On Delay Timer
(#2, #3 mower unit up/down switch timer)
The on delay timer is located under the right
side of the seat, and is connected to output an
up/down signal to the rear mower unit after
the up/down signal to the front mower unit.
This design makes the rear mower unit move
up/down with a 0.6 second delay after the up/
down signal for the front mower unit.
