Reduced radius, bulk zero back Work in the tightest spaces

Small radius

The reduced radius design makes the machine more versatile and allows it to work in confined spaces. This allows the driver to focus on the task at hand. Indeed, he does not have to worry about possible damage to the rear of the machine or to worry about others obstacles on the construction site. On the 305E CR and 305.5E CR models, the part top of the machine remains within 140mm of the undercarriage.

No rear dimensions

New to the E-Series, the 303.5E CR and 304E CR models feature of a zero rear footprint design. On these models, the radius of the upper part of the machine never exceeds the width of the train bearing.

Undercarriage stability and longevity

Rubber Chain - The standard rubber chain allows you to work on multiple surfaces such as grass, pavements roads or stony ground without damaging the surface or the machine. Steel chain option - The steel chain is available as an option for difficult conditions such as demolition sites. The weight Additional steel chains generally provide better stability when excavating to the side of the machine. (Not available on the 304E CR.)

Rubber pads - Optional rubber pads can be attached to the steel chain to prevent damage asphalt surfaces and to minimize noise and vibration during travel. This option provides maximum overall stability.

 Optimize your productivity

Simple blade control with function free position The operation of the blade is controlled by slave controls located inside the cabin, for flexible proportional use. The standard free position function is activated by pushing the lever forward. Cleaning and backfilling are facilitated because the driver does not need to adjust the blade height when moving.

Excellent visibility on the blade

Visibility to the blade is excellent in all positions. It is possible to position the blade behind the operator, far from the wheelhouse front in order to obtain better access during backhoeing work and finishing in tight spaces. Adjustable blade option Increase the versatility of your machine with the dozer blade orientable Cat. Designed for strength and durability, the blade hydraulic swivel has a hardened steel wear edge and provides good protection for cylinders and hydraulic lines. The swivel blade can be positioned in a straight line or oriented towards the left or right at an angle of up to 25 degrees. This reduces the number of times the driver has to back up and reposition the machine during backfilling operations, which allows it to finish the job faster. All blade functions are controlled using a manipulator equipped with a control orientation with proportional roller.
