    • The AutoQuad™ PLUS transmission features all the benefits of a PowrQuad PLUS, with the ability to automatically shift four power shift gears depending on engine rotations per minute (rpm) and load. For specialty uses like vegetables, orchards, and other operations that need extremely slow speeds, creeper speeds are available with the AutoQuad PLUS transmission with a minimum ground speed of 0.27 km/h (0.17 mph). The 6155MH offers AutoQuad PLUS transmissions in a standard and creeper configuration featuring 20F/20R 30K.
    • The CommandQuad™ PLUS maintains the impressive reliability of an AutoQuad transmission while enhancing operator convenience and productivity through increased automatic shifting capabilities. The transmission is equipped with 20F/20R speeds, a left-hand reverser, and four PowerShift gears in five fully synchronized ranges (six-range transmission for the less powerful models). The selected powershift is displayed on the digital display (1 to 4). It features an AutoClutch and two operating modes – AUTO mode and manual mode:  
      • Manual mode: the operator can shift through speeds and ranges without clutching by moving the control lever forward, toward the + indicator, or backward, toward the - indicator.
      • AUTO mode: the tractor shifts automatically at present shift point depending on engine load
  • Higher ground clearance with the rear drop axle on the 6155MH Tractor

    Exclusive to the 6155MH Tractor, the optional rear drop axle provides additional crop clearance under the axle as well as additional drawbar clearance compared to a standard base axle with high clearance tires.

    If you are looking for a low-cost integrated guidance system, 6M Tractors come equipped with AutoTrac guidance using the digital cornerpost display. For this straight track only feature, you no longer need an additional display or activation. To utilize AutoTrac on the cornerpost display, simply order your 6M Tractor as AutoTrac Ready (code 1758) and install a StarFire™ 6000 Receiver (code 1881). While AutoTrac makes straight passes, you can focus more on job quality and leave the field less fatigued after a long day of mowing, spraying, or other field work.


    Benefits of AutoTrac on the cornerpost display include:

    • Easy to access, setup, and initiate
    • Eliminate implement overlap and optimize machine efficiency
    • Reduce operator fatigue
    • Less cost than adding an additional display and activation


    If you need more capabilities, like different track types or documentation, John Deere also offers a 4240 and 4640 Universal Display. These displays enable AutoTrac guidance that provides enhanced usability, increased performance, and greater operator choice. Additional benefits include:

    • On-screen mapping
    • Documentation
