A tree trimming machine capable of moving between rows of grove trees to remove interior growth from the trees while leaving a canopy of tree boughs over the trimmed area includes a wheeled platform supporting right and left saw units positioned at the front, each having upper and lower circular saw blades rotatably carried by bearing members so the planes of all saw blades are parallel and held laterally beyond the sides of the platform. Slideways are fixed on both right and left sides of the platform, at an angle relative its mounting surface, along which the saw blade bearing members move between upper and lower limits to simultaneously raise and lower the saw blades that are hydraulically driven by a pump powered by an internal combustion motor mounted at the rear, which also drives the vehicle wheels.
