Yeah Dave, they make them way bigger and with way more horsepower since this tractor was made. Row crop tractors up to 400 horses and the articulators like the one in the previous thread are up to 600 HP and can be arranged for triple tires all the way around. You can also get track models. There is also a company that sells tracks to retro fit any tractor. Tracks displace more weight that helps with soil compaction which can cause plants to get root bound in tight soils. This can really hurt yield. The tracks help a lot in height traffic areas in the field. This is really Important for no till. The tracks also help the tractor get more traction for pulling.CF
