Do not perform shuttle shifting while using scarifier or while towing heavy load. Damage to
equipment may result.
Shuttle shifting, also known as directional shifting, allows operator to change machine direction quickly. Shuttle
shifting is performed by moving the transmission control switch from FORWARD to REVERSE position or from
REVERSE to FORWARD position WITHOUT stopping in the NEUTRAL position (Figure 13). If switch remains in
NEUTRAL position for more than 0.2 seconds, transmission will shift into NEUTRAL. The shifts shown in Table 1
are allowed.
