(57) An apparatus for removing water from the ground comprises at least one ground-engaging
drum (10) including a hollow cylinder (11) mounted for rotation about a substantially
horizontal axis, and a plurality of recesses (13) substantially parallel to the rotational
axis of the cylinder formed in the outer surface of the cylinder around the periphery
thereof. A non-porous sheet (14) of resilient material covers the outer surface of
the cylinder, and a plurality of slits (15) are cut in the covering sheet over the
recesses in the cylinder. The slits are normally closed but are capable of opening
under the pressure of water (21) built up in front of the drum, as the latter is moved
across the ground, to permit such water to enter the recesses (13) in the region of
ground contact. The slits close away from the region of ground contact to retain the
water in the recesses, and apertures (16) in the recesses permit water retained therein
to discharge into the interior of the cylinder at a certain height within the cylinder
for collection in a water tank (17) within the cylinder.
