Canadian Spraying Experts Bring Workshops to NZ Growers
Two Canadian spraying experts, Tom Wolf and Jason Deveau, are visiting New Zealand in early August to ensure that arable growers are hitting the target with this key piece of equipment.
Based around a full-sized, well-known Robinson R44 helicopter, the autonomous machine has a capacity of 500 litres.
While we are seeing more and more drones being used in New Zealand agriculture, we’re some way behind the US, where in places like the Midwest, the drones are certainly bigger than Texas.
Equipped with 33ft (10m) booms and a 110gal (500l) capacity tank, the new Sprayhawk drone is being classed as the biggest agri-spray drone on the market.
Designed and developed by Rotor Technologies, based in New Hampshire, USA, the new unmanned aerial vehicle (UAV), The Sprayhawk, has been released to market with a hefty price tag of $1.47 million.
Based around a full-sized, well-known Robinson R44 helicopter, and fully controlled by a two-man ground crew, the autonomous machine has a capacity of 500 litres matched to 10 metre booms and a capability of covering up to 100ha/hour, with a maximum take-off weight of 1133kg.
Powered by a Lycoming six-cylinder aviation engine that can help deliver a working speed of over 125km/h and a flight time of 50 minutes between refuelling, the Sprayhawk can take off and land vertically, then use autonomous spray path and terrain following algorithms, as well as camera and LIDAR sensor technology for detecting wires and avoiding obstacles.
Impressively, the Sprayhawk matches the spray speed and capacity of manned aircraft, while offering significantly lower operating costs and improved safety.
The first Sprayhawk production aircraft is currently undergoing ground testing ahead of delivery to an agricultural partner in the US Midwest later this year. The first batch of production Sprayhawks will be delivered to early-access partners throughout spring 2025 and are expected to begin commercial spraying operations in the 2025 corn season.
For 2025, the first production run will be limited to 15 aircraft, with customers receiving a “ready-to-spray” pack which includes the Sprayhawk UAV, a 110-gallon tank and 33-foot spray boom system, a helicopter transport trailer, and a ground control station. Rotor offers training, maintenance plans and regulatory support to customers to ensure seamless deployment in any agricultural setting.
A company source commented, “Many of the agricultural drones on the market today are unlikely to stand the test of time. The need for larger and more reliable aircraft is clear and our aggressive introductory pricing for the 2025 model year is designed to speed up adoption.”
Associate Agriculture Minister Mark Patterson says his party – NZ First - isn’t opposed to the “trade element” of a free trade deal with India.
The managing director of a company seeking to build a solar farm in Canterbury says receiving fast-track approval is a “really positive outcome”.
Retiring MP and dairy farmer Mark Cameron is blasting the Green Party for proposing to ban the use of synthetic fertiliser and cutting cow numbers.
A huge reduction in ACC claims from on-farm accidents over the last five years is due to thousands of small, practical decisions being made in sheds, yards, paddocks and around kitchen tables across the country, says Safer Farms ambassador Lindy Nelson.
Wayne and Ange Moxham of Horowhenua have just been named as Fonterra's top organic performer for milksolids. As well as providing organic milk to Fonterra, the couple also sell Udderly Organic milk to more than 100 outlets in the region and are embarking on another exciting venture producing organic gelato. Reporter Peter Burke went along to see their farming operation.
Certainty and a clear understanding of the needs of rural communities is a critical outcome in the series of government reforms that are taking place at present.
