Altering the track width

The track width of the sprayer can be altered stepless as follows,
Altering procedure
1. Measure the current track width (centre RH tyre to centre LH tyre).
Each side must be extended or retracted half the desired
alteration.
2. Attach the sprayer to tractor and engage tractor parking brake.
3. Place stop wedges in front of and behind RH wheel. Jack up LH
wheel, support and secure sprayer body.
4. Loosen the counternut at the bolts (A) and the bolts (A) for LH
wheel axle.
5. When having a handbrake, loosen the pointed screw (B) on the
brake operating arm.
6. Extend or retract the axle. A sack barrow and a rod will facilitate the
operation.
7. Lower down the LH wheel.
8. Tighten the clamp bolts (A) to a torque of 250 Nm and lock the
bolts with the counternuts.
9. Repeat the procedure on RH wheel.
10. Check if the distance from centre tyre to centre of rear frame is equal at RH and LH.
11. Retighten bolts and wheel bolts to specified torque after 8 hours of work.
ATTENTION! The wider the track width, the better the stability of the sprayer. HARDI recommends to work with widest
possible track width.
ATTENTION! Depending on configuration of the machine 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 adjustment and
turning of the rims (offset).

Turning rim

Track width can be altered by turning the rim.
Offset:
+ 61 mm
- 50 mm
ATTENTION! When wheels has been mounted or re-tightened,
the plastic nut covers must be placed on the nuts afterwards.
