When you're running long days in the field and your alternator starts acting up—dim lights, slow cranking, or that warning light that won't quit—you need a reliable replacement that'll keep your operation running without breaking the bank. This MAHLE-manufactured 70-amp alternator delivers the dependable charging power your tractor needs, whether you're pulling a disc through tough soil or powering hydraulics on a loader all day long. What You're Getting Solid 70-amp output that handles modern electrical demands without overworking the charging system 14-volt design maintains proper battery charge and keeps all your electrical systems running strong MAHLE quality construction engineered specifically for agricultural applications Direct replacement that fits multiple brands—saves you time hunting for brand-specific parts Built for Real Farm Work This alternator works across a wide range of tractors from utility models up to larger row-crop machines. Whether your Massey Ferguson is running a bush hog, your Ford New Holland is pulling implements, or your Case IH is doing loader work, this unit keeps the electrical system healthy through whatever work you throw at it. Made to Last MAHLE doesn't just rebadge generic alternators—they engineer them for the tough conditions farm equipment faces. The sealed housing keeps dust and moisture out, while quality bearings handle V-belt tension without premature wear. The internal voltage regulator maintains steady output whether you're idling while hooking up implements or running at PTO speeds. Installation Notes Before installing your new alternator, check why the old one failed—worn belts, corroded connections, or a bad battery can kill alternators prematurely. Clean the mounting area and verify proper belt alignment to prevent future problems. After installation, test the system with a voltmeter; you should see 13.8-14.4 volts at moderate RPM.
