Product details
Engine overview
New Kubota D1305-EF03 engine assembly for a build-specific replacement. Kubota's model-specific certification reference identifies this three-cylinder, 1.261 L configuration; match the original data plate and installation hardware before ordering.
The EF03 suffix matters: Kubota lists other D1305-EF trims with different reference speeds and torque figures, so a base D1305 designation alone does not establish an exact match.
Configuration & included components
- Engine model: Kubota D1305-EF03.
- Condition: New.
- Supply scope: engine assembly; confirm the included components in the order specification.
- Product code: NYE-KUB-D1305-EF03-N-ENG-S54121725.

Technical specifications
Kubota's 2024 certification attachment identifies the D1305-EF03 reference trim below. Certified reference figures are not a measured test of the particular supplied assembly; verify its serial and build before relying on a rating or emissions approval.
| Specification | Manufacturer reference |
|---|---|
| OEM model code | D1305-EF03 |
| Configuration | Inline three-cylinder diesel (D1305-EF03 certification reference) |
| Displacement | 1.261 L (D1305-EF03 certification reference) |
| Peak-power reference | 18.2 kW at 2,600 rpm in Kubota's 2024 certification entry; not a supplied-unit test result |
| Peak-torque reference | 78.9 N·m at 1,700 rpm in the same certification entry |
| Fuel-injection family | Indirect fuel injection in the certified D1305-EF family |
| D1305 family bore × stroke | 78 × 88 mm in Kubota's separate D1305-E4B reference; confirm against the offered build |
Technical details
The EF03 trim is separately identified in Kubota's certification list. The EF01, EF02 and EF04 rows use different reference operating points; carry the entire suffix through a replacement comparison instead of treating the D1305 family as interchangeable.
Kubota's D1305-E4B industrial reference describes a naturally aspirated, water-cooled, indirect-injection 05 Series engine with an in-line pump. That is a related family configuration, not proof that every part or emissions component of this EF03 supply is identical. Confirm the actual fuel system and external hardware from the offered engine details.

Buyer guide
- Photograph the original block serial and obtain the Illustrated Parts List showing the complete D1305-EF suffix; Kubota says the full model name is not stamped on the engine.
- Check flywheel and bellhousing pattern, mounts, oil pan, cooling outlets and accessory drive against the offered assembly.
- Compare the original governor setting, electrical system, fuel equipment and emissions label with the required operating duty.
Buying questions
Why does the EF03 suffix matter?
Kubota lists EF03 as a distinct D1305-EF trim with its own reference speed and torque figures. Use the full suffix and serial for the replacement review.
Does this page certify the supplied engine's emissions status?
No. The linked document describes Kubota's certified 2024 reference family. The supplied engine's own label, serial and destination requirements must be checked separately.
