CLUTCH-BRAKE PEDAL
As you familiarize yourself with the tractor, you will
notice that when you depress the Clutch -Brake Pedal
approximately two-thirds, the clutch is disengaged.
This Clutch -Brake Pedal position also serves as a
br ake to s top th e v eh ic le wh en in gear . P ed a l ad -
justment is set at the factory and should not require
frequent attention unless the linkage has been dis -
turbed. Should clutch slippage become evident or
brake shoe lining is worn, see your Bolens dealer.
However, to prevent the vehicle from moving when
transmission is in NEUTRAL or when shifting into
another gear, particularly on inclines, it is neces-
sary to further depress the Clutch -Brake Pedal to
apply the Main Transmission Brake.
