With the opening of the Humber Bridge in 1981 it was decided to close the Grimsby factory and concentrate the processing operation for both banks of the Humber, at the geographically well placed factory sight at Hessle.
Over the next few years the vining operation improved, firstly with the move into self-propelled viners, which were then subject to continued modifications and improvement.
This resulted in greater output, crop recovery and quality, this in turn meant the acreage grown and tonnage harvested could be increased without a further increase in groups.
In the early 90s there was a further increase in acreage and tonnage when Unilever decided the Hull factory should provide its Italian frozen food company with peas to achieve this there were now seven groups now including the North Lincs or Lime Group each with two harvesters operating and the supporting teams.
In 2000 in the interests of efficiency and costs the number of groups was reduced to 5 each with 3 harvesters.
