Electronic throttle control technology introduced to zero turns

June 3, 2020  By Briggs & Stratton

Briggs & Stratton Corporation’s Ferris brand has introduced two all-new models in the Ferris ISX3300 platform powered exclusively by the Vanguard BIG BLOCK 40.0 Gross HP* EFI ETC engine, the first in the lineup to feature Vanguard’s all-new electronic throttle control (ETC) technology. The ETC technology reacts instantaneously to any applied load from its environment to maintain power when the application demands. Equipping the premier zero-turn mower in the Ferris line – which also features an advanced independent suspension system, Forefront – with the most powerful engine in the Vanguard lineup creates the ultimate mowing solution.

“The all-new ISX3300 models – equipped with Vanguard’s most powerful engine yet – allow the mower to harness and put to work more of the power created by the engine,” Jennifer Walth, senior marketing manager – Ferris, said. “This allows the mower to make quick work of long, dense, wet grass for added productivity so our operators can go home feeling good at the end of a long day.”

The new ISX3300 models benefit from Vanguard’s all-new ETC technology. A flywheel speed sensor detects any change in speed and sends a signal to the throttle body, ensuring consistent engine speed and quality of cut, no matter the environment or load. Also equipped with EFI, this engine has improved starting at all temperatures, smooth performance at all elevations, quick load acceptance and reduced fuel consumption.

“We’re excited to offer Ferris customers another opportunity to benefit from Vanguard’s superior performance and durability by powering the ISX3300 with our most intuitive engine yet,” Chris Davison, senior marketing manager, Vanguard commercial power, Briggs & Stratton, said.


The Forefront Suspension System gives landscape professionals the ability to mow at a higher speed while having more control over the mower. This powersport-inspired front suspension geometry eliminates caster chatter, ensuring the front casters remain in the ideal orientation throughout the entire range of suspension travel to improve the ride and quality of cut. Forefront utilizes four solid control rods with hardened radial ends and dual-rate coil springs that resist component motion and allow the operator to select from five-position adjustments for conditions, preference and attachments. The Ferris Forefront system also features shocks with mower-specific internal valves, oil capacity and bump/rebound setting for maximum ground contact while absorbing terrain.

Available with either a 61- or 72-inch two-belt iCD cutting system, the ISX3300 is outfitted with Hydro-Gear ZT 5400 Powertrain transaxles and Hercules spindles.
