Kubota Tractor Starter Motor | OEM 15852-63010

Kubota's small diesel starters are unglamorous objects, and this one sits at the small end of even that scale — 0.8 kW, twelve volts, a nine-tooth pinion turning clockwise off a Mitsubishi direct-drive nose with no reduction gear in between. What makes it worth stocking is the breadth of the applications rather than the output. It left the works on lawn and garden tractors such as the G2000 and G6200, where the engine bay is tight and the duty cycle is short, and on the compact utility B1550 and B8200, where the same motor has to spin a three-cylinder diesel that has been standing in a cold shed since October. One part number, two rather different working lives.

Fitment and Purchase Checks

Fitment lists for this number read like a roll call of small Kubota work — G3200 from 1983, the G4200 and G5200 the year after, G6200 in 1986, G2000 in 1989, then the B8200 and B1550 through the late eighties, with the G2460 running on to 2007 — and that spread is exactly why a photograph beats a table. Count the teeth on the old pinion before anything is ordered, since most references print nine and a few still print eight, then check the drive end against the picture rather than the model year. The answer comes back quickly enough: what the unit costs, how it ships, and what happens if the plate turns out to describe something else.
