Kubota D722 Diesel Engine, New Super Mini Series (Tier 4 Final)

Complete new genuine Kubota D722, the 0.719 L three-cylinder diesel from Kubota’s Super Mini Series. In its current D722-E4B generation it delivers up to 20.0 HP (14.9 kW) at 3600 rpm and meets EPA/CARB Tier 4 and EU Stage V with no DPF and no electronic aftertreatment, using Kubota’s proven E-TVCS indirect-injection combustion and a simple mechanical in-line injection pump. At just 63 kg dry, it is the engine behind Bobcat mini track loaders and compact excavators, Grasshopper diesel mowers, sub-compact tractors, and a wide range of light construction and turf equipment.

Application & Fitment

Confirmed applications for the Kubota D722 engine family include:

• Bobcat MT50 and MT52 mini track loaders (Bobcat supplies factory 20 HP Tier 4 D722 builds for these machines)
• Bobcat compact excavators 319, 322, E10, and E16 (10.2 HP Tier 4 / Stage V factory spec)
• Grasshopper 721D diesel zero-turn front-mount mower
• Kubota B7300 sub-compact tractor and Kubota GB14
• Woods 6215 mower
• Avant Tecno 320, 420, and 520 compact articulated loaders
• Current-production micro excavators such as the Mechmaxx MEC12 (1.2 ton)

The D722 is also commonly used in MultiQuip, Ariens, Jacobsen, SkyJack, Wacker Neuson, and Vermeer equipment; call to verify your specific machine. A note on generations: many of these machines originally shipped with earlier D722 versions (E2B/E3B). The D722-E4B is the current Tier 4 Final production engine, and Kubota states it keeps the same performance and physical characteristics as the E3B so it transitions into the same OEM applications. Kubota builds the D722 in application-specific spec numbers (KEA stock specs such as D722-E4B-KEA-2 plus OEM specs), so have your engine spec plate or your equipment make, model, and serial number ready and we will match the exact build.

Frequently Asked Questions

Will this fit my machine if it originally came with an older D722?

In most cases, yes. The current D722-E4B keeps the same footprint and performance as the earlier E3B generation by design, and OEMs like Bobcat ship Tier 4 D722 builds for machines that originally used older versions. Because Kubota builds the D722 in many application-specific configurations, call us with your equipment make, model, and engine serial number and we will confirm the exact spec before you order.
