This 546-page New Holland LS140, LS150 Service Manual has one job: putting factory answers in your hands for both skid steer models, no guessing required. Open it up and you're into full wiring diagrams for the entire electrical system, hydraulic schematics covering the control valve, pump, and cylinder circuits, and a troubleshooting section that walks you through the boom and axle systems fault by fault. You also get exploded views for nearly every component group, so parts orientation stops being a mystery. Set your pipe thread fittings to 41 N-m (30 ft. lbs.) and confirm the crankcase holds 5.7L with a filter change, numbers straight from the factory page, not a forum thread. Your hydraulics locked up? Reset the EIC security code and move on. Bookmarked by system, searchable by keyword: pull it up on a tablet in the shop and get back under the machine.
