Kubota Custom UG Extreme Machine 21kW
Kubota Custom UG Extreme Machine 21kW

The Custom made Kubota Model UGE-21 Series is a Super Quiet Series generator with 21 kW 60 Hz, of continuous output,  Tier 4 stand by and primary power tier 4 compliant. These industrial generators are suitable for prime power and standby use. When you require the dependability of an industrial grade generator the UGE Series is for you. Our custom built generators are available in several models from 8.5kW to 250kW available in single and three phase and priced competitively to deliver the performance and value found only on more expensive competitors models. Standard features include an upgraded powder coated weather sound attenuated enclosure, a 2 wire auto start module, a quieter residential muffler, a larger extended run time base tank, an on board circuit breaker, unit mounted solid state regulator, a 2 amp battery charger and a starting battery, battery rack and cables. 

United Generator’s Super Silent custom built Kubota and John Deere generators provide reliable power to meet the most demanding requirements. We use the same engines as the factory built models and the best Newage / Stamford alternators available. These generators are designed and built to withstand tough environments at construction sites, provide prime power for off the grid applications and dependable temporary clean power at entertainment venues and disaster recovery operations. By utilizing the latest state of the art voltage regulation and the highest quality solid state circuit boards our generators are safe to use with sensitive equipment like computers, cells phones and any where clean power is needed.  Our easy to maintain design offers quick access to all drain extensions and filters, which can be cross referenced at any auto store, making routine maintenance even easier.

We upgraded this unit to a quiet residential muffler, mounted it on a 100 gallon extended run time fuel tank, added an electric transfer fuel pump and included a free 2 wire auto start module. We upgraded the enclosure to a sound attenuated aluminum powder coated weather enclosure for longevity, rust resistance and super quiet operation. This unit includes every upgraded feature our customers repeatedly ask for making it turn key ready for a commercial or residential back up or an off the grid primary power source.

This model features a premium Kubota model V2403 engine, 36.1 HP, 4 cylinder, diesel fueled, liquid cooled engine with electric start. This model runs at 1800 RPM and generates 21 kW (20 kVA) 60 Hz of clean stable continuous power at a primary voltage of 120/240 VAC, single phase, 60 Hertz.

The price includes a factory warranty of 24 months
