Your Grove carrier is equipped with a Roadranger RTO 613 transmission which provides 13 speeds
forward and 3 speeds in reverse. As the carrier is normally used as a highly mobile crane that might be used for
both ON and OFF highway application, no hard and fast rules can be given for all gear shifting sequences.
A "rule of thumb" definition of highway "shift points" or "shift speeds", are those speeds attained at
governed engine speed in each ratio. It is important that these speeds be learned in order to avoid clashing gears
while shifting and to take advantage of the proper ratios for existing road and terrain conditions.
