10”).
In addition, a lighting and signalling system is fitted as standard to increase
safety on roads.

“Anti-Drift” stabiliser:
regular windrows for even drying

The GF 6401 and 7601 gyrotedders are fitted with an anti-draft stabiliser with
adjustable setting.
Prevents them from drifting off course at high speed or in very dense crops,
They stay perfectly in line with the tractor and the pivoting headstock’s
manoeuvrability is not affected when turning.

Larger ground contact area

The central carrying rotors are fitted as standard with reinforced wheel columns
and Megaballoon wheels

Ideal for cutting widths of
around 3 m (9’10”)

Fitted with 8 rotors of small diameter each Gyrotedders enable tedding 3 swaths of
a 3 m (9’10’’) disc mower. Quick and easy adjustment of the rotor angle allows for
accurate adjustment and clean pick-up of all types of forage and in any terrain conditions.

MHO version: an exclusive mechanism for adjusting for oblique operation

The wheel shafts are coupled to a hydraulic controlled linkage.
Setting them for oblique operation to the left or right is controlled from the driver’sv seat.
This mechanism, exclusive to Kuhn, is very reliable and is fitted with 2 bearings
on each wheel shaft. No maintenance is required.

Minimum transport width
and standard lighting system

Despite their size, the GF 7601 and GF 8501 are less than 3 m (9’10”) in
width for transport and storage.
Due to their compact dimensions and small overhang, these units can be used with low horsepower tractors.
All controls are operated from the tractor cab.
Furthermore, a full lighting and signalling system is included as standard equipment.

Highly efficient tines

Tine deflectors A prevent crop wrapping for improved crop injection,
The uneven prong B length provides more efficient raking and increased tine
service life.

Transport

The wide track of the rear transport wheels using high floatation tires (ultra-high floatation on the GF 10601 TO) provide these tedders with excellent stability and transportability.
In addition to the compact folding capability for transport, a lighting and signalling
system is fitted as standard equipment.

Oblique tedding keeps
hay in the field

For tedding along the edge of a field and to avoid any risk of throwing any crop
out of the field or onto a fence oblique tedding is provided. Simply operating the
hydraulics and an electric switch in the tractor cab enables all the wheels to be
turned to the left and to the right on the GF 8501 TO and GF 10601 TO
Gyrotedders.

“Mega Balloon” tyres for high floatation

The two central rotors are each equipped with reinforced wheel columns and Mega-Balloon tyres.
The weight distribution of the central section of the frame is then easily
carried and ground pressure is reduced.
This also improves the operation of the semi-mounted Gyrotedders over irregular ground.

Thorough, even, tedding

The articulated frame and small diameter rotors ensure the crop is turned over in its entirety.
Not only is the crop more evenly spread, but the reduced speed at which it is discharged means more gentle handling and reduced nutrient loss in the hay.
Semi-mounted Kuhn Gyrotedders meet all the criteria required to produce
highly nutritious forage.
