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 other yard 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 withouttearing 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.
4. When [email protected] 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 higher than 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. If cutting width of mower is wider than a mower
previously used, raise height-of-cut setting one notch to
ensure undulations 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
deck to transpont position and engage 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 con-
ditions where it is 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-cut too low or
totally surround mower deck by uncut grass after initial 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 shortto “overlap” each other, and must be
replaced.
STOPPING MACHINE WHEN MOWING
If 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 different times. This means that in order to maintain
same height-of-cut, which is a good practice, your need to
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 panicles
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 lawr:
shows through finely cut leaf cover. This may require one o:
more passes over leaves.
If there are more than five inches of leaves on lawn, raise:
mower one or two settings higher. This makes it easier tc:
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.
If you cut up a lot of oak leaves, you may want to add lime
to your grass in the spring, Lime reduces acidity of oak
leaves.
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
spindles after 50 hours use. Grease fittings are conveniently
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 should NOT be lubricated.
BLADE MAINTENANCE
ZN CAUTION A
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.
Tea,
FIG. 18 Front Puiley and Pivot Grease Fittings
To obtain optimum mowing results, mower blades should
be kept sharp and well balanced. To sharpen blades,
remove mower from machine and invert mower. Remove
blades using optional Toro Wheel Horse 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
