BUILDING A MOWER 1 2 The

BUILDING A MOWER 1 2 The process starts with steel sheets with all the holes profiled out, which are bent into shape by a hydraulic press to form the box shape of the bed. The sections are then joined together by robot welders. The continuous seam eliminates the need for bolts or gaskets, providing strength and flexibility. It also ensures that the seal remains tight, which allows permanent lubrication. “It negates the need for oil changes,” James Duggleby explains. “As long as the bed is not damaged oil levels only have to be checked and topped up.” The industry leader in hay and forage equipment The heat of the welding can cause slight distortion so the bed is precision-mounted on a milling bed where a computer-controlled milling machine ensures all holes are in the right place and every surface is flat and true. “Both the internal and exterior surfaces are milled,” James Duggleby comments, “it is only to the finest of tolerances, but the devil is in the detail. The operation ensures the gears and bearings are mounted in the correct position and alignment, so they are running straight, giving a more efficient drive and avoiding losses. It can be an overlooked process but it is a key element in everything fitting together, making sure we deliver the quality product the farmer expects.” 3 8

4 Once the disc hub mounting bolts have been precision-welded to the bed in a pattern that ensures the SafeCut disc hub locates in the exact place so the gears mesh in the optimum position, the bed is paint dipped in, Krone says, one of the most advanced plants in Europe. Both internal and exterior surfaces are coated in an 8-hour process, which includes electrostatic application of the first of two coats. 5 6 The painted bed then moves to the assembly line where the large and small gears, which are made in-house, are inserted and the SafeCut satellite hubs are located. 7 An important stage is spinning up the bed at a reduced speed and swilling out the inside with oil to clear out swarf and debris. This is a key element to ensure the lifetime lubrication. The bed is then pressure tested to 800 millibars to ensure it is fully sealed and there are no oil losses. 8 The final test before the seal of approval. As part of the quality control procedure once the skids have been put on and the discs assembled the bed is run up to full speed for seven minutes.
