Condition
Possible Cause
Correction
__________________________________________________________________________________________
Machine stops aerating (pump
shuts down during aeration).
Machine not moving.
Normal condition of interlock sys-
tem. Operator must hold engage
button in to aerate with traction
bail in neutral.
Inadequate water supply.
Plugged inlet water filter.
Check for kinked water supply
hose, restriction in line or partially
open valve at water source.
Check water pressure at gauge
when pump is engaged. If pres-
sure drops to less than 15 PSI,
but was initially higher, replace
water filter.
Electrical problem.
See Troubleshooting in
Chapter 5 - Electrical System
________________________________________________________________________________________________________________________________________________________
Water system engages (pump
belt and gear case drive shaft
rotate), but no aeration holes are
produced or aeration hole depth
is shallow or inconsistent.
Air in system.
With engine OFF and water supp-
ly connected, open high pressure
bleed valve and bleed air out of
system.
Soil density or moisture content.
If hole depth was satisfactory
before in another area, different
nozzle configuration may be re-
quired.
Plugged nozzles, worn nozzles or
improper nozzle configuration.
NOTE: Check operation of nozzles
by aerating over a piece of
cardboard, then inspecting
cardboard.
Stop engine, open high pressure
bleed valve, then inspect noz-
zles. Check for plugged nozzles.
Verify size and quantity (see Noz-
zle Size and Approximate Depth
Chart). Nozzles that are too large
will cause loss in pressure and
could cause damage to the ac-
cumulator and other water sys-
tem components.
Gear or cam damage in gear case.
Inspect gear case for gear or
cam damage and repair as neces-
sary.
Leak in high pressure water sys-
tem.
Check for leaks with water sys-
tem engaged. Stop engine, open
high pressure bleed valve and
repair leaks as necessary.
NOTE: Excessive water exiting
between pump head and
crankcase indicates pump wear
or damage. Excessive water exit-
ing from shim area below gear-
case indicates valve wear or
damage. Do water system tests
and make repairs as necessary.
