If you look through our archives, you'll find lots of case histories of repairs and some restorations of Greenfields. For the job you've described, they seem very suitable, though I would not recommend them for use with a dozer blade or for continuous operation at very low ground speeds, due to the slipping-clutch variable speed transmission they use. They last very well, and are usually quite repairable by a home mechanic even if you eventually wear something out.
