Doherty Engineered Attachments have developed a range of Spade buckets for use in precision trenching operations. They are also ideal for use with sticky materials which tend to build up in a conventional bucket shell.
A feature of the Spade range is the ability to fit wider inserts to the base Spade Frame which is normally the narrowest width available. This means that there is no need to go to the expense of purchasing a complete new spade to dig a wider trench – just buy the appropriate insert which quickly bolts onto the base unit.
In order to keep the changeover process as simple as possible Doherty’s have designed a simple two bolt attachment on the protected back side of the insert. Other brands typically use a bolt through the cutting edge but these are prone to damage making changeovers slow and frustrating.
