After the next rain, I will be using the aereator for which I bought the part referred to above. the part is an add=on for my John Deere zero-turn mower. I have to wait foer rain to soften the ground in that our sub-division is on a clay and field rock base. I have tried to remove all rocks I can see and sure to find more when I put the aereator to work using the hitch I ordered from247 Parts. As to the hitch, The directions are limited. The hitch bracket is one piece, almost. There are two brackets that muset firset be attached to the Mower--but do not remove the existing engine guard from mower. The drawing is a bit deceptive, so dread carefully. A previous rater said he had to remove the rear tires to permit installation. I agree on that, but it is not in the instructions. The notice as to the knives being sharp--heed that warning-- use old work gloves to put over each knife that is in the current work area as you move through the project. As per instructions--disconnect the ground (red) lead to the battery, but remember to reconnect the lead at the end of the installation. The directions drawing is not clear as to the (illustration) for hanging the pulling bracket--the bolt holes go up. But attach the hitch bracket onto the pull bracket before mounting the pull bracket to the mower. Once together, it is an awesome machine--but clay soil and many in-ground rocks are not your friends. A well engineered tool but read the instructions carefully.
