DRAW
BAR
PULL

The
power plant of the 'Jeep* Universal is particularly well adapted to the great variety of ap­
plications. For higher speed highway use, and draw bar
pull
requirements for towing loads, the

full
engine
power is available; for power take-off shaft and pulley drive, the
full
engine
torque
(turning
effort) is available.

Draw
bar
pull
is the force exerted by a vehicle to tow a trailed load and is expressed in pounds.

For
continuous
agricultural
work, the maximum draw bar
pull
should be limited to 1200 pounds [544 kg.]. The 'Jeep' Universal is capable of much higher draw bar pulls than the 1200 pounds
approved for continuous service, which may be used for starting loads or towing loads for short
periods on
good
ground in which case a draw bar
pull
as high as 1800 pounds [817 kg.] may be
safely used.

Maximum
continuous draw bar pulls are most
often
encountered in plowing, disking and
har­

rowing
and it is in
these
applications that the owner should guard against continuously exceeding
the recommended limit.

The
approved limit of 1200 pounds [544 kg.] may be judged by the following operations which

nearly
approach this limit:

Operating
two 12 inch [30,5 cm.] plows at a depth of 6)4 inches [16,5 cm.] in dry clay loam.
Operating
a 7
foot
[2,13 meter] tandem disk at a depth of 4j^ inches [11,4 cm.] in
hard

winter
packed soil.

Operating
a 3-section spring
tooth
harrow at a depth of 5 inches [12,7 cm.] in soil which
has been previously disked.

It
is expected that, either on account of soil conditions or implement adjustments,
these
draw

bar
pulls
will
be exceeded. In
these
instances, tire slippage provides an inherent safeguard against
overloading. Do not add weight, other than the standard bumper weight, to increase draw bar
pull.
