Description:
The Kubota BLADE, EXT. R (KU-RG13874430) is a genuine OEM right-hand blade extension engineered to increase grading width, improve material control, and enhance blade performance on Kubota compact excavators. Specifically designed for demanding excavation and landscaping applications, this heavy-duty extension helps operators move more material efficiently while maintaining smooth and accurate grading control in challenging job site conditions.
In addition, the RG13874430 extension actively expands the right-hand side of the excavator blade assembly, allowing wider grading coverage during leveling, trenching, backfilling, and site preparation work. As a result, operators can complete grading tasks more efficiently while achieving cleaner finishes, improved surface consistency, and better overall machine stability.
Furthermore, Kubota manufactures this blade extension from high-strength steel to withstand repeated impact, abrasive soil conditions, gravel, and continuous heavy-duty operation. Consequently, the extension maintains reliable structural integrity and dependable performance even in harsh construction and earthmoving environments. At the same time, its durable construction helps minimize wear and extend service life under continuous use.
Moreover, Kubota engineers the RG13874430 blade extension to exact factory specifications, ensuring direct OEM fitment and seamless integration into compatible blade systems. Because of its precision-built design, the extension installs securely without modification and maintains proper alignment for stable and efficient grading performance throughout operation.
