Stonepicking

Our ancestors have fought with stones for centuries, and to this day we are still fighting! Stones in the field can incur huge costs each year by causing damage to harvesting machines. Costs are generated not only by the necessary repairs, but also in terms of lost working hours. Harvesting can be delayed by up to a week or more, depending on the extent of the damage to the harvester or mower. To provide a solution to this age-old problem, ELHO designed the Scorpio 550 fully hydraulic driven stone collector!

The ELHO Scorpio 550 collects stones efficiently!

Picking stones is tough work. Whether you are a farmer of contractor, stone picking has to be timed in between other tasks – usually before ploughing or after harvesting.

The ELHO Scorpio 550 stone picker is equipped with unique solutions that make it easy to remove stones from fields.

One of the key features of the Scorpio 550 is fully hydraulic drive. The hydraulic flow is 85 litres/minute, which is achieved with 110-150 bar. The hydraulic drive is designed for use with a tractor’s normal dual-function hydraulic coupling and 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.

Automatic depth adjustment enables the machine to follow the surface of the ground with a constant working pressure. This makes it easy and pleasant to operate the machine, even in extremely dusty conditions.

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.

Sturdy Hardox 500 tines can rotate at higher speeds than traditional steel spring tines. The higher rotation speed improves sieving and soil removal, and it also breaks up organic materials better. The diameter of the picker is 1.8 metres and rotates at 80 r/min, while the tines rotate at 125 r/min.

The Hardox 500 tines have rubber bushings, allowing the sieve steel bars to flex laterally. All of the tines flex backwards and lift out of the sieve to prevent blockages. The maximum tine flex is 500 mm.

The ELHO Scorpio 550 SF loads stones directly into the trailer!

The ELHO Scorpio 550 SF (SideFlow) stone picker features a conveyor system that transports the material out of the machine, enables stones to be loaded directly into a trailer.

The centre conveyor has a very sturdy structure and lifts stones from the ground. The kinetic energy of the stones is dissipated before arriving at the side conveyor, which has a lighter structure and is equipped with spring steel rods and a rubber mat. Both conveyors effectively sieve dirt off the stones.

The conveyors can be stopped temporarily, for example in the headland, to avoid an obstacle or when switching trailers. The rake tines continue to collect stones all the time, which are then lifted onto the conveyor when it is reactivated.

The Scorpio 550 SF stone picker is controlled electronically, as on the Scorpio 710 model. The Scorpio 550 SF is ideal for large field areas where it would be inefficient for the pulling tractor to unload the hopper by itself.

Scorpio 710

Drawbar

Min 110 l/min

Min 90 kW

The ELHO Scorpio 710 is an extremely efficient 7-metre stone picker!

The popular ELHO Scorpio 550 stone picker now has a big brother! The Scorpio 710 has a working width almost two metres wider than the smaller model. The wider pickup rotors significantly increase productivity.

The Scorpio 710 features an electronically controlled valve block that can be used with a tractor that has LS hydraulics or with an optional hydraulic unit. Load-sensing hydraulics make tipping the hopper even faster.

The large stone picker is simple to operate from the cab of the tractor using the control unit with colour display. The control unit enables precise adjustments to the working depth, for example.

The screen size can be adjusted hydraulically during operation by varying the distance between the sieve bars.

The new pickup rotors are even more effective at sieving soil. The spiral pattern on the inner tines removes the soil to the side while still lifting stones to the centre. The outer metre of the pickup rotors feature a traditional spiral pattern to ensure that stones at the edges are collected to the middle of the machine.
