This One-man Post Hole Digger is designed to put the power of a two-man machine in the hands of one-man. The unique right-angle design minimizes operator fatigue by eliminating torque kick-back to the operator.

The One-Man Post Hole Digger is equipped with a centrifugal clutch and all operating controls are located on the handlebars for the operator's convenience.

PO BOXES : NO parcels above 22kg and/or longer than 1meter can be sent to a PO Box. Signature is required.

1. Goods are shipped once payment is received in full. We strongly advise all customers that they provide a delivery address where someone is available to sign for the goods during business hours. Sometimes, a forklift will be required to unload at the destination. If customers don’t have means to unload, you may be required to pick it up from a designated courier depot, OR pay an extra fee for the tailgate to unload the item when delivering to your nominated address. Please send us a message or call us (03) 9210 0400 to arrange.

2. All courier companies will attempt delivery of your goods once. If no one is home when delivery is being attempted, a note will be left. A re-delivery will incur extra charges. All second deliveries need to be directly organised with the courier company and paid for before goods are delivered.

3. Once in the hands of the couriers, freight times are outside of our control. However all tracking details are forwarded via email upon dispatch and customers are welcome to contact the relevant freight company, or we are happy to attend to any queries you may have.

4. FREE SHIPPING PROMOTION: This only applies to customers in capital cities. Free Shipping does not apply to regional areas.
