Multi-Patented Suspension Technology
This innovation reduces the effects of uneven terrain, virtually eliminating shock to the chassis and your body.
Cover more ground in less time, without handing the rough patches to your operators or your machines. Ferris zero turn mowers combine patented suspension with durable commercial decks, so you can hold a steadier speed over uneven ground, work tight lines around obstacles and get through the day with less fatigue at the end of the day. Available in petrol and diesel, with cutting widths from 112 cm to 183 cm, every current model is backed by a 10-year limited suspension warranty.*
The Ferris petrol range runs from compact machines built for narrow gates and obstacle-heavy sites to high-output platforms for large open ground, so you can match cutting width, suspension platform and drive system to the jobs you actually take rather than compromising on a single do-it-all machine.

When the job calls for maximum torque and all-day runtime, these two machines deliver Stage V power, patented suspension and commercial-grade cutting systems built to keep going. Both are approved for HVO100 renewable diesel, so you get a lower-carbon fuel option without changing a single component on the mower.
A suspended seat only isolates your spine, your hands and arms still take every jolt through the controls, and the chassis, deck and drivetrain absorb it with nothing to soften the blow. Ferris suspension works at mower level, reducing the shock that reaches you and the wear it puts on the machine.
That matters for more than comfort, it affects your speed too. Most operators back off instinctively when the ground gets rough, because neither they nor the mower can absorb what the terrain's throwing at them without slowing down. Reduce that shock and you can hold a steadier higher speed for longer, getting more from the power you're already paying for.
Not every model rides the same. The 500S and IS® 600 use a pivoting front axle, while the IS® 6200 tops the range with fully independent suspension front and rear. All that, and everything in between is covered in detail on our suspension technology page.
On applicable models, it's not just the frame that moves independently: reactive deck mounting lets the cutting deck follow the suspension and wheel travel too, so it tracks the ground consistently without scalping.
And it's all backed for the long haul, every current Ferris zero turn mower, petrol or diesel, carries a 10-year limited suspension warranty. *
There's a lot of forum chatter about full suspension causing scalping, adding complexity or being harder to maintain on slopes. Most of it doesn't hold up. Read Mower Myths Busted for a straight answer to the most common concerns, or see how Ferris suspension compares to a suspended seat to understand exactly what the difference means for your chassis, your deck and your working day.
Independent left- and right-hand drive levers let you vary the speed and direction of each wheel, so the mower pivots within its own footprint. That means fewer three-point turns, tighter passes around trees and beds, and less time spent reversing out of corners a conventional ride-on can't reach cleanly.

Selected Ferris models use Triple™ or Triple iCD™ deck technology giving you rear discharge, side discharge and mulching from a single deck. Rear discharge keeps clippings clear of paths, beds and passers-by. Side discharge clears volume fast when there's room to work with. Mulching returns finely processed clippings to the turf when growth and mowing frequency allow it.
Ferris doesn't fit one engine to every machine. Compact petrol models run Briggs & Stratton® CXi engines; higher-output petrol platforms step up to Vanguard® EFI power with Oil Guard™ for extended service intervals, whilst the diesel range uses Stage V Yanmar and CAT® engines. Hydro-Gear® drive systems are sized to match. That means you can pick the cutting width, suspension platform, engine and fuel type that fit your workload.
The widest deck isn't automatically the fastest choice, it’s only fast if it can actually get onto the site and move freely once it’s there. Work through access, cutting width, discharge, fuel, and transport in that order, and the right model tends to become obvious.
Measure before you choose. Check the narrowest gate, path, trailer ramp or storage opening the mower has to pass through, and use the complete machine width rather than the nominal deck width, particularly where a side-discharge deflector adds to the footprint. Also think about how much room you need to turn, load and service the machine on site.
Match cutting width to the ground:
Decide on discharge. Rear discharge keeps clippings contained, which helps around paths, beds, vehicles and public areas. Side discharge clears volume quickly where there's space to manage it. Mulching finely processes clippings and returns them to the turf, provided growth rate and mowing frequency suit it. A Triple™ deck lets you switch configuration as the site or the season changes, rather than locking you into one setup.
Match fuel to the work. Petrol gives you the broadest choice of sizes and cutting widths, from the compact IS® 600 through to the 183 cm ISX™ 3300. Diesel suits long, demanding shifts and fleets already built around diesel servicing, with the added option of running on HVO100 renewable diesel without modifying the mower. Your decision should weigh daily hours, existing fuel arrangements, servicing support, transport and the type of contracts you take on.
A specification sheet can't tell you how a mower feels crossing the terrain. A demonstration lets you judge suspension response, visibility, control and cutting width under conditions that actually match your working day.
For contractors and grounds teams who demand consistent daily output, battery-electric equipment isn't the only way to go green. HVO100 drop-in renewable diesel offers a seamless alternative.
It fits right into your existing operations and even mixes with standard fossil diesel. You can slash emissions today without retiring productive equipment early or dealing with charging downtime. Both the IS® 2600 and IS® 6200 are approved for HVO100 with zero modifications required, allowing you to achieve up to a 90%** well-to-wheel CO₂ reduction.
