The Omnia Rotary promise

A rotary with exceptional collection.

We built the Omnia Rotary around the five things grounds teams told us they want most from a rotary mower.

  1. Cylinder-like finish

    Three-tip blades take a shorter bite, for a cleaner, more even cut and presentation that stands up to close inspection.

  2. Collection you can count on

    A high-flow vacuum deck and a fully sealed chute keep clippings, leaves and debris moving into the grassbag.

  3. Height of cut you trust

    Independent left and right adjusters, a millimetre gauge on each side and a deck hung from a solid steel beam.

  4. Effortless handling

    Twin batteries balance the machine from side to side, and Smart Steering Assist comes as standard.

  5. Simple ownership

    No belts, direct-drive motors and familiar Omnia controls keep cleaning, setting up and servicing quick.

Raising the standard of rotary cutting.

The Omnia Rotary combines a staggered cutting deck with its innovative Tri-Cut blade design. Unlike conventional rotary blades with two cutting tips, each Tri-Cut blade features three, delivering 50% more cuts per revolution. This reduces the distance between cuts, producing a cleaner, finer and more consistent finish, closer to that of a cylinder mower.

Together, the staggered deck and Tri-Cut blades generate 30% more airflow, helping to lift grass and improve the collection of clippings, leaves and debris.

The three-tip design also allows blades to run at lower speeds while maintaining cutting frequency, reducing noise without compromising cut quality.

HIGH FLOW VACUUM DECK

Collect more. Leave less.

The Omnia Rotary features a high-flow cutting deck developed through research conducted by the University of Wolverhampton to optimise airflow and grass movement. The deck is designed to generate powerful suction, lifting grass for a cleaner, more consistent cut while efficiently collecting clippings, leaves and debris.

The deck's design helps maintain strong suction, directing cut grass smoothly through the collection chute and into the grassbag, reducing the risk of blockages and helping maintain consistent collection performance.

Following feedback from professional grounds teams, we've introduced an improved sealing system between the chute and grassbag to help prevent clippings from escaping, providing cleaner, more efficient collection in all conditions.

Height of cut

Greater control.
A more consistent cut.

Following feedback from grounds teams wanting a more secure and level height of cut, the Omnia Rotary features independent left and right height adjusters, giving operators greater control across a 15–50mm cutting range, with no tools required.

A rigid 40mm support beam provides strength and stability, helping maintain a level, consistent cut across the entire mowing width.

Try it yourself

Your speed. Your clip rate.

With independent motors powering the cutting blades and rear roller, the Omnia Rotary offers an infinitely variable clip rate, allowing operators to adjust cutting frequency and forward speed independently.

Increase the blade speed or reduce the forward speed for more cuts per metre, delivering a finer, more consistent finish.

Try it yourself! Adjust the sliders to see how blade speed and forward speed affect the clip rate and distance between each cut.

Twin batteries

Better balanced.
Easier mowing.

Following feedback from grounds teams that mowers with a single large battery can feel heavy on one side, the Omnia Rotary features two 1.8 kWh batteries positioned either side of the collection chute.

This creates a more even weight distribution, making the mower easier to steer, turn and manoeuvre, particularly during long mowing sessions.

With 3.6 kWh of total battery capacity, the Omnia Rotary is designed to mow up to two full sized football pitches on a single charge, with both batteries conveniently charged through one port.

SMART STEERING

Effortless turning.
Complete control.

The Omnia Rotary features Smart Steering Assist, designed to make turning and manoeuvring easier, even in tight spaces.

Two independent 1,000 W rear roller motors are controlled through the handlebar bale bars. When turning, one motor stops driving while the other continues, helping the mower turn smoothly with less effort from the operator.

This provides greater control, easier handling and reduced operator fatigue, particularly when making frequent turns during mowing.

Direct drive

No belts. Anywhere.

Featuring four independent direct-drive motors, with two 1,200 W motors powering the cutting blades and two 1,000 W motors driving the rear roller, delivering a combined 4.4 kW of motor power.

Unlike conventional systems, the Omnia Rotary operates without belts or chains. Its staggered blade design also eliminates the need for blade timing, reducing mechanical complexity and maintenance requirements.

With no belts to tension, slip or replace, there's less time spent on servicing and more time spent maintaining your turf.

Shaped by grounds staff

You told us. We listened.

During the Omnia demonstration season we asked football grounds staff what frustrates them about rotary mowers. The same answers came up again and again: the finish isn’t good enough, collection is inconsistent, height settings can’t be trusted, machines feel heavy and too much time goes on cleaning and adjusting.

The Omnia Rotary is our answer to each of them.

What they asked for

  • A rotary finish that rivals a cylinder mower

  • Consistent height of cut, with minimal scalping

  • Collection that copes with wet grass, leaves and debris

  • Even grassbag filling, without blockages

  • Neutral balance, easy turning and easy tip-back

  • Simple, intuitive controls and repeatable setup

  • Quick cleaning and easy servicing
