ID The ST15 (Jan 2002 to Current)
The ST10 & ST15 was built from Jan. 2002 (s/n
Current) .
Serial Numbers:
See The Index Pages for an explanation on of how to identify your unit by the 12 digit serial number
code, The Serial number code shows manufacturing production date of your unit.
Gearboxes:
The best way to ID the ST10 & ST15 (Stingray Model) is by the Gearboxes, This is a 4 Gearbox
Model (Divider and Center Blade Gearbox two separate gearboxes). The Divider gearbox has a 1-3/
8" X 21 Spline Output Shafts. The Blade Gearbox (Center & Wings) has a long section of the Housing
that protrudes below where it bolts to the deck. The Blade Gearbox has a Dip-Stick type top Plug. The
Blade Carrier Retaining Nut used a Cone Shaped Washer which no other model has to this time.
Blade Carriers:
The Blade Carriers are a Round Shaped Pan Weldment. The Blade Bolts are a Shouldered Blade
Bolt, and a bushing is used with the Blade Bolt. This was not the only 4 gearbox model that had a Shoulder
Blade Bolt but is the only model to use a bushing with the Shoulder Bolt.
Driveline Options:
There were no Driveline size options, There was a Cat IV (4) Wing Drivelines and a Cat V (5)
PTO Driveline used on this model. Some parts will not interchange between drivelines. See Part numbers
for interchangeable parts.
ST15-C31200557203) to Current (s/nST-
Axles:
The axles are Independent from center to wings. The type Hydraulic Axle lift is a Phasing (Slave)
Cylinder system, the Hydraulic lift of the mower is done by using 3 hydraulic Cylinders mounted one in
the center and one on each wing. The Cylinders are connected together into one Hydraulic flow in series.
Note: Item # 3 is the standard Tongue Hitch Clevis , there is an Optional Hitch Clevis
offered called Precision Hitch Kit # 02978611. See Parts break down for this optional
hitch.
Attach the wheels to the hubs. If puncture-proof, Laminated Tires and Wheels are used,
be sure the flat side of the nut is against the Wheel. Tighten wheel bolts to 85 ft/lbs. Note
direction of travel and curvature of rubber segments in tire and install as shown below to
give longest tire life.
When the Spindles a re installed and mower is being readied for use. The Spindles in the
Center Axle need to be adjusted to give the desired trailing width, this determines where
the Wheels runn inline with the mower and the wheel track width. this will need to be done
once and should not change unless it is unbolted and moved.
NOTE: To adjust this Slip Clutch tighten Bolts, (item 9) untill Springs, (item 2) are a
compressed length of 1-1/4" as shown in drawing above. When tightening use an
alternating pattern in a cris-cross pattern.

NOTE: Gearbox Gear ratio 540 or 1000 RPM is the same, 1 in : 1.35 out, the gear ratio
between the 540 & 1000 RPM output will be determined by the Gear ratio of the divider
Gearbox. Right and Left Wing Gearboxes use the same components, it is where the Input
gear (item 21) & Top Cover (item 20) is installed that makes them different.

Section of mower as part of Wing Axle. See Deck Components Section for these parts
NOTE: These are Phasing (Slave) Cylinders and must be connected as shown, Large Bore
Cylinder, Medium Bore Cylinder and then Small Bore Cylinder. The Cylinders will have to be
free of Air, this means cylinders must be bled and remain an air tight system to prevent air
from entering cylinders. See Operators manual for procedures to connect these cylinders.
See drawing below shownig how oil is bypassed through the Cylinder to the next Cylinder
when Cylinders are stroked completly out.

The Wing Cylinder attachments may need adjusting to level the Wing Axle to the
Center section Axle. These parts are listed in the Deck Component Secton
of parts manual.
Leveling will rquire that the mower is placed on a level surface with the full weight
of the mower on the tractor Draw Bar. The Cylinders must be connected and Bled. Lower
the Wings into the mowing position.
Locate the front to rear leveling rods (Control Rods), these are the rods that run from
center Axle to the Tongue. Adjust the control rods to level the mower from front to rear (on
the center section deck). Tightening (shortening) these control rods will raise the front.
Lengthening thes control rods will lower the front. Mower work best when the front is approx
1" lower than the rear. IMPORTANT that these control rods are tighten equal to where the
carry equal load. This can be check by tapping rod with ahammer and listening to the tone.
A loose control rod will have a dull sound compared to the tight one, tighten till they both
sound the same.
Adjust the Wing Axle Cylinder attachemnt. This will level the Wings with the center
section Left to Right. The Wing Adjus Weldment shown above is used for this. The Trailing
Nut and the Leading Nut will have to be moved together, as one is loosened the other will
have to moved. Moving adjust Weldment out will raise the wing and moving it in will lower
the Wing. When done make sure that both Nuts are tightened down.
2.9 Link sections of Chains are used and are hung by the 5 th link
to form the double Chain Guard. (See illustration below)
3.The Cables are laced through the Bottom Link of the Chain and
then a Cable Clamp is placed at each end of the Cable. (See
illustration below).
4.Front Center Section is in 3 pieces, 1 center (19 Chains) and 2 outer
(16 Chains ea.)
5.The Front Wings are 2 pieces (29 Chains ea.) on each wing, same
LH or RH. There are two Chain Sections that bolt to a lug on the outer
side of each wing.
6.The Rear Center is in 2 pieces (24 Chains ea.)which are both the
same LH or RH Center.
7.The Rear Wings use 3 pieces, The center and inner Wing piece are
the same (19 Chains ea.), the outer for the wings is different (18
Chains)
8.The Chains are held in with a steel rod that is welded to the chain
guard bracket. to change or install chain sections these rods should
be replaced and rewelded.
Qty. Shown above is all three pieces used on rear Wing section LH, RH and Center.
