s (2WTs) and very low center of gravity articulated steering 4-wheel tractors. Their designs by various European manufacturers were initially quite simple but effective, allowing them to cross slopes approaching 20%. In the 2000s new designs of wheels and tires, tracks, etc, and incorporation of electronics for better and safer control, allowed these machines to operate on slopes greater than 20% with various implements such as reaper-harvesters, rakes, balers, and transport trailers.
In Asian sub-tropical countries, a similar process has begun with the introduction of smaller, lower-tech and much lower-priced 2WTs in the 4-9 horsepower range that can be safely operated in the small, narrow terraces, and are light enough to be lifted and lowered from one terrace to the next. What is different from the Alpine use is that these 2WTs are being used for tillage and crop establishment of
