First up I fed our four mobs of ewes. Then spent a few minutes cleaning up a few stones from and old wall that collapsed a few months back. Next up refuel the John Deere 4440 and a quick trip to town with it to unload a boom spray for the rural shop. It was supposed to be quick, but the truck was a few hours later that it was supposed to be, so not such a quick trip after all.
It was after all that that I thought I'd shorten the chains on the prickle chain.. they were a bit loose ya see. So there it is in the yard behind the 4440. The chains can be seen (this is in the folded position - usually they sit flat on the ground) and it easy to see why it's called a prickle chain. The chain does wear over time so it gets looser and looser. The solution is to cut out a few links, join it up and you're all set to go.
Disconnecting the chain was the hardest bit. Those bolts hadn't been undone for a while, and they get pretty rough treatment running so close to the ground. The whole chain rolls as it is dragged over the ground, and the "prickles" do their job. So the bolts were quite tough to get undone, but once I undid it (there is one for each section of chain) I could just unhook the chain and cut out a couple of links with the angle grinder.
I'm still trying to undo the front section (the left side - the right side is visible too.
Cutting the links. I took two off each section of chain.
