The 1890 started out as a 9m machine, I bought it one year old, it was near new and in perfect condition, had to truck it about 700km but it was a little over half new price, and id left it to late to order a new one from the factory and have it delivered to Australia, so this was next best. I cut and stretched the wings to 12m, the main idea of this was to get a transport width of under 4.5m, stardard jd 12m folded with is closer to 6m, but over here under 4.5 means we only need one pilot vehicle to move it on public roads, and as I'm now a one man operation I can usually find one person to help me for an hr shift to my next job rather than two people, thankfully my wife is willing to do this most times.
The aircart is a 2014 simplicity unit, it was purchased as what they call a 'pull mount' ie would normally be mounted on the A frame of a drawn implement, this saved me considerable amounts and let me build a undercarriage for it with adjustable wheel track from 2m to 3m should our clients go down the 12m tramtracking path in time to come, I won't need to update cart I can adjust wheel track instead, I've made it with a steerable front axle, as in time it can be unhooked off this rig and hooked onto a 3pl fertilizer bar which we use a little from time to time, and having the front axle steer makes reversing the cart at the end of irrigation fields much easier
