Exmark Advantage: Hydro Drive System

March 23, 2016

Exmark Pioneer S-Series zero-turn mower

Exmark hydro drive systems deliver increased reliability, durability and ease of use for landscape professionals and homeowners alike.

The heart of any zero-turn mower is the hydro drive system. It’s the system responsible for controllably putting the power to the ground — undoubtedly an important job.

That’s why Exmark has worked hard to develop innovations that make its hydro drive systems function better, more reliably, with increased long-term durability. Working in partnership with Parker, we designed a unitized pump and motor unit that eliminates all hoses, fittings and potential leak points.

In testing, the Exmark UHT drive system in combination with Exmark Premium Hydraulic Oil has been proven to operate in the toughest commercial conditions while maintaining cooler system temperatures than the “off the shelf” hydro drive systems used by other manufacturers.

Exmark UHT hydro drive system

The UHT hydro drive system on Lazer Z zero-turn riders is designed to work harder, stay cooler and last longer than other hydro drive systems.

With no hoses and fewer parts to wear out, Exmark drive systems are more durable and easier to maintain than traditional drive systems. In fact, with proper preventative maintenance and care, the UHT hydro drive system on an Exmark Lazer Z can deliver 3,000 hours or more of productive mowing. That’s durability you can count on for years to-come!
