Connecting the rake to the tractor
After the rake has been attached to tractor, check the balance and steerability of tractor - rake
set. In order to perform this, calculate to formulas given in the appendix or weigh the set, and
then drive on the scales only with front axis of the tractor. If the pressure on the front axis is at
least 20% of the whole set’s pressure, it means the set is stable. Otherwise, front axis should be
balanced.
5.2. Preparing the rake for transport
CAUTION:
Switching the machine from working to transport position, and the other way
round can only be done on an even and stable ground. Prior to starting any
works make sure that nearby the machine there are no unauthorized persons
exposed to being crushed.
