New Holland TJ series four-wheel-drive tractors
Kondinin Group evaluated the New Holland TJ series tractors based on a survey of 15 farmers asking them to rate their
machines’ performance and reliability.
O
wners of New Holland TJ series
four-wheel-drive tractors praised the
machines for their engine power, cabin
comfort and visibility.
But a Kondinin Group survey of 15 owners
also revealed that several farmers had
problems with leaking differential seals
and fluctuating temperatures for the airconditioning system. Despite this, all owners
would buy the same or similar tractor again.
The tractors had worked an average of
1087 hours.
The tractors, manufactured at Fargo, North
Dakota, United States, were released into
Australia during 2001. There are 13 versions
across six four-wheel-drive models within two
chassis sizes — four small-framed models (910millimetre wide using 10mm chassis plate):
TJ275 and TJ325 (available as Syncro or
Powershift versions) as well as nine largeframed models (1.12-metre wide using 12.7mm
chassis plate): TJ375 and TJ425 (Syncro,
Powershift or scraper), TJ450 (Powershift or
scraper) and TJ500 (Powershift only).
Engine #####
The TJ275 model has an in-line six-cylinder,
8.3-litre Consolidated Diesel Corporation
(CDC) diesel engine, the TJ325 model is
fitted with a 9L CDC diesel engine, while
the remaining models have six-cylinder, 15L
Cummins diesel engines. All models have
turbocharged engines and are aftercooled.
Organisation for Economic Co-operation
and Development (OECD) tests show power
at rated engine speeds of 2000 revolutions per
minute (rpm) range from 178.2 kilowatts
(TJ275) to 298.8kW (TJ450).
All owners surveyed rated the engine highly,
praising its reliability, torque and power.
Fifty-three per cent of owners said engine
power was one of the tractor’s best features.
Owners of the New Holland TJ series tractors praised their engine reliability and cabin visibility but several owners
had problems with leaking differential seals. Inset: Most owners (93 per cent) were happy with the placement and
use of controls and instruments but 27% raised concerns with the air-conditioner's climate control.
Fuel tank capacities range from 758L
(TJ275 and TJ325) to 1136L in the larger
models (TJ375–TJ500). Most owners (85%)
said this exceeded their expectations.
About two-thirds of owners (64%) praised
the fuel economy. According to OECD tests,
fuel use at rated engine power ranged from
51.5L per hour (TJ275), up to 83.7L/h (TJ450).
One Western Australian owner of a TJ375
model experienced excessive fuel use due to
incorrect fuel pump wiring. The problem
was repaired under warranty.
Two owners of TJ375 models reported
starter motor problems: one Queensland
owner rebuilt the starter after 650 hours of
use and replaced it after 1800 hours, while
one South Australian owner replaced his
starter after only 50 hours but has not had
a problem since. All items were replaced
under warranty.
One WA owner of a TJ425 model replaced
three different brand batteries under
warranty. The same owner also had oil
leaking from the exhaust manifold since new,
which has yet to be repaired.
Transmission ####
All TJ series tractors have an optional
24-speed, hi-low, synchro-shift transmission
or 16-speed, full powershift transmission.
Of the 15 owners surveyed, 11 praised the
smoothness of the transmission, two owners
of synchro-shift models were happy with
their machines, while two owners of full
powershift versions rated their tractor's
smoothness of gearshift as fair. Most owners
(93%) praised gear suitability.
Four owners reported oil leaks from around
the differential housing. Two Victorian owners
of TJ375 models had repairs carried out — one

owner said oil leaked from the front and rear
pinion seals and wheel seals after 150 hours of
use (replaced under warranty) and the other
replaced a leaking rear differential seal
(without warranty).
One WA owner of a TJ425 model said the
front right axle seal and the differential pinion
seal leaked. Both were replaced under warranty.
The fourth owner, a WA farmer with a TJ325,
reported chafing on the transmission hoses.
Another WA owner (TJ450) experienced
problems with the computer registering the
brakes and park brake as ‘on’ when they actually
were ‘off’. This was fixed under warranty.

