6.0 DRIVING
SPEED
Driving speed is limited to 12 km/h (7.5mph).
We advise against going any faster because that could lead to excessive wear and damage to the
machine and the treated lawn.
Hole spacing in the driving direction is determined by the driving speed.
The input speed of the PTO shaft must not exceed 540 rpm. If you expect to encounter any hard
objects on your path, this speed should be lowered to 200-300 rpm.
Refer to technical specifications for an overview of the relation between tractor speed
and hole spacing.
If the Verti-Core III is connected to the tractor incorrectly, Chapter 4, Fig.11, different
PTO shaft angles can cause vibrations in the machine’s drive shaft. These vibrations can
damage the machine and negatively affect the pattern of holes in the ground.
If the PTO shaft length is set incorrectly (too short or too long), the gearbox and/or
tractor PTO shaft can be subjected to additional load. This can cause damage.
7.0 STARTING PROCEDURE
The starting procedure is VERY important. If this procedure is not adhered to as described below, the
machine can become seriously damaged. The starting procedure is as follows, see Fig. 11.
1. Drive to the spot where you want to start the work.
2. Lower the machine until the lowest tines almost touch the ground.
3. Rev the tractor engine up to about 1000 rpm.
4. Shift the tractor to the right gear and drive forward (A).
5. Switch on the PTO shaft of the tractor (B).
6. CAREFULLY lower the RUNNING machine into the ground as the tractor is moving forward (C).
7. Raise the PTO shaft rpm to the maximum permissible value.
