Remove trees by gradually pushing them over with the blade. Large trees may require a series of pushes to knock them down.
Attach chains around any remaining tree stumps or large boulders, and then attach the chains to the back of the bulldozer. Drive the bulldozer forward with the chains attached to uproot the tree stumps and boulders. Use the chains to pull down small farm structures that are structurally deficient or unneeded.
Use the blade to push rocks and other debris into piles for later pickup and disposal. Separate and sort the pile into manageable portions to avoid any extra work during the disposal process.
Level and grade the dirt with the bulldozer blade to prepare the land for farming. Keep the blade as low to the ground as possible without going into the ground. Attach a rake attachment to the bottom end of the bulldozer blade to pull away and clear any remaining debris.
