- Proven Reliability and Technology: The latest technology and strong performance-two things customers expect from Kubota engines. We continue to provide both of these through the pursuit of excellence in three key areas: emissions compliance, progress towards fully electronic-controlled engines, and flexibility in the products and services we provide to customers worldwide.
- Clean and Quiet Power: A common rail system has made it possible to optimize combustion and create a more durable and quieter engine with higher fuel efficiency. By meticulously screening and controlling the exhaust gas aftertreatment components (Diesel Oxidation Catalyst [DOC] and Diesel Particulate Filter [DPF]), we are able to offer a clean and high-performance engine.
- Emissions Compliance: Meeting rigid emissions regulations can be a challenge for any company. D1803-CR-E4B engine have been designed to comply with stringent regulations: EPA / CARB Tier 4 + EU Stage IIIA. In addition, innovative emissions solutions, such as the use of aftertreatment units, have also been integrated into the 03 Series engines.
- Flexibility: Flexibility is a must when working with customers in different countries who have different engine needs. Since Kubota 03 Series engines have evolved along every step in meeting the requirements of each EPA Tier, we are able to provide our customers worldwide with engines certified for the appropriate emissions regulations. In addition, we have designed aftertreatment units with minimum impact for easy installation.
- Trust: The Kubota 03 Series is the ideal solution for your companyâ€™s global marketing strategy. We continuously strive to meet your needs with the experience and expertise that is your due.
