[member=194324]PipKelpy[/member] I too, have a favourite wheelbarrow. Everybody else HATES it though! When it needed a new tyre I splashed out on a new wheel with a needle roller bearing, and the difference is amazing - it's just so easy to get going now.

SIMPLES.
OK, I'm stupid, but I'm not THAT stupid!
The latest bucket got cracked because I put it on top of a tall strainer post whilst I emptied rainwater out of the troughs. One Z stood on top of another Z's shoulders to get to it and knocked the bucket to the ground. They've never tried that before!
But you can manage to get a scoop between them and thus a small amount of food into the trough
Oh for the days when we only had five sheep that actually had a thing called a 'scare radius', but yes that's pretty much what I do. However, you missed the part about keeping your feet and knees together to avoid being hoisted off the ground and dumped in the mud (that's how the previous previous bucket got cracked).
Apologies if I appear to have misjudged you Womble. I have great admiration for your inventive powers, but you said yourself you are a serial abuser of buckets, and I have to agree.
To be honest you don't seem to engage your powers of reason to their full ability when dealing with sheep, as you do when dealing with an engineering problem. ( I really like the new wheelbarrow wheel. Could you add a link to it?)
I thought the 5 Zwartbles' heads in the bucket was your main problem, but now realise that it's only part of it. You have to always bear in mind that unlike machines - sheep are unpredictable. If it's possible to do something detrimental to you or to them or to their bucket then they will do it. The fact that they have never done it
yet is no guarantee that they won't do it next, so you have to be one step ahead.
Of course they will go between your legs if you allow room for their head, and carry you of to the next patch of mud. But surely that only happens once? And after that you keep your legs together sufficiently to prevent a rematch.
