Development of MU5501, Multi-purpose Tractor for Indian Market

Tractor Engineering Dept./Farm & Industrial Machinery R&D Dept. Ⅲ/Vehicle Base Technology Engineering Dept.

India has the world's largest tractor market with a demand of 600,000 units per year. Due to its low tractor penetration rate, further growth of the Indian market is expected. KUBOTA needs to launch full-scale operations in the world’s largest market, India, in order to become a Global Major Brand that can contribute the most to society by being trusted by the largest number of customers. Therefore, we have developed the heavyweight tractor MU5501 suited for Indian multi-purpose uses including high traction. We have frequently visited Indian market and have conducted market-oriented development with different concepts from those of the previous lightweight and compact KUBOTA tractors. Here we show the characteristic way of operating a tractor in the Indian market and how to meet market demand for products with low fuel consumption and high durability.

  • Multi-purpose

Development of Engine System Diagnostic Tool for Global Service

Engine Engineering Dept./Engine Environmental Management & Promotion Dept.

These days, industrial engines are becoming more and more dependent on electronic control systems due to strict emissions regulations.
The functions of electronic control devices differ depending on the level of emissions regulations and engine series. With an increase in the types of such devices, the number of diagnostic tools has increased.
And although updating software to control engines through an Internet connection on-site is useful, it has been difficult to achieve this for security reasons.
In this development, various electronic control systems were easily serviced with one integrated diagnostic tool. In addition, a high level of security has been introduced to encourage users to promptly update software over the Internet in the market for small industrial engines.

Development of Corn Harvester PRO1408Y with Husking Function for China

Kubota Agricultural Machinery (SUZHOU) Co., Ltd. Engineering Dept./Combine Harvester Engineering Dept.

China is the world’s second-largest producer of corn, with 33,540,000 hectares of planted acreage, and a production of about 200,000,000 tons of corn a year. However the rate of mechanization of harvesting work is low at 48 % (2014) and there are expectations that from now on the market for corn harvesters will further expand. In addition, the machines that currently exist in the market and that are made by Chinese local manufacturers have a poor performance and experience many troubles; hence, farmers are requesting high-performance and high-quality machines. Kubota Agricultural Machinery (Suzhou) (hereinafter KAMS) can speedily grasp the market needs and reflect them in its development. And its Technical Development Department has linked up with Kubota’s Harvester Development Department from the design stage and participated in developing work blocks. As a result, we were able to quickly develop PRO1408Y, a corn harvester with a husking function, that meets the market’s requests for high-speed work, reduction of yield loss, high husking rate and low-fuel consumption.

  • Corn Harvester
  • High-speed Work
  • Loss of Yield
  • High Husking Rate
  • Fuel-efficiency

Development of New Power Tiller for Emerging Markets

Kubota Research & Development Asia

World demand for food is increasing along with increasing population. Hence, many emerging countries are starting to mechanize their farm work to increase their crop production capacity so that they can export food and meet that demand. Animals and humans are still the main sources of labor in farm work for most small farmers in emerging countries. This means there is high demand for farm machinery with a good basic performance and multi-purpose functions to help increase the crop production capacity at an affordable price for small farmers. To meet this demand, SIAM KUBOTA Corporation Co., Ltd. (SKC) developed PEM480, a new power tiller for emerging markets. Not only can it meet the above demand but also it can help SKC to enter emerging markets and establish sales and marketing networks to support future business growth for Kubota.

Development of “Non-Stop Baler” Technology

Kverneland Group Ravenna

Non-stop baling for reduced operator stress and fatigue, leading to improved operational efficiency. Increased output: Baling non-stop saves 15-18 seconds for every bale made. During a typical 300 bale day, this can give a time saving of over 1½ hours per day. Compact size: Despite its non-stop capacity, FastBale is smaller than other competitive baler wrappers, ensuring easy field access and stress free road transport. Simple bale transfer system and high speed vertical wrapping system ensure high output and gentle bale release. Fully automatic operation, with animated real time display, keeps the operator relaxed and fully productive throughout long working days.

  • Non-Stop Baling
  • High-Productivity
  • Compact
  • Automatic
  • Time-Saving

Development of Z700 Commercial Zero-Turn Mower

Turf Engineering Department of America

Kubota produces some products to satisfy zero-turn mower estate customers. These products also appeal to zero-turn-mower commercial customers. However, some commercial customers are not completely satisfied. Machine performance, ergonomics, and cost are several areas where improvements could allow Kubota to satisfy the commercial customer more completely. By developing new technologies such as a manually-adjusted deck height system, a machine layout to reduce front axle weight, and easy-to-operate parking brakes, the Z700 has successfully appealed to customers in the commercial market. As a result, Kubota has improved its ability to support the thriving life of humans while still caring for the environment of this beautiful earth.

  • Ergonomics
  • Parking Brake
  • Mower Deck Height Adjustment

Development of Riding Type Rice Transplanter SPV for Overseas

Transplanter Engineering Dept.

Rapid economic development in emerging countries is leading to escalating personnel costs the costs for rice cultivation, too, and making it difficult to secure labor. Consequently, mechanization of rice cultivation in such countries China and so on is taking place. Rice transplanters in emerging countries tend to be used in the following way: the land owner entrusts rice planting to the owner of the rice transplanter, and the land owner pays a fee to the rice transplanter owner in proportion to the transplanted area. The larger the area planted, the more rewards the owner of the rice transplanter will receive. Based on this background, an ability to plant larger area, in other words a ”profitable machine,” is required. To meet this demand, Kubota has developed new rice transplanters based on the concept of ”global 6- and 8-row riding type rice transplanters which are able to produce a prof it for user and have a basic performance.” In this paper, we explain the technical development we conducted to meet three requirements―high efficiency, high durability and ease of maintenance―which are directly related to profitability.

  • Riding Type Rice Transplanter
  • High Efficiency
  • High Durability
  • Ease of Maintenance

Nowadays, with regard to operation and maintenance of water environment infrastructure facilities, energy saving, cost saving, improvement in work efficiency, and longevity of facilities are required, and IoT (Internet of Things) technology is necessary for Kubota to meet the needs of its customers. Kubota has provided services such as the remote pump monitoring system1) and the remote liquid membrane monitoring system through Internet for over 10 years.
The demand for IoT system is increasing from a number of our customers of our business unit divisions of Water & Environment and Electronics. We launched a cross-sectional project and created KSIS, a common platform for the remote monitoring and diagnosis. KSIS connects the products of Kubota with IoT to provide a variety of solutions to many customers.
In this paper, we describe the development of products such as data transmission equipment, the cloud server and the establishment of a network for them through the R&D on technologies for the wireless communication and the security for the cloud server. We also report on our efforts to expand them to the global market.
