Fault Cause
Remedy
The system converting bolt on the
spreader valve block has not
been unscrewed to the limit stop
(factory setting).
Unscrew the system converting
bolt on the spreader valve block
until it reaches the limit stop
(on page 72).
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
The temperature of the hydraulic
fluid is too high in a tractor
equipped with a constant flow
system (gear pump)
Defective tractor control unit
Check tractor control unit, re-
pair/replace as required.
The system converting bolt on the
spreader valve block has not
been screwed in to the limit stop
(opposite of factory setting).
Screw the system converting bolt
on the spreader valve block until
to reaches the limit stop
(on page 72).
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
The temperature of the hydraulic
fluid is too high in a tractor
equipped with a constant pres-
sure system (some older John
Deere tractors)
Defective tractor control unit
Check tractor control unit, re-
pair/replace as required.
The temperature of the hydraulic
fluid is too high for a tractor with
load-sensing system and oil re-
moval via the tractor control unit
The system converting bolt on the
spreader valve block has not
been unscrewed to the limit stop
(factory setting).
Unscrew the system converting
bolt on the spreader valve block
until it reaches the limit stop
(on page 72).
The quantity of oil at the tractor
control unit has not sufficiently
reduced.
Reduce the quantity of oil at the
tractor control unit.
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
Defective tractor control unit
Check tractor control unit, re-
pair/replace as required.
The system converting bolt on the
spreader valve block has not
been screwed in to the limit stop
(opposite of factory setting).
Screw the system converting bolt
on the spreader valve block until
to reaches the limit stop (on page
72).
The temperature of the hydraulic
fluid is too high for a tractor with
load-sensing system, direct oil
removal and control line
Defective plug couplings
Check plug couplings, re-
pair/replace as required.
