KUHN SR 600 GII Series SpeedRake^® wheel rakes are high-capacity, bi-fold rakes designed to meet the needs of today’s progressive hay producers. The innovative design provides unparalleled maneuverability on the road and in the field. These rakes can turn on a dime! The SR 600 GII Series rakes provide clean raking while preserving crop stubble, as well as optimized windrow formation, for a total package that offers the ultimate combination of productivity and quality performance.

Versatile, High-Capacity Design

Unique Unfolding System / Compact, Highly Maneuverable Design

The unique, innovative unfolding system moves the rear wheels forward as the rake opens, reducing the overall length of the rake by up to 7’. The shorter wheelbase improves maneuverability, allowing shorter turns on headlands, for improved efficiency and productivity. This also provides easier turning and smoother operation while raking around corners. The sliding framework also helps provide a more narrow transport position.

High-Clearance Frame

The high-clearance, raised frame design provides increased capacity, allowing for more even crop flow and better windrow formation. This design allows excellent ground clearance, with up to 21” of wheel lift to pass over previously made windrows. In transport, clearance allows for getting in and out of fields more easily without damage.

High-Capacity Rake Wheels with Windguards

55” rake wheels allow for higher raking speeds with no need to match PTO speed to ground speed. Rake wheels mounted in front of the wheel frame allow for uniform crop flow and neatly formed windrows, even raking high volumes of crop. Standard windguards improve crop flow along the wheels for a more uniform windrow. They also reduce wrapping in difficult conditions, such as tall, stemmy crops and corn stalks.

Smooth Operation on the Roughest Terrains

Independent Rake Wheel Suspension

Rake wheels, on individually floating rake wheel arms, operate at lower ground pressure than those mounted in pairs, resulting in less soil disturbance, less risk of contaminants in the windrow and ultimately provides a cleaner, higher-quality forage. Rake wheels are able to follow the ground more closely with a wide range of motion and provide consistent, uniform ground pressure for clean raking. Adjustable spring tension allows the rake wheels to adapt to different crop and field conditions.

Tandem Axles

Standard offset walking beam tandem axles improve flotation and increased stability. Tandems work well going through pivot tracks and going over borders used in flood irrigation.

Supporting Caster Wheels

Large-diameter 7.6L-15 front caster and rear wheels help maintain a uniform frame height over the length of the beam. A uniform frame height provides excellent terrain following of the raking wheels. The front caster wheels are located on the beam in such a way to minimize transport width and twisting of the frame due to the rake wheel force.

Easy Adjustments

Easy Windrow Adjustment

The windrow width can be quickly and conveniently adjusted by changing the working angle of the last two raking wheels on each side, independently from the raking width adjustment. This easy adjustment provides variable windrow widths, from 3’ to 6’, with minimal angle change, as compared to competitive models that only adjust one wheel on each side. This helps ensure gentle crop flow over the range of windrow widths.

Automatic Transport Lock

The SR 600 GII will automatically lock for transport when folding the rake from the work to transport position, without the need to get off the tractor to install manual locks.

Equipment

Raking Wheel Extension

The SR 600 GII can be converted from a 12-wheel model to a 14-wheel model, and a 14-wheel model to a 16-wheel model. These options can easily be installed in the field for maximum adaptability.

Hitch Extension

In order to convert SR 600 GII from a 14-wheel model to a 16-wheel model, a hitch extension must be installed, along with the Raking Wheel Extension kit. The hitch extension can also be used on 14-wheel models if you need to accommodate tractors with longer wheel bases.

Intermediate Caster Wheel

The bolt-on option provides additional support and more positive raking when crossing difficult terrain like holes, ditches, ruts or irrigation pivot tracks. This option is standard on SR 614 and 616 models. It is optional on the SR 612 model.

Adjustable Clevis or Ball Hitch

A clevis hitch comes standard with all models. A ball hitch is optional.
