I have a post hole auger, you're all welcome to borrow it if you can work out how to attach it to the tractor.

It looks like attaching it becomes easier if you get you body position correct

Have you considered a hidden/electronic fence? They are very popular here in the US 'cos most people don't want fences around their gardens. I wished they'd been available in the UK when I lived there.

It's not only keeping our hounds in that is the problem, but keeping those on the acreage behind us out. I also suspect that our hounds are also a bit long in the tooth to be effectively trained for the electronic fence.

Neighbours on one side are going halves with us, the otherside has been asked but does not want to!
My husband had every intention in doing it himself as he is a Carpenter. But he is that busy with work and we want all the garden sorted for when my parents come over so we have got prices off people to do it so one less job for husband to do as lots for him to do inside the house too! It does not work out that much cheaper to do it yourself with the cost of all the wood.

We achieved 100% results with our Electronic perimeter fence containing 2 dogs. Easy installation and about $500 from Canadian tire, even cheaper now (on sale).
You dont even have to bury the wire. On our lawn boundary it is stapled and the lawn tractor wil never come into contact.

Imagine going to the expense of a fence that could still be defeated by your dog! As they will try!
