Fencing, Planting and Irrigation: Choosing the Right Digga Attachment

Earthmoving Attachments

Property improvement projects rarely stop at just one job. You might be replacing boundary fences, establishing shelter belts, planting trees, installing irrigation, or clearing old stumps to make way for new infrastructure. While each task has different requirements, the right attachment can make the work faster, easier and more efficient.

Whether you're managing a farm, acreage, lifestyle property or landscaping project, Digga offers a range of earthmoving attachments for DIY and professional projects, designed to tackle common digging, drilling and trenching jobs. From post hole digging and tree planting through to irrigation installation and site preparation, matching the attachment to the application can save significant time and effort.

Here's how to choose the right equipment for the job.

Part 1: Fencing

Every fence, whether it is a rural boundary, a garden privacy screen or a flagpole, starts with post holes. Digga has been designing and manufacturing post hole diggers in Australia for more than 40 years, with options for tractors, skid steers and excavators, including earthmoving attachments for DIY fencing jobs.

Pick the drive for your machine

  • Skid steers, excavators, mini loaders and tractors with loader arms: front-mounted auger drives with augers for all ground conditions. Digga says its drives are compact enough to go down the hole, which helps with deeper holes, and its Swing Control System dampens auger swing, so it is easier to shake dirt off and return to the hole.

  • Tractors, occasional drilling: a PTO-driven Ramdrill suits 50 and 75hp tractors and is aimed at farmers who drill the odd post or tree hole.

  • Working alone: Digga also makes a one-man post hole borer.

Pick the auger for your soil

Use the right cutting head for the ground you have. Digga's A1 earth auger is a general-purpose option for soft earth and clay, and it is not suited to rock. For harder, fracturable ground, step up to a rock auger rather than forcing an earth auger through it.

Go deeper and finish faster

With auger extensions, Digga says you can drill post holes up to 4 m deep. Once the hole is drilled, you can swap the auger for a mixer bowl and mix concrete to set the posts, with no separate cement mixer to buy or hire.

Part 2: Planting and irrigation

Good planting and irrigation give young plants the best chance of being established. The right tools also make the job much quicker.

Tree planting augers

Digga's TP tree planting augers drill a smaller hole for the tap root, with a larger hole at the top for the root ball. The cutting system leaves rough hole walls rather than smooth, glazed ones, which gives the plant its best chance of establishing and helps prevent root binding. They suit trees and shrubs of all sizes, are designed for earth, and are not suited to rock.

Trenchers for irrigation

Planting is only half the job if the plants cannot be watered. Digga trenchers are made for irrigation, electrical and plumbing trenches. The Mini Bigfoot, for example, is listed for hydraulic flows of 38 to 90 L/min and machines from 500 kg to 1.5 tonnes, so it suits compact machines used on residential and landscaping jobs.

Clearing the site

If the planting area needs preparing first, Digga's stump grinders for skid steers turn stumps into wood chips, which can be handy for mulching.

Before you dig anything

Before You Dig Australia (BYDA, formerly Dial Before You Dig) is a free national service that gives you plans to show underground pipes and cables at your site. You can lodge a request online, through the app, or by phoning 1100. Plans often arrive within minutes, but allow up to two business days, and responses are valid for 28 days. Not every asset owner takes part, so stay careful when digging even with plans in hand. If you hit a service, you didn't know about, the repair bill can fall on you, so it is well worth the few minutes. Also check the rules in your state, since some require a BYDA enquiry before excavation beyond a set depth.
