We've never thought a foot control would be just right. We have considered
it. The main thing is when you plow, you almost always are backing up as
you raise the plow. So with the timer or some other sort of automation, all
you have to do is bump the toggle then backup. We find people tend to hold
the switch in the up position for the duration of the reverse movement just
due to lack of thinking right. . After you've been doing it for 24-36
hours it gets real old. So, what happens is we go through motor brushes
like they are on sale due to the excessive loading of the motors. With the
timer, it only raises enough to get the plow off the ground for the reverse
One more experiment i'm going to run is to trigger this timer with the
backup light circuit. This way everytime you put the truck in reverse, the
plow will raise. Another latching relay will lock out the "auto-up" so to
speak, until the plow has been dropped again. This way the thing doesn't
try to raise the plow numerous times if you backup numerous times before
With the Meyers plows, I used to just use a latching relay and a mercury
switch out on the plow itself to limit the raising of the plow. But this
will eliminate having the extra wires out in the weather and the fluctuation
of the mercury switch due to truck angle, jostling around, etc.
Thanks again for your help.
