RECYCLER® MOWER TIPS
RECYCLER®* MOWER FEATURES
Your Recycler®mower has a new and completely different
cutting concept. 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.

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.
