Wheel height adjustment :
The left and right wheels must be adjusted so that the
rotors are level.
The height of the GA 7301 is correct when the
tines slightly skim the ground while the rotors are
in the horizontal position (see “rotor horizontality”,
page 17).
The adjusting system for the wheel height consists
of :
- a vertical sector (A) with 7 holes,
- a pin operated by the lever (B) (photo 36).
Central swath screen
To lower or raise swath screen (C), free crank (F) by
pulling out linch pin (A) (diameter 8) and rotate crank in
one or the other direction (photo 39). Lock again crank
(F) with support (G) using linch pin (A) when correct
screen height has been selected.
The housing of the axle (D) has on its outer side four
notches which correspond to the holes 1, 3, 5 and 7
of the sector (A). The three spaces between the
notches correspond to the holes 2, 4 and 6 (photo 37).
The roll pin (C) is used as a marker for the height
adjustment of the wheels (fig. 37). Initially, it is
recommended to engage the pin in the fifth hole of
the sector (A).
Height adjustment of the wheels is carried out as
follows :
- Raise the rotors until the axles (Y) are butting
against the pawls (R) (photo 6, page 12).
- Free the pin of the vertical sector (A) by pushing the
lever (B) away from the wheel and in the direction
of the arrow (photo 38).
- Raise or lower each wheel by one or more holes
(positions 1 to 7, photo 37).
- Lower the rotors on the ground.
Note :After each wheel height adjustment, make
sure that the pin is fully engaged in its
housing in the vertical sector.
Note : To adjust the wheel height on the bogie
axles on GA 7301 USA, refer to page 27.
