One day earlier this spring my son and I were planting trees. I had four shovels at the farm that day, and he broke two. I finally told him if he broke one more shovel, he was planting the rest of the trees by himself. Those words were magic, somehow inexplicably, strengthening the handles of our remaining shovels.
Wouldnāt that depend on how tall and how close the fulcrum was to the world? 
While Iām thinking of it. One handy tip I use to pull T-posts is a jack stand as a fulcrum. I take a small bit of 1/4" chain and wrap it around a lever (sometimes using another T-post laying around as a lever), then wrap the other end of the chain around the t-post fixed in the ground and push down on the lever with the fulcrum and the T-post will pop out of the ground. Sometimes Iāll use a log for a fulcrum, if I donāt have a jack stand handy.
Never pull a T-post out with your back, if you can help it. Good way to hurt your back. T-posts are always more determined to stay in the ground than you think, when pulling them out with your hands.
