Just got back from seeing the new Team 24m spray boom with totally auto folding or gulling. A very impressive item. I have designed the auto folding and inhibitor circuit as an addition to the box we built last year.
The boom has two sections on each side and these can be folded individually to give 12m or the full 24m The new addition allows each side to be raised about 18 degrees so that it can spray a valley side whilst driving along the bottom. It is really impressive to see it at full angle up when set at 24m
The booms fold alongside the tractor so they must be completely folded when they arrive into the supports, so I designed a system that stopped the boom folding and automatically raised the boom to the correct position before going in to the folding sequence using only one switch.
I knew what the design would do in theory and when all the relays clicked in sequence on the bench I thought we were on the right lines, but it is something else to see it perform for the first time. I'm chuffed to blazes.
Its been a few days with ice packs on the head and then two or three late nights getting it together.Especially when the man who designed the boom is with you and says he never thought it would work like that!
I only had my normal cameras with me today so will post pictures when I get the film developed.
If anyone is going to the Cereal Event near Cambridge or the Royal Highland Show, they can see the beast in the flesh on the Team stand. Its a tractor mounted one on a John Deere.
