8. What Max Turn Rate and Steering Speed should I set for my track
tractor?
Follow the recommended settings provided in the hydraulic
installation manual for your specific vehicle. Use the Steering
Speed value to adjust how fast the vehicle reacts to steering
commands. Only use the Max Turn Rate to prevent the tractor from
making large overshooting steering corrections when acquiring the
line or reacting to disturbances. Adjust the values by 5 points at a
time to get close to the desired performance then begin adjusting
by finer increments to optimize the system.
9. Should the vehicle steering wheel turn when eDriveTC is
operating?
No, under normal field operation the vehicle steering wheel should
not turn when eDriveTC is steering. When performing the steering
adjust function the steering wheel may begin to turn if eDriveTC
after the steering cylinders have reached the end of their stroke. If
the vehicle steering wheel is turning as the machine is auto-
steering through the field then you need to make sure that you
have a counterbalance valve properly installed.
10. Will the eDriveTC engage in reverse?
Yes, but the steering commands will be in the opposite direction
and the machine will not steer correctly onto the line.
11. I opened the hydraulic flow control all of the way and the steering
cycle time does not decrease.
There could be too much resistance on the steering wheels for the
eDriveTC to completely steer left and right. Perform the steering
adjust function with the vehicle rolling slowly to check the cycle
time.
