danger of suddenly sliding sideways or down the
hill. On moderate hills reduce speed and use
caution. When operating on a slope, travel across
the grade, whenever possible, not an up or down
pattern. Reduce speed and exercise extreme
caution on slopes and in sharp turns to prevent
tipping or loss of control. Be especially cautious
when changing direction on slopes.
When pointing up a slope, the Sentar has the
most weight on the drive wheels and therefore the
most traction at the tires. However, this is the
angle that it has the most tendency to tip back
(“pop a wheely”). This is the preferred angle for
mowing small areas of steeper slopes.
Recommendations for this angle:
 Lean as far forward as possible and stand if
necessary to add your weight to the front
of the mower.
 Accelerate gently. Do not accelerate quickly
to avoid "popping a wheely”.
 If backing down the hill do not stop suddenly,
but slow down gradually.
When pointing down a slope, the Sentar has
the least weight on the rear drive wheels and
therefore the least traction at the tires. This is the
angle that the mower has the most tendency to
slide. However, this is the angle that it has the
least tendency to tip back. Avoid this angle, as it
has the least advantage for the Sentar.
Recommendations for this angle:
 Stretch your arms out straight while holding
onto the stationary handlebar and sit back
as far as you can on the seat. This adds
more of your body weight to the drive
wheels for more traction.
 Do not change speed suddenly to minimize
the tendency of going into a slide. Acceler-
ate and deccelerate gently. If you ever go
into an uncontrolled slide while pointing
down a slope the recommended proce-
dure is to let go of the handles and jump
off if necessary. Otherwise, control the
mower gently and stay off slopes that tend
to make the wheels slide.
When crossing a slope sideways, the Sentar

has the average amount of weight on the drive
wheels versus the front wheels, similar to level
ground. However, this angle leaves the least
weight on the higher side drive wheel, tending to
make it slip. This is the preferred angle for mowing
large areas of gentle slopes.
Recommendations for this angle:
 Sit back, as far as you can on the seat. This
adds weight to the rear drive wheels and
will allow you to mow more quickly across
the slope without sliding. If your Sentar is
equipped with the optional weight bar on
the front, the mower may not handle as well
crossing slopes as a Sentar without the
weight bar on the front. Weight on the front
of the mower reduces the traction of the
rear drive wheels and can cause the mower
to slide or nose dive down hill. Use of the
optional weight bar is determined by the
width of cut of the mower and the operator's
weight. For 48" and 52" cut mowers,
operators over 220 pounds may prefer the
optional weight kit. For 61" cut mowers,
operators over 280 may prefer the optional
weight kit. Remember it is recommended
that operators weigh at least 120 lb. and not
more than 350 lb.
 Do not accelerate quickly to minimize the
tendency of "popping a wheely”.
Note: Excessively worn tire tread is dangerous.
Replace tire(s) with less than 3/32" of any tread
groove left. Use tires with the tread pattern recom-
mended by Wright Mfg., Inc. only. Keep the tire
pressure in the drive tires between 20 and 24 psi.
Higher pressures will cause the tires to have less
traction which may prevent safe operation.
Operation During Zero-Radius Turns:
During zero-radius turns (when one mower wheel
rotates backwards while the other rotates forward)
drive extra slowly to reduce the possibility of losing
traction, or control, or becoming dizzy. This will
help prevent you from being thrown off of the
mower. Be aware that if you do a turn on a slope
you may go through all of the orientations to a
slope mentioned above and must handle the
mower accordingly.
