The closing spiked wheels have been modified from US versions and we have perfected these in-house to give the best slot closure possible. We tried running the drill without these, but germination was much slower and the blackgrass got a head start. The depth wheel next to the disc is spoked so it doesn’t bung in wet conditions and is fitted with RID (reduced inside diameter) tapered tyres to avoid compacting the side of the seed trench.Ī custom slim rubber wheel forces the seed down into the soil and gives decent seed contact. The front discs are at an 11deg angle, with seed and fert coming down one pipe from the two hoppers via separate metering units so we can apply two products at different rates. Steve Heard says modification of the drill is an ongoing process How does it work? We seem to keep finding ways to modify it – most recently we added the spoked wheels and a little scraper to prevent the wheels clogging in wet ground. In the end, I had to fit a couple of rams and nitrogen accumulators that transfer the weight on to the drilling rig once the coulter bar is unfolded. The other issue was that the Americans run the coulter bar as a trailed unit and I wanted the 6,000kg hoppers to sit on top to provide extra downforce. It wasn’t an easy job, as the original drill was 5m wide folded and had different row spacings.

We shipped it over from the States, before I dismantled and rebuilt it to fit within UK road limits and with a working width of 9m. However, it has the same coulter assembly as the 750A, which has been in the UK (at a maximum width of 6m) for quite a while. Our drill is custom-built, 9m wide and based on an American-spec John Deere 1890.
