Thanks guys, had a go at a few things overtime in the shed, built a field bin when I was much younger wet my appetite for it I think, since then chaser bins, Ute trays,comb trailers, planter frames, sheds, this year's project was a one yr ol9m john Deere 1890 I bought down south and stretched to 12m to allow a transport width under 4.5m so easy to move around,as opposed to the near 6m standard jd 12m frame which requires multiple escorts etc, and then bought a new pull mount simplicity air cart and set it up as a trailing rear cart with a steerable front axle, and made it adjustable so can be easily changed from 2m to 3m
