MacDon M155 Operators Manual - Manual (Page 133)

OPERATION
CAUTION
Operate both steering wheel and ground speed lever
slowly for familiarization. Remember that steering is
more sensitive when speed-range control is in road
speed position. Avoid the common tendency of new
Operators to over-steer.
8. If more tractive (lugging) power is required (for
example, when driving up a ramp, up a hill, or up out
of a ditch):
a. Move the GSL (E) closer to NEUTRAL.
b. Switch speed-range control (B) to L (low range).
9. Once the lugging condition no longer exists:
a. Set GSL (E) to NOT MORE THAN HALF maximum
forward speed.
b. Move speed-range control (B) to H (high-range).
Steering is more sensitive in this speed range.

Driving in Reverse in Engine-Forward Mode
WARNING
Back up slowly. Steering is opposite to normal when
reversing. Hold steering wheel at the bottom and turn
wheel in direction you want the rear (cab-forward) of
the machine to travel.
1. Move speed-range switch (A) to L.
2. Move throttle lever (B) to a mid-range position
NOTE: Reversing in low speed range and at
reduced engine speed is recommended
since steering will be less sensitive than
at higher speed settings.
