Comparison & Correlation
• Kubota 15 vs. Kubota 17:
• The U15 excels in confined spaces (e.g., indoor demolition), while the 17 model adapts better to rugged terrain with its expandable tracks and stronger powertrain.
• The 17’s triple pump system offers superior efficiency during multi-action operations (e.g., bucket + swing).
• Nachi Pump & Kubota Excavators:
• The PVD-00B-15 can serve as a hydraulic system upgrade for Kubota 15/17 models, enhancing pressure stability and response speed.
• Verify interface dimensions and flow compatibility for seamless integration.
