Row Unit Operation
QUICK ADJUSTABLE DOWN FORCE SPRINGS OPTION
Quick adjustable down force springs increase penetration in hard soil and keep row unit from bouncing in rough field
conditions. Two springs per row, one on each side parallel arms, are used unless equipped with row unit mounted no
till coulters. Four springs per row are used with row unit mounted no till coulters.
1. Raise planter and remove spring mount pin at top of spring.
2. Slide mount to desired position and install pin.
NOTE: Adjust springs for field conditions. Too much down pressure in hard field conditions can cause
row units to lift planter and keep drive wheels from making contact. Too much down pressure in soft field
conditions can cause row unit to run too deep.
There are four positions for spring tension adjustment. Position 1 sets minimum down pressure and position 4 sets
maximum down pressure.
