Multi-patented Suspension Technology

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. 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.

Keep Your Staff On Board

Operator comfort is a measurable productivity metric. Want to know more about how our suspension helps you retain your best workers and stay compliant with EU vibration directives?

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.

Proof that it's built to last

Ferris owners prize their mowers for the full suspension that delivers a best-in-class ride. Now, we are covering that suspension with a 10-year warranty. It is just one more way we are standing behind our technology.

The new 10-year suspension warranty doubles the previous 5-year warranty and applies to any new Ferris ride-on mower purchased after 1 November 2025. It is in addition to the 4-year/500-hour warranty on most of our ride-on and stand-on mowers.*

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^® 2600, IS^® 6200)

Proven independent suspension technology utilizes a single independent 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
(500S, 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

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.

By keeping the mower chassis level, this system maintains optimal front caster 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.

Commercial mower specialist

In an industry where productivity against investment is becoming even more important, the direct link between operator comfort and ground coverage is definitely food for thought when purchasing new equipment. Ferris IS^® or ISX™ suspension results in reduced shocks to the chassis, superior operator comfort, increased mowing speeds, better stability and an extended overall mower life. That’s why Ferris is the commercial mower specialist for your business!

Mythbusters: Setting the Record Straight on Full Suspension

If you have been researching full suspension mowers online, you have likely come across a lot of myths and conflicting opinions. Because of these common misconceptions, people often rely on a standard suspended seat to get them through rough or uneven terrain instead of looking at full suspension.

The reality is that a suspended seat is only a half-measure. It protects the operator's back, but leaves the mower to absorb every harsh impact. Ferris IS® or ISX™ independent suspension changes the approach by isolating the entire machine. This not only keeps your crew comfortable but also safeguards your mechanical components and allows for faster mowing speeds.

Let's take a look at the facts and put the seven most common misunderstandings to rest. BUST THE MYTHS: Read our full breakdown of the facts behind full suspension here.
