ELHO Stone Picker
Maximising land usage efficiency while sustaining soil quality without compromise.
The ELHO in action
ELHO Scorpio stone picker at CIA Ltd
Unlocking stony ground
Thousands of years ago, the tremendous power of ice age glaciers carved through the Southern Alps and released rocks and sediment from the Arthur’s Pass headwaters, forming alluvial deposits from the mountains to the sea – a common occurrence on many New Zealand farms.
Farms have been carved out of this rich soil, however some land has yet to reach its full potential due to stones and rocks scattered on the surface. Stones constitute a significant cost burden each year due to their potential to disrupt harvesting machines – with downtime from stone damage ranging from one week to more.
To address this long-standing difficulty, CIA Ltd added the ELHO Scorpio 550 to its range. This powerful machine efficiently collects stones without damaging the soil.
Lifting and unloading rocks
Built for Canterbury
Engineered to remove stones
Fully hydraulic drive
85 litres/minute hydraulic flow at 110–150 bar, using a tractor’s normal dual-function coupling.
Automatic depth
Follows the ground surface with constant working pressure – even in extremely dusty conditions.
Hardox 500 tines
Rotate faster than steel spring tines for better sieving, soil removal and breaking up organic material.
No blockages
Rubber-bushed tines flex up to 500 mm and lift out of the sieve to prevent blockages.
Specifications
The hydraulic drive is designed for a nominal pump size of 110 l/min. The maximum continuous use is 24 kW, and the tractor’s own cooler keeps the oil temperature optimal.
The hydraulic system can temporarily increase pressure to the second pickup motor when needed, and the lifting force at the end of the tines is 700 kg. The diameter of the picker is 1.8 metres and rotates at 80 r/min, while the tines rotate at 125 r/min.
