Further to my last – I did get the bill for the hoses, and it was double the bill for the steel. So the whole build came to NZ$3000, which was about NZ$2000 over budget, and more than I paid for the tractor complete with flail mower in the first place! (NZ$1 = US$0.82 at present.)
Never mind, the FEL has proved very useful and has saved my ageing back(and my wife's). And when I put my wife in the bucket she can trim the top of the hedge while kneeling down.
