A skid is the way to go if your primary business is digging/construction. A tractor will do anything that a skid will, but it will take longer. A skid will not do everything a tractor will! One thing to keep in mind is quality tractor implements are much more affordable than skid attachments!You dont aerate athletic fields with a skid! This is a tough decision, look before you leap!
When i find myself in times of trouble, mother mary comes to me, speaking words of wisdom let it be.
