Before the first cut you will be hitching up, setting the drive shaft length and tensioning belts, and this 92-page Claas Disco 2650 operator manual PDF (OEM ID 293 857.5) covers that work across eight variants of the Disco 3450, 3050 and 2650 disc mower family. Operation and maintenance fill most of the book, from cutting height, collision protection and swath discs to changing knives, replacing mower discs, conditioner tines and a malfunctions section, finished with a lubrication chart. Technical data shows you how to work out axle loads and minimum ballasting for your tractor. Fill the 2650 mower head with 4.0 litres of oil (5.0 on the 3450), and set suspension springs to 50 mm of free thread on the 3050 and 2650. Just you, the mower, and nobody to ask. Bookmarked and text-searchable, the PDF goes wherever the mower is parked, so this season's cut stays on schedule.
