Making Adjustments Attachments/Accessories Adjusting the Bedknife to the Reel A selection of Toro-approved attachments and accessories is available for use with the machine to enhance and expand its capabilities.
Note: If excessive reel drag occurs either backlap or grind the cutting unit to achieve the sharp edges needed for precision cutting. adjustments easier. Insert the 0.05 mm (0.002 inch) shim between the marked reel blade and the bedknife at the point where the blade crosses the bedknife. 4. Turn the right bedbar adjuster clockwise until you feel light pressure (i.e. drag) on the shim, then back off the bedbar adjuster two clicks and remove the shim. Adjusting the Rear Roller 1.

Side-plate mounting cap screws Rear Spacers The number of rear spacers determines the aggressiveness of cut for the cutting unit. For a given height of cut, adding spacers, below the side plate mounting flange, increases the aggressiveness of the cutting unit. All cutting units on a given machine must be set to the same aggressiveness of cut (Number of rear spacers, part no.

To adjust the height of cut when fixed plate kits are installed on the cutting units, proceed as follows: • Remove the height-of-cut brackets and the front roller as described in Procedure 5 in the Setup section. • Install the cutting unit onto the traction unit as described in the traction unit Operator's Manual.
Checking and Adjusting the Cutting Unit The dual-knob bedknife-to-reel adjustment system incorporated in this cutting unit simplifies the adjustment procedure needed to deliver optimum mowing performance. The precise adjustment possible with the dual-knob/bedbar design gives the necessary control to provide a continual self-sharpening action—thus maintaining sharp cutting edges, ensuring good quality of cut, and greatly reducing the need for routine backlapping.
Maintenance 2. Using a rag or thickly padded glove, hold on to the reel blade and try to move the reel assembly side to side (Figure 24). Lubricating the Cutting Unit Each cutting unit has 6 grease fittings (Figure 22) that must be lubricated regularly with No. 2 lithium grease. The lubrication points are the front roller (2), the rear roller (2), and the reel bearing (2). Note: Lubricating the cutting units immediately after washing helps purge water out of the bearings and increases bearing life. 1.
Servicing the Bedknife The bedknife service limits are listed in the following chart. Important: Operating the cutting unit with the bedknife below the service limit may result in poor after-cut appearance and reduce the structural integrity of the bedknife for impacts.
