Cutting Unit Safety Blade Safety • The cutting unit is only a complete machine when A worn or damaged blade can break, and a piece of the blade could be thrown toward you or bystanders, resulting in serious personal injury or death. installed on a traction unit. Read the traction unit Operator’s Manual carefully for complete instructions on the safe use of the machine. • Inspect the blade periodically for wear or damage.
Setup Media and Additional Parts Description Use Qty. Ball stud 2 Mount this to the roller. Operator's Manual 1 Read before installing and operating the cutting unit. Installing the Roller The cutting unit is shipped without a front roller. Obtain a roller from your authorized Toro distributor and install it on the cutting unit, as follows: 1. Remove the plow bolt and flange locknut securing one of the height-of-cut arms to the cutting unit side plate (Figure 3). 7.
Installing the Hoop Link, Offset Link, or Chain Link For cutting units mounting on a traction unit with a serial number prior to 240000001, obtain and install the proper lift link as follows: Note: The 2 bolts used to mount the lift link are shipped installed on the cutting unit. • For Greensmaster 3120 and 3150 traction units, install the hoop link supplied with the traction unit. Install the hoop link to the top of the cutting unit with 2 bolts.
Repositioning the Counter Weights The cutting units are shipped with the counter weight mounted to the left end and the motor mount to the right end of the cutting unit. To change the cutting unit to different positions, proceed as follows: Important: Whenever you need to tip the cutting unit on its side, ensure that you prop it up to avoid damaging the bedbar-adjusting bolts; refer to Supporting the Cutting Unit (page 13) 1.
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 8). 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 11), 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.

Spacer g000487 Figure 11 Note: If excessive contact/reel drag is evident, backlap, reface the front of the bedknife, or grind the cutting unit to achieve the sharp edges needed for precision cutting (Refer to the Toro Manual for Sharpening Reel and Rotary Mowers, Form No. 09168SL). 1. Raise the rear of the cutting unit and place a block under the bedknife. 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 Note: Determine the left and right sides of the machine from the normal operating position. Supporting the Cutting Unit Whenever you need to tip the cutting unit to expose the bedknife/reel, prop up the rear of the cutting unit to ensure that the nuts on the back end of the bedbar-adjusting bolts are not resting on the work surface (Figure 18). g278332 Figure 19 1. 30 degrees g016511 2. 1.3 mm (0.050 inch) Figure 18 1.
