Our patented suspension technology reduces the effects of uneven terrain,virtually eliminating shock to the chassis, and your body. Many operators are not always aware that they slow down to compensate for rough terrain. So when protected from these effects using a Ferris suspended ride-on-mower, the operator is able to take full advantage of the power available from the machine to maintain a consistent mowing speed. And by allowing you to maintain speed while mowing, it increases your productivity by getting the job done faster. The suspension system itself is designed to absorb the bumps and vibrations that can cause operator fatigue. This lets you power through each day, knowing that we’ll keep you feeling good for tomorrow.

So how does it work?

The Ferris integrated suspension systems are engineered with carefully selected components that work together to provide you with a smooth ride on uneven turf. The cutting deck of the mower works in conjunction with the suspension system to provide a consistent quality of cut. A reactive deck mounting system lets the mower deck float from the suspension and raises and lowers the deck in harmony with the motion of the wheels. These systems minimize shock to the chassis, and you, resulting in superior comfort, stability, traction and increased mowing efficiency.


Three front suspension systems

Forefront™ Suspension System

Forefront™ Suspension System
(ISX™ 3300, ISX™ 2200, ISX™ 800)

The turf industry’s most advanced independent suspension system utilizes two steel control arms for each front wheel that work with mower-specific coil-over shocks to ensure the caster wheel remains in an ideal vertical position throughout the full range of travel. This virtually eliminates caster chatter for a smooth ride and straight mowing lines – even when mowing at full speed.

IS® Single-Arm Suspension System

IS® Single-Arm Suspension System
(IS® 6200, IS® 5100Z, IS® 3200ZIS® 2600IS® 2100Z)

Proven independent suspension technology utilizes a single indendent control arm for each front wheel and coil-over shocks to minimize caster chatter as the front casters follow a slight arc through the full range of travel. This dampens the shock load that is caused by rough terrain - allowing mowing at higher rates of speed.

Pivoting Front-Axle

Pivoting Front-Axle
(400S, IS® 600)

A pivoting front axle combined with coil-over shocks allows the front wheels to adjust to uneven terrain. The coil-over-shocks dampen the front-axle movement and allow the wheels to remain in better contact with the ground, enhancing stability.

Rear suspension system

Rear suspension system

All suspension models

The swingarm rear suspension system utilizes coil-over shocks and a shared pivot point for the rear wheels. This allows the rear wheels to move in unison with one another, enhancing stability and smoothing out the ride over uneven terrain.
