Machine Offsets

A - Lateral distance from center-line of machine to GPS receiver

B - In-line distance from non-steering axle to GPS receiver

C - In-line distance from non-steering axle to connection point

D - Vertical distance from the GPS receiver to the ground

E - Offset Toggle Button

F - Non-Steering Location Drop-Down Menu

In-Line distance from non-steering axle to GPS receiver (B) will be

• Row crop tractors—rear axle
• Articulated tractors—front axle
• Track tractors—rear axleNOTE: Offset (B) for track tractors should be measured from the receiver to the pivot point.
  

Offset Toggle button (E) toggles the receiver from the left side of machine to the right side.

Verify that the correct connection point is selected and measure from the center of non-steering axle to the center of connection point (Example: center of drawbar pin or lower links, except in the case of a rear pivot 2-pt mount—measure to the pivot point of the implement tongue).

NOTE: Offset (C) will change when the connection point changes.

IMPORTANT: Offsets must be accurate because they will be used to calculate the guidance path for iGuide.

Track Machines

X - Pivot Point

Y - Tractor Tracks

1. On Track machines, the non-steering axle should be selected as rear axle.
2. Offsets B and C should be measured to the turning point or pivot point of the machine. For example: when turning machine, it usually does not rotate on the rear axle but somewhere in front of the rear axle.

This dimension can be measured by turning the machine in a fairly tight turn, such as an end turn. Stop half way through the turn. Looking at the inside track and its relationship to the tracks on the ground, determine the pivot point of the machine. Vehicle ballasting and drawbar load could affect these offsets.
