^^^^^ lightweight build is a problem with all new tractors, even 50+ hp. In many situations a letter series Jd or Farmall will out perform a newer, higher hp, 4wd. The old tractors made huge torque at very low rpm, add the weight of build, and they are unstoppable. We used them to pull wagons with 500 gallons of maple sap before pipelines brought the sap down to a collection tank. Working from December to April the trails would go from packed snow to knee deep mud. Getting stuck was pretty rare.
Down here, a heavy tractor will get you stuck. When it rains in the sandy part of the country, and becomes soaked and saturated, the sand is now "quick sand" for lack of a better description.
In the black gumbo part of the area, heavier gets stuck faster as well.
Some guys down here I know add weight to their tractors by filling the tires with water, or getting their tires foam filled. Both add LOTS of weight.
