ᐅ Weeds and shrubs growing several feet high

Hello, I recently acquired a large plot of land (2500sqm (26910 sq ft)) that hasn’t been maintained for years. A hoarder used to live there, so there’s a lot of rubbish, a small old house, and plenty of wood. Now, grass and shrubs have grown wildly and are several meters high. I started clearing a small area by digging out the plants including their roots because I began building a wooden shelter. But when I think about doing this across the entire area... does anyone have a better idea?

Best regards, Ronny
