Checking and Adjusting the Blade Level Measuring Blade Level 1. On products with inflatable tires, check the tire pressure. Tires are commonly over inflated for initial shipment. Make certain that the pressure has been lowered to the correct level for operation and that the tires are very close to the same (see the Operator's Manual). If the range is 10-15 psi, do not have some tires at 10 psi and others at 15 psi. Keep them near the same pressure. Note: some products may have different recommended pressure for the front tires and the rear tires. Always check the Operator's Manual for the correct pressure. 2. Make a simple sketch of the mower housing to use for recording measurements. Show the outline of the mower and the blade(s). Leave a space to write in your measurements. Each blade must be measured at the 12, 3, 6, and 9 o'clock positions (Figure 14 and Figure 15). 3. If the desired height of cut is known, make your measurements at this setting. If this is not known set the mower in the middle of its height of cut (HOC) range. 4. VERY IMPORTANT: When you take the measurements, rotate the blade and use the SAME blade tip for measuring. Mark the blade with a piece of tape. It is not uncommon for there to be a slight difference between the two ends of the same blade. If you are working on a multiple blade mower, repeat the process with each blade. 5. If you are using the measuring tool (Figure 16), position the blade tip. Then place the tip of the tool under the tip of the blade and press the base of the tool on the floor. Read the measurement and note it on your sketch. Repeat in all 4 positions.
