Towed Units
Raise sampling mechanism to full height. Begin depth adjustment process with shank in center
position (pin in one of two center holes). Install 2-
3“ (5-7.5 cm) of cylinder depth stops on main lift
cylinder. Lower implement into soil until main lift cylinder bottoms out against depth stops. Adjust
threaded top link to level unit.

Once unit is level, lower sampling mechanism completely, drive forward 10-
20’ (3-6 m) to create
soil core. To measure depth of soil core being collected, brush away soil from cutting shoe.
Measure from soil surface to top of cutting shoe. This is the depth of sampling. To increase
sampling depth, remove cylinder stops; to decrease sampling depth, add stops. Re-leveling unit
with adjustable top link may be required.

Operate implement parallel to soil or
slightly
tipped (up to ½”) forward never allow
unit to tip backward --this will decrease shoe
penetration.
