When your big John Deere won't turn over on a cold morning or starts getting sluggish after years of hard work, you need a starter that can handle the job. This MAHLE 4.2KW heavy duty starter delivers serious cranking power for those large displacement engines that don't take kindly to weak starters—especially when you've got cattle waiting for feed or crops that need harvesting. What You're Getting Powerful 4.2 kilowatt motor that spins large diesels with authority, even in cold weather Three-bolt mounting design that stays put under heavy vibration and engine torque Ten-tooth pinion gear that meshes perfectly with your flywheel for smooth engagement MAHLE quality construction that handles the high current draw without overheating Left-hand mount with clockwise rotation—exactly what these tractors need Built for Real Farm Work This starter powers up the 6000 series workhorses that handle your biggest jobs—whether that's pulling wide tillage equipment, running large balers, or powering through long harvest days. These aren't light-duty tractors, and they need a starter built to match their capabilities. Made to Last MAHLE builds this starter to handle the punishment of daily farm use. The 4.2KW rating isn't just peak power—it's sustained cranking ability for those stubborn starts when engines are cold or have high hours. Quality internal components resist the wear that comes from repeated high-amperage starting cycles. Installation Notes This is a direct replacement with the same three-bolt pattern and mounting configuration as your original. Check your battery cables and connections while you're in there—a 4.2KW starter draws serious current, and corroded or undersized cables will cause problems down the road. Make sure all three mounting bolts are properly torqued to prevent loosening.
