Transforming Unproductive Land: The ELHO Scorpio 550 in Action

Clearing stones from paddocks is a tough but necessary task, one that needs to fit in between other jobs around the farm. For contractors and farmers alike, efficiency is key, and finding a machine that can reliably handle the job makes all the difference. The ELHO Scorpio 550 stone picker has become a valuable addition to farms and contracting businesses, proving its worth in challenging conditions.

With a fully hydraulic drive system, the Scorpio 550 operates smoothly and efficiently. It requires a hydraulic flow of 85 litres per minute, with an optimal working pressure between 110 and 150 bar. The machine is designed to run on a tractor’s standard dual-function hydraulic coupling, making it a straightforward attachment without requiring additional modifications. Its maximum continuous power use is 24 kW, and the tractor’s own cooling system ensures oil temperatures remain at an optimal level, preventing overheating during extended operation.

One of the standout features is its automatic depth adjustment, allowing the machine to follow the ground’s contours while maintaining consistent working pressure. This not only ensures an even collection of stones but also makes operation easier, even in dusty conditions. When needed, the hydraulic system increases pressure to a second pickup motor, ensuring no loss of efficiency when dealing with heavier loads. The lifting force at the end of the tines reaches 700 kg, providing the power needed to clear even the most stubborn stones.

The Scorpio 550’s tines are made from Hardox 500 steel, which is more durable than traditional steel spring tines. This allows them to rotate at higher speeds, improving the sieving process and breaking down organic material more effectively. The pickup drum has a diameter of 1.8 metres and rotates at 80 revolutions per minute, while the tines themselves spin at 125 revolutions per minute. The design incorporates rubber bushings, allowing the sieve bars to flex laterally, preventing blockages and ensuring a smooth operation. If needed, the tines can flex up to 500 mm, lifting out of the sieve to avoid obstructions.

With a working width of 5.5 metres, the Scorpio 550 is capable of handling significant areas efficiently. It can pick up stones ranging from 25 mm to 400 mm in size, ensuring a comprehensive clearing process. Its large hopper, with a capacity of up to two cubic metres, allows for extended work periods without constant emptying. The machine’s tipping height of 2.7 metres makes unloading straightforward, whether into a trailer or directly onto the ground for further handling.

For contractors like Ben Scott of Hakatere Valley, the Scorpio 550 has become an essential part of the business. Having added the machine to his fleet in 2024, he quickly saw its potential. With the abundance of rocks in the area, many paddocks that were previously left untouched are now viable for cultivation. “It’s proven its place where a lot of guys that probably wouldn’t bother with some paddocks, it’s an option – we can clear it, it’s feasible,” he says. “It’s worthwhile getting into and is a big part of my business now.”

One of the features Scott appreciates most is the machine’s width, allowing him to cover large areas efficiently. Since adding the Scorpio 550 to his operation, he estimates he has moved between 3,500 and 4,500 tonnes of stone. The volume varies depending on the job, but in one instance alone, he cleared between 2,000 and 2,500 tonnes. With an average capacity of 30 to 35 tonnes per hour, the machine has significantly boosted productivity, turning previously unworkable ground into productive farmland.

Designed for durability and ease of maintenance, the Scorpio 550 features bolted hopper components that can be easily replaced if necessary. The entire support structure follows the same principle, ensuring longevity and reducing downtime. Large 560/60 R22.5 bogie wheels provide stability across uneven terrain, while the rake wheels are designed to turn with the machine, improving manoeuvrability.

The addition of optional extras like a hydraulic unit, a screen for smaller stones, and a K80 towing eye further enhance the machine’s versatility. With its combination of power, precision, and efficiency, the ELHO Scorpio 550 is more than just a stone picker – it’s a solution for making unproductive land usable, helping farmers and contractors get the best from their land.
