Folding Rollover Protection System (ROPS)

A Rollover Protection System (ROPS), complete with seat belt, comes standard for operator protection in the case of accidental rollovers and tipovers. In situations where sufficient vertical clearance is not available, such as loading on an enclosed trailer, the ROPS can be temporarily unlocked and folded down.

High-performance Discharge Chute

High performance 8 mm rubber discharge chute allows for close trimming without damaging chute or landscape structures. Patented design provides excptional clipping dispersion.

Patented Adjustable Baffle

Allows operator to achieve maximum cutting performance by fine-tuning deck to conquer changing conditions, unique job sites or different times of the season. In extreme conditions, the baffle can be opened in order to conserve power and achieve faster mowing speeds. In less demanding conditions, the baffle can be closed to yield micro-sized particles and maximise discharge velocity.

Smarter design in a bull-nose bumper.

7-gauge bull-nose bumper not only protects against frontal impacts, but also contains an integral underskirt to minimise blowout of debris and dust. The bottom, leading edge of the deck is raised 6.35 mm, allowing grass to stand more upright when entering the cutting chamber, ensuring a level cut. Leaf “ploughing” during spring and fall clean-up also is significantly reduced.

A Flat Crisp Cut with Precision Blades

6.35 mm thick precision blades resist flexing to provide a flat, crisp cut. High-strength, heat-treated alloy steel survives impacts and provides resistance to the rapid wear commonly associated with abrasive conditions. Options include Recycler® and Atomic® mulching blades, medium sail Bahai blades, and low sail sand blades.
