17.1.2 HOLLOW TINES
The ground can be mixed with hollow tines. Various sizes are available; see the parts page
for more information. The opening of the tine must be directed toward the rear of the
machine.
For hollow tines it is important that the tine angle is set to 90 degrees. The movement of the
tine in the ground is minimal and in this manner a nice “clean” hole is made. When the tine
continuously moves in the ground at an angle less than 90 degrees, the tine may eventually
break.
When top dressing must be applied, use the Verti-Drain
®
first, remove the “cores” and then
spread the sand.
When lots of waste occurs while aerating with hollow tines, reduce the rotational speed or
wet the soil first. The waste can increase the rate of wear to your machine.
If the turf is damaged, first use solid tines to establish a healthy root system and then adjust
the operating depth.
When the hollow tines become plugged, this means that the ground is (very) compact and
solid tines must be used first to break the ground open. Wetting the soil or adjusting the
operating depth can also help solve this problem.
17.1.3 MULTI TINE KIT
You can aerate with smaller tines than 12 mm with a multi tine kit. Available in both solid and
hollow tines. See the parts page for specifications.
17.1.4 CROSS TINES
Cross tines are cross-shaped tines that provide a cross-shaped hole pattern. See the parts
page for specifications.
17.2 OPTIONS, CORE COLLECTOR
If hollow tines are used to aerate with, cores can be removed from the soil. The core
collector ensures that the cores are guided neatly together after the Verti-Drain
®
operation,
after which they can be easily removed. The kit can be supplied under number 211.700.006.
See the parts page.
You must also mount the rear roller kit to be able to use the core collector. The core collector
is attached to the rear roller.
17.3 OPTIONS, REAR ROLLER
The Verti-Drain
®
is not fitted with a rear roller as standard.
If desired, a rear roller can be supplied under number 211.700.028. See parts page.
The kit consists of a rear roller with adjustable scraper, and the fixing legs with assembly
material for attachment to the Verti-Drain
®
.
