For those managing large areas where performance matters every day, the Kubota G231 Ride-On Mower offers a dependable and capable solution. Designed for professional users for whom only the best will do, it combines diesel strength with refined handling and impressive output. The result is a machine that works hard, delivers a first-class finish, and is a pleasure to operate from start to finish.
Perfect for estates, sports grounds, and commercial sites, the G231 Kubota mower is expertly engineered to exceed expectations where efficiency and cut quality are essential.
Engine Performance That Keeps You Moving
Powering the Kubota G 231 riding mower is a robust Kubota D902 diesel engine. This three-cylinder, water-cooled unit produces 22hp (16kW) from an 898cc capacity. It delivers steady torque to help the mower tackle thick grass and uneven ground without hesitation.
Speed is another standout feature. With a top forward speed of 11.8mph (19 km/h), this ride on mower ranks amongst the quickest machines in its category. Reverse speed reaches 3.8mph (6 km/h), making repositioning smooth and efficient. A 20-litre fuel tank supports longer sessions, reducing interruptions and keeping your workflow consistent.
Smooth Drive and Confident Handling
The hydrostatic transmission has been developed to handle demanding workloads with ease. Operation is simple, with a single pedal controlling both speed and forwards/ reverse direction. This intuitive setup makes it easy to focus on your mowing rather than the controls.
Enhanced braking response is achieved through an improved throttle valve. This gives you better control when descending slopes or navigating tighter spaces. The Kubota G231 mower feels stable and responsive at all times, helping you maintain cutting accuracy across varied terrain.
Precision Cutting Across All Conditions
Delivering a professional finish requires a machine that’s consistent, and here the G231’s cutting system excels. The 48-inch (122cm) deck allows you to cover more ground quickly, improving efficiency on larger lawns.
Twin blades ensure a clean cut in both light and dense grass. The electromagnetic PTO clutch transfers power efficiently, reducing strain on the system. Engaging the blades is straightforward, using a simple switch.
You can adjust the cutting height between 25mm and 102mm, providing the flexibility required for different surfaces and times of year. The deck is designed to minimise blockages, thanks to its enlarged chute capacity. Integrated cleaning levers make it easy to clear any build-up and keep performance at its best.
Fast and Flexible Grass Collection
You can choose between Kubota G231 HD (high dump) and LD (low dump) models, offering versatile collection options to suit different working environments. The high dump variant features a 640-litre capacity, while the low dump version offers 560 litres.
With the high dump system, you can empty the collector at heights of up to 1,970mm. This is ideal for loading directly into trailers or containers. The entire process takes less than 15 seconds, making it the most efficient system in its class.
Kubota’s Kross Control joystick allows you to manage both the deck and collector from one place. Lifting, lowering, and emptying the collector becomes simple and efficient. Built from high-density steel, it is made to endure challenging conditions.
Designed Around Operator Comfort
Long hours demand a ride on mower that is comfortable to use. The Kubota G231 is designed with this in mind, offering a quieter working environment thanks to its integrated resonator.
The steering wheel can be adjusted to suit your preferred position, while power steering keeps handling light and responsive. Cruise control is included to help you maintain a steady pace over large areas of land.
The clear instrument panel displays all the key information at a glance. With everything easily visible, you can focus on your work without distraction.
Safety and Monitoring as Standard
Working safely is essential, especially when you’re operating powerful machinery. The Kubota G 231 is equipped with a ROPS (roll-over protection system) for added peace of mind when operating on inclines or uneven ground.
An engine stop lever allows for immediate shutdown, if required. This Kubota mower also includes a water temperature gauge, overheating alert, fuel gauge, and hour meter.
Combined, these features help you monitor performance and stay ahead of maintenance needs.

Keeping the Kubota G231 tractor mower in top condition is straightforward. The one-piece bonnet opens fully, providing easy access to the key service areas. Routine checks can be carried out quickly, helping to reduce downtime.

FAQs
What is the difference between a low dump and high dump collector?
A low dump collector empties closer to ground level, making it useful for tipping grass onto open areas or low trailers. A high dump system allows unloading at height, which is ideal for skips or larger containers.
Can the Kubota G231 handle leaf collection?
Yes, it performs very well at this type of work. The strong airflow and large collector make it highly effective for gathering leaves and other organic debris.
How should the collection system be cleaned safely?
Use the built-in chute levers to clear debris and then ensure the collector is empty. Always turn off the engine and remove the key before carrying out further inspections.
What checks should be completed before using the mower?
Before starting work, check fuel, oil, and coolant levels. Inspect the blades, tyres, and safety features to confirm everything is operating correctly.
