AN excavator attachment that allows drill stem posts to be driven accurately through concrete aprons and hard surfaces has won the Innovator of the Year award at the Australian Lot Feeders’ Association annual conference in Dalby, Queensland.
The drill stem driver attachment was developed by the team at Hancock Agriculture’s Maydan Feedlot near Warwick.
Based on a jack-hammer attachment for an excavator rock breaker, the team lathed the attachment down so the end of it can fit in the drill stem. It stays within the pipe and holds it while the excavator rams it in.
Maydan Feedlot manager, Chris Rickert, said they came up with the idea after needing a quick and easy method to replace posts and bunk rails in the feedlot.
“We started off with a vibrator on the end of the excavator, but it wasn’t good enough.
“You see a lot of contract fencers with post basher attachments, but the problem is when you lose contact with the post you lose control,” he said.
“That is an issue if you want to keep everything in a true line and weld off it.
“Our attachment doesn’t lose contact with the drill stem which lets us move it about and keep it on line.”
Mr Rickert said they had been using the attachment for two years and found it took about one minute 20 seconds per post.
Runner-up in the Innovator of the Year awards was Garvan Park Feedlot, Rathscar, Victoria, for a liquid dispersion disk which is designed to better disperse liquid in a mixer and reduce mixing time.
