A mower's wheel hub takes a beating most people never think about — rocks, curbs, tree roots, the constant jolt of turf that isn't perfectly flat. Cast iron handles that abuse better than stamped steel or aluminum alternatives, which is why it's still the material of choice for hubs on commercial-grade mowers and heavier residential units.
Sourcing hub castings for a mower line usually means dealing with a handful of recurring headaches: bore tolerances that don't quite match the axle, spoke patterns that need reworking for a new wheel design, or lead times that don't fit a production schedule. We cast to the bore diameter and mounting pattern specified in your drawings rather than pushing a fixed catalog size, and our machining line finishes each casting to the tolerance the axle assembly actually needs.
For teams building or updating a mower model, that usually means fewer fitment surprises during assembly testing. For distributors stocking replacement parts, it means hubs that match OEM specs closely enough to sell as direct-fit replacements rather than "close enough" substitutes.
Production runs from small development batches through full-volume orders, with the same material and dimensional checks applied regardless of order size. If you're specifying a hub for a new mower design or replacing an existing pattern, send over the drawing or a sample part and we'll quote against that directly.
