Muck and slurry 2015: Spreading on a large scale

Insights

Self-propelled muck and slurry spreaders are increasingly in demand for their light tread and massive capacity, and despite Agco’s withdrawal of the Terragator from the European market, there’s still plenty of choice. Jane Carley reports.

The Holmer Exxact Terra Variant system vehicle, distributed by Agrifac in the UK, can be fitted with slurry tanker and injection and solid manure application equipment.

 

It is powered by a Mercedes Benz, 598hp engine and drives via a Funk DF 500 powershift transmission, with 18 forward and 6 reverse gears. Front-axle suspension with gradient support and automatic levelling helps with driver comfort and safety.

 

To minimise soil compaction, it employs a combination of wide terra tyres and an automatic steering mode, which pivots the rear axle toward the desired side, giving a crab motion.

 

A fully hydraulic pivoting rear linkage maintains straight travel of the slurry application implements, and injection equipment can be pressurised to increase ground penetration.

 

The new Comfortcab features a 12.1inch touch screen terminal and integrated functional arm rest with a new joystick design plus a ‘Jog dial’ to control the terminal.

 

Driver comforts include automatic climate control, an ‘active’ seat from Grammer plus upgraded noise insulation to give in cab levels of 61dB.

 

The Terra Variant’s headland management system automatically performs pre-programmed headland settings, such as crab steering, lowering the linkage, slurry pump on/off and activating the torque drive.

Machines are delivered ‘Trimble Ready’ to utilise guidance control and a range of customised Trimble-based systems can be specified, with accuracy levels from 3-30cm.

 

In addition to manure application equipment, the Terra Variant can now be fitted the new Multi-bunker MB35 which can also be used to harvest maize and wholecrop silage as well as beet.

 

This development has led to the addition of the option of Michelin Cerex Bib 1000/55 R32 CFO tyres to improve performance in difficult conditions, which also benefits muck and slurry applications, says the manufacturer.

 

Holmer’s partners are Bergmann for solid manure application equipment and Zumnhammer for liquid applicators.

 

The Zunhammer liquid system has a tank volume of 21cu.m and a Vogelsang pump system, and can inject 25cu.m/ha to give daily outputs of up to 160cu.m/hr along with incorporation.

 

Filling is achieved while the engine is idling, reducing fuel consumption, via a 5.70m-long suction pipe which can be pivoted 170deg to the side.

 

All major functions can be controlled via the in-cab joystick, with fully automated regulation of spreading volume through IsoBus controls.

 

Bergmann’s solid manure spreaders are available in 26 and 30cu.m capacities with spreading via a slat and chain conveyor to twin horizontal rotors and 1,200mm diameter discs, giving spread widths up to 30m.

 

Six integrated weigh cells offer monitoring and application recording capability.

The Claas Xerion is now available with an extended range of muck and slurry application equipment with the introduction of a new higher capacity, lightweight vacuum tank system from SGT and a new solids spreader body from Tebbe.

 

The Xerion 4000, which has a maximum power output of 435hp, is available in a Saddletrac version, where the cab is located at the front leaving a large carrying area at the rear. It comes with an Eccom 5.0 continuously variable transmission (CVT) with a top speed of 50kph and has an auxiliary output for high flow hydraulics, required for high output slurry tankers.

 

“The Xerion is suited to high torque applications which allows heavy duty injector/incorporating implements to be used on the rear, which is particularly important when being used with the SGT tanker system,” explains Claas Tractor product manager Alastair McCallum.

 

The Tebbe demountable body has a total capacity of 13.2cu.m and is manufactured from 3mm thick steel. The load is conveyed to the rear spreader on two heavy-duty hydraulically driven steel conveyor belts.

 

At the rear of the spreader body there is a large slurry door and the material initially passes through two horizontal beaters driven by Duplex chains, before dropping onto two one-metre diameter spreading discs.

 

Claas says that compared to other self-propelled spreaders on the market, the Xerion 4000 Saddletrac with its forward positioned cab has a shorter overall length, and the four-wheel steering makes it extremely manoeuvrable.

Specialist tanker manufacturer SGT has introduced a new higher capacity system specifically designed for the Xerion 4000 Saddletrac.

 

Compared to the previous 14cu.m steel tank designed for the Xerion 3800 Saddletrac, the capacity of the new tank system has been increased to 16cu.m to take advantage of the Xerion 4000’s longer wheelbase. The new tank is made of polyester, which reduces weight by 1,800kg, allowing for a higher load capacity.

 

It is filled using a front-mounted 10inch docking system and features a 10inch stonetrap box, hydraulic macerator and a 9,000 litres/minute Vogelsang pump. To further increase capacity, reduce filling time and allow for higher outputs when using 24-36m booms, a 12inch docking pipe and 12,000 litres/minute pump system is available.

