John Deere 6000 Series Tractor Starter Motor | 12V 3.0kW 11-Tooth CW | OEM RE504807

Tractors in the 6000 and 7000 families usually tell you the starter is going long before it actually fails, and the story tends to run the same way: cranking gets slower through autumn, the click arrives on its own by January, and by then a jump pack only buys a week. Ours is the 12 V gear-reduction replacement for John Deere RE504807, and Deere lists RE503226 as a substitute on the same application, so either number on a customer's order lands on the same part.

How it works

Inside it follows the Bosch PLGR arrangement you will also find catalogued as 0-001-230-002 or Lester 18361. A planetary set sits between the armature and the pinion, letting the motor spin quickly while the pinion turns more slowly with far more torque behind it, and because the battery has to supply less current across the whole cranking event, an engine that has been standing in a cold shed with thick oil still turns over.

Fitting it

Putting it on is the part of the job nobody writes in about, since the ears line up, the pinion sits at the original depth and the solenoid terminals land where the old loom expects them, which leaves the negative terminal off, three bolts out, the cables swapped over and the bolts returned to the torque figure the manual gives.

Before you order

Where people do get caught out is ordering without checking, so pull the number off the unit that is on the tractor, count the teeth if you can get a look at them, and photograph the plate when it has corroded past reading.

Dealers and repair shops can ask for quantity pricing, packing details and lead times.
