17.1 OPTIONS, TINES
Tines are essential for the correct operation of the machine. There are various tines
available for this machine; see the parts page for a complete overview. In general, the tines
can be divided into two categories: solid and hollow tines. We recommend only using original
tines because they are completely adapted to the machine.
The pin holders have 3 x 12 mm (½”) holes in which tines can be secured.
Locking bolt A may be tightened to 40 Nm (29.5 lbf.ft.). (Fig. 29.)
If the tines come out of the pin holders, grind a flat area on the mounting end of the tines.

17.1.1 SOLID TINES
Solid tines break open compacted soil. The tine angle adjustment (see chapter 6.0)
determines the quantity of heave movement in the ground. When the angle is adjusted from
90 to 75 degrees, the draught movement increases. With a 90 degree adjustment, there is
almost no heave movement created in the ground.
When the tines are new, they may damage the turf, in particular when the root system is
weak. First clean the tines manually or use the machine first for 10 minutes on another rough
ground surface.
When the root system is weak, try to adjust the operation depth such that the penetration
depth is slightly deeper than the length of the roots. This gives the roots a chance to grow
deeper. Aerate deeper the next time. By using this method, you can prevent damage to the
turf and ensure a healthy root system.
We recommend using the solid tines with the sharp point towards the front roller.
This ensures the best tine movement into the ground. On the other hand, for weak
turf, we recommend using the tines with the sharp point towards the rear of the
machine.
Always use tines with the same diameter and length. Replace a bent pin immediately. If this
is not done, the machine can become unstable. Do not use thicker and/or longer tines than
we supply.
Shorter (ground off) tines can be used when shallower aeration is desired. Be aware that the
operating depth indicated on the sticker is only accurate when the maximum length of the
tine is used.
When oval holes are created, this means that there is a weak top layer with a hard layer
underneath. Use thinner tines or wait until the (wet) top layer has dried.
When top dressing must be applied, apply it before using the Verti-Drain
®
.
When the ground is difficult to aerate, water the soil first, use thinner and shorter tines, or
adjust the operating depth. If these measures are not taken, the machine will eventually be
damaged.
