The GMD 9530 RV, an innovation in the KUHN mower range.

The machine offers a different swathing concept compared to mower conditioners equipped with a swath grouper. After being cut, the unconditioned fodder is directly transported by the auger to the center of the mower to be delivered on top of the swath formed by the front unit. This new practice developed as a result of various factors: the search of high ouptut while reducing operating costs, the development of crop intended to produce energy and the evolution of cutting periods on soils limiting passes.

With a working width of 9.10 to 9.50 meters in combination with a 3.10 meters front mower, the GMD 9530 RV is equipped with two OPTIDISC ELITE cutter bar of 8 discs. It's capacity to combine mowing and swathing in one pass reduces the number of operations.

It also features KUHN's renowned technical components, such as the LIFT-CONTROL combined with NON-STOP safety, the mower-unit offset systems and the OPTIDISC ELITE cutter bar fitted on GMD models in the 1030 series.

During transport, the dimensions of 3 metres wide and 4 metres high ensure excellent manoeuvrability. In addition, the position of the swathing augers close to the tractor, results in a limited weight of 3.3 tonnes similar to an FC 9530. The machine is therefore perfectly suited to 200 hp tractors in most conditions.

The GMD 9530 RV perfectly meets the needs of professionals (farms, machinery cooperatives, contractors) looking for performance, quality and profitability.

A robust design for unmatched durability

Suitable for demanding working conditions, the augers and cutter bars are driven separately by cardan shaft and gearbox.

Made to last

The GMD 9530 RV features a 100% mechanical power transmission system.
The swathing augers and cutter bars are driven separately by cardan shaft and gearbox resulting in a high-capacity and very robust machine, even in difficult conditions with heavy, dense fodder. The automatically resetting cam clutches and shear bolts, in the side gearboxes that drive the augers and cutter bar, secure all machine components while ensuring optimum working comfort and efficiency.

Robust materials for intensive use

Designed with two large-diameter swathing augers (Ø500 mm) that rotate at 900 rpm, the GMD 9530 RV provides high work output, even with large fodder volumes.
As standard, these augers are reinforced with Hardox® wearing parts that prevent premature wear and reduce maintenance costs.
The addition of the bolted wear lining prevents premature deterioration and meets high standards in terms of durability, robustness and maintenance cost reduction.

Modular swath delivery

To adapt to different plots and to demonstrate great adaptability, the GMD 9530 RV is equipped as the GMD models in the 1030 series, with the mower-unit offset system which allows in-cab adjustment of the working width from 9.10 to 9.50 metres.
When taking into account the position of the mowing units and the position of the deflector, the user can vary the swath width from 1.60 to 2.20 metres depending on the type of fodder and the harvesting machines.
In order to save the pass of a windrowing equipment, the machine is able to form a swath with all the harvested fodder from a 9.50 metres mowing width in a single pass. Ideal for exploiting the full potential of a baler, chopper and self-propelled loader.
The mower also integrates an in-cab individual management of the hydraulic lifting of the grouper rear hoods placed at the rear of each of the augers. The user thus can choose between a delivery over the whole width or a delivery with a swathing unit raised.
Whole width delivery, also known as wide delivery, promotes fodder drying. With the swathing augers continuing to turn, the fodder is given a "brushed" effect" and is directed towards the centre for easier pick-up with a windrowing equipment, such as the MERGE MAXX.
Finally, by raising the swathing unit on one side, to mow up and down, the mower can deliver 18 metres of cut fodder over 12 metres. This configuration makes for an efficient pick-up with a four-rotor rake.

Simple control of the machine functions

Regarding the control of the machine, the operator can choose between the KFA 12 control box or the new ISOBUS MOWER CONTROL kit.

As standard, the mower is equipped with the KFA 12 box to control all functions from the cab: suspension, switching between transport-work position, lifting of the mowing units, adjusting the offset and lifting the swathing units. The box thus offers an economical solution that is simple and intuitive to use.

