Elements of Great Quality of Cut Overview Quality of cut issues are best handled before they happen. Two factors largely determine quality of cut: proper mower setup and adequate operator instruction. This section describes the elements of proper mower setup. It also describes the elements mower preparation, lawn preparation, safety procedures, and mowing tips the operator should know to use the mower safely to get a great quality of cut.
Elements of Great Quality of Cut 11. Check the transmission fluid level. (See owner's Demonstrate for the operator the sound of the manual; some models have a sealed engine operating under a normal load and then transmission.) operating in an overloaded condition in which it is starting to bog down.

Inspecting and Sharpening the Blade Overview This section describes how to remove, inspect, sharpen, balance, and install a blade. Blade condition is a key factor in quality of cut. The blade should always be straight and sharp. A sharp blade produces a clean, neat cut and helps ensure healthy grass plants.
Inspecting and Sharpening the Blade Inspecting the Blade Sharpening the Blade Carefully examine the blade for sharpness and wear, File or grind the top of the blade to maintain it's original especially where the flat and curved parts meet cutting angle and inner cutting edge radius. To keep the blade balanced, remove the same amount of (Figure 5).
Inspecting and Sharpening the Blade Installing the Blade Blade Bolt (Nut) Torque Guide for Lawn-Boy, Toro, and Toro Wheel Horse Mowers built in 2002 Install the blade onto the spindle or blade driver. If the blade has curved tips (sails), they should be pointing towards the mower housing (Figure 9).

Checking and Adjusting the Blade Level If the desired height of cut is known, make your Measuring Blade Level measurements at this setting. If this is not known On products with inflatable tires, check the tire set the mower in the middle of its height of cut pressure.
Checking and Adjusting the Blade Level If you don't have the measuring tool, use a piece engine or spindle and the housing. Check for level after of wood just short enough to fit under the mower installing shims. housing. Wrap one end with tape. Place the untaped end on the floor and the tape against the cutting edge of the blade (Figure 17).

Checking and Adjusting the Blade Level Reinstall the pivot and wheel. When you reinstall the wheel, use the extra clearance to raise it to the position of the other front wheel. After reinstalling the wheel and pivot, verify that the blade is level side-to-side. Adjustinq Side-to-Side Level If the blade is not level within 1/8 inch (3.1mm) side to side, the engine will need to be shimmed.

Checking and Adjusting the Blade Level Adjusting Side-to-Side Level The blade should be level within 3/16 inch (5.0mm). The height of cut bracket on the left side of the chassis can be adjusted up and down to level the blade. Loosen the two cap screws holding the bracket to the frame rail to do this (Figure 32).

Checking and Adjusting the Blade Level Adjusting Side-to-Side LevelmAII Cutting Units Front Measure from the blade tip to the ground on each side. On single blade mowers use the same blade tip for both measurements (Figure 35). On multiple blade models, choose a tip on each blade and mark it so you can refer back to the same one (Figure 36 and Figure 37).
Checking and Adjusting the Blade Level Adjusting Front-to-Rear Pitch (16 ram) Each of the three XL cutting units has a slightly different specification for front-to-rear pitch and slight variations in the adjustment process. Each cutting unit is covered separately in one of the following subsections.

Checking and Adjusting the Blade Level 44-inch (111.7cm) Cuttin,q Unit To adjust the front-to-rear pitch, loosen the front pivot plate mounting bolts slightly (Figure 44). Check side-to-side level and adjust as needed (see "Adjusting Side-to-Side Level--All Cutting Units" on page 4-10). Measure the length of the rod extending out the front of the adjusting block on the sides of the chassis (Figure 45).
Checking and Adjusting the Blade Level Measure from the front blade tip to the ground, After adjusting both eyebolt lock nuts evenly, mark that tip with tape for future reference and check the front-to-rear pitch again. Continue rotate it 180 degrees to the rear and measure from adjusting the eyebolts until the front blade tip is the tip to the ground.
Checking and Adjusting the Blade Level 38- and 44-inch (96.5 and 111.7cm) Cuttin,q Units To check for a bent spindle, remove the belt and spin the blade spindle. Look at the center; if it rotates in a On mowers with multiple blades, not only do the blades tight circle, the spindle is not bent.
Checking and Adjusting the Blade Level 260 Series Tractor There are four mower attachments for the 260 series tractors. The process for adjusting the 38-inch (96.5cm) mower is different from that for adjusting the other mowers, and so it is described separately. The 42-, 48-, and 52-inch (106.6, 121.9, and 132.0cm) mowers all require the same leveling process, and so they are covered together.

Checking and Adjusting the Blade Level Adjusting Blade Tracking washers to shim the spindle housing, remove the bolt and reassemble through the washer to secure it. On mowers with multiple blades, not only do the blades need to be a minimum of 1/8 inch up from the bottom edge of the housing, but they must also line up where 5xi Series Tractors the tips come together.
Checking and Adjusting the Blade Level 60-inch (152.4cm) Mower Adjusting Transport Blade Pitch The mower blades should also be level side-to-side Because the attachment lift is used when the PTO drive within about 3/16 inch (4.76mm).

This usually refers to grass that is not cut at all, as opposed to grass cut longer than the mower's height of cut setting should leave.
