Top of the range is the 8m Tri-Deck, offering wide area mowing with cost-efficiency. Each deck on the triple mower has full width rollers at the front and rear that restrict airflow. The high speed blades create suction beneath the deck chamber and the uncut grass is sucked up by the blades, leaving a high quality cut at high speeds.

The system works effectively across the whole range. Operation is simple and there are no electro-hydraulics or electric clutches. The transmission system allows wings to be engaged and disengaged whilst in work and wing control is independent. The folding wings can cut gradients from -30° to +30° with the middle deck remaining on level ground.

While the 8m Tri-Deck roller mower is built for very large areas there is also the RMX-680 at 6.8m width, the RMX-560 at 5.6m and the newly introduced 5m width RMX-500.  

The RMX-360 is a 3.6m folding wing mower which can be safely transported on the roads, spanning 2.4m with the wings folded. At just over 3.1m overall width the Wessex ProLine RMX-300 is the largest rigid deck mower in the range. It has a minimum power requirement of just 55hp. Running five precision spindles beneath the durable deck, the RMX-300 has a cutting width of 3m. Smaller models of the rigid decks are available in 2.4 and 1.8m working widths.
