Added Power and Performance
Powered by a 28 hp* Vanguard® 810 EFI Engine with Oil Guard™, you will get a 500-hour oil change interval that can reduce maintenance time and costs by 60%**. (Select models)

Cool Oil for Efficient Use
External oil coolers for the dual Hydro-Gear ZT-3400 transaxles reduce oil temperature by as much as 25%, plus a new quick fill system makes maintenance that much easier.

Gas Tank Guard
Additional protection has been added to protect the gas tank from obstacles and debris.

Enhanced Foot Pedal Support
Upgraded with dual solid-steel return-to-neutral foot pedals for better user support.

New Spindle Access
We listened closely to our commercial users when considering the enhancements on our redesigned mower deck. The new, improved deck provides a new spindle easy-access slot for faster greasing and accessibility.

Ergonomic Parking Brake
We modified and added an angles parking brake that is pulled into the frame to prevent snagging or bending. This now provides instant access with minimal operator effort to each and engage.

Enhanced Muffler Guard
Enhanced muffler guard has been added to protect the O2 sensor on the EFI Oil Guard models.

Hydro-Gear® ZT-3400™ Transaxles
Dual commercial grade transaxles with remote oil coolers that reduce oil temperature by as much as 25% and feature 1.125" tapered axle, forged steel bull gear and steel cut pinion gear for enhanced performance in commercial applications.
