This photo shows the steering post being rotated 180 degrees. This takes only a couple seconds. You detach the rods (by unsnapping them from the column) controlling the transmission and
PTO (you can see the rods laying on the tires), pull the release lever (on top of the column) and swing it around. The means the
PTO (at the lower left in the photo) can point forward (for mowers, etc.) or to the rear (for tillers, rotary plow, etc). Also, the handle bars adjust up and down on the column by pulling a lever.
The column also swings out (you can see three positioning holes directly to the left of the column) so that you can walk to the side when tilling. Just to the left of the three holes you can see two pieces of metal sticking out (one above the other) with holes on the end. This is used to attach towed equipment. Also visible in a photos below.
