Root Rat - Complete Root Removal

About Us

Why we chose the Root Rat®

Having been involved in tree work for over 30 years and tried every method of stump removal from hand digging to stump grinding to heavy machinery, I have been asked many times to remove stumps completely.

This has become much more common lately with the development of brown field sites where new houses or buildings are built on areas where there have been mature trees.

Tree stumps needed to be completely removed to accommodate the buildings but this was not something we could do easily.

Our stump grinders could only remove the top 300mm of the stump leaving the majority of the roots in place. Digging them out was an option but leaves the problem of disposal of a heavy mass of rootball, not to mention the risk of damaging any services near the root during removal.

Remembering a tool I had seen on Tomorrows World (a BBC television programme running from 1965 – 2003) back in 1988, I went looking to see if still existed or if there was something similar.

This is how I came across the Root Rat®, a tool designed and manufactured in Germany.

Having seen it in operation, it overcomes many of the problems associated with other methods for stump removal in an efficient  and cost effective way.

Who came up with the idea?

Hartmut Neidlein (b. 1968) has been involved in arboriculture for about 25 years.

In 1993, he successfully completed one of the very first advanced training courses at the Academy for Horticulture (Lehr- und Versuchsanstalt für Gartenbau) in Heidelberg to become an agronomist for arboriculture and tree rehabilitation.

From 1993 to 2011, Mr. Neidlein managed an Arboricultural Company and since 1999 also ran an office of Arboricultural Consultants.

In 2008, Hartmut Neidlein developed Root Rat® and the first prototypes were produced.

His experience in tree root grubbing played a decisive role for this development.

Conventional root cutting techniques no longer satisfied him and his team.


The Root Rat® is available in 5 different sizes for excavators with a weight between 1 and 30 t.
