Checking The Springs; Adjusting The Hole Spacing; Removing The Aerator From The Tractor - Toro 09930 Operator's Manual

Checking the Springs

Service Interval: Before each use or daily
Check the springs for crossed or broken wires
(Figure 46). Crossed or broken spring wires will cause
an erratic hole pattern in the turf.
1. Correct spring wires
Note: Replacement wires are included with the aerator.
The wires are considered a consumable item.

Adjusting the Hole Spacing

The forward hole spacing is determined by the tractor's
gear ratio (or the hydrostatic traction pedal). Changing
the engine RPM does not change the forward hole
spacing.
The lateral hole spacing is determined by the number
of tines in the tine heads.
