In the case of tractors, 4×4 and 4wd are the same, as 4wd tractors have 4-wheel drive and all 4 wheels receive the power. On the other hand, 4×4 also means the same; all 4 wheels will receive the power. (i.e., 4×4). In short, 4×4 and 4wd are the same in the case of tractors, and both denote that the power is received in all 4 wheels of the tractor. 4wd or 4x4 design enhances the tractor's ability to manoeuvre through challenging terrain, for example, wet and muddy farming land, pull heavy weights, and perform various tasks on farms, construction sites, and other outdoor settings.
