A small upgrade with an outsized effect in light wind: the head pivot bearing lets the windmill head swing to face the breeze with less resistance, so the mill tracks and starts sooner on calm days...

Puts a modern OWS aerator head on an old farm windmill tower — even one that's stood for 50–100 years. The steel receiver bolts or welds to the legacy tower, then accepts the current OWS windmill...

Brass two-way selector for balancing airflow between two diffusers or zones on a windmill or electric aeration system. Metering the split keeps both diffusers working evenly — no starved zone, no...

Heavy-duty screw-in ground anchors purpose-made for wood-tower windmills installed on dirt or grass. Anchoring stops tilt and shift in storms and soft ground — protecting not just the tower but the...

Two replacement tail arms with hardware for OWS large windmill aerator and yard-decor windmill heads. Not for garden-size windmills.

28" galvanized blade with the angled offset tip that builds the full 73" OWS head — the longest in the industry. The extra blade length adds torque, which is what lets these mills turn in 3–5 mph...

24" square-cut universal replacement blade in galvanized steel. Fits all OWS windmills; corrosion- and warp-resistant so the head stays balanced. Use it to restore a damaged head or replace a thrown...

18-gauge galvanized brace that keeps windmill blades aligned and rotation balanced. A missing brace is the usual culprit behind blade wobble; this universal part drops into any OWS head.

Weather-resistant galvanized replacement dome for OWS windmills. Installs quickly with the included self-tapping screws and keeps the hub protected from rain and debris.

OEM-spec galvanized ground stake clamps for OWS windmill towers, sold as a complete set of three pairs. Corroded or loosened clamps let a tower work itself unstable; a full replacement set restores...
