Track Width, Axles and Wheels

Procedure for Altering the Track Width

Instruction is valid for COMMANDER and NAVIGATOR sprayers.
The track width of the sprayer can be altered steplessly:
1. Measure the current track width (centre of right tyre to centre of
left tyre). Each side must be extended or retracted half the desired
alteration.
2. Connect the sprayer to the tractor and engage the tractor parking
brake.
3. Place stop wedges in front of and behind the right wheel. Jack up
the left wheel and support with trestles.
4. Loosen the bolts and counternuts (A) for the left wheel axle.
5. If a handbrake is installed, loosen the screw (B) on the brake
operating arm.
6. Extend or retract the wheel axle. A sack barrow and a rod, or a pallet
jack, will facilitate the operation.
7. Lower down the left wheel.
8. Tighten the clamp bolts (A) with a torque of 250 Nm and tighten the counter nuts. Lower the wheel to the ground.
9. Repeat the procedure on the right wheel.
10. Check if the distance from centre tyre to centre of rear frame is equal at the right and left side.
11. Retighten bolts and wheel bolts to the specified torque after 8 working hours.
μ
ATTENTION! The wider the track width, the better the stability of the sprayer. Use the widest possible track width.
μ
ATTENTION! Depending on the configuration of the sprayer, the track width can be altered in the range from 1500
mm to 2000 mm (narrow version), or from 1800 mm to 2250 mm (wide version), in combination of above
adjustments and turning of the rims (offset).
How to Find the Limits
• The two wheel axles will meet in centre (C) when pushed this way, resulting in the minimum track width.
• Extending the axles is allowed, as long as the bolts (D) are touching the axles when being tightened. By having both
axles ending on the line (E) this will result in the maximum track width.
€
DANGER! If the bolts (D) do not clearly touch the axle when being tightened, the axle is not secured. Risk of the
sprayer breaking apart when driving. Risk of fatal accidents.
