O-rings and lip joints ensure sealing for a longer service life. 2 No gearwheel overhang: Convex treated and forged steel gearwheels so that the drive forces (a) are transmitted at the centre of the upper roller bearing (over-dimensioned) without creating an overhang. High capacity shaft guidance and torque transmission capability thanks to the important spline length in contact with the shaft (b). 3 No maintenance on bearings: Large dimension conical roller bearings are always perfectly aligned in a one piece cast housing not subject to distortion. Factory preloaded with a calibrated spacer (c), no further adjustments are required. 4 Perfect bearing hold, gear case protection: the thick cast iron housings (35 mm /1.38 ” on HR 1004, 25 mm on HR 104) ensure perfect bearing hold and trough protection against wear and distortion. 5 Reinforced sealing: cassette seal providing very efficient protection against bearing pollution. 6 No play on the spline level: rotor shafts with rolled splines obtained by metal compression (no milling). Perfect connection with the shaft thanks to the conical centring of the blade holders (KUHN patent), preventing play on the spline level. 7 Oval shaped blade holder: to prevent stones from getting jammed and to facilitate their evacuation as well as the evacuation of plant residues. 8 Blades highly resistant to shocks and wear thanks to their thick section: Heat treated 16 mm thick and 310 mm long FAST-FIT® blades. Also available in DURAKUHN® coated version or “forward action ” version OPTIMIX® or 360 mm long blades. www.kuhn.com They do not by-pass difficulties: soil inevitably passes through the blades The features of the KUHN power harrow casing – The casing, housing and tine holders form a compact and very robust unit reducing twisting forces on the housing. – The small distance between casing and tine holders prevents stones from getting jammed and the soil flow is directed towards the blade working area. Choose blades according to the soil. and applications 3 major goals so that cultivations get off to a good start: – Clods on top, fine soil around the seed, – In depth packing, – Exact levelling, to ensure even germination Exclusive features: Advantages of the KUHN power harrow blade: – Bevelled, twisted specific shape.
