IT certainly was a rewarding Agritechnica for John Deere and Joskin who won the only gold medal at the show for their joint venture revealing the world’s first continuously variable transmission with electro-mechanical power split including an implement interface.

Now that implements and their prime movers can ‘talk’ to each other via various links (Isobus being the most common), this looks set to be one of the areas that machinery will see lots of change. This innovation is proof of that.

On its medal-winning debut at Agritechnica, it was shown on a 25.5 m3 Joskin slurry tanker, equipped with two drive axles powered by a 100 kW electric motor.

The drive axles allow a significant traction increase and thus a significant slip reduction which, in turn, reduces soil damage. The motor is powered by a standard AEF ISO socket and the additional drive can also be used for other implements and trailers.

This technology will also allow smaller, lighter tractors to pull wider implements and injectors, which increases the productivity and keeps investment costs down.

For its new eAutoPowr transmission, John Deere has completely replaced the hydraulic components with an electric power path. The two brushless electric motors are virtually wear-free and powertrain durability exceeds any other concepts previously offered in the industry. In addition, maintenance costs are significantly lower.

Another selling point is increased efficiency, especially in the partial load range. As a result, the already unique fuel efficiency of the 8R tractors could once again be increased. The driver also benefits from the fine speed regulation and better acceleration behaviour.

An integrated power management system ensures the transmission has high engine power without overloading the mechanical drive train, and clutch wear is permanently monitored, and the clutch is calibrated adaptively.

For driving implements and trailers, the eAutoPowr can provide up to 100 kW of electrical power. There are 700 V DC (DC) or 480 V frequency variable three-phase alternating current (AC) available.

This makes eAutoPowr the first transmission to offer a cost-effective and efficient electrification solution for intelligent tractor-implement combinations with merged power generation and propulsion.

New slurry tanker range launched by Samson

WITH numerous fill points to choose from, the new TG slurry tankers from Samson have already stirred up a lot of interest.

The two models, the TG18 and TG20, have respective capacities of 18 and 20 cubic metres.

These tankers are not as heavy as they used to be, given that the operating vacuum is only generated in the ejector pipe system and not in the entire slurry tanker, which helps to minimise the amount of steel used in the TG tankers.

The ejector system can build up a very high vacuum – under optimal conditions down to -0.9 bar – and has a filling capacity of up to 6000 litres per minute.

The Samson TGs can have multiple filling points, either via a hopper placed at the top of the tanker, hose with filling pump on the side of the tanker, via single or double articulated side arms, or via a front arm pump.

Tankers can also get the addition of a Samson hydraulic three-point hitch with a lifting capacity of 3.8 tonnes

New Joskin Roadliner

on the way

A new Roadliner slurry tanker was on show at Agritechnica, from Joskin, with its dolly turntable axle system.

This model extends the Tetraliner range designed to help farmers and contractors who have to transport slurry long distances.

The dolly system comprises an axle on a turntable that is directly integrated in the tank.

Thanks to its dolly, the Roadliner allows a total load up to 34 tonnes, with a maximum 10 tonnes on each axle and a four-tonne maximum weight on the eyelet depending on the tractor type.

They can be fitted with road tyres 400R22.5, but also with wider 560/60R22.5 tyres with many different profiles in order to adapt the tanker to any kind of terrains and conditions.

A MEC8000/D vacuum pump is part of the standard equipment located in the V-shaped drawbar.

The model on display was the 26,000-litre version but other capacities include 21,000 litres, 23,500 litres and 28,000 litres.

Annaburger reveals new tri-axle tanker

GERMAN maker, Annaburger, has recently introduced its new Tridem slurry spreader, the HTS 34.28 Profi tanker which is designed for agricultural contractors and large farms.

The fibreglass trailer has a low dead weight and therefore offers a high filling volume. The chassis, with 41-tonne BPW axles, can be fitted with size 750/60 R30.5 tyres.

The electronic forced steering in the first and third axles makes the vehicle particularly soil-friendly when it travels on arable land, or turf. On the road, the cylindrical shape of the tank and four integrated baffle plates reduce unwanted surging of the liquid.

A particular benefit is the option for rear-mounting a four-point suspension for a linkage weighing up to 4.5 tonnes, for example a 36m wide Vogelsang dribble bar.

The high-performance Vogelsang rotary piston pump system, with a capacity of up to 9000 litres per minute, guarantees short filling times and large application volumes.

Brantner offer huge ‘Power Push’ spreader

WHEN it comes to spreading manure in large quantities, the Austrian-built Brantner TR34090 Power Push model is one answer.

With a gross weight of 34-tonnes and a deadweight of 10 tonnes, a payload between 43 and 49 cubic metres is possible.

The maker claim that an extremely strong chassis frame, made of double C press profiles, gives the tanker extra stability in the field and on the road.

Sitting at 11m long and 3m wide, even when fitted with the biggest tyres, this giant of a machine is designed to shift manure in quantity.

The distance between axles is 1.8m and tyre choice is 560/60 R 22.5 Agri Radial Mitas 161 D.

Rolland rolls out the new Rollforce spreader

WITH a 22 cubic metre load Rolland’s new Rollforce 7322 manure spreader is now the largest in the company’s range.

It has 1.55m high sides built from reinforced steel to allow the spreader to be easily loaded. It runs on two axles that can either be fixed, or come with a steering capability to reduce scuffing.

A length of 7.3m is seen as optimal for large volume buckets, thus allowing a very fast loading.

The braking system can either be air or hydraulic or mixed and the drawbar can be adjustable or with springs.

There are a number of optional extras that can be fitted to the Rollforce 7322 such as the DPAe electronic control unit, a proportional electronic feed rate that continuously adjusts the speed of the belt to the tractor speed to improve driver comfort and work precision, and also onboard weigh scales and a camera.

Reducing soil compaction with Vervaet

DUTCH company, Vervaet, exhibited its five-wheel-drive Hydro Trike at the show which reduces soil compaction when spreading heavy loads of manure.

The latest version has a driven mid-axle and is powered by a Paccar 530hp engine. The extending drive axles offer 135hp when fully extended which aids the machine when travelling over wet ground and helps increase stability when working on slopes.

The extra power is provided hydraulically by a 175-litre per minute pump, with axles pushed out when in the field giving a full width of 4.5m.

There’s also a new three-point suspension system to replace the leaf spring, with repositioned shock absorbers at the front of the axle.

An inclination sensor, which detects whether the machine is on a side-hill, allows the system to automatically lock the suspension on the ‘down’ side.

Fitted with huge 1000/55 tyres on the front and rear, and 750/50 tyres on the extendable mid axles, soil compaction is greatly reduced.

The trike can reach its top speed of 40kph with the engine running at just 1200rpm rather than at 1400rpm.

Tebbe launches new universal spreader

WITH a payload of 13.5 tonnes, the new Tebbe KS260 universal spreader is big enough for most farms in Scotland.

A loading height of 3m ensures a decent cargo can be transported but also that machines can reach it easily.

When full, this trailer weighs 24 tonnes and has two rolling floors with four hardened round steel chains of 14 x 50 mm with a breaking load of 24 tonnes per chain strand.

At the rear there are gimbal-driven milling drums for perfect shredding and a tapered load compartment to make sure all the material is dispensed.

Keeping the machine on the road are 710/50 R 26.5 tyres, with a 10-point wheel connection.
