When you're counting on your John Deere to start every time—whether it's 20 below or your engine's got serious hours on it—this 4.0 kilowatt starter delivers the muscle you need. Big tractors need serious cranking power, and this heavy-duty unit fires up everything from 6200 series utility tractors to the massive 9120 row-crop machines that power the biggest operations. What You're Getting Powerful 4.0 kilowatt motor that spins high-compression diesels with authority 11-tooth drive gear precision-matched to John Deere flywheel specifications Heavy-duty solenoid ensures solid engagement even in brutal conditions Sealed housing keeps out moisture and field dust that kill lesser starters 12-volt system works with your existing electrical setup Built for Real Farm Work This starter powers the workhorses that handle the biggest jobs—pulling 16-row planters, running thousand-gallon sprayers, or moving grain carts during harvest crunch time. These machines work long days in tough conditions, from sub-zero morning starts to hot restarts after running hard all day. When you've got a tight planting window or need to finish harvest before weather hits, your starter has to work every time. Made to Last The 4.0KW motor develops enough torque to handle large displacement diesels with high compression ratios, while oversized brushes and heavy windings take the punishment of sustained cranking. The 11-tooth pinion gear is precision machined to mesh perfectly with John Deere ring gears—no grinding or premature wear from mismatched components. Installation Notes This high-output starter demands good electrical connections and strong batteries. Clean all mounting surfaces and electrical connections thoroughly before installation—even slight corrosion causes voltage drop and slow cranking. If you're replacing due to failure, check your ring gear for damaged teeth that could destroy your new starter.
