John Deere Debuts Planting Technology, Electric Excavator
During John Deere’s CES 2023 keynote address, the company revealed two new technologies — ExactShot and an electric excavator — that will help Deere’s customers be more productive, profitable and sustainable.
“Everything we do at John Deere is focused on real purpose and real impact,” said Jahmy Hindman, CTO at John Deere. “This means we’re developing technology that enables our customers to provide the food, fuel, fiber and infrastructure that our growing global population needs.”
ExactShot allows farmers to reduce the amount of starter fertilizer needed during planting by more than 60 percent. The technology uses sensors and robotics to place starter fertilizer precisely onto seeds as they are planted in the soil, rather than applying a continuous flow of fertilizer to the entire row of seeds.
The electric excavator, powered by a Kreisel battery, will provide construction workers and road builders with lower daily operating costs, reduced jobsite noise, enhanced machine reliability and zero emissions, without sacrificing the power and performance they need in a machine.
ExactShot Details ï ExactShot will help farmers be economically and environmentally sustainable as they work tirelessly to grow the food, fuel and fiber that we all rely on. With the global population expected to grow from 8 billion to nearly 10 billion by 2050, farmers need to increase production by 60 percent to 70 percent on today’s arable land. ï ExactShot uses a sensor to register when each individual seed is in the process of going into the soil. As this occurs, a robot will spray only the amount of fertilizer needed, about 0.2 ML, directly onto the seed at the exact moment as it goes into the ground. ï Across the U.S. corn crop, ExactShot could save more than 93 million gallons of starter fertilizer annually and prevent wasted fertilizer from encouraging weed growth or increasing the risk of running off the field into a waterway.
Electric Excavator Details ï Deere’s new electric excavator, powered by a Kreisel battery, will improve reliability, performance and safety in construction. Its use on construction sites will result in fewer moving parts, less noise pollution and fewer emissions. ï Deere acquired a majority stake in Kreisel Electric, which created battery technology for a wide range of mobile and stationary applications. Kreisel’s immersion cooling architecture provides unsurpassed lifetime, enhanced safety and improved performance for battery-powered equipment. ï Kreisel’s charging technology results in faster and lowercost connections to the electrical grid.

Hamm’s new small compactors line — the HC CompactLine series (EPA Tier IV/EU Stage V engines) — replaces the predecessor H CompactLine series with immediate effect.
The new compacts offer impressive gradeability, improved driving characteristics and a comfortable, spacious cab, according to the manufacturer. The 11,023 and 15,432 lb. machines are extremely easy to operate and offer ergonomically optimized workstations. This also makes them ideal for machine rental.
Powerful Drive
With the HC 50i (11,023 lbs., drum width 53.9 in.) and HC 70i (15,432 lbs, drum width 66.1 in.), the HC CompactLine series comfortably meets the requirements for compact earthwork rollers. Permanent all-wheel drive with anti-slip control and drive motors instead of a rear axle form the basis for exceptionally good gradeability and high ground clearance. The developers also have further improved and stabilized the handling with various adjustments to the chassis.
Short Climbers
Both compactors are extremely short. In particular, the HC 70i is the world’s shortest compactor in this weight class, at 14.4 ft. Combined with the three-point articulation and the extremely short wheelbase, this results in very good driving and handling characteristics, ideal for compaction on narrow construction sites.
Easy Operation
No specific language skills are required to operate the HC CompactLine. The logical arrangement, careful design and clear symbols on the operating elements make manual operations straightforward. The back-lit display ensures unambiguous operation, even in the dark. The arrangement of the steering wheel allows a clear view of and easy access to the dashboard.
Good Visibility, Safety, Comfort
In terms of visibility, the small compactors offer very wide fields of vision in the open version or large window areas in the cab. A camera system with a monitor also can be added. High-quality LED work lighting is included as standard in the cab.
All models in the HC CompactLine series offer convenient access to the ROPS/FOPS cab or to the open platform with ROPS, which is available with or without a protective roof and with the option of adding FOPS.
The space offered by the completely redesigned cab with specially curved windows is unique in this market. In terms of ergonomics, the operator also benefits from the versatile adjustable seat system and a seat that can be moved to the side, wide-opening windows and draft-free ventilation.
