🚜 Powerful Upgrade: Hitachi EX330.3 Fitted with United Seats Highlander Pro

April 12 2025, by Maris Stekels, 3 min reading time

United Seats, together with their official Spanish distributor Sumsertech, has recently completed the installation of a Highlander Pro seat into a Hitachi EX330.3 crawler excavator — a perfect example of how premium seating can significantly enhance machine performance and operator comfort.

This installation was completed in close cooperation with the United Seats team and is part of an ongoing commitment to supply high-quality seating solutions for demanding construction and heavy machinery applications.

🛠 Installation Details

The Highlander Pro was installed directly onto the OEM seat plinth, located between the joystick pods, replacing the factory-fitted seat. The plug-and-play design of the Highlander Pro made the integration seamless, requiring no major modifications to the base.

For operators spending long hours on rough terrain, seat suspension and body support are critical. The Highlander Pro’s horizontal suspension system helps absorb the constant forward and backward jolts common in excavation work. This reduces fatigue, minimizes back strain, and contributes to safer, more productive operations.

💡 Why Choose the Highlander Pro?

The Highlander Pro is one of the top choices in the United Seats construction line-up, offering a wide range of ergonomic and functional benefits:

✅ Fore/aft horizontal suspension to dampen jolts from machine movement
✅ Adjustable vertical damper for tailored ride comfort
✅ Robust mechanical suspension rated for tough environments
✅ Comfort contour seat cushions for long working days
✅ Modular components for easy replacement and servicing
✅ Available in multiple upholstery and configuration options

The Highlander Pro’s ergonomic profile makes it ideal for medium to large excavators, wheel loaders, and industrial machines where operator endurance and comfort are key.

“Once again, a fantastic installation delivered by our trusted Spanish partner Sumsertech. We are proud to work alongside a strong European dealer network to deliver premium seating experiences across all applications.”
