Kuhn SR 50 Series
Description
KUHN SR 50 Series SpeedRake
® wheel rakes boast exceptional quality and simplicity for smaller acreage producers who don’t require the deluxe features of the SR 100 GII. Working widths range from 15’11” to 21’4,” with a standard 8-wheel configuration and an optional extension to make a 10-wheel model. The built-in mechanical rake arm flotation slots, combined with simple leaf spring flotation, result in superior terrain following without the need for a tractor equipped with hydraulic float. The fully welded frame provides outstanding reliability and ease of use. Standard single-side raking allows flexibility for ultimate crop management.
Models
High-Clearance Design
The high-clearance frame design provides increased capacity allowing for even more crop flow and excellent windrow formation. This allows excellent ground clearance for entering and exiting fields more easily.Fully Welded Rear Frame
The rear main frame is fully welded for maximum strength and durability. This design helps the SR 50 provide reliable service and long life.Offset Rake Beam Lift
The patented rake wheel lift orientation raises the front wheels first when activating the hydraulic valve. When raking into a headland, it allows the windrow to form completely with the rear wheels raising after the front wheels to complete the windrow and not leave two short windrows at the end. Rake arms also lift faster and more smoothly for increased productivity.55” Diameter Rake Wheels
The 55” diameter rake wheels can move large volumes of crop. The right- and left-side wheels are designed to gather the crop smoothly along the wheels while forming a uniform windrow. The curved, elkhorn-style rake arms provide additional clearance for high-volume crops and reduce bunching while raking.Working Width and Windrow Width Adjustment
Seven laser cut holes provide easy and simple adjustment of the raking angle to produce the ideal windrow for the field and crop conditions. This allows for easy adjustment of the amount of crop being raked as you may see from one cutting to another or match up different mower widths.Adjustable Flotation Springs
Large, adjustable flotation leaf springs are positioned on the front of the frame for easy access. The leaf springs provide uniform flotation over field contours and reduce rake wheel wear by decreasing ground pressure. The decreased pressure also results in cleaner raking and is gentler on crop stubble. Built-in mechanical flotation slots on the end of each cylinder eliminate the need for a tractor with hydraulic float for more economical operation. The slots allow the rake arms to adapt to irregular field conditions.Expandable Rake Beam
The optional rake beam extension allows for the SR 50 8-wheel standard configuration to be easily converted to a SR 50 10-wheel configuration. This design allows for you to have flexibility when working in the field.Stable Transport
When raised for transport, the rake beams fold flat and over center to provide excellent stability. The link rods rotate the beams and provide additional support for the rake when in transport position. By having the arms positioned over the center of the machine, it provides the narrowest width possible and keeps the rake’s center of gravity between the tires.Quarter Turn Lockout Valve for Transport and Single-Side Raking
The SR 50 comes standard with two quarter turn lockout valves to help eliminate the danger of the rake being lowered during road travel. Use either or the quarter turn valve to look up one side of the rake to single-side rake on the left or right side.SPECIFICATIONS
