Agricultural
Starter motor commutators for tractors and agricultural machinery
Tractors, combines and sprayers sit for months and then work round the clock. Moisture and long storage pit the commutator surface; harvest season then burns it. A new commutator fitted to the existing armature gets the machine back out quickly and avoids the cost of a complete starter for an older model that may be hard to source.
What we see with agricultural starters
- Tractors, combines, sprayers, balers, irrigation pumps and grain dryers
- Common starter brands: Bosch, Lucas, Iskra, Magneton, Denso
- Older Lucas and Bosch units often use sizes that are no longer stocked by the OEM; made to measure covers these
Not sure which one you need?
Send a photo of the commutator and the number stamped on the armature. We match it against the drawings we hold and send a firm price within 2 working days. If it isn't a standard size, we make it to measure.
All standard sizes
Filter to the sizes for this application once they are confirmed; until then the full range is shown.