Hydraulics ####
All models have a closed centre, load-sensing
hydraulic system. Most owners were satisfied
with the hydraulic system and capacity.
According to OECD tests, TJ275–TJ375
models deliver up to 131 litres per minute at
169 bar at maximum hydraulic power from
one port, while the TJ450 model was reported
to deliver up to 134.8L/minute at 169 bar.
Two owners surveyed reported problems
with auxiliary spool valves. One Victorian
owner of a TJ375 replaced the valves after 300
hours of use (under warranty) and has not
had a problem since, while another TJ375
owner from SA experienced minor problems.
For one New South Wales owner of a TJ425,
the hydraulic hoses rubbed through but were
replaced under warranty. An upgrade for the
hydraulic system is available. A high-flow pump
can be added to increase hydraulic capacity up to
212L/minute at 169 bar (OECD tests).
Linkage and PTO ####
All TJ series tractors can be fitted with an
optional 1000rpm, 21-spline power take-off
(PTO). Of the 15 owners surveyed, only one
NSW owner of a TJ325 model had the
optional PTO. While it performed well he
reported that the hydraulic lines were
installed incorrectly, causing the oil to
overheat. This was repaired under warranty.
A category IV-N three-point linkage with
adjustable quick-hitch is optional on all
models except the TJ500. The linkage arms
have a maximum lifting capacity of 7100
kilograms (TJ275), up to 8900kg (TJ450), as
tested by the OECD. None of the tractors were
fitted with the optional three-point linkage.
Drawbar performance #####
Tractors were used for cultivation and
sowing (48%) at 8–10 kilometres per hour,
laser bucket work (18%) at 8–12km/h, primary
tillage (16%) at 8–10km/h and spraying and
transport (18%) at 12–15km/h. Work was
carried out under full load (23%), heavy load
(47%), half-load (20%) and light loads (16%).
Eight owners rated pulling power as one of
the tractor’s best features. One WA owner of
a TJ425 also praised flotation, claiming it
resisted bogging.
Tyres and weights ####
All tractors in the survey were fitted with
radial tyres with most owners checking tyre
pressure monthly or six-monthly. Front and
rear 620–70R42 dual tyres were popular, along
with 710–70R42 sized tyres. Owners expected
their tyres to last an average of 5167 hours.
Of those surveyed, 62% of owners used cast
ballasting on their tractors. The remainder
did not ballast the tractor at all. Two owners
from Victoria and WA of TJ450 models that
used cast ballast reported minor tyre bounce.
Cabin and controls ####
Almost two-thirds of owners (60%) praised
the tractor’s air-conditioning and heating

system but 27% experienced some problems.
For example, one Victorian owner of a TJ375
model said there were major temperature
fluctuations in the climate control system,
which have yet to be fixed under warranty.
One NSW owner of a TJ425 said the condenser
was too small to function in hot temperatures.
All owners praised the ease of cabin entry
and cabin visibility, with 53% of owners rating
visibility as one of the tractor’s best features.
Seat comfort, seat adjustment and operator
comfort also rated highly although one SA
owner of a TJ375 stated the seat was not
well-designed for short operators. Generally,
owners said the cabin was relatively quiet.
Most owners (93%) praised the placement
and use of controls and instruments and only
one SA owner (TJ375 model) rated the
controls as satisfactory.
Eighty-six per cent of owners praised the
standard lighting but one NSW owner of a
TJ325 model rated it as satisfactory, while one
Victorian owner of a TJ375 said it was fair.
While most owners praised the radio, one
Victorian owner of a TJ375 rated it as fair
without giving a reason. Almost two-thirds
(64%) of owners surveyed were satisfied with
the ability to fit a two-way radio or phone, with
the remainder stating it was fair.
One Victorian owner of a TJ375 believed
the air intake for the cabin air-conditioning
system was poorly placed — it was at the rear
of the cabin roof where it was prone to dust.
Servicing ####
All owners praised the ease of daily
servicing but one WA owner of a TJ450 was
unhappy with the major service because of
poor access to oil filters. One Queensland
owner of a TJ375 tractor also said the bonnet
latch needed to be strengthened.
All owners were satisfied with the ease of
changing and cleaning the air filter and
access to the fuse box. But one NSW owner
of a TJ375 said fuel tank access was poor.
Most owners (80%) were happy with the
location of the battery but one Queensland
owner of a TJ375 and one TJ450 owner also
from WA, rated it as poor due its difficult
access and poor attachment latch. Nearly all
owners (87%) praised the large toolbox.
