Implement Offsets—Used to define the actual implement
position relative to the tractor. This is important for
ensuring the implement is lined up to the field at the end
of turns and in determining where the implement is for
the Minimize Skips and Minimize Overlaps feature (see
Change Settings on Machine tab).
• A) In-line distance from connection point to front of
implement. On pull-type implements, think of this as the
tongue. For more precision, it is actually the dimension
from the pinbolt to the front side of where the work gets
done (front ranks of field cultivator, seed drop point on a
planter). For planters with a 2 pt. mount, measure from
where the planter pivots just behind the 2 pt.
• B) Working Length of the implement. On ground
engagement tools, this is the distance from the front
rank of sweeps or points to the rear rank. On a standard
planter or pull type sprayer, this dimension would be 0
- the seed is dropped at the same point on every row,
and the sprayer has nozzles at the same point along
the boom. Dimension (A) would then need to extend to
the location of the seed drop point or sprayer boom. On
a spreader, (A+B) is the drop point of the product. Refer
to manufacturer's implement OM for this value.
• C) Lateral distance from connection point to control point
of implement. This is the lateral distance from the center
of the tractor to the center of the implement, which will
be 0.0 for most common implements. This dimension is
used to alert the operator to potential collisions. This is
critical for proper end-turn performance and may need
to be adjusted.
NOTE: Examples of equipment that will not be centered
include mower conditioners and most split row
planters with an even number of 38 cm (15
in.) rows, (e.g. 24R15 or 32R15) unless you
have an adjustable hitch crossbar.
• D) In-line distance from connection point to control
point of implement. In many cases, this distance will be
from the connection point to the carrying wheels. For
proper turns, measure this distance with implement at
the height it typically will be at while turning.
NOTE: These dimensions may need to be adjusted
for fine-tuning performance in the field.
NOTE: For 3 pt mounted implements, dimension
(D) does not need to be entered.

Typical Planter Setup—JD 1770 16R30 NT planter with
a 2 point connection
• A = 3.8 m (12.6 ft)
• B = 0 m (0 ft) - even though it is physically 2 m (6.8 ft)
• C = 0 m (0 feet)
Typical Disk Setup—JD 637 F 10.8 m (35.5 ft) disk setup
• A = 3 m (9.9 ft)
• B = 5 m (16.4 ft)
• C = 0 m (0 ft)
