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, shorten ratchet jack; to decrease sampling depth, lengthen ratchet jack. Re-
leveling unit with adjustable top link may be required.

Note: if MSP is equipped with EC Module and EC data is being collected along with pH data,
adjusting the overall height of the unit will affect coulter-electrode depth. If deeper soil sampling is
desired, and shortening ratchet jack would result in excessive coulter-electrode depth, remove
sampler shank pins and lower shank to lowest setting. If shallower soil sampling is required, and
lengthen ratchet jack results in inadequate coulter-electrode depth for EC data collection, raise
sampler shank to highest setting.

Once EC coulter depth and sampling depth are satisfactory, adjust other components in this
sequence:
1. Scraper adjustment: in manual mode hydraulically raise the sampling shoe to maximum height.
Adjust scraper until cutting shoe clears scraper blade when sampler shank is fully raised.
