④
Down speed control knob (Roll-bar
type)
 It is use to adjust the down speed of the 3-point
linkage. Turn the down-speed control knob to
the right direction for slower down speed, and to
the left direction for faster down speed.
 If turning the knob right direction fully, the
implement will be fixed and even if lowering
down the position control lever, the implement
does not let down.
- Tiller: Slow in down speed
- Plough: Fast in down speed
 When working in hard ground, slow down the
down speed to avoid bounding of the implement.
▶ When driving on the road, replacing tiller blades or removing grass around the tiller
blades, turn the down-speed control knob clockwise slightly to lock.
▶ The knob rotates about two revolutions. Do not over-tighten the knob. It may cause
damage to the control valve and connection parts.
