Wheel loader AR 420
55.4 kW (74.3 HP)
0.9 — 1.6 m³
The powerful wheel loader for main construction trades or civil engineering and road building
The weycor AR 420 belongs to our performance class L and is particularly convincing for heavy work. Especially in the main construction trade, in gardening and landscaping, for municipal use as well as for civil engineering and road construction, the weycor wheel loader is a good choice. The AR 420 is more than the sum of its parts - it is passion in action.
In addition to a service weight of 5.3 t, an engine output of 55.4 kW (74.3 HP) and a bucket capacity of 0.9 to 1.3 m³, let yourself be convinced by many other details of the weycor AR 420.

Features and benefits
Powerful drive unit
A weycor wheel loader can be moved in three ways: in operating speed range from 0 to 6.5 km/h, in road speed range at up to 20 km/h or also in optional high speed at up to 40 km/h. Here, 1st and 2nd hydraulic gear as well as forward / reverse travel can be engaged under load. The switching between the forward / backward travel, speed ranges and off-position is done via the weycor joystick. The drive is operated by accelerator and separate inching pedal for best distribution of the hydraulic power for thrust and lifting forces.
In weycor wheel loaders, we use robust, low-maintenance articulated-swivel joints almost exclusively in conjunction with rigid axes. With an oscillation of ±12° in the rear carriage and an articulation angle of 40°, these provide outstanding cross-country mobility, protect the ground and offer extreme manoeuvrability. With their low centre of gravity, weycor wheel loaders have a high tilt stability even under extreme conditions.
Hydraulic quick-change attachment
The hydraulic quick-change attachment turns the wheel loader into an all-rounder and allows attachments to be changed in a few seconds. The proven weycor kinematics provide high breakout forces and excellent lifting heights. The upwardly tapered loader arm offers the best view of the attachment.
As the only manufacturer, our wheel loaders have a separate inching pedal as standard. This prevents the possibility of moving against the operating brake, in contrast to the combination of a brake/inch pedal. A generously proportioned inching range facilitates precise distribution of shearing and lifting forces. The result: less wear and lower fuel consumption.
State of the art kinematics
weycor Z-kinematics is characterised by high frictional forces and excellent lifting heights. The very good parallel guide provides the optimal prerequisites for using pallet forks. When the hoist is lowered with the shovel, the shovel returns automatically to the digging position. The boom that is tapered towards the top provides the best possible view of the attachment and working area at all times, even under difficult operating conditions.
The spring-loaded or negative brake in weycor wheel loaders is a closed brake system (oil bath multipledisc brake) which holds the wheel loader securely in position on a slope when the brake or inch function is activated and automatically locks all four wheels when the engine is at a standstill. The multiple-disc brake runs in the oil bath and is particularly low-maintenance and low-wearing as a result.
In addition to the excellent circumferential visibility in the wheel loader, its clearly arranged controls and its ergonomic design.
Low-maintenance and quick, easy servicing is achieved by central, consolidated, easy-to-reach service points.
