It leaves your lawn with a bagged look without bagging clippings. Mower is equipped with special parts which increase ability to cut and recut grass clippings, leaves, and otheryard debris into tiny particles which are injected down into the grass. TIPS FOR CUTTING GRASS. Follow these instructions for best cutting results and lawn appearance: 1. Always use FAST (full) throttle when mowing. 2. Maintain sharp blades throughout the cutting season. A sharp blade cuts cleanly and without tearing or shredding grass blades like a dull blade. Tearing and shredding causes grass to turn brown at edges which impairs growth and increases susceptibility to diseases. About every 30 days, remove wires from machine engine spark plugs and check cutter blade for sharpness. File down any nicks on blade to restore its sharp edge. 3. Clean any resudue from under side of mower deck and kickers after each use. If residure is allowed to build up in mower deck and on kickers, cutting performance may be unsatisfactory. A DANGER À Before removing any obstruction from mower deck, move PTO control into DISENGAGED position, shift into neutral and turn ignition key to OFF position. Remove wires from machine engine spark plugs to prevent possibility of accidentally starting engine. 4. When Recycler*mower is used to cut a lawn for the first time, remove about one inch or not more than one third of the grass blades. When cutting grass over six inches tall, cut twice to hide clippings down in grass. 5. If grass is ever allowed to grow slightly longer than normal, or if it contains a high degree of moisture, raise cutting height higherthan usual and cut grass at this setting. Next, cut grass again using a lower normal setting. This method of cutting long grass results in an even distribution of clippings and an acceptable quality-of-cut. 6. In heat of summer, it is best to cut only about one third of the grass blades. Cutting more than one third of grass off is not recommended unless grass is sparse or it is late fall when grass growth begins to slow down. Cutting grass down to thatch will reduce room to hide cut grass and will greatly increase amount of loose clippings. 7. lf cutting width of mower is widerthan a mower previously used, raise height-of-cut setting one notch to ensure undu- lations in turf are not cut too short. 8. Very long or extremely wet grass can be cut, using specific operating techniques. Start by setting height-of- cut in highest position. Using slow speed and maximum throttle speed, move mower into grass and cut a swath that is only half as wide as mower deck. Slow forward move- ment occasionally to allow mower deck to clear itself. Cutting too much grass may clog mower deck. If mower deck does clog, disengage PTO, move to cut grass, raise decktotransport position andengage PTO to clear mower. Lower deck and move slowly over clumps to disperse. MOWING IN EXTREME CONDITIONS Even with the Recycler®mower, you may encounter condi- tions where itis not possible to incorporate all grass clippings or leaves into grass. Air is required to cut and recut grass clippings in mower deck. It also takes extra power to recut excess clippings trapped under deck. Do not set height-of-cuttoo low ortotally surround mower deck by uncut grass afterinitial cut. Always try to have one side of mower deck free from uncut grass, allowing air to be drawn into mower deck. When making an initial cut thru center of uncut area, operate machine at a slower speed and back up if mower starts to clog. Under some unusual mowing conditions, mower may leave a “streak” of uncut grass, which can be caused by any of the following conditions: 1. Engine being operated at less than full throttle. 2. Dull blades or underside of mower deck clogged with matted grass. 3. Ground speed too high for conditions - adjust to 2 mph (3.2 kph), or less if necessary. 4. Streaking on turns indicates turns are being made too sharply. 