Standard Features

Kubota V2607-DI Engine:
 The KX057-4 is powered by Kubota's impressive 47.6 hp direct injection engine. Engineered with the power to maximize digging and lifting performance, it also delivers minimized noise, vibration and fuel consumption.  
Auxiliary Circuit 1:
 Controlled by the right-hand joystick. AUX1 supplies 19.8 gpm to operate attachments requiring hydraulic flow, like a breaker, thumb, or tilt bucket.  
Adjustable Maximum Oil Flow Control:
 The maximum oil flow settings of both circuits are conveniently adjustable from the digital panel. No additional tools or complex manual adjusting procedures are necessary. You can even program up to five oil flow rates corresponding to specific attachments into memory on the digital panel.  
Stronger Bucket and Arm Breakout Force:
 The KX057-4 delivers an impressive bucket digging force of 11,177 pounds. Its powerful and well-balanced arm and bucket allow the operator to dig faster and more efficiently even in the toughest conditions.  
Wider, More Comfortable Cabin:
 The KX057-4 features a much wider door and ample foot space, making it a breeze to get on and off the excavator  
Two-Speed Travel:
 Placing the 2-speed travel switch on the dozer lever gives you more foot space, plus dozing operations can be done faster and easier.  
 Downshifting under load, the auto-shift system returns to high speed automatically, providing smoother turns and dozer work.  
Wider Working Range:
 A wide and powerful reach coupled with outstanding stability makes it possible to undertake a wider range of operations. The wide and powerful reach coupled with outstanding stability significantly reduces the need to shift position. The greater digging height means that operations - even from an elevated position - are handled with impressive efficiency.  
Three-Pump Load Sensing System:
 Kubota's improved three-pump load sensing hydraulic system ensures smoother operation, regardless of load size. It allows hydraulic oil to flow according to the specific range of the operator's lever motion. The result is greater fuel economy and smoother travelling.  
Five Lower Track Rollers:
 Travelling noise and vibration are reduced thanks to five lower track rollers. That helps reduce operator fatigue by the end of a long day.  
Powerful Air Conditioning:
 The overall air circulation in the cab has been improved, thanks to a stronger cooling / heating unit and the positioning of six vents around the operator to offer better all-round comfort.  
Thumb Bracket and Relief Valve as Standard:
 The hydraulic thumb makes short work of a variety of loading and material handling jobs. The factory installed mount brackets and hydraulics significantly reduce the time needed to mount accessories.
