Need a compact loader to get big results?

Choose the 304J. This versatile 73-hp machine

combines outstanding maneuverability, travel

speed, breakout force, reach, and stability in an

innovative package. Its oscillating stereo steering

delivers a turning radius that’s 20-percent tighter

than comparable loaders for fast work cycles.

Delivers smooth moves and better material

retention over rough terrain, too. Add to that a

redesigned, more spacious cab, and extra uptime

from sealed electrical connections, more durable

axles, and extended service intervals, and you’ve

got a multi-purpose machine that’s ready, able,

and willing to take on your many tasks.

304J Loader key specifications

Operating Weight.....................................13,404 lb.

Net Horsepower.......................................73 hp

Full Turn Tip Load....................................9,315 lb.

Bucket Size..............................................1.4 cu. yd.

Bucket Breakout Force...........................12,364 lb.

Unique stereo steering makes this compact loader
even more productive, for tight turns and extra agility
in close quarters.

Comes with standard items others call options —
return to dig, quick-coupler, high travel-speed range,
and 1.4-cubic-yard bucket.

Extended service intervals help maximize uptime.

100-percent manual differential lock helps you dig
down deep for more power.

Tier 3 emissions-certified five-cylinder turbocharged
John Deere diesel delivers power without compromise.

Unlike comparable-size machines, return-to-dig
is standard on the 304J.

Oscillating stereo steering combines machine
articulation and rear-axle steering, giving the
304J the tightest turn radius in its class.

Twenty-inch tires are standard.

1. Boom float allows easy backdragging for
finish grading and cleaning up jobsites.

2. The 304J’s unique design turns tight but
articulates less, keeping the center of
gravity and ballast in line to counteract
load forces — for superior full-turn
tipping load capacity.

3. An oscillating rear axle and elastic
articulation at the pivot smoothes the
ride for greater material retention and

2

reduced operator fatigue.

4. 304J’s long reach lets it easily dump
to the center of tandem-axle trucks
for quicker and easier loading.

5. Manual low-speed differential
lock delivers the traction needed
to go deeper into the pile for bigger
bucket loads.

When the going gets rough, get your

hands on a 304J and get going. Unlike

other machines that are frequently

forced into three-point turns (or worse), this

nimble loader’s stereo steering allows a

tight 148-inch turn radius for unsurpassed

maneuverability. Delivers higher tipping

load capacities, too. What’s more, the

PAGES

hydrostatic drivetrain’s infinitely variable

range lets you precisely match travel speed

to the work at hand. So you can inch ahead

while maintaining full hydraulic power.

Or max out at a fastest-in-class 19 mph. The

304J lets you move more materials, more

quickly, and more efficiently. Without running

you ragged.

When operation is easy, maximum pro-

ductivity becomes second nature. The 304J’s

sound-suppressed spacious cab provides

ample leg- and headroom, best-in-class

all-around visibility, and one smooth ride.

A single lever with FNR switch controls

all boom and bucket functions, and standard

return-to-dig is just a flick-of-the-wrist

away. Gauges in the forward console are

clearly visible, intuitive, and easy to read.

Tilt steering, multi-adjustable high-back

suspension seat, electronic monitor, and

many more productivity-boosting features

also are standard.

Inching/brake pedal lets you slow travel speed while keeping
engine rpm high for optimum hydraulic response and control.

Interior and exterior convex mirrors further enhance the
304J’s best-in-class visibility.

Add a highly efficient HVAC system and make your operator
even more productive. Automotive-type louvers help keep
the view clear, the cab comfortable.

1. Walk-through cab lets you enter or
exit easily from either side.

2. Boom and bucket control, FNR, and
differential lock are on the same
low-effort lever for convenient single­handed control.

3. Easy-to-read monitor tracks rpm,
time, hours, engine oil pressure,
and more. Issues both visible
and audible warnings.

4. Low- and high-speed ranges provide
infinitely variable travel speeds from
standstill to a best-in-class 19 mph.

5. Oscillating axle/elastic articulation
reduces cab tilt by as much as 50
percent for a smoother ride that’s
easier on both machine and operator.

Wet-disc brakes in the heavy-duty axles self-adjust
and are sealed from moisture and contaminants for
long, trouble-free life.

