EXCEPTIONAL COMFORT
The E series cab is isolation mounted for reduced noise and vibration, making it one of the quietest in the industry. Fully
adjustable steering column, suspension seat, and arm and wrist rests provide exceptional operator comfort. Floor to ceiling
glass improves visibility to the jobsite. Plus the 1221E wheel loader is among the quietest in the industry.
Superior comfort. Exceptional visibility.
EFFICIENT POWER
The 1221E is powered by an electronically-controlled, Euro III
compliant Cummins 11 litre engine. This fuel efficient motor
provides 320 net hp and strong torque from low revs, ensuring
maximum penetration into the pile and a high bucket fill factor,
boosting productivity and reducing ownership costs.
Maximum output. Reduced emissions.
ESSENTIAL MAINTENANCE
With fluid sight gauges on all reservoirs, all daily checks can be performed from ground level, increasing safety for the operator
and reducing downtime prior to work. Remote drains for the coolant, engine and hydraulic oil provide fast, convenient fluid
changes lowering the risk of environmental contamination. Remote grease fittings help make the machine’s daily maintenance
tasks easy. Extended service intervals and ease of maintenance result in lower ownership costs and improved productivity.
Easy access. Reduced downtime.
2
ENHANCED VISIBILITY
The cab’s large glass area, and the engine air pre-cleaner placed in line with exhaust stack ensure maximum visibility all around
the machine. Full height glazing to the front and sides of the cab provides an excellent view to the front wheels and the
attachment, increasing productivity and reducing operator effort.
Panoramic view. Increased safety.
ERGONOMIC CONTROL
An optional Ride Control system is available to reduce shock loading
and bounce in the loader arm. This results in a smoother ride for
the operator and increased load retention in the bucket. Ride Control
increases operating speed and reduces cycle times for intensive
load and carry operations. An auto mode engages Ride Control at
speeds over 9.5 km/h automatically when set, allowing the operator
to focus on driving the machine.
Load retention. Operator comfort.
EXTRA BREAKOUT
The 1221E is equipped with a robust Z-bar loader linkage design for maximum breakout force. An XR linkage is available for
higher dump clearance and increased reach. Powerful hydraulics deliver superior breakout and lift forces, reducing cycle times
and boosting productivity. Single loader controls incorporate transmission selection buttons for fingertip control of the machine.
High performance. Total control.

The 1221E is powered by a Tier III compliant 11 litre Cummins
engine, delivering a maximum output of 320 net hp (239kW).
Electronic control with high fuel injection pressures ensure
cleaner, more efficient burning, resulting in maximum output with
greatly reduced exhaust emissions and fuel consumption. The
machine is compatible with the Case electronic service tool (EST)
for rapid diagnostics and minimum downtime.
A torque sensing autoshift transmission, with a choice of manual
or fully automatic control, delivers the power to both drive axles.
Those axles both incorporate limited slip differentials, ensuring
maximum traction when digging and loading, which combined
with high torque at low revs provides an easy fill and high
penetration to the stockpile. The disc brakes are oil cooled for
maximum retardation and reduced heat build-up, prolonging
brake component life and reducing ownership and service costs.
The machine’s low effort loader control lever puts total control
at the operator’s finger tips, with a quick shuttle switch for rapid
directional changes.
As a leader in ergonomic design, all Case wheel loaders can be
specified with Ride Control, a system that allows the lift arms to
float while the machine is moving. Ride Control reduces shock
loadings in the machine, and the bounce that is felt in the cab,
reducing fatigue for the operator and prolonging component life.
Ride Control allows the operator to drive at higher speeds during
load and carry operations, improving load retention of material
and boosting productivity.
Selectable ride control settings include “always on”, “always off”,
or “automatic”, that automatically engages Ride Control when
the machine accelerates above 9.5 km/h.
OPERATOR’S CAB
The 1221E benefits from a roomy working space, the cab has a flat floor for ease of cleaning and full height glazing for maximum
visibility all around the machine. An adjustable, telescoping steering column and a fully adjustable operator’s seat ensure that any
operator can stay comfortable and fatigue-free through the working day.
Easy to read analog gauges and a digital display provide comprehensive information about machine settings and diagnostics.
The quiet, comfortable cab also includes a climate control system that provides exceptional heating and cooling on-demand.

Wide opening doors and pull down lower covers provide an
excellent level of service access. All daily check points, filters and
remote drain plugs can be easily reached from ground level,
making life easier for the service engineer and reducing downtime
for regular maintenance.
A hydraulically driven fan offers a reversing function to blow dust
and debris from the cooling pack in dry operating conditions.
All coolers can be easily accessed for cleaning and visual checks.
Centrally located greasing points provide easy access and bucket
pin seals prevent debris infiltration, prolonging component life.
The Case 1221E is fully compatible with the Case EST electronic
service tool system, providing rapid diagnostics and fault checking
to minimise downtime. All electronic components are centrally
located within the cab to ensure that they remain clean and out
of harm’s way.
Pillarless top to bottom glazing to the front and both sides of the
cab offers an excellent view of the bucket corners or attachment.
Powerful windscreen wipers keep the main window clear in all
weathers and the fenders prevent muck from the wheels being
thrown onto the windows.
Slim cab pillars provide high levels of visibility to the rear threequarters of the 1221E. This is essential for a wheeled loader
operator in a stocking and loading operation, promoting safety
in all operating conditions.
A rear windscreen wiper is standard, ensuring that the view to
the rear of the machine stays clear whatever the weather.
Optional rear view camera systems can be fitted to the machine
to further improve safety in mineral extraction operations.
The Case 1221E is equipped with robust Z-bar loader geometry
that allows high material retention and powerful digging forces.
For loading applications that require additional reach and dump
height an XR linkage is available that boosts reach and clearance
throughout the digging cycle.
In standard Z-bar configuration the machine offers a powerful
22,550 kg of breakout force, with an exceptional 31,690 kg lift
capacity, when equipped with a standard 5.7 m3 bucket.
