7.0 DRIVING SPEED
Fig. 13
The hole separation D, fig. 13, in the driving direction is determined by the drive speed. The
Verti-Drain
®
does not require creep gear. If the client wants a small hole distance, however,
it must be possible to ride slowly enough, which depends on the tractor.
The input speed of the PTO shaft may not exceed 500 rpm.
If hard objects are expected, this speed must be reduced and the transmission must
be put in position 1.
With heavier pins, other applications, or with maximum pin angle, the pin holders may float.
In this case, reduce the speed before the pin holders are forced upward.
Fig. 13 contains a table showing the relationship between the driving speed and the hole
separation. If the driving speed of the tractor for 500 revolutions of the PTO shaft is known,
the hole separation can be determined.
@ If the Verti-Drain
®
is not correctly attached behind the tractor, see fig. 8, various PTO
shaft angles can cause vibrations in the driveline of the machine. These vibrations can
damage the machine and the holes in the ground.
@ If the PTO shaft was shortened incorrectly, or if another tractor was used, the gearbox
may be overloaded. Damage can occur.
