Whether your clearing up, riddling soils, de-rooting ground an RSL landrake, landscape rake, rake bucket ,whatever you call them is a fantastic attachment to have.    All RSL rakes are made from high tensile steel.  Hardox is an option but not necessary unless you dealing with extremely abrasive materials.  A better option is to tip the rake  with replaceable wear tips.  You only need to catch a root or swing round and hit something to bend a tine so the minimum material thickness we use is 12mm, even on the smallest machines.  All our rakes are designed and manufactured here in Hertfordshire.  We can bespoke make on request
