Valtra 900 - F 4. Using the hydraulic lift

---55---
F. Operating instructions
different lateral positions for the lower links can be
obtained. If the pins are fitted in the long holes, the lower
links have a floating position in the lateral direction.
F 3.3. Telescopic lower links
When connecting an implement, pull from the link (B),
then the lower link will move to the floating position.
After disconnecting the lower link will lock when lifting the
implement.
When disconnecting the implement, pull the link (B) and
turn 1/4 turn (implement lifted up). Lower the implement
and move the tractor forward a few centimeters, this will
put the lower links in the floating position and allow the
implement to be disconnected easily.
CAUTION: Turn the links anti-clockwise to the down
position when connecting the implement.
F 4. Using the hydraulic lift
F 4.1. Using the mechanically controlled hydraulic lift
A3565---66
The hydraulic lift is operated by means of:
--- Position lever
--- Draft control sensitivity (by changing the place of the
top link)
--- Lowering speed control
DANGER: When transporting tractor mounted
implements it is essential that the check links of the
lower links are locked with the cotters.
F 4.1.1. Position lever
3
1
65---42,1
Move the lever (3) backwards to raise the lower links and
forwards to lower them. When the position lever is set in
an intermediate position, the lower links move to a
corresponding height.
NOTE: Lock the position control lever with locking
device (1) in the rearmost position (lower links at top)
when transporting an implement mounted on the
three---point linkage.
When working with position control only the pawl for the
top link bracket (impulse sender pawl) should be in the
locked position (lever in horizontal position).
The position control is used when working with
tractor---mounted machines (mowers, centrifugal
broadcasters, plant sprayers etc).
With the limiter (1) of the position control lever (3) the
lower links can always be lowered to the same position.
F 4.1.2. The floating position
The floating position is used when working with
implements which are provided with support wheels or
similar. Push the position lever forward as far as it will go,
when the lower links and working implements can move
freely up and down.
