So we are looking possibly for a well used small crawler as the drill tractor. We don’t want anything heavy like the current variety of crawlers so we are looking at Cat 55 or JD 10/20 series. We don’t need any more than 250hp maximum but 200 would be fine. The current drill tractor which is on wheels also has to be involved in root crop harvest so can’t be everywhere. Budget £40,000 top end. We have used both a cat 55 and JD 8520t years ago via a third party. The cat never missed a beat where as the JD had metal bits in the rear end oil twice needing rebuilds. However the JD was the nicer to operate. No road work involved.
