Field Operations--Implement
Checking Electrical Signal Continuity and Electrode Isolation
It is recommended that you perform the Electrical Signal Continuity and Electrode Isolation test
procedure before first field use (see Maintenance and Service Procedures 1 and 2). While these
tests were made at the factory, there is the possibility a problem developed during shipping.
Performing these tests on the new implement before it becomes dirty, allows you to get familiar
with the process under ideal conditions. It is strongly advised that you perform this test on a routine
basis (every 10 hours of data collection) to ensure you are obtaining reliable data. KEEP
OHMMETER, TEST LOAD AND TEST BOX WITH THE MACHINE AT ALL TIMES.
Equipment pre-mapping check
Prior to operating the implement for the first time, it is important to check the fasteners
– some may
have loosened during shipment. Routine fastener checking should be done weekly during
mapping season and a walk-around check of the implement components should be done each
day.
Setting Operating Depth
Begin field operation by lowering unit into soil. For good
electrical conductivity, all disk electrodes must be in direct
contact with moist soil, at all times and in every region of
the field. A depth of 1-
2” (2.5-5 cm) is recommended
(Figure 13). To insure this depth is consistently achieved,
400 lbs (180 kg) of additional weight are normally
required. Veris offers optional weights, or they can be
supplied by the customer. Lower unit until proper disk
depth is achieved, or until wheels are slightly (<.5 inch/ 1
cm) off the ground.
Field Condition
Field should be in a uniform state. Mapping after intensive primary tillage is not recommended. The
soil must have a minimum of 20% available water, and cannot be frozen. If rocky conditions exist,
slow down.
Speed
Proper field operating speed depends on field conditions. Because of the importance of consistent
contact, the unit must not be allowed to bounce over rough fields at high speeds.
• Be very careful when mapping stubble fields using a vehicle with a gasoline engine. Be prepared
if a fire starts. Keep crop residue and other debris from accumulating near the exhaust and in
engine compartment.
