Title:
BLADE(EXTEND,LH) (KU-RA05174420)
Description:
The Kubota BLADE (EXTEND, LH) (KU-RA05174420) is a genuine OEM left-hand blade extension designed to increase working width and improve grading efficiency on Kubota compact excavator blade systems. Kubota engineers this component to actively extend the blade’s reach, helping operators move more material per pass while maintaining stable, precise control during excavation and landscaping work.
This LH extension strengthens the blade assembly by improving side coverage and supporting smoother material flow. It performs reliably in harsh ground conditions, including compacted soil, gravel, and general construction environments, where durability and accuracy matter most.
Model Fitment:
The KU-RA05174420 LH blade extension is commonly used on Kubota compact excavators equipped with dozer blade systems, including:
- Kubota K008-5 compact excavator
- Kubota K008-3 (select configurations)
- Other Kubota mini excavators using RA051-series blade assemblies
This extension typically works alongside RH blade, LH blade, and matching extension components to complete the full grading blade setup.
✔ Verified compatibility includes K008-5 models in OEM listings and parts catalogs
Fitment may vary depending on serial number, blade configuration, and regional specification. Always confirm using your official Kubota parts manual before ordering.
