Problem
Transport/Towing
1. Spreader tending to shunt or bounce in
tractors hitch.
Possible Solution

Check tractors drawbar pin size.
Replaceable collar in the spreader tongue
has been designed for a 1-
1/2” (38mm)
pin.

Make sure that the load has been placed
evenly in the spreader. Load will shift
rearward as the product is spread.
Spinner Operation (Ground Drive Model)
1. Spinner Speed Varies during operation
or unable to obtain maximum speed
(780rpm).

Check that the handle on the flow control
valve, located on the inside of the trailer
frame at the front of the spreader, is in
the open position, handle against the
stop bracket (page 19).

Some variation in spinner speed will
occur when an irregular load is placed on
the spinners i.e. product falling in large
clumps into the spinners. This is normal.
Tachometer Display(Ground Drive Model)
1. Tacho does not display when the
spinners rotate.

Check that the sensor has not been
damaged.

Check that the sensor wire is intact.

Check battery voltage. Use a replaceable
3.6V AA battery. Please contact your
Gason dealer for further information
regarding spinner tacho repair.

will effect spread pattern (refer page 13
for suggested speeds).

Centre Vee panel may need to be
removed for certain products (page 10).

product type and spreader setup. Refer
to pages 13-17 for more information.

used for pelletised consistent products
only.
