From the Vary-Touch hydraulics and three-point linkage through the PTO, belt pulley, brakes and electrical system, this International Harvester B-275 operator manual PDF covers the whole tractor in 106 pages under OEM ID 1026273R6. Diesel and petrol wiring diagrams trace each circuit from the battery, generator and starting motor out to the glowplugs or the petrol ignition system, so a no-start becomes a continuity check. Operation fills the largest share of the book, with remote cylinders, auxiliary control valves, check chains, wheel weights and tread adjustment, while the lubrication chart, routine servicing schedule and fault tracing pages show you what to grease, when to do it, and why the engine won't idle. Set fan belt tension to 3/8 to 1/2 inch and generator belt tension to 1/4 inch. A parked tractor burns daylight you can't get back. The PDF is bookmarked and has a searchable text layer, so it goes with you to the shed, the headland or wherever your B-275 stopped.
