Don’t let Aussie crop conditions dictate your yields.
Maximise your crop potential by adding high velocity air to your header with a Crary Wind System™ (CWS). The CWS will fit on most auger and draper heads and is easy to install.
Request a QuoteHow it works
The CWS works by using the existing tyne reel and adding a manifold in front of the reel to produce a curtin of high velocity air over the cutter bar, feeding more crop over the knife, more crop in the grain bin & more money into farmers’ pockets.

Gear Box Benefits
- A Parallel shaft design reduces wear points and imposes field serviceability making it easy to maintain
- 45% less moving parts versus the competition that are sealed and out of the elements
- Compact design packs a punch allowing us to provide enough air for a 40 foot plus headers from a single fan when combined with a Dual Flow system.
- Gear drive eliminates losses due to belt slippage
Additional Features
- Flex hose allows fore and aft adjustments on-the-go
- 12 Volt Electric Actuator allows for precise positioning of air curtain with in-cab controls
- Direct Drive Gearbox™ efficiency drives the fan rotor
- Optional Brush Kits reduce material buildup
- Crary 8” custom fan generates high velocity air flow
outlasts other rotors by at least 3 times as long in both lab and field tests. Patent-pending carbide clad inside lower blade edges is designed to increase longevity.

Why Buy
a Crary Wind System™?
Dual Flow™ Technology
Provides airflow in two directions creating an even curtain of air across the entire cutter bar. The Crary manufactured fan coupled with Dual Flow system can produce wind speeds in excess of 300 kph at the cutter bar on head sizes up to 45 feet.
Long Lasting
The Crary® high pressure fan utilizes a Crary® Infinity Steel Rotor™. Natural dust and dirt particles can be coarse and abrasive. The patent-pending carbide-clad lower blade edges are designed to increase the longevity of your air system.
Less Volunteer Crop Germination
Additional yields also means less volunteer crop germination during the followings seasons preparations for seeding and reduces costs via less summer spraying.
Gearbox Driven
Air is supplied by an 8” blower shaft and driven by a Series II Gearbox™. This gives the CWS more air than competing wind systems that rely on belt driven fan rotors. A gear-driven system requires less horsepower, gives you more air, and a consistent air stream that doesn’t slip like belts do under load.
Increase Yield
West Australian farmers estimate that the CWS yielded an additional 60kgs per hectare when harvesting Lupins.
Reduce Shatter Loss
Proven particularly effective for shatter-prone crops such as lupins and barley.
Faster Ground Speeds
Farmers report they no longer wait for bunched crop to clear the platform. Faster ground speeds increase profits and reduce fuel expenses.
After Sales Support
Crary® systems carry a warranty guaranteed to protect against manufacturing defects and Harvestaire carries a range of spare parts to minimize any downtime
