The KUHN GMD 9530 RV delivers true two-in-one versatility by combining high-capacity disc mowing with an integrated auger merging system. Mow and spread crop across the full cutting width for faster drydown, or engage the augers to place forage into a clean, uniform windrow for efficient pickup. This flexible design allows operators to adapt quickly to changing crop conditions and harvesting goals.

Built to excel in heavy, high-yielding forage, the GMD 9530 RV utilizes a 100% mechanical drive system that provides reliable power transfer, exceptional durability and smooth crop flow. Large-diameter augers and a straightforward mechanical design make it easy to handle dense crops while reducing the horsepower demands compared to belt merging systems.

Where Performance Meets Practical

2-In-1 Mowing and Merging

Featuring two large-diameter 20-inch (50 cm) auger mergers rotating at 900 rpm, the GMD 9530 RV is built to handle high forage volumes while maintaining exceptional productivity. Reinforced with durable Hardox® wear components, the augers are engineered to resist premature wear, helping reduce maintenance costs and maximize uptime.

For added versatility in dry hay conditions, the machine can be operated solely as a mower. A rear pivoting hood allows operators to spread the crop evenly across the cutting width, promoting faster drydown and improving harvesting efficiency.

Built for Heavy Forages

Engineered to perform in demanding conditions, the GMD 9530 RV delivers the durability and reliability needed for heavy, dense forage crops. Its 100% mechanical power transmission and heavy-duty gearboxes ensure consistent performance, while shear-bolt protection helps safeguard key components from overloads.

Lift-Control Hydropneumatic Suspension

The Lift-Control® system combines a compact, lightweight design with advanced hydropneumatic suspension to deliver superior performance in the field. Unlike traditional passive systems, this dynamic design actively responds to changing conditions, automatically adjusting cutterbar weight by using the forces acting on it. As ground pressure increases, the system lightens the cutterbar to maintain optimal performance.

Easy to adjust and operate, Lift-Control ensures consistent ground pressure, excellent terrain following, and reduced wear on machine components. The result is cleaner forage with less ash and soil contamination, improved turf protection, and reliable non-stop breakaway performance.

Key benefits include:

Consistent ground pressure
Superior terrain following
Reduced soil and ash incorporation
Minimized turf damage
Lower component wear
Non-stop breakaway protection

Simple or Advanced Control

The easy‑to‑use KFA 12 control box offers numerous in-cab adjustments, including machine folding/unfolding, cutting unit lifting and shield adjustment. Step up to optional full ISOBUS automation for additional functionality, such as headland sequences, section control, and diagnostics, improving comfort and overall operating efficiency.

Optidisc® Cutterbar: A Clean and Consistent Cut

Lubed-For-Life Optidisc® Cutterbar

The Optidisc Elite cutterbars provide a flat, streamlined profile so that soil and crop residue do not accumulate and material flows smoothly, even in heavy, difficult crop conditions. These mowers come standard with the Fast-Fit® quick release knife system. Optidisc cutterbars are designed and tested with a zero oil change interval. The highly-polished gears and synthetic gear oil ensure that this system does not require any regular internal maintenance, eliminating the need for cutterbar oil changes throughout the life of the machine.

Differential Disc Spacing

The innovative design of the Optidisc cutterbar offers exclusive differential disc spacing.

1. Less Distance for a Clean Cut
Narrower spacing at diverging discs provides greater knife overlap, which results in a clean cut, even when the grass is short or light.

2. More Distance for Easy Crop Passage
Wider spacing at converging discs provides more space for the crop to pass. Cut crop is quickly carried away from the cutting area, greatly improving the cut quality.

Standard Fast-Fit® Knives

The Fast-Fit quick-release knife system allows an operator to rapidly change out cutting knives with the use of a simple tool, yet still retain optimum cut quality and knife life. With Fast-Fit, an operator can achieve up to 50% time savings over a standard system.

Protectadrive® Disc Bearing Stations

Protectadrive^® Protection
Every minute saved during the hay season is precious. Ultimate protection, from the externally removable Protectadrive disc bearing stations, provides maximum reliability and quick service. In the event of an impact between a disc and an obstacle, the shaft holding the disc can shear just above the bearing. This is thanks to its carefully dimensioned shear groove. As a result, the gear teeth are protected.

Extra Rigidity Where It Counts
Disc bearing stations are attached by bolts that pass through the entire cutterbar. This is an exceptionally strong and secure attachment with no risk of mount being torn out of the cutterbar in case of shocks. The disc drive pinion is held precisely in place, all resulting in excellent reliability and reduced maintenance costs.

Gear-to-Gear Power Transmission
Gear-to-gear power transmission, a staple of all KUHN disc mowers, allows for maximum power to be transferred through all gears in the cutterbar. Unlike other gear cutterbars, equal sized gears throughout reduces torque on the gear teeth and leads to unsurpassed reliability and longevity.

Ultimate Protection in the Field

Active Non-Stop Breakaway

No farmer can afford to damage their mower during the peak of the season because of an unnoticed obstacle or maneuvering error. On the new rear units, the mowing unit pivots rearward around the bracing pin when hitting and obstacle. In this moment, oil is transferred toward the suspension cylinder. The resulting pressure increase facilitates the mowing unit raising to clear the obstruction. Return to the initial working position is carried out nonstop.

FlexProtect™: Flexible Protection

FlexProtect™ side shields protect the edges of the machine from damage when driving along field edges or near obstacles. The side shields, made of high-density polythene material, will bend without breaking or damaging the mower. The material then returns back its original shape. When operator’s switch to the transport position, the FlexProtect side shields can quickly be folded up on both sides to reduce transport width.
