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.  
AUX1 Diverter Valve
 With the AUX1 diverter valve the AUX oil supply can be changed without having to remove the thumb pipeline when the operator wants to use a hydraulic attachment.  
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.  
Deluxe Suspension Seat
 Kubota's high-back suspension seat has been designed for maximum operator comfort and to minimize fatigue during extended machine operation. The deluxe reclining seat offers weight compensation, firm adjustable wrist support and retractable seat belts.  
ROPS / OPG (Top Guard, Level I) Canopy and Cabin
 The OSHA-certified ROPS / OPG (Top Guard, level I) canopy and cabin provide protection in the event of accidental rollovers and falling objects.
