Bison Mechanical Park Brake: Unparalleled Clamp Force & Performance

Larger deck sizes. More powerful engines. Heavier weights and faster speeds. Today’s zero-turn mowers (ZTRs) are bigger and better than they were just a few years ago – so big, in fact, that keeping them securely in place can be a challenge, especially when placed on a trailer or sitting on an incline. 

That’s exactly what inspired Hayes to develop a mechanical parking brake that guarantees stationary placement in a single force. Aptly named Bison, this brake is an industry first, with calipers that can create 2,500 pounds of clamp force. Like the animal, these brakes have stamina and stopping power that make them unrivaled in the turf vehicle industry.

The engineers at Hayes didn’t compromise when it came to durability, either. Made of steel with components plated in either nickel or zinc, this brake has been subjected to an aggressive 96-hour salt spray protection test – and passed with flying colors. Bison performs, no matter the challenges of the elements or terrain.

While initially developed for lawn and turf ZTRs, Bison can provide reliable clamp force for other vehicle types, too. The Bison system offers a floating mount and multi-lever offset to fit everything from turf and UTVs to golf carts and EVs (electric vehicles). 

Its incredible clamp capability and proven durability make Bison an exciting opportunity for lawn and turf vehicle OEMs, and for OEMs of off-road vehicles, to make their equipment more attractive to buyers. Safety is among their key purchase considerations, and with Bison holding the vehicle in place, there’s no chance of rolling away (and potentially causing damage or injury).

Dealers with used inventory can make their vehicles more attractive, too. Upgrading older mechanical parking brakes to Bison will improve the equipment’s stopping power, giving buyers added confidence in the safety and performance of the vehicle. Not only that, but they recognize that new and stronger brakes have more useful life and require less maintenance, too.
