Adjusting Weight Transfer; Additional Weight; Aerator Control Module (Acm) - Toro ProCore 648 Operator's Manual

some additional weight transfer may be required. To
increase the down pressure of the weight transfer springs,
proceed as follows:
Warning
Sudden release of the spring plates could cause
injury.
Acquire the help of another person to help adjust
the weight transfer spring.
1. Loosen the carriage bolt nuts securing the spring
brackets to the coring head. Do not remove (Fig. 37).

2. Insert a 1/2 inch rachet or breaker–bar into the square
hole in the spring plate (Fig. 38).

3. Hold the rachet or breaker–bar to relieve the tension
on the spring plate and remove the rear carriage bolt.
4. Rotate the spring plate until it is aligned with the other
hole, insert the carriage bolt and tighten nuts.
Note: Rotating spring plates upward will increase weight
transfer.

Additional Weight

With the increased weight transfer, it is possible to aerate
firm enough ground that the weight transfer begins to lift
the rear two tires off the ground. This may lead to
irregular hole spacing.
If this occurs, an additional weight plate can be added to
the rear frame axle tube. Each cast weight adds 63 lbs
(28.5 Kg) to the traction unit. Up to two plates can be
added. Refer to parts catalog for these part numbers.

Aerator Control Module (ACM)

The Aerator Control Module is a "potted" electronic
device produced in a "one size fits all" configuration. The
module uses solid state and mechanical components to
monitor and control electrical features required for safe
product operation.
Figure 39
1. Standard control module
The module monitors inputs including head low, head
high, transport, aerate and ground following. The module
is divided into inputs and outputs. Inputs and outputs are
identified by green LED indicators mounted on the printed
circuit board. Power is identified by a red LED indicator.
The start circuit input is energized by 12 VDC. All other
inputs are energized when the circuit is closed to ground.
Each input has a LED that is illuminated when the
specific circuit is energized. Use the input LED's for
switch and input circuit troubleshooting.
