There is always more than one way to skin a cat.
This one takes a little more hydraulics but does a good job for me.
Requires about 5 or 6 gpm flow & duel remote hydraulics besides the front loader.
Local lawnmore store gave me a discarded 30" riding mower. Took the deck off, swung it on some compressed springs, built a hinge so could point it any direction in 45 degree settings. bought a hydraulic motor & some hoses & came up with this.Mows under fences, on top of hedges. Lift it above a 1" or less, 8' tall tree and let the loader down. You have a few chips on the ground when the loader reaches bottom. Nothing to pick up.
Turn it sideways & push back the brush.
