For customers who prefer stepless transmissions for infinite speed control and ease of drivability, the new EVT will be available for all 410-horsepower 8 Series Tractors including 8R, 8RT, and 8RX models.

“An EVT has electric motors in place of the hydrostatic motors that improve transmission performance, reliability, and increased efficiency. The EVT brings everything customers appreciate from an Infinitely Variable Transmission (IVT), into higher horsepower 8 Series Tractors. Inherently, the electrical components of an EVT are extremely reliable, offer tremendous longevity, and provide better overall tractor control, along with a system built for easy serviceability and diagnostics. In addition, customers will notice an EVT operates more quietly than an IVT.”

said Ryan Jardon, marketing manager for John Deere.

As farmers look to the future, the EVT will likely be the transmission of choice for customers going forward according to Jardon.

“In the future, EVT-equipped 8 Series Tractors, will optionally feature electric power generation capacity of offboarding electricity to power implements. This EVT is the industry’s only transmission that enables electric power generation (up to 100kW). By using this electricity farmers could power implement fan drives, take the place of implement hydraulic pumps, or assist the tractor by powering the implement’s axles. This is similar, to the proven technology John Deere currently uses, on construction equipment.”

Jardon said.

Agricultural implements with powered axles are already successfully used in Europe to help push the tractor from behind while working in the field.

“EVT technology offboards electricity from the tractor to provide added power to the implement and can reduce wheel slip, improve up-hill performance, and enables the tractor to pull wide implements without the need for extra ballast or a larger tractor,”

Jardon said.

For MY 23, John Deere 9R 640 and 9RX 640 Tractors will now also be powered by the all-new, completely redesigned JD14X diesel engine producing 640-rated horsepower. MY 22 390- to 590-horsepower 9 Series Tractors also use this engine across the entire lineup of 9 Series Tractors, including the 640-horsepower models. Based on internal testing, the JD14X engine in 9R 640 and 9RX 640 Tractors uses 7% less fuel than previous models.

“These new engines were built for outstanding performance, greater reliability and we have made them easier to access and service. The engine features a 500-hour oil change interval, hydraulic fan drive, and a high-pressure common-rail fuel delivery system for increased fuel atomization, efficiency, and power, along with faster start times. Customers told us they appreciate the lugging capabilities the new engine has brought to their 9 Series Tractors.”

Jardon said.

Developed three years ago by Naïo Technologies, a pioneering company in agricultural robotics, Ted is the first autonomous, 100% electric high-clearance tool dedicated to the mechanical weeding of vines. The robot has quickly generated strong interest in the wine-growing sector, which is looking very closely at this solution.

More than twenty Teds are now working in various vineyards. This high-clearance tool, capable of working autonomously among the vines, responds to the sector’s current needs. Ted limits soil compaction and thanks to its mechanical weeding will allow the elimination of allow chemical weedkillers, while still remaining environmentally-friendly thanks to its entirely electric operation.

The robot is therefore continuing to improve in the hands of its wine-growing experts in terms of reliability, autonomy and safety.

“The Bernard Magrez Estate is convinced that robotisation will play a fundamental role in the mechanical maintenance of the land over the next few decades. Electrical power, the absence of greenhouse gas emissions and noise pollution are the main focus of our commitment to the environment. In this, we have developed a 4-year partnership with Naïo Technologies to perfect a robot capable of carrying out the majority of the soil maintenance work among the vines”

highlights Arnaud Delaherche, R&D Manager of the Bernard Magrez Estate.

This confidence is reinforced by a common desire to promote an innovative, technological solution already in existence and to prepare it for tomorrow: the Ted robot.

“Within the context of its commitments on sustainable wine growing and to support its partner wine producers, the Hennessy company is testing many different solutions in its vineyards to promote more virtuous wine growing. The R&D partnership project with Naïo Technologies is fully compatible with this approach. The development of the Ted robot is therefore an innovative alternative to the use of weedkillers. Its light weight and adaptability, as well as its electrical operation, are assets in view of the development of sustainable wine growing in the Charente region,”

specifies Mathilde Boisseau, Hennessy Vine and Wine Manager.

From July onwards, they will be the first ones to test the new version of the Ted robot before its official launch planned for September.

Having the option of feeding square, as well as round bales with one single machine gives your operation the freedom of choice when buying in bales, which means you are not restricted by the availability of one type of bale, while being able to make a price conscious decision to fit your business. Especially in drought conditions where prices are high and bales are scarce, this can be an unbeatable advantage.

Main Benefits

The Hustler Chainless bale feeder feeds out square and round bales simply by adjusting the platform to the right position. The robust frame is able to handle bales of up to 1,250kg weight. The design is compact and light enough to fit into narrow barns. 3-point linkage, as well as loader, skid steer and telehandler mount options are possible and make this feeder perfect for feeding into troughs and hay racks.

Easy Loading

Our patented Snaplox System is a hands-free auto connection and disconnection system that lets you disconnect the feeder by simply lowering it onto the ground. No more pulling on a rope and twisting your back.

1. Disconnect the Cradle
2. Load Bale
3. Feed Bale

The integrated tynes mean the unit is suitable for a single tractor operation and the low cradle design makes loading bales simple. Once the bale is ready to be fed out, Snaplox automatically locks when reconnecting the headstock to the feeding cradle, for guaranteed safety.

Features

The headstock can easily be connected to the feeding cradle thanks to the unequal length tynes and large guide cones. The powerful 3:1 rotors of the Hustler Chainless bale feeder gently tease apart the bale to preserve the nutritional leaf, which makes the feed more palatable for your stock and minimizes feed wastage. The all hydraulic system means, there are no chains that can snatch or derail. The result is increased reliability, lower maintenance and a silent operation.

