Kuhn Farm Machinery has updated its entry-level range of disc mowers with the arrival of four new versions of its basic GMD model. Available in working widths from 1.6 to 2.8 metres, the four model range uses Kuhn’s 100 Series cutter bar and Protectadrive system to deliver high quality and reliable grass cutting.
The GMD range is designed for small or medium-sized farms where a simple and reliable machine is required. The GMD 16, 20, 24 and 28 machines feature working widths of 1.60m, 2.00m, 2.40m and 2.80m respectively and are now fitted with Kuhn’s 100 Series cutter bar which features the company’s Protectadrive safety system.
“The Series 100 cutter bar is a standard feature on Kuhn’s higher specification mowers, and is now available on the GMD range,” explains Duncan McLeish, UK Sales Manager for Kuhn Farm Machinery. “It gives an exceptionally clean cut which not only preserves the nutritional value of the cut grass, but also promotes faster sward re-growth.”
The Series 100 cutter bar is equipped with large diameter gearwheels with reinforced teeth for improved wear and impact resistance and uses disc pinion shaft bearings which are symmetrical in relation to the radial forces endured by the disc. These bearings are fitted in an anti-distortion housing to enable them to withstand the heaviest loads and to optimize the load balance incurred by each disc.
“The cutter bar is specifically designed to have a long service life and to be easily serviced,” Mr McLeish adds. “It is protected by Kuhn’s anti-impact Protectadrive system which protects the gear train should an obstacle be struck. Each disc shaft features a shear groove which is designed to fail should the mowing bar come into contact with a foreign object. By making the sheared shaft easy to replace, any downtime is kept to a minimum, and in fact, the mower should be operational again in less than 15 minutes.”
For increased machine protection, the new GMD range also uses a swath wheel to prevent the cutter bar from coming into contact with the ground, while a safety break-back system allows the mower to shift rearwards should an obstacle be struck.
