Title:
SPRING,PLATE (KU-RD45119140)
Description:
The SPRING,PLATE (KU-RD45119140) provides controlled tension within Kubota assemblies, while also helping maintain consistent pressure between components. As it flexes under load, it absorbs movement and returns to its original shape; therefore, it stabilises connected parts and prevents unwanted play or vibration.
Moreover, Kubota manufactures this plate spring from high-quality spring steel, so it resists fatigue, deformation, and wear over repeated cycles. In addition, its flat, compact design allows it to fit into tight mechanical assemblies, which ensures efficient operation without adding bulk. As a result, it improves component alignment, enhances durability, and supports smooth mechanical function.
Model Fitment:
The KU-RD45119140 plate spring is primarily used in Kubota groundcare and mower deck assemblies, where controlled tension and alignment are critical. Because it is an implement and deck-specific component, Kubota assigns it based on deck configuration and linkage design, rather than a single machine model.
Primary OEM Fitment – Kubota Mower Deck Systems
This plate spring is most commonly installed in Kubota rotary cutting decks and mower linkage systems, particularly in mid-mount and rear discharge configurations.
Compatible Deck Series
- RCK Series (Mid-Mount Mower Decks)
- RC Series (Rear Discharge / Finishing Mowers)
These decks use plate springs in:
- Blade engagement linkages
- Belt tensioning systems
- Deck lift and stabilisation mechanisms
Tractor Compatibility (When Equipped with Above Decks)
Because the spring is tied to the deck, it applies to tractors only when fitted with compatible mower decks.
Compact Tractors
- B Series (e.g. B2301, B2601, B3150)
- BX Series (e.g. BX23, BX25D, BX2380)
These tractors commonly use RCK mid-mount decks, and therefore may include this spring within the deck assembly.
Zero-Turn & Groundcare Equipment
- Kubota zero-turn mowers (selected models)
- Commercial mowing units using similar deck systems
In these machines, the spring supports:
- Deck linkage stability
- Blade engagement consistency
