If you are trying to build a structure, such as a home, you might want to watch this video. You do not necessarily have to be a land clearing contractor to understand the content here. In this video, there is a Bobcat S250, although you might be able to use different machinery if you are going to be doing some land clearing.
However, this is a very good choice, and it is a handy piece of equipment. In the video, there are multiple attachments, including a tooth bucket, a smooth bucket, a set of pallet forks, a post-hole logger with different-sized bits, and more. If you are not able to buy one, you can likely rent one for a reasonable price. In addition to this, it would be a good idea to have a small chainsaw as well.
In the video, it is highly recommended that you handle the project on your own with all of the equipment that is recommended, rather than trying to hire someone and ultimately spend a lot more money. Of course, you want to make sure that you are able to do all of this safely, as safety always comes first. If you are able to do so, however, it might be a good idea.
