Optional dual row-crop wheels have been introduced for the Vervaet Quad 550 self-propelled slurry applicator by UK importer J Riley.
This new wheel option was first used in Europe last year but has now been made available to British customers as well. Two UK contractors are using the dual row-crops this season, and a third customer has specified slightly wider single wheels to work with various row widths.
The dual row-crop wheels are configured with a 75cm spacing that allows spreading to be carried out post-drilling and through young maize without causing damage to the crop. This allows an additional dose of digestate to be spread on the growing maize and extends the working season for contractors by an extra three to four weeks.
With a tank capacity of 22 cubic metres, the Quad is a large machine, but the dual-wheel format spreads its weight across a considerable area to minimise compaction and avoid creating ruts. Rather than fitting single row-crop wheels with add-on dual-wheels, the heavy-duty dual row-crops are welded solid, effectively creating a single wheel with a pan and rim on each side of a strong tubular centre section.
In common with the Quad’s conventional wheels, various tyre sizes and options are available, although the most popular tyre for the dual set-up so far is Michelin’s SprayBib VF 380/90R46.
“The Quad’s versatility is invaluable in allowing contractors and growers to prolong the spreading window and maximise their usage of digestate as a renewable and sustainable nutrient source,” the managing director of J Riley Beet Harvesters, Matt Carse, said. “The dual row-crops make it possible to apply digestate with minimal crop damage at a time of year when traditionally you couldn’t.
“Two contractors were operating with rear tankers, but have removed these while running on the dual row-crop tyres. The tankers will be reattached for working on stubble after harvest when maximum capacity is again the aim, making the Quad the most versatile and flexible machine on the market.”
