Three 141-horsepower wheel loaders have been upgraded to Dash 6 by Hitachi Machinery Loaders America (HCMA): ZW140-6, ZW150-6, and a parallel lift model ZW150PL-6. Operating weights are 25,640 pounds for the ZW140-6 and 26,960 pounds for the ZW150-6. Standard buckets are 2.7 and 3.1 cubic yards, respectively.
Three types of lift arms are available: standard, high lift, and parallel lift.
The parallel/tandem hydraulic circuit smooths out digging operations while the tandem function prioritizes the bucket while dumping. An automatic return-to-dig function resets the bucket for the next load.

The Dash-6 hydrostatic transmission offers two auto modes and one manual mode. A shift-to-hold switch overrides automatic settings to hold the wheel loader transmission in its current gear until the operator presses it again or changes direction. This gives it the extra traction or torque required at that time. A 1st range maximum speed selector offers settings from 4 to 8 mph, allowing the operator to apply higher rpm at low speeds for maximum hydraulic output for hydraulically driven attachments, according to the company.
The Approach Speed Control automatically detects the needs of the operator by increasing the front arm speed and maintaining driving speed, allowing improved productivity during short operation cycles without relying on the inching pedal.
The Traction Control System (TCS) reduces tire slippage and Increases tire life. Again, the technology serves to boost productivity under any wet or muddy ground conditions and is especially useful in snow plowing and removal applications.
The ZW140-6 and ZW150-6 models are also equipped with a Power Mode switch, delivering an instant 10-percent burst in engine rpm. Available in any auto and manual ranges, Power Mode provides immediate access to faster acceleration, more rim-pull, and higher breakout force without limiting the loader’s top speed. Power Mode also enhances hydraulic flow to increase front arm speed by up to 10 percent for faster lift cycles.
The Dash-6 cab operator’s compartment is pressurized and has a virtually airtight seal to keep out dust and dirt. The fully adjustable tilt/telescoping steering pedestal is linked to a pop-up pedal that quickly returns the steering pedestal to its start position.
A seamless front window, rounded engine cowling, and redesigned ROPS frames allows clean 360 degrees line of sight. The exhaust and intake stacks are relocated to the far rear of the engine cover and mounted inline to minimize their profile in the operator’s view. The rear pillars of the ROPS frame struts are mounted forward and away from the rounded corners of the cab. A rear-mounted safety camera is standard equipment, along with a proximity detection system providing audible and visual alerts for stationary and moving objects up to 20 feet from the loader.
Under the hood, Hitachi offers popular smart features such as ride control, telematics, and auto power-up. Hitachi’s ConSite reporting program gives fleet managers 24/7 remote monitoring, maintenance and daily operational data plus monthly summary reports. Up front, the multifunctional LED color monitor provides day and night readability for all machine conditions and settings.
