b) How to work
Use great caution because the change from the transport to the work stage involves a
widening of the machine. Be aware of persons and objects that may accidentally be in
the vicinity. The change from the transport to work stage is simple and immediate. You
only need to send oil from the tractor (see step “b”, pg. 38-39) to the hydraulic circuit 1
of the machine so that cylinders 2-3 will retract. When retracting, cylinder 2 causes the
rake section 4 to rotate in the working direction G, while cylinder 3 retracting causes
wheel 5 to rotate in direction H so that it remains parallel to drawbar 10. Wheels 6-7 are
free and adjust their position following the trajectory determined by the tractor. The
working width can be controlled and changed from the tractor at any time. Each operator
establishes the correct width according to their needs and the forage conditions. (For the
various working widths, see page 8). Then, using the tractor hydraulic system 1, release
the oil from cylinder 8 so that it retracts and consequently brings the rake wheels 9 into
contact with the ground, i.e. in the working position. (Cylinder 8 is single acting, thus it
lowers due to the weight of the rake wheels 9, and therefore it will take a little while to
carry out the operation, especially when the oil is cold). For good raking of the forage
the teeth of the rake wheels 9 should brush lightly against the ground.
Now the actual work stage can begin, following the procedure A-B-C etc..
