33.5m (110ft) wide seeding rig
Gavin Zell and his father Bill, of Collarenebri in NSW, run an 18,200-hectare mixed cropping operation and have taken a novel approach to seeding by hooking two Flexi-Coil 820 cultivator bars together for increased capacity and reduced labour costs.

Gavin started hooking his Flexi-Coil ST820 bars together back in the early 90s. “We started off with the one ST820 bar and then decided to get a second one to match it so that we could hook the two together; giving us 33.5 metres (110 feet) of width to seed more land in one pass. The yellow frame linking the two 820 bars together was built by the late Barry Homan in Toowoomba and the whole rig is pulled using a Baldwin 600 tractor running triples.

Gavin Reports he added a floating link to run the bars side by side and can join them up or separate them within 15 minutes. Gavin says that the 2700 litres of fuel used to fill the Baldwin usually delivers 24 hours of operation covering around 486ha for a 24 hour shift including stops for filling with seed and fertiliser. This equates to 5.8 litres per hectare and an average speed of 6km/h

Surprisingly this is not that efficient for the effort required. 486ha in 24hr is only 20.25ha/hr. A 70' machine travelling at 10km/hr can achieve the same field efficiency with one aircart box to fill and with lower fuel consumption / ha. Bigger may not necessarily be better.

I think thats a good point - I think a focus on field efficiency should be maintained as we see gear getting increasingly larger with talk of for example 15m+ harvester fronts etc.
