BLADE LH (KU-RA13974423)
Description:
The Kubota BLADE LH (KU-RA13974423) is a genuine OEM left-hand blade component engineered to deliver dependable grading performance, precise material control, and long-lasting durability in demanding excavation environments. Specifically designed for Kubota compact excavators, this heavy-duty blade helps operators maintain smooth and accurate grading performance during trenching, landscaping, backfilling, and site preparation work.
In addition, the LH blade actively supports the excavator’s dozer blade assembly by directing and controlling material flow along the left-hand side of the machine. As a result, operators can achieve cleaner grading lines, smoother surface finishes, and improved stability while working on uneven terrain or confined job sites.
Furthermore, Kubota manufactures the RA13974423 blade from high-strength steel to withstand repeated ground impact, abrasive soil conditions, rocks, gravel, and continuous heavy-duty use. Consequently, the blade maintains its structural integrity even under demanding construction and earthmoving applications. At the same time, the durable steel construction helps reduce wear and extend service life, allowing the machine to operate efficiently for longer periods.
Moreover, Kubota engineers this blade for direct OEM fitment, ensuring seamless integration into the factory blade system without the need for modification. Because of its precision-built design, the blade installs securely and aligns correctly within the assembly, which helps maintain consistent grading performance and operational reliability.
Whether you are replacing a damaged blade component or restoring full grading capability to your excavator, the KU-RA13974423 LH blade delivers the strength, precision, and reliability expected from genuine Kubota equipment parts. Ultimately, this OEM component helps maximize machine performance while supporting efficient excavation and landscaping operations in challenging working environments.
