2) WHEEL TRACK ERADICATORS
In order to reduce the tractor wheel marks left on the seedbed, the power harrow may be equipped with wheel track
eradicators. Depending upon the working conditions, 2 types of track eradicators may be ordered.
Each track eradicator set is made up by :
- 1 set of tine holders
Ref. 123 8520
- 1 set of 2 track eradicator tines
Ref. 123 8530 for the traction bolt overload mechanism
Ref. 123 8540 for the adjustable spring overload mechanism
Bolt rails (S) onto their mounting brackets.
The eradicator tine mounting yokes (C) are to be fitted on the rails (S) in such a way as to have the nuts
positioned at the front as shown on photos (A and B), to avoid any interference when a front levelling bar is
mounted.
The height of the leg (L) with reversible share (F) can be adjusted according to the depth of the wheel tracks by
means of a pin (N) (photos A and B). Nevertheless, the working depth of the shares must never exceed 100
mm (4").
The track eradicators are equipped with an overload mechanism should they encounter an obstacle :
- with traction bolt (T) (photo A) : breakage of the bolt (ref. 801 310 51) with its nut (ref. 802 010 30)
- with adjustable spring (U) (photo B) : the tine clears the obstacle and regains automatically its position.
Recommended in difficult or stony grounds.
The track eradicators must be mounted centred with regards to the tractor wheels, one per wheel (photos C and
D). In the case of dual wheels or large tyres, additional track eradicator tines can be fitted (to be ordered under
n° 123 8530 or 123 8540).
NOTE : Track eradicators are only to be used for secondary tillage work.
