Installing the Mower Preparing the Tractor Install the mower on a level concrete surface. Rougher dirt or lawn surfaces make installation more difficult. 6 1.
Attaching the Mower 1 1. Set the mower wheels for the lowest height of cut. 2. Move the attachment lift to the full up position. 3. From the right side of the tractor, slide the mower under the tractor. 4. Position the mower so that the slots in the side of each of the mower mounting brackets (Fig. 6) are aligned directly below the tractor attachment lift arm. 2 3 m–3456 Figure 7 Left Side of Tractor Shown 1.

Caution Components under the hood will be hot if the tractor has been running. If you touch hot components you may be burned. Allow the tractor to cool before performing maintenance or touching components under the hood. 2. Release the belt tension release arm on the pulley box housing and swing it out toward you (Fig. 10). 1 m–3521 2 Figure 8 1. Place hand here 9.

5. Hang the belt over the mower, then thread it forward through the belt guide (Fig. 12) on the mower. D. Swing the tension release arm into the pulley box and seat it by moving it into the position shown in Figure 10. 9. Loosen the belt guide bolt (Fig. 14). 2 2 3 4 1 m–3457 m–3465 Figure 12 1.

Measure the distance from the front tip of the blade (Fig. 16) to the flat surface. 5.
Adjusting the Side-to-Side Blade Cut 3 This optional adjustment is available if necessary to compensate for uneven side-to-side cut. 4 Equalize side-to-side cut by adjusting the two carriage bolts (Fig. 18) on the mower. Check the height of the blade at outside blade tips (Fig. 16). 2 5 1 6 1 m–3518 Figure 19 m–3459 Figure 18 Right Side of Tractor Shown 1. Side-to-side adjustment bolts 1. Indicator 2.

When the blade tip is in the front position, it should be approximately 1/4 in. (7 mm) lower than when it is in the rear position. 7. To adjust the blade slope, start the tractor, lower the attachment lift to take pressure off the cams, stop the engine, and remove the ignition key. 8. Loosen the cam nuts and equally rotate the left and right cams down to raise the front of the mower, or up to lower it. Tighten the nuts. 3 9. Repeat steps 4 through 8 until the slope of the blade is approximately 1/4 in.

Start the tractor and raise the attachment lift to provide ample clearance to slide out the mower. 13. Stop the engine and remove the ignition key. 14.
Operation Danger 3 Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with the rotating mower blades and thrown debris will cause injury or death. 4 • Never remove the grass deflector from the 1 mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. • Never put your hands or feet under the mower.
Bagging Mode You can also purchase various grass baggers and catchers from your Authorized Toro Dealer that you can install on your mower and tractor. A grass bagger/catcher catches the grass clippings, allowing you to remove them completely from your lawn. 1 m–3436 Adjusting the Front Wheels Figure 27 The two front adjustable wheels must be adjusted in the proper hole location each time you change the height-of-cut. 1. Rear transaxle cover 1.
• If you must stop while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously mowed area with the blades engaged and then raise the attachment to disperse the clippings evenly. • Keep the blade sharp. A sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding slows growth and increases the chance of disease. Every 30 days, check the blades for sharpness and file down any nicks.
1. Remove the mower; refer to Removing the Mower, page 11. 5 2. Carefully turn the mower over to expose the blades 4 Inspecting the Blades 3 1. Inspect the cutting edges (Fig. 28). 2 2. If the edges are not sharp or have nicks, remove the blades and sharpen them. 1 m–3585 3. Inspect the blades, especially the curved area (Fig. 28). Figure 29 1. Nut 2. Flat washer—thin 3. Blade 4. If you notice any damage, wear, or a slot forming in this area (Fig. 28), immediately install a new blade. 4.
Installing the Blades 1. Check the tension indicators on the front of the pulley box. If the tension indicators do not line up, release the belt tension and turn the adjustment knob. Push the belt tension release arm back toward the pulley box to tension the belt (Fig. 33). 1. Hold the blade end using a rag or thickly padded glove. 2. Install the thick washer, blade, thin flat washer, and the nut (Fig. 29).
Replacing the Blade Drive Belt 4. Lower the attachment lift, stop the engine, and remove the ignition key. Removing the Blade Drive Belt 5. Attach a hose coupling to the end of the washout fitting and turn water on high (Fig. 35). 1. Remove the mower; refer to Removing the Mower, page 11. Note: Spread petroleum jelly on the washout fitting o-ring to help the coupling slide on easier and protect the o-ring. 2. Remove the pulley cover mounting screws and pulley covers from the blade pulleys (Fig. 34).
Storage 1. Clean dirt and chaff from the top of the mower. 6. Check the condition of the blade drive belt. 2. Scrape heavy buildup of grass and dirt from the underside of the mower. 7. Check and tighten all bolts, nuts, and screws. Repair or replace any part that is damaged. 3. Use the wash out port to wash the underside of the mower; refer to Washing the Mower, page 18. 8. Paint all scratched or bare metal surfaces. Paint is available from you Authorized Service Dealer. 4.
