Built for Real Farm Work
This alternator is engineered for the demanding conditions these German tractors face every day. From early morning starts in freezing weather to long summer days running hay equipment, it delivers dependable charging power. The wide range of compatible models means this one alternator covers everything from compact utility work to serious field operations.
Made to Last
MAHLE doesn’t just rebadge generic alternators – they build them specifically for agricultural use. This unit resists moisture, dust, and the constant vibration that comes with real farm work. The robust construction means it’ll keep charging reliably season after season, matching the durability your tractor was built with.
Good to Know
Installation is straightforward using your existing belt and wiring connections. Before installing, check your drive belt condition and make sure connections are clean and tight. If your old alternator failed, verify your battery is still in good condition – a weak battery can overwork a new alternator. After installation, check that you’re seeing 13.8 to 14.4 volts at moderate RPM.
