Servicing the John Deere 4X2 and 4X6 Gator requires specific data for three distinct engine families: air-cooled gas, liquid-cooled gas, and diesel. This 692-page technical manual (OEM #TM1518) covers them all. You will find electrical schematics detailing full harness routing for both configurations, alongside hydraulic system diagrams and repair procedures for the powertrain, brakes, steering, and attachments. The troubleshooting sections deliver diagnostic charts, clearance tables, and test values directly from the factory. Need to torque the wheel mounting cap screws to 88 N•m (65 lb-ft) or set the FE290D carburetor slow idle mixture screw to 1-3/8 turns? The exact numbers are included. Because the PDF is bookmarked and searchable, you can jump straight to the required system without flipping through hundreds of pages.
