Stop engine, wait for all moving parts to stop, and remove key or pull out spark plug lead.
The drive control is a system of interconnected machine elements made up of steering and braking functions, that is
to say, one steering lever applies to neutral latch lock position or neutral latch unlock position. When two steering
levers are in neutral lock position, the power is disengaged. To brake, adjust brake lever and control rod beside the
mower of the same strength.
Adjusting control rod: Remove hair pin on the top of control rod, pull out the control rod from steering lever, turn the
control rod so that the length of two control rods is the same and reinstall all parts in proper order. (See FIG 12)
Adjusting the brake force: Lift the left / right shift rod and lock it by the buckle. Rotate nut 1 and nut 2 of the brake lever,
so as to compress the spring to get enough brake force. Then rotate nut 1 again, ensure that 1mm gap is maintained
between nut 1 and the rod end connector.
