The two major problems with the existing roadside maintenance methods are:

Existing Roadside Vegetation Management

 

Vegetation remains around roadside reflector and traffic management posts after slashing is completed.

To manage vegetation, this results in either labour intensive manual removal or environmentally harsh chemicals being sprayed to curb regrowth.

Damaged or destroyed reflector posts

 

The existing slasher often damages or destroys roadside reflector posts, costing councils and other roadside authorities millions of dollars each year.

Other common issues that are a result of the current method are:

The existing rear mounted slasher increase WHS risk by the operator continually having to view the slasher operation at the rear of the tractor.  This also increases the risk of collision by the tractor while moving forward.

Poor cutting of the vegetation caused by the existing slasher technique which usually use a single slasher blade, which is not as efficient as a three bladed system.

There are additional hazards caused by tractor and slasher moving onto the carriageway in order to pass the guidepost.  There is no alternative if the operator is to try to cut as close as possible to the post.
