use it for implements of different widths without hitting the fence, as the a-b line is on the edge of the field next to the fence, or do i have to save several fields with the a-b line for each implement.
The Trimble 500 drops the AB "flags" from the center of the implement to create your AB0 line. The autosteer puts the center of the implement on your AB0 line. All other passes are generated from your AB0 line based on your width, offset, overlap, etc.
The usual work around is to (Say you're making your fence AB line with a 30' planter)
- Create your AB line along your fence
- Shift the AB line over 15 feet, putting the AB line at the edge of the field
- Save that line as "Fence AB"
- For every field operation you'll shift that line over half the implement width when you pull into the field. This is a simple thing to calculate when your implement has no offset or overlap, quickly becomes confusing with overlap and a nightmare with offset. So you end up just lining it up by eye and hitting "shift to here" instead.
AgOpenGPS, the open source autosteer program that I use, uses "edge reference." The AB "flags" are dropped off the edge of the implement. The autosteer system puts the edge of the implement on that AB0 line. You never have to shift anything, no mental calculations, it just works every time easy as can be. Takes care of all the offsets and overlap. Its a recent feature and it's awesome. Basically like that Trimble headland mode, but for every kind of curve/line/pivot/headland.
