Product Overview Operation Specifications Refer to your traction unit Operator’s Manual for detailed operation instructions. Before using the cutting unit each day, adjust the bedknife; refer to Adjusting the Bedknife-to-Reel Contact (page 6). Test the quality of cut by cutting a test swath before using the cutting unit to ensure that the finished cut is correct.
B. Adjusting the Bedknife to the Reel Insert a long strip of cutting performance paper between the reel and bedknife, perpendicular to the bedknife (Figure 5), then slowly rotate the reel forward; it should cut the paper; if not, repeat steps A and B until it does. Use this procedure during initial cutting-unit setup and after grinding, backlapping, or disassembling the reel. This is not a daily adjustment. 1. Position the cutting unit on a flat, level work surface. 2.

Adjusting the Height-of-Cut Gauge Before adjusting the height of cut, set the height-of-cut gauge as follows: 1.
7. Verify that the height-of-cut setting is correct; repeat this procedure if necessary. Adjusting the Cut-Off Bar Adjust the cut-off bar to ensure that the clippings are cleanly discharged from the reel area, as follows: Note: The bar is adjustable to compensate for changes in turf conditions. Adjust the bar closer to the reel when the turf is extremely dry. By contrast, adjust the bar further away from the reel when the turf conditions are wet.
Maintenance Servicing the Bedbar Only a properly trained mechanic should service the bedbar and bedknife to prevent damage to the reel, bedbar, or bedknife. Ideally, take the cutting unit to your authorized Toro distributor for service. Refer to the Service Manual for your traction unit for complete instructions, special tools, and diagrams for servicing the bedknife.
Assembling the Bedbar 1. Install the bedbar, positioning the mounting ears between the washers and the bedbar-adjusting screw (Figure 13). 2. Secure the bedbar to each side plate with the bedbar bolts (nuts on bolts) and 3 washers (6 total). 3. Position a nylon washer on each side of the side-plate boss. Place a steel washer outside each of the nylon washers (Figure 15). 4. Torque the bedbar bolts to 27 to 36 N∙m (240 to 320 inch-lb). 5.
Bedknife Specifications Installing the Bedknife 1. Remove the rust, scale, and corrosion from the bedbar surface and apply a thin layer of oil to the bedbar surface. 2. Clean the screw threads. 3. Apply never-seize compound to the screws and install the bedknife to the bedbar. g255046 Figure 18 1. Bednife screw tool 3. Torque to 23 to 28 N∙m (200 to 250 in-lb). 2. Install and torque these first to 1 N∙m (10 in-lb). 6. Grind the bedknife. Preparing the Reel for Grinding g255045 Figure 17 1.
Bedknife Grinding Specifications Relief-Grinding the Reel The new reel has a land width of .8 to 1.2 mm (0.03 to 0.05 inches) and a 30° relief grind. When the land width gets larger than 3 mm (0.120 inch) wide, do the following: 1. Apply a 30° relief grind on all reel blades until the land width is .76 mm (0.030 inch) wide (Figure 19. g032182 Figure 20 1. Relief angle 4. Front face 2. Top face 5. Front angle 3.

Checking the Top Grind Angle Backlapping the Cutting Unit The angle that you use to grind your bedknives is very important. Use the angle indicator (Toro Part No. 131-6828) and the angle-indicator mount (Toro Part No. 131-6829) to check the angle that your grinder produces and then correct for any grinder inaccuracy. 1. Place the angle indicator on the bottom side of the bedknife as shown in Figure 21. DANGER Contact with the reel or other moving parts can result in personal injury.
