John Deere lawn tractors are durable and dependable. Lawn tractors help us perform our routine yard work as well as cutting the lawn. It is usually due to other yard work besides cutting grass, that the mower deck can become out of level. Once you know how to level a John Deere lawn tractor, you can mow with confidence. Unlike other lawn tractors, the John Deere will not require you to level the front and back separate from the side to side. Adjusting three different adjusting nuts will have your deck level and ready for use.
Park the John Deere lawn tractor on a level surface. Whenever possible park the tractor on the driveway or inside the garage. Use the operators handle to raise the mower deck to the highest position.
Lay the two 18-inch pieces of wood flat on the ground under the mower deck on each side. Place the boards so that they line up with the outside lip of the mower deck.
Lower the mower deck to the lowest position using the operators handle. The mower deck will now be sitting on the two pieces of wood. Ensure that the wood is not under the deck wheels.
Check the tension of the front draft arm. There should be no tension on the arm with the deck in the present position. If you have tension, loosen the nut on the front of the draft arm with a wrench until the front of the mower deck rests on the blocks. The draft arm is the arm coming from the front of the mower deck to the opposite side of the drive wheel pulley.
Slip the mower belt off of the front drive wheel pulley with your hands. Locate the leveling brackets and adjusting nuts at the rear of the mower deck. Look for the two arms that attach to brackets on the rear deck. The brackets that the arms attach to are the leveling brackets.
Loosen the leveling nuts on each side with a wrench and check that the bolts move freely in the bracket. Use the operators handle to raise the deck to the highest position and then lower the deck to the 1-inch mark on height mark beside the handle.
Apply slight pressure to the leveling bracket on one side of the mower and tighten the adjusting nut. Apply pressure to the opposite side bracket and tighten the adjusting nut. Turn the adjusting nut on the front draft arm until the front of the mower deck raise slightly off of the wood.
Lower the mower deck to the lowest position with the operators handle and slide the belt back over the drive wheel pulley. Raise the mower deck up to the highest position. Remove the boards from under the John Deere lawn tractor.
