These are "rowcrop" tractors, designed to be able to handle "cultivating" duties. The idea is to have the wheels as CLOSE together as possible so that they will go between rows of crops as narrow as where the rear wheels will go. There ARE tractors with just ONE front wheel, but that way generally the "footprint" is so small that the weight of the tractor makes the front tire sink into the ground a bit too deep, causing VERY difficult steering.

You are right, but it's because most modern tractors are not "rowcrop" type tractors. They do not have the "narrow front", so there is no reason to slant the wheels.
The "tricycle" or "rowcrop" front end allows the tractor to make a
180 degree turn in a space no greater than twice its width. This is
very handy for going up and down the rows of crops and for making square
corners when mowing. The drawback is that the tractor can be unstable
on hilly ground and can easily tip over if one rear wheel goes into a
ditch. A four-wheel tractor avoids this problem.
