This is the pressure 
reducing, relieving valve, 
which is electrified when 
your packing switch is 
turned on. This valve 
maintains packing 
pressure on your 
openers during seeding. 
This is the packing 
and penetration 
motor. Your shank 
pressure switch in 
the cab controls the 
motor. 
This is the dump line 
pressure gauge. Ideally this 
has no pressure while 
seeding. You may operate 
up to 100 PSI. 
This is the IN pressure 
gauge. This reads what 
pressure you tractor 
pump is putting out. 
This is the wing lift pressure 
gauge. While seeding it will 
read 0, it will pressure up 
when lifting the wings. 
This is a 4” shank pressure gauge 
with a maximum 1500 Psi. Every 
new Seed Hawk is set at 1200 Psi. 
Please refer to pages 29-31 which 
illustrates how to set the correct 
packing pressure and trip pressure 
relevant your field conditions. 
This is the wing down 
pressure gauge. It is preset 
for your width of machine. It 
will show this preset 
pressure while seeding.
