BOLT (KU-7072434374)
Description:
The Kubota 7072434374 Bolt delivers secure and dependable fastening by firmly clamping mower blades to the spindle assembly during operation. Engineered to Kubota’s OEM standards, this bolt maintains consistent torque retention, thereby ensuring correct blade alignment and stable high-speed rotation.
Moreover, Kubota manufactures this bolt using heat-treated, high-tensile steel, which allows it to withstand extreme centrifugal forces, vibration, and impact from debris. As a result, it resists loosening and fatigue over time, even in demanding mowing conditions.
In addition, the precision-machined threads ensure a tight, accurate fit within the spindle shaft, which improves load distribution and reduces the risk of thread wear or stripping. At the same time, it works in conjunction with the cutter retainer and blade, creating a balanced and secure mounting system that minimises vibration and enhances cutting performance.
Furthermore, the bolt’s OEM design enables quick installation and direct replacement without modification, making maintenance more efficient. Consequently, it plays a vital role in ensuring safe blade retention, protecting deck components, and maintaining consistent cutting quality.
Ultimately, the KU-7072434374 bolt provides a robust and reliable fastening solution, making it an essential component for maintaining the safety and performance of Kubota mower decks.