 

SGT has also designed a new mounting system for the pump unit, for use with Xerions specified without a front linkage. This has the benefit that it is 900kg lighter, so places less weight on the front axle.

 

The tank system can either be used as a stand-alone unit, or in combination with an additional 16cu.m trailed tanker, giving a total capacity of 32cu.m.

 

Dribble bar spreading options available with the SGT tank system include 18m wide Vogelsang Kompact or Bomech bars ranging in width from 9.0m up to 21m.

 


Vervaet

Vervaet

Vervaet, distributed in the UK via J Riley Beet Harvester, has introduced a new Hydro Trike range, with 40 machines currently in production for delivery in February. It adds new styling and engine layout, plus a DAF MX340 engine.

 

It is available in two main models – the standard three-wheel Hydro Trike and the higher-capacity five-wheel Hydro Trike XL version with an additional axle.

 

The current model is powered by a 12.9-litre DAF unit which produces 465hp at 1,400rpm. When full power is not required this is further reduced to 1,250rpm, providing additional fuel savings. Drive is hydro-mechanical, infinitely variable within two ranges and top speed is 40kph.

 

Tyre pressures for the 1,000mm wide front tyre and 1,050mm rear tyres can be altered between field and road work on-the-move using a central tyre inflation system. On the XL model the additional axle, fitted with 750mm wide tyres, can be extended so that each wheel follows a different track while in work. The load on this axle is automatically varied according to weight of the payload, although this can also be set manually if required.

A new Panien UW spreader body has been built specifically for the Hydro Trike XL. It has a capacity of 20cu.m and uses two heavy-duty floor chains which are driven from both sides and can be reversed to clear blockages. Spreading is via two beaters and two large-diameter discs, to 24m. A border deflector is used when spreading headlands.

 

Liquid slurry systems are produced and fitted by Vervaet with 14,000 or 16,000 litre capacities available for the standard three-wheel Hydro Trike, and 19,000 litres for the five-wheel version. All tanks are filled in less than three minutes using a side-mounted suction arm. A stone trap in the intake system prevents damage to the hydraulically-driven high-capacity Borger slurry pump.

 

The Hydro Trike can be fitted with a variety of rear injector tools on the category 3 quick-couple rear linkage, from disc injectors for working in grassland and growing crops to cultivator injectors for working in stubble.

Vervaet’s Tri-Control colour touch screen computer provides rate control to match forward speed using load cells in the Panien spreader body to measure product density.

 

For liquid applicators, the desired rate is set in the system, and the computer varies the application proportionally according to the machine’s forward speed to apply the correct amount.

 

GPS steering systems can also be used for further levels of precision.

 


Vredo

Vredo

Vredo’s latest self-propelled Trac machine, the VT4546, is powered by a 450hp Deutz 12-litre V6 engine driving via a continuously variable hydraulic-mechanical transmission, with a top speed of 40kph.

 

The four-wheel VT4546 has been designed to give even weight distribution between the front and rear axles, allowing low tyre pressures to be used all-round.

 

The cab is attached to the very front of the machine so that any tank construction or manure spreader can be optimally positioned.

 

Export manager Age Krug explains: “The Vredo Trac has the lowest weight, and therefore an excellent load capacity, and its crab steer reduces ground pressure. It is also very comfortable to operate due to the suspended front axle, Claas Vista cab and the centrally placed engine, which reduces noise.”

 

Its new cab features a console integrated into the driver‘s seat with joystick control. All vehicle and system information is displayed by a 10.1inch colour touch-screen terminal display.

A choice of two-wheel, four-wheel and crab steering reduces compaction and maximises manoeuvrability. At 3m wide with 1050/50R32 tyres, the VT4546 has all-wheel drive and lockable differential.

 

The liquid slurry version features a 19,500 litre polyester tank with 9,000 litre/min. slurry pump with 8 or 10inch reload arm with turbo-pump.

 

The Vredo Slicing Filter mounted in front of the pump ensures that all large particles are reduced in size and that all foreign objects are filtered out of the slurry. This prevents damage to the pump and protects the entire system from clogging up, says the manufacturer.

 

Its three-point linkage with category three coupling is automatically steered when the machine is in crab steer.

Vredo also supplies its own disc slurry injectors, in widths up to 12m with a double disc system for easier ground penetration.

 

The VT4546 can also be fitted with a mechanically driven Tebbe muck/sludge spreader with a capacity of 18cu.m/20 tonnes. Pto mechanical drive gives a constant input speed for a more even spreading pattern and low fuel consumption, claims Vredo.
