Yanmar Agribusiness launching Upgraded Robot Tractor Series in Japan

Japan—Yanmar Agribusiness, Japan based company has announced the upgrades of its autonomous tractor series—capable of autonomous work.

This new versions Tractor can fully or partially autonomous work will go on sale in Japan from April 1st, 2021.

According to press release, this upgrades Robot Tractor suggested retail price before tax will be JPY 10,925,000~14,275,000.

In recent years large scale farming in Japan increasing—brought on by consolidation of smaller farms into larger enterprises.

At the same time, a declining and aging farming population has led to workforce shortages in Japanese agriculture. The market for autonomous agricultural machinery is rising to meet these challenges.

Yanmar’s upgraded robot-auto tractors will utilize a multi-frequency antenna for stable connection and higher positioning accuracy towards a safer, even more efficient autonomous tractor.

“Yanmar’s auto tractor and robot tractor have found favor in the farming community for their efficiency, reliability and accuracy,” said Nagamori Masuda, Yanmar Agribusiness president. “With these new models, Yanmar offers farmers even more value with more robust positioning technology that allows even greater flexibility in the field.”

Yanmar will continue to work to meet customer’s needs, contributing to a sustainable agriculture, President address.

Inaddition, newly design Automated Tractor included features like Multi-frequency antenna for faster positioning, VRStype, greater convenience through expanded RTK coverage and Lower speed (min: 0.5 kph) allows precision work.

Multi-frequency antenna for faster positioning

By receiving signals at three different frequencies from the GNSS satellite, the multi-frequency antenna can ensure safe driving even if the signal is interrupted on one of the frequencies. In addition, the positioning time is reduced by 75% allowing work to commence soon after arrival at the field.

VRS※ type, greater convenience through expanded RTK coverage

Previously, by receiving both signal from the GNSS satellite and a correction from a base station, it was possible to achieve precision of ±3cm.
The new system receives a multi-frequency signal allowing the tractor to receive local reference point positioning data to determine its position via VRS. This means it is no longer necessary to install a Yanmar base station and the system can be used anywhere mobile signal is available.
※VRS (Virtual Reference Station) Requires use of a correction signal service.

 Lower speed (min: 0.5 kph) allows precision work

Increased positioning stability allows for new kinds of work. Because the positioning of the tractor is highly robust, it is possible to carry out precision work at lower speeds as low as 0.5 kph. Previously inaccessible tasks such as combined tilling and ridging can now be carried out by the robot tractor.