As an option, it is possible to control the GMD 9530 RV with the ISOBUS MOWER CONTROL kit created for large-width mowing units. Feel the benefit of a more practical control system, by managing the folding and unfolding sequence, the individual mowing unit management, the offset adjustment, the hectare counter, the suspension adjustment, etc. You can also take advantage of additional automation functions such as headland sequence management or Section Control (TC-SC).
Control is made directly from the ISOBUS terminal already in the tractor or with the KUHN ISOBUS CCI 60, CCI 800 and CCI 1200 solutions. The CCI A3 ISOBUS joystick can also be used to improve ergonomics thanks to the display of icons related to the different functions of the machine.

A machine control system that meets the needs of every user

Compact design

With a width of 3 metres and a height of 4 metres, the compact dimensions of the machine on the road and its limited weight of 3.3 tonnes make it easy to move around. The integration of the swathing augers close to the tractor, limits the overhang and results in a limited weight on the tractor. Thus, in most working conditions, a tractor of around 200 hp is enough.

Renowned equipment for clean mowing

The LIFT-CONTROL suspension system combined with NON-STOP safety protects the machine in case of hitting an obstacle.

Exclusive LIFT CONTROL system combined with NON-STOP safety

Should you have obstacles in your fields that you have forgotten about, the LIFT-CONTROL system combined with NON-STOP safety is there to help you.
In case of hitting an obstacle, the concerned mower unit pivots rearwards around an axis. At this point, oil is transferred, causing an increase in pressure and making the mower unit lighter, which makes it easier to clear the obstacle. The mower then automatically returns to its working position.

For optimum mowing quality, the LIFT-CONTROL hydro-pneumatic accumulator suspension system offers excellent ground following and can be adapted to all conditions.
The appropriate adjustment of the suspension thus limits introducing impurities into the fodder, reduces the cutter bar ground pressure resulting in lower fuel consumption, reduced skid wear and preserved sward.

OPTIDISC ELITE: high performance cutter bar

One of the primary requirements for farmers is to have a high-quality cut in order to save on concentrate in their livestock feed. To achieve this, KUHN has developed the OPTIDISC ELITE cutter bar in partnership with users, to provide the quality you need.
In all situations, whether on hilly plots, in wet conditions or with sticky grass, the cutter bar ensures excellent mowing quality thanks to different disc spacing, large overlap areas and a low mowing angle.
Where the discs diverge (A), spacing is reduced to facilitate the overlap, while it is increased where the discs converge (B) to provide more space for crop to pass through.
At the heart of the cutter bar, high-end components reinforce the reliability and durability of the assembly:

Double-row angular contact ball bearings.
Large-diameter gearwheels in forged steel with 3 cogs engaged.
3-point bearing mounting with long through bolts.

To prevent damage during mowing, a PROTECTADRIVE safety system, exclusive to KUHN, has been designed to cope with obstacles. In case of a violent impact, the shaft holding the disc shears above the bearing thanks to a groove protecting the internal components. In less than 15 minutes, the machine is operational again at reduced repair costs.

The OPTIDISC ELITE cutter bar provides a clean cut

Minimum maintenance

The GMD 9530 RV has been designed to reduce maintenance to a minimum.

The OPTIDISC ELITE cutter bar, lubricated for life, requires no maintenance, ensuring long-lasting reliability without intervention.

The FAST-FIT quick-release knife system allows a replacement in a matter of minutes, minimising downtime during the season. A powerful leaf spring applies constant pressure on the fastener, ensuring excellent knife hold and optimum safety during replacement.

Routine maintenance is mainly limited to a few lubrication points on the transmissions and pivot points, with long service intervals. This saves time and provides peace of mind for demanding users.

Equipment

Sliding deflector

Adjusting the position of the deflector is one of the settings that allows the swath width to vary from 1.6 to 2.20 metres depending on the type of fodder and the harvesting machines.

KFA 12 control box

All GMD 9530 RV functions are easily accessible from the KFA 12 control box in the tractor cab. Its lean design makes it easy to understand, enabling clear and rapid management of the machine.

ISOBUS control provides user comfort and new features.

ISOBUS MOWER CONTROL KIT

As an option, the ISOBUS MOWER CONTROL kit offers the possibility to control additional features such as Section Control or the hectare counter. Simply use an ISOBUS terminal already installed in the tractor or the KUHN CCI 60, CCI 800 and CCI 1200 terminals. The ISOBUS CCI A3 joystick can also be used to view the functions directly on the touchscreen.