Every day and for many years, the cable railway traveling in the Tyrolean Alps to the top of Zugspitze has been carrying hundreds of people to an altitude of 2,964 metres. At a speed of 10 metres per second, the trip takes about seven and a half minutes, powered by two electric motors of 500 kW. In the driver’s cab, control of the current motor status – slow, idle, forward, reverse, accelerate, high-speed and brake – requires a high level of accuracy and reliability by the speed control system. After all, passenger comfort and safety are first.

However, the components in mountain railways are exposed to harsh conditions: wind, rain and snow shape the ambience, temperatures range from double-digit minus degrees in winter to high plus degrees in summer. A perfect application example for the HeavyDuty tacho generators from Baumer Hübner, here analog tachor generator TDP 0.2 LT which is a particularly robust and precise speed sensor variant. What exactly does “HeavyDuty” mean?

HeavyDuty as encompassing performance promise

“HeavyDuty means “heavy-duty”. To Baumer Hübner, however, this is much more than thick-walled housings and corrosion protection. HeavyDuty is the encompassing promise of never letting users down thanks to reliable performance for many years. A prerequisite particularly in mountain railway applications. To ensure this, some specific criteria must be met:

Mechanical robustness of course is key. Tacho generators in mountain railway drives must withstand shocks, vibration and other impacts the rotating shaft is exposed to for many years, without losing any of their functionalities. After all, product exchange is expensive, not because of tacho pricing but because of installation in places difficult to access and system downtime during exchange. Robust housings with solid walls are a good start, so TDP 0.2 LT comes in a die-cast aluminium housing and with stainless steel shaft. But also the interior must be protected against shocks and vibration. TDP 0.2 LT with bearings at both shaft ends is capable of enduring high radial and axial shaft load.

HeavyDuty tacho generators must withstand dust, dirt and moisture which requires a sufficient level of tightness. For this reason, the HeavyDuty housing is well sealed, especially at critical, neuralgic points – shaft and electrical connections. In addition, appropriate materials and coatings protect against corrosion by salt water or chemicals.

Tacho generators do not integrate electronics and therefore are extremely durable against harmful impacts by electromagnetic fields. So, nothing stands in the way for routing live, unshielded cables nearby. Furthermore, shaft currents induced by voltage differences might burn the bearing lubrication which results into bearing destruction. The electrically insulated interior of HeavyDuty tacho generators is therefore well protected against such harmful influences.

Last but not least, precision is another valuable virtue of these HeavyDuty heavy weights. Tacho generators must deliver reliable signals at all times to ensure precise drive control and regulation. Based on the speed information, the controller can identify any drive speed deviation and will intervene. HeavyDuty tacho generators in heavy vehicles such as mountain railways must be as precise as smaller speed sensors. It is not without reason that TDP 0.2 LT is field-tested and extremely reliable. It delivers a 60V output signal already at 1000 rpm; at the maximum operating speed of 10,000 rpm the controller is even provided with up to 600V.

High-precision tachometer voltage throughout the entire speed range

The conventional combination of copper commutator and graphite brushes in tacho generators has long been outdated. The copper oxide layers on the commutator cause irregular transition resistance and thus high ripple in tachometer voltage, so low speed would not be accurately detected. However, graphite with good sliding properties ensures a long brush service life. The combination of copper commutator and silver graphite brushes is much more appropriate for low speed detection, since precious metal brushes apply a highly conductive “patina” to the commutator. However, this solution is sensitive to adverse ambient conditions such as oil, grease or air containing sulphur and salt. Under such conditions no patina would build up and the said good transmission properties would be lost over the entire speed range. In addition, there is increased wear because the metal-containing brushes run directly on the copper layer.

LongLife® is what Baumer Hübner calls their tachometer technology patented in 1987 which combines the positive of above procedures and eliminates the drawbacks. In a special process and depending on the tacho variant, Baumer Hübner embeds one or two massive silver tracks into the commutator surface. The track can be very fine thanks to relatively minor tacho currents. TDP 0.2 LT features even two silver tracks. This ensures permanent low contact resistance even under difficult conditions. And it allows for a 60 mV/min-1 voltage constant of TDP 0.2 LT resulting in a wide detectable speed range from ≤ 0.08 to 10,000 min-1, with both mechanically and electrically limited maximum speed. TDP 0.2 LT therefore provides a dynamic range of 1 : 125,000. The brushes especially modified by Baumer Hübner together, with the LongLife commutator ensure maintenance-free service life that even will exceed that of the ball bearings.

LongLife® even for ski lifts

Ski lifts carrying millions of skiers to mountain peaks every year have likewise tough requirements on drive control. Here too, to ensure passenger safety manufacturers rely on tacho generators that have proven themselves in many applications. They ensure reliable equipment functionality even during severe frost, snowfall and icy winds. Today, speed-controlled drives are also common in ski lifts for smooth starts and variable travel speed. For decades, lift manufacturers have been deploying analog tacho generators by Baumer Hübner such as GMP 1.0. The tacho generator is directly connected to the slowly rotating cable wheel via step-up converter and chain wheel drive. This way, dead speed in the motor gearbox is isolated from the control loop and generates sufficient speed signals even under harsh ambient conditions. The GMP 1.0 also features two silver tracks for permanent low contact resistance and thus a widely detectable speed range with good transmission quality of measured values. The robust design and standard temperature compensation make the tacho generator ideal for use in the harsh conditions of snow-covered mountains.

More than half a century of experience in HeavyDuty tacho generators and encoders has evolved the comprehensive Baumer Hübner portfolio of reliable, precise and durable product variants – from small to large designs. They support all relevant analog and digital interfaces and excel with the capabilities required to withstand even adverse ambient conditions. Application examples like mountain railways and ski lifts clearly prove that for users with high requirements the HeavyDuty Original is the right choice in this encoder class.
