Also available on the standard 1.2m head machine to improve reach, particularly into the more difficult-to-access areas, is a Shift Rail System (SRS) mechanical head sliding mechanism that provides +/-40cm movement on the flail head.
Kuhn’s Poly-Longer long-reach hedge cutter was launched in 2010 and sits in between the company’s smaller Agri-Longer and larger Pro-Longer models as a mass-market machine.
Poly-Longer hedge cutters are available with a choice of single–lever on/off electronic controls or electronic proportional control from a joystick, with the latter providing the ultimate in operator-friendly operation. Overall, the Poly-Longer is robust and simple to operate with a compact designed head operating with a 57hp motor. The head is fitted as standard with T–flails that operate at 2,900rpm rotor speed.
Hydraulic drive motors are fitted with oil coolers as standard allowing the machine to maintain full operating power in the most demanding working conditions and with the additional benefit of a reduced oil capacity that ultimately cuts running costs. There are separate and fully independent pumps serving the rotor and arm movements.

Parallelogram arm construction means that a single control operates the main and outer booms simultaneously, and improves the clearance as the ram is located within the structure. All hinges are flanged and protected for minimal play and good hose holding. All machine joints, including the hydraulic rams, are enclosed and greased for life for minimum wear and maximum durability.
The Poly-Longer has a hydraulic safety break–back system with 120-degreepower slew angle. Hoses are protected through either metal casing or braided sleeves, and a new pivoting plate feature reduces wear at a key point.
The Poly-Longer is designed with its hitching system close to the frame of the machine, which shortens the overhang and aids stability and operator visibility. The PTO shaft is centred, which reduces noise and extends component life. Road lights are included as standard on all models.
Models of the Poly-Longer available in the UK will have a starting price of £21,491 (correct at December 2012). The 1.5m head option is available for an additional £1,910, while the SRS option adds £298 to the standard model price.