There also are plenty of storage areas, an optional USB connection and comfort options such as a tiltable steering column and an air-conditioning system.
CO Mode Reduces Fuel Consumption
On the small compactors, a modern engine powers the drives and power units. The compactors can operate with either diesel or HVO fuel. The sustainable machine concept includes environmentally friendly and economical operation in ECO mode. This achieves savings by limiting the engine speed.
The parameters have been selected so that most jobs can be done in ECO mode, without sacrificing compaction power. In addition, the optional automatic engine stop reduces diesel consumption. It automatically switches off the engine under certain conditions, e.g. during prolonged downtime. At the same time, the automatic mechanism takes into account the requirements of the exhaust gas purification with diesel particulate filter (DPF). Variety of Drums
Hamm offers compactors with smooth drums and padfoot drums with vibration. Two-piece padfoot shells can be retrofitted for the smooth drum. Accordingly, Hamm also has a specially designed combination scraper in its range.
The HC 70i also is available with a VIO smooth drum that can compact either with vibration or oscillation. All models of the HC CompactLine also can have a leveling blade added.
Options for Compaction Measurement
Hamm offers the HCM compaction meter for all models of the HC CompactLine, including rollers with VIO drums. The displayed Hamm measurement value provides a gage for the compaction progress.
Hamm has developed the “Smart Doc” app for applications that require continuous compaction control or continuous or layer-by-layer documentation. It is supplied with process data from the machine via a Bluetooth interface. The app displays the compaction status in the form of graphics on a smartphone or tablet. This enables the driver to identify where and to what degree the substrate has been compacted as they work. Points of Interest, Including for Rental Companies
Due to their simple operation, multiple adjustments and numerous options, HC CompactLine rollers are ideal for rental. For example, the rear view mirrors can be easily adjusted and cleaned from the cab via split windows.
Other options useful for rental companies include connection to the JD Link telematics system, the telematics interface for automated transfer of machine data, and the electronic battery isolation switch that protects against battery discharge and theft.

The HC CompactLine series (EPA Tier IV/EU Stage V engines) replaces the predecessor H CompactLine series.
At the beginning of 2022, Wirtgen celebrated the market launch of its completely redesigned generation of compact milling machines. And now, the company presents another innovation. Alongside efficiency and environmental compatibility, the focus is now set on ergonomics again. For the first time, compact class machines can be fitted with a comfort cabin.
The operator’s cabin for the W 100 Fi – W 130 Fi models sets new standards when it comes to ergonomics. It offers the operator a comfortable, low-fatigue workplace and provides effective protection against noise emissions. At the same time, the cabin protects the operator when working in all weather conditions —no matter whether it’s windy, raining, cold or sunny and hot.
The cabin air is cleaned by a filter system and the temperature is controlled by an automatic air conditioning and heating system. The cabin also is constructed as a positivepressure system to prevent the ingress of dirt, dust, and hazardous materials into the operator’s workplace. Regardless of the weather conditions, the operator’s workplace always stays dry and clean, also when transporting the machine.
The cabin protects the operator against environmental influences and provides a workplace designed and constructed according to the latest ergonomic principles. Low-Fatigue Working
Environment Promotes Better Concentration The increased comfort and lower impact of environmental influences inside the cabin effectively reduce stress and fatigue. The cabin offers the operator an attractive working environment with modern control elements and assistance systems that are unique in this class. This assures that important factors that contribute to safety and productivity, such as concentration and physical or mental capabilities, are not impaired in any way.
The consequences of this are motivated operators, job satisfaction and maximum occupational health and safety. All in all, the best prerequisites for making every day a productive working day, Wirtgen said.
Problem-Free Communication
The comfort cabin for compact milling machines also shows another of its unique strengths when it comes to communication.
The ambient noise level is so low that the operator can make hands-free phone calls from the cabin. For communication on the construction site, the operator can either use a radio headset or open the easily accessible side window to talk with the crew on the ground.
Enclosed Cabin Prevents Vandalism When closed and locked, the operator’s cabin and all control elements are securely protected against vandalism. There is no longer any need to remove and stow protection covers or open up fold-away control panels at the start of work or vice versa at the end of the working day.
