Heavy-Duty Tongue & Delta Frame
The SR 300 Series wheel rakes feature outstanding strength and durability to provide the machine with a long life. The angled design of the tongue, as it comes down to the hitch, allows for clearance for tractor draft arms while turning. The hydraulic hoses are routed through the tongue which provides protection from damage and a clean look.
Heavy-Duty Cantilever Rake Beams
Heavy-duty, square-tube rake beams provide a solid structure and outstanding durability, even when raking the widest windrows. The cantilever design provides a solid support for the rake wheels and allows them to closely follow the ground. Rake closer to fences, irrigation borders and other obstacles, without the need for caster wheels.
Specially Curved Rake Wheel Arms
Specially curved rake wheel arms provide high capacity for uniform crop flow and neatly formed windrows. The design offers outstanding clearance when crossing over windrows or moving between fields as the rake wheels can be lifted up to 21”.
Hydraulic Parallel Folding
The hydraulic parallel folding allows the rake to be set conveniently from the tractor seat. The rake beams telescope in and out, in unison, allowing on-the-go raking width adjustment. This provides the operator the flexibility to set the working width based on the mower width and windrow width. Guide surfaces on the telescoping rake beams are high-density polyethylene (HDPE) lined, and provide smooth and reliable performance and outstanding durability. They are removable, replaceable, have simple maintenance and long life.
Alternate Raking Positions
The standard “V” raking mode gathers the maximum crop width. Standard right-side only and left-side only raking allows the customer to reach tight corners and turn over wet crop for faster drying. To switch raking positions, simply turn either quarter turn valve on either side to lock the rake wheels in the raised positioned.
Rapidly Adapt to Your Field Conditions
You can quickly and conveniently adjust the width by changing the working angle of the last two raking wheels on each side and independent of the raking width. This setting remains constant as the working width is altered providing on-the-go adjustability while preserving the windrow width.
Independent Rake Wheel Suspension
Individually floating rake wheels are mounted on spring-suspended arms and can be adjusted independently from front to back. This reduces soil disturbance providing cleaner raking and resulting in higher-quality hay.
Rake Wheel Lockout
The front two and back two rake wheels can be locked out to adapt to specific situation (the back three rake wheels on the SR 314). Handle heavier crop conditions more effectively by locking up the front wheels. Produce a wider windrow or turn two windrows at once without combining them by locking the rear wheels.
Hydraulic Rake Wheel Operation
The hydraulic rake wheel operation increases spring pressure on all rake wheels simultaneously and raises the rake wheels together. Two double-acting cylinders provide active lowering of the rake wheels, eliminating the need for a tractor with a hydraulic float circuit.
Transport Wheels
Transport wheels are forward and centrally positioned to allow for a small turning radius, easy maneuverability on headlands and in small or oddly shaped fields.