Proportional fan runs only as needed to provide
optimal cooling — for reduced wear-and-tear
on cooling components, reduced noise, and lower
fuel consumption.

Turbocharged Deere PowerTech™diesel runs
quiet and meets EPA Tier 3 non-road emissions
regulations. So it can work where rigid sound­and air-quality regulations exist.

Remote test ports enable technicians to quickly
troubleshoot problems.

1. Steering linkage is positioned where it’s
protected, and supported by brackets
with easily replaceable wear strips.

2. Angled self-cleaning steps and
ergonomically positioned grab
bars make getting in and out of
the cab easier.

3. A/C condenser tilts out and away
from the radiator for easier clean­out. Doesn’t require draining fluids

The hard-working 304J limits downtime with

its toughness and improves your bottom line

with its long-term reliability. Incorporating

many of the same features found on our larger

loaders, it’s built to keep downtime down with

sealed electrical connectors, flat-face O-ring

seal hydraulic couplings, and self-adjusting

wet-disc brakes. The 304J helps keep your

operator out of harm’s way, too, with numerous

safety features such as an automatic park brake,

bypass-start protection, slip-resistant steps,

and convenient handholds. If it’s uptime you

demand, the 304J provides all you and your

operator need to stay productive.

Why invest in a bunch of specialized

machines when the highly versatile 304J

can do the job? With its standard pin-type

hydraulic quick-coupler, the 304J lets you

go from bucket to forks, quickly and easily.

Or opt for the Worksite Pro

coupler that enables this jack-of-all-trades

™

skid-steer-style

machine to utilize an even wider array of

skid-steer-compatible Worksite Pro attach-

ments. Operation is easy, with joystick and

third- and fourth-function pilot controls con-

veniently located at your fingertips. Regardless

of how you equip it, the 304J will be the most

versatile compact machine on your worksite.

This guide, representing bucket sizes not necessarily manufactured by
Deere, will help you in selecting proper bucket size for material density,
loader configuration, and operating conditions. Optimum bucket size
is determined after adding or subtracting all tipping load changes due
to optional equipment. The “conservative load” line on this guide is
recommended when operating in conditions such as soft ground and
unlevel surfaces. The “maximum load” condition on this guide is
sometimes utilized when operating on firm ground and level surfaces.

CONTROL OWNING AND OPERATING COSTS

Customer Personal Service (CPS) is part of John Deere’s proactive, fix-before-fail strat­egy on machine maintenance that will help control costs, increase profits, and reduce
stress. Included in this comprehensive lineup of ongoing programs and services are:
Fluid analysis program – tells you what’s going on inside all of your machine’s
major components so you’ll know if there’s a problem before you see a decline in
performance. Fluid analysis is included in most extended coverage and preventive­maintenance agreements.
Component life-cycle data – gives you vital information on the projected life
span of components and lets you make informed decisions on machine maintenance
by telling you approximately how many hours of use you can expect from an engine,
transmission, or hydraulic pump. This information can be used to preempt catastrophic
downtime by servicing major components at about 80 percent of their life cycle.
Preventive Maintenance (PM) agreements – give you a fixed cost for maintain-
ing a machine for a given period of time. They also help you avoid downtime by ensur-

Specifications and design subject to change without notice. Wherever applicable, specifications are in accordance with SAE
standards. Except where otherwise noted, these specifications are based on a unit with all standard equipment, 405/70R20 tires,
ROPS cab, full fuel tank, and 175-lb. (79 kg) operator.

ing that critical maintenance work gets done right and on schedule. On-site preventive
maintenance service performed where and when you need it helps protect you from
the expense of catastrophic failures and lets you avoid waste-disposal hassles.
Extended coverage – gives you a fixed cost for machine repairs for a given
period of time so you can effectively manage costs. Whether you work in a severe­service setting or just want to spread the risk of doing business, this is a great way
to custom-fit coverage for your operation. And an extended coverage contract also
travels well because it’s backed by John Deere and is honored by all Deere construc­tion dealers.
Customer Support Advisors (CSAs) – Deere believes the CSA program lends
a personal quality to Customer Personal Service (CPS). Certified CSAs have the knowl­edge and skills for helping make important decisions on machine maintenance and
repair. Their mission is to help you implement a plan that’s right for your business
and take the burden of machine maintenance off your shoulders.
