At this year’s Get Attached, Exac-One unveiled the bigger capacity Diga-Bara Xtra dumper trailer.

Bigger Diga-Bara

Nick Johnson reports on the new implements displayed at the Get Attached demonstration days staged by attachments supplier, Exac-One.

Twelve months ago, my visit to the annual Get Attached demonstration was marred by wet weather. This year, however, the sun shone on the event, which has gained a good reputation for revealing ever more interesting ways to profitably utilise a compact excavator. The display is organised by Andrew Harker and Doug Guest of Exac-One Ltd. They have trawled the world to put together a portfolio of different attachments, and they utilise the rural location of their premises in

Upton-upon-Severn in Worcestershire to stage realistic working demonstrations.

Exac-One is the sole UK source of the Diga-Bara that has been developed by Joe Carroll of Lancaster-based JC Engineering. This two-wheeled dumper trailer can be hitched to a coupling fitted onto the top of the middle of the dozer blade on a mini excavator. The excavator can then push or pull the dumper trailer and, as demonstrated at Get Attached, the combination is very manoeuvrable.

Hydraulically tipped skip

The established Diga-Baras have heaped capacities from around 500kg to 750kg and can be used with mini excavators weighing 1.0 to 2.5 tonne. The operator can load the skip and then propel the unit to the point where its load is to be emptied. These simple models have skips that are mechanically tipped by the operator from his cab, using the excavator’s bucket.

Now, however, there is a new, bigger capacity Diga-Bara that incorporates a hydraulically tipped skip. Literally completed just before the start of Get Attached, the ‘Xtra’ model has a skip that is 2.0m wide


by 1.8m long, providing a heaped capacity in the order of 4 tonne. It was demonstrated coupled up to the dozer blade of a 5.6 tonne Kubota KX057-4 mini. The dumper trailer’s tipping cylinder was plumbed into the excavator’s dozer lift circuit so that, once the blade was fully raised, hydraulic oil was diverted to tip the skip. The Xtra is piped for hydraulic brakes so that it can also be used with a compact tractor.

This RCM strimmer attachment from Italy allows a mini excavator to rapidly cut long grass on slopes.

Over the years, Exac-One has proved adept at sourcing some very interesting attachments to allow excavators to do much more than simply dig holes in the ground. The company’s latest finds are a strimmer attachment from Italy and an Austrian log/tree stump splitter. The former has been produced by RCM Srl to suit minis weighing over 1.5 tonne. For Get Attached it was fitted

onto the dipper arm of a 2.2 tonne class Kubota U20-3α mini. The strimmer’s hydraulic motor directly drives a well-guarded 480mm diameter cutting head. The demonstration strimmer head had 24 nylon cords arranged in six groups. These quickly cut through the long grass and vegetation on a steep bank in front of the Kubota. More cords can be fitted when required.

Also creating interest was the Lasco M2-4.0K log/tree stump splitter, demonstrated on a 4.0 tonne class Kubota KX121-3α mini fitted with an Easy-Hitch 5 quick hitch. This attachment is one of five models now available from Exac-One to suit excavators from 1.5 to 25 tonne. It has two high-torque Danfoss motors driving a cone-shaped cutter through a gearbox. The reversible cone is driven into a tree trunk to split it, and the attachment can be used to pick and place pieces of timber.
