Kubota Engines

Kubota’s® high quality and eco-friendly engines satisfy all global emission regulations.


As the world demands stricter environmental protection, engines are required to meet stricter emission regulations. The Engine Product Environmental Management Section (EPEMS) at Kubota Corporation in Osaka, Japan, was established exclusively to work on environmental issues. By gathering information concerning emission regulations from all over the world, sharing and analyzing it within the company, and performing thorough computer-controlled automatic emission measuring tests on all new engines, this division is taking all possible measures to ensure that the engines produced by Kubota possess the world’s highest level of adaptability to pass future emission regulations.


At Bay City, we provide a full line of genuine Kubota OEM replacement parts, as well as complete Kubota engines for sale.

Kubota’s quality inspection facility maintains the world’s highest emission-level controls.


Kubota Corporation’s Quality Inspection Facility is state-of-the-art. This facility is designed to ensure that all Kubota engines clear future, more stringent emission regulations. Newly developed engine models first must pass certification tests for all existing emission regulations. Once they pass these tests, the newly developed engine models move into mass production. Thereafter, regular sampling inspections reconfirm that they meet the high quality expectations of the Kubota name: high reliability, clean performance, and large capacity.

Kubota Diesel Engines


Tier 4 Engines


The Environmental Protection Agency has multiple tiers of emission standards for engines. Kubota manufactures engines according to Tier 4 standards, which require the use of advanced control technologies that are designed to decrease emissions by 90 percent. These technologies include Diesel Particulate Filter (DPF)*4, Common Rail System, Exhaust-Gas-Recirculation Device (EGR)*3, and an electronic fuel injection system. Along with better emission performance and efficiency, building Kubota engines in accordance with Tier 4 standards results in easier installation, greater durability, and quieter operation.


Spark Ignited Series


The WG, DF, and DG Series are Kubota’s solutions for customers who want the rugged reliability of diesel with the convenience of gasoline, LPG, or natural gas. Based on the legendary Super Mini Series, Kubota’s gas offerings combine compact power with flexible fuel choices.

Kubota Generators


Along with engines, Bay City carries the full line of GL Series generators from Kubota, including the LOWBOY II Series. In addition to quiet and clean operation, Kubota single phase generators are sold with power output capabilities of 7 kW to 11kW.


These generators are designed to have the minimum possible height while using vertical diesel engines. This is achieved by direct coupling of the engine crankshaft with the cooling fan. Since they require less space for operation, the range of possible applications has been greatly increased. The GL series Kubota generators offer the following benefits:


  • Simple, one-side maintenance
  • Safety
  • Longer continuous operation
  • Easy transport
  • 2-Pole Single-Phase Output Range: 6.5 ~ 10.0 kVA
