Ickleton is a beautiful little village that takes its name from the Icknield Way, the trading path from East Anglia to southwest England that passes through the area. This cache is located just off the main path that leads northwards from the village across the fields to Duxford.
At a crossroads in the path head west to the edge of the field to find the coordinates, and the old piece of farm machinery that gives the cache its name. Furrow your brow, I'm sure you'll work it out
