- Kubota (UK) Ltd’s five-model M6-001 Utility series tractor range made its Royal Highland Show debut last week, on stand S-264. As the successor to the MGX range, the M6-001 Utility models span 104-143hp, and meet EU Stage V emissions thanks to an improved exhaust after-treatment package that contributes to lowering the cost of ownership
Short wheelbase models include the M6-101U and M6-111U. Both use a 3.8-litre Kubota V3800 four cylinder engine, producing maximum power of 104hp and 111hp respectively, with maximum torque figures of 346Nm and 379Nm. These models weigh 4.3t and have a 2.54m wheelbase.
M6-121U, M6-131U and M6-141U sit on a 2.68m wheelbase, and use Kubota’s 6.1-litre V6108 four cylinder engine. Power outputs are 123hp, 133hp and 143hp, with maximum torque figures of 503Nm, 544Nm and 586Nm respectively. These three models weigh 4.8t.
Engine technology on all models has seen an improvement in exhaust after-treatment, with DOC and DPF performance increased to deliver greater operational flexibility and lower cost of ownership. DPF regeneration can now be achieved at a much lower engine speed – typically 1,200rpm down from 2,000rpm – and using a much lower working temperature of just 50 degrees C. The latter makes regeneration much easier to achieve with light engine loads, lower noise levels and a reduced fuel burn.
DPF cleaning intervals are 8,000 hours for the 6.1 litre engine, and up to 6,000 hours for the smaller 3.8 litre engine, again contributing to reduced operating costs. The engine oil change requirement is every 500 hours, on all M6-001 Utility models.
Across the series, a 40kph semi-powershift transmission is used, which provides eight powershifts in three mechanical ranges to create a 24×24 gearbox. The option of a creeper range increases the choice of ratios to 32×32. Transmission functionality includes auto-shifting in each range, and a sensitivity dial – the latter allows operators to adjust the responsiveness of gear changes to suit load on the tractor.
Operator comfort is provided by an air suspension seat in the same cab frame shared wth M6-002 and M7-003 models, while front axle suspension is available as an option. A wide sunroof offers generous visibility for those looking to equip M6-001 Utility models with a loader, of which there are two variants – 3.7m or 4m lift height to the pin, and maximum lift capacities of 1.95t or 2.2t respectively.
A fixed displacement open centre hydraulic system provides 71 and 77 litres/min of oil flow respectively for short- and long-wheelbase models, while two mechanically operated spool valves are fitted as standard. Two additional spools are optional.
Cat III rear linkage includes electronic linkage control with a 5t lift capacity on short wheelbase models and 6.1t for long wheelbase tractors. PTO equipment includes 540/1000 speeds as standard, with a 540 Eco option available. All models can be equipped with an optional front linkage with 2.6t lift capacity, and the ability to run pto-powered equipment while stationary.
M6-001 Utility models also benefit from Kubota’s portal front axle with bevel gear drive, offering generous ground clearance and a 55-degree steering angle.
Prices start from £56,757 for the 104hp M6-101U, and from £80,365 for the M6-141U. A range of Kubota Care warranty packages are available, with up to five years and 5,000 hours of cover.
