Subsoiler (Pro-Lift) Tines
Standard Wing
P09060
„ Maximum soil disturbance with
minimum draft requirement under
normal circumstances.
„ Wing angle reduces wear rates on leg.
Extra Lift Wing
P10392
„ Increased lift height and and rake angle
creates greater soil disturbance on all
soil types especially in moister
conditions.
„ Lower relative distance between edge
of wing and point reduces draft
requirement.
„ Has ability to work at lower depths with
no decrease in soil disturbance or risk
of smear.
Extra Wide Wing
P10411
„ Improved lateral shatter in moist/wet
soils, or non-cohesive soils.
„ Ideal for deep vegetable applications
under light/medium soils.
Pro-Lift Wings
Wear Shroud
P11181
„ Wear plate to take soil abrasion so
lower trailing edge of tine does not
wear.
Different wings are available to suit the soil
conditions and optimise the performance of
the machine when using subsoiler tines.
Tine depth is achieved by moving the tines
up and down in the adjustable clamps.

Furrower Tines
Furrower tines create ridges in the soil ideal
for root crop applications such as potatoes.
