Gosh, now wonder people are so bothered about others borrowing their stuff. Yours all sound so flash!
We have an old grey plastic one and a blue one that were being thrown away in a skip (hubby mended them), a green one that has had a puncture for years, and a extremely rusty metal one thatis over 25 years old and also has a puncture!
I put other as its a mixture of steel and lots of rust... but perfectly serviceable and I only use it for poo picking. I find a tub trug is all I need to muck out - 1 tubtrug out per day, gotta love my clean mare !!
Have a yellow one for which must be 8-10 years old, have just invested in a new Pink one, purely by price, (think they had them priced wrongly- this was the biggest one there, but at same price) I did query the price by the way....
So now yellow one will stay with the mucking out and Poo briquette making, and will use pink on for transporting hay and feed!
Mine is a rather boring galvanised metal variety - never occured to me to buy a nice, colourful plastic one. Mind you, it's so old I'm not sure colours were an option back then
