The 3-point back blade, also known as a rear blade or angle blade, is an incredibly versatile attachment for tractors. It’s a seemingly simple piece of equipment, but its applications are surprisingly broad. Farmers, landscapers, construction workers, and even homeowners with acreage find it invaluable for a variety of tasks. Understanding its capabilities is key to appreciating its utility.
Grasping the Basics: How a 3-Point Back Blade Works
At its core, a 3-point back blade is a heavy-duty steel blade mounted on a frame that attaches to a tractor’s 3-point hitch. This hitch provides three points of connection – two lower lift arms and a single top link – which allows the operator to raise, lower, and tilt the blade. The blade itself is usually curved or slightly angled to facilitate the movement of material.
The magic lies in the adjustments. Most blades can be angled to either side, allowing you to push material to the left or right. Some also have an offset feature, which moves the blade further to one side of the tractor. This is particularly useful for reaching areas that are difficult to access directly. Finally, the blade can often be tilted vertically, allowing you to create drainage ditches or level uneven surfaces. These adjustments, combined with the tractor’s power, make the back blade a powerful tool for manipulating earth, gravel, snow, and other materials.