5. If blades have been sharpened a number of times, they may now be too short to “overlap” each other, and must be replaced. STOPPING MACHINE WHEN MOWING It forward motion of machine has to be stopped while cutting, a clump of grass clippings may be deposited on lawn. Follow this procedure for stopping machine while cutting: 1. With blade engaged, move into a previously cut area. 2. Move throttle control lever to SLOW position, stop motion of machine, disengage PTO and rotate ignition key to OFF position. MOW AT PROPER INTERVALS Under most normal conditions you need to mow approxi- mately every 4-5 days. However, grass grows at different rates at differenttimes. This means that in order to maintain same height-of-cut, which is agood practice, yourneedto cut more frequently in early spring; as grass growth rate slows in mid summer, cut only every 8-10 days. If you are unable to mow for an extended period due to weather conditions or other reasons, mow first with height-of-cut at a higher level; then mow again 2-3 days later with a normal height setting. Alternate mowing direction. This helps dispense clippings over lawn for even fertilization, TIPS FOR CUTTING LEAVES In the fall, you can cut your leaves up into finely cut particles and inject particles down into grass. When spring arrives, leaf particles will have decomposed and restored valuable nutrients into soil. When cutting is complete, always be sure that 50% of lawn shows through finely cut leaf cover. This may require one or more passes over leaves. И there are more than five inches of leaves on lawn, raise mower one or two settings higher. This makes it easier to feed leaves under mower deck. If leaves are not cut up finely enough to be hidden down in grass, make a second pass 90° to first pass. MAINTENANCE AND STORAGE LUBRICATION Front belt pulley, spindle bearings and belt tension arm pivot should be lubricated at 50 operating hour intervals (Fig. 17 & 18). Use a pressure type brease gun and #2 multi- purpose lithium grease. Four to six pumps of a hand type grease gun will usually fill spindies after 50 hours use. Grease fittings are conve- niently located at top of spindle shafts. Lubricate mower gauge wheels every 25 hrs. Lubricate pivoting arms and levers at 25 hour intervals with light machine oil applied directly to wear surfaces. Anti- scalp rollers shouid NOT be lubricated. GREASE FITTING, __ ‘2048 BLADE MAINTENANCE A CAUTION À Sharp edges of mower blades can cut you during blade maintenance or adjustment. Use suitable covering over cutting edges of blade to prevent bodily harm. FIG. 17 Mower Lubrication Fittings To obtain optimum mowing results, mower blades should be kept sharp and well balanced. Tosharpen blades, remove mower from machine and invert mower. Remove blades using optional Toro ProLine spindle blade wrench. Hold spindle hex with wrench while removing blade attach- ing nuts and washers from end of spindles. If Spindle blade wrench is not available when servicing, a short piece of 2" x 4" lumber may be placed between side of mower deck and blade to “lock” it in position while removing attaching hard- ware. File or grind blades evenly. Take care to retain angle of original cutting edge. Blade balance can be checked on an inexpensive blade balancer, available at most hardware stores. Reinstall blades with lift area (turned up section) facing mower deck. Tighten blade attaching nuts to a torque of 80- 100 ft. Ibs. (112-140 Nm). Reinstall mower on machine. UNDERSIDE CLEANING It is of vital importance to clean underside of mower deck frequently. Accumulation of matted clippings seriously im- pairs mower's ability to “lift” grass blades into cutting position and discharge clippings evenly. Matted grass clogging underside of mower is often times a cause of uneven cutting. MOWER DRIVE BELT REPLACEMENT Remove drive belt by reversing procedures under "IN- STALL DRIVE BELT" section of this manual. Be sure to purchase genuine Toro ProLine belts for replacement purposes as these belts are designed specifi- cally for each application. Install new drive belt as oulinded under "INSTALL DRIVE BELT" section of this manual. SPINDLE BELT REPLACEMENT Remove mower from machine. Note routing of belt. Remove left and right belt covers. Checkto be sure all pulleys work freely. Install new Toro ProLine belt. Reinstall belt covers. Reinstall mower on machine. GENERAL CARE AND STORAGE Top of mower deck should be washed with a garden hose after each use. A mild automotive detergent may be used to remove stubborn dirt. After washing, allow mower to dry, Then start machine and engage mower for approximately one minute to remove excess water from belts and pulleys. Touch-up painted surfaces with a fresh coat of “Toro ProLine Red", available from your authorized Toro ProLine dealer in aerosol cans. Store mower in a clean, dry place or protect it with a weather-proof cover when stored outdoors.
