How to Choose the Right Excavator for Farming?

Hello, I’m Sarah, a first-time farm owner. I’ve recently purchased a piece of land that requires some heavy clearing work. I understand that an excavator might be the right tool for this job but I’m unsure about which type or size to choose. Considering the different types of excavators and their capabilities, I’m seeking advice on how to choose the right excavator for farming. Can anyone with experience in this field guide me? I’d appreciate any input. Thanks in advance!
