Cereals 2018: Weaving makes 8.0m GD road friendly

Weaving had an 8.0m version of its GD no-till drill on display on its stand. Like other models it employs an angled disc coulter to lift a slice of soil and place seed underneath it.

Individual coulters are linked by hydraulic hoses with gas accumulators providing damping to enable the units to rise and fall on their parallelogram linkages as the drill passes over lumps and bumps. Depth control is handled by a simple pin-and-hole arrangement on each coulter carriage while downforce is adjusted with a slider set-up that alters the amount of weight the rear wheels carry.
