IFEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
INTRODUCTION
The Model RB34 round baler is the smallest baler in the Challenger® variable chamber round
baler line. The RB34 baler is sized primarily for operators with lower horsepower tractors. The
RB34 is ideal for the smaller farmer who wants to move from small square bales to easier to
handle round bales. It is also ideal for the small farmer who wants to move away from hiring a
custom round bale operator and have more control over the timing of his baling. The RB34 is
also a good fit for the smaller farmer that is tired of the frequent breakdowns with used balers
and wants to move into a new, more dependable baler.
Although designed small, the RB34 has the inherent durability and capacity to satisfy a larger
operation that requires a small hay package. The RB34 bale can be used in operations where
a small hay package may need to be moved around to feed livestock and the bales are light
enough to move by hand or with a small tractor or skid steer loader, and small enough to be
transported through narrow doorways or alleyways. The Challenger® RB34 was designed to
produce high quality round bales with simple operation and easy to understand controls.

CHALLENGER® RB34 ROUND BALER
PRODUCT DESCRIPTION
The Challenger® Model RB34 round baler produces a 39” wide by 30” to 52” diameter (1.0 by
1.4 meter) hard-core bale, weighing up to 550 pounds (249 kilograms). The baler requires a
tractor with a minimum of 30 PTO horsepower (22 kilowatt), a 540-rpm PTO and a single
hydraulic remote outlet. In keeping with the Challenger® round baler model numbering system,
the last two digits of the model number depict the bale size. The last number in the model
number refers to the approximate width of the bale in feet (RB34). The second to last number
in the model number refers to the approximate maximum diameter of the bale in feet (RB34).
The Challenger® RB34 is a Class I (55 cu. ft. and under) baler with a bale chamber capacity of
up to 51.7 cu. ft. (1.46 cubic meters). It is capable of handling a wide variety of crops with
ease. The open throat, vertical bale chamber design provides a proven design that starts
bales easily and creates bales with consistent density. The variable chamber design of the
baler produces a hard-core bale with excellent storage characteristics, while requiring less
horsepower to operate than a comparable fixed chamber baler.
The Challenger® RB34 has a variety of options available to customize the baler for each
customer’s needs. These options include Gathering Wheels, Electric Twine Threader, Bale
Ramps and a Fire Extinguisher
2FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Variable Chamber Baler Design
Variable chamber balers work by “varying” the chamber size as the bale size increases. As
the crop enters the bale chamber, the belts and rollers expand to accommodate the growing
bale. Tension arm springs provide tension for bale density and the forming belts. Most
competitive variable chamber baler manufacturers combine the functions of bale density, and
belt tension on a single control arm. We find that we can obtain more consistent belt tension
and therefore more consistent bale density by separating the two functions. Consistent belt
tension also provides increased belt and lacing life. The bale density on the RB34 is preset at
the factory with large, non-adjustable tension springs.
The hard-core bale produced by a variable chamber baler provides consistent bale density
from the core to the outer shell. This characteristic allows the operator to vary the bale
diameter to meet his requirements or to wrap the last bale of the field.
MARKET
The Challenger® Model RB34 round baler is designed for operators needing a small, easy to
handle, bale package. The low bale weight and narrow width provide convenient handling,
transportation, and feeding for the customer. The RB34 is an excellent value, providing easy
serviceability and low maintenance, in a very cost effective baler. We are the only
manufacturer producing a round baler with a 3’ bale width.
3FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
GENERAL
Simplicity
The Challenger® Model RB34 round baler is small in design and large in capacity with very few
adjustments. Controls are simple to understand and easy to operate. This allows even the
newest operator to go to the field and start baling with very little training. This saves both the
owner and dealer time and costs associated with training new operators.
Equal Angle Hitch
The Challenger® RB34 is equipped with an
equal angle hitch and Power Take Off (PTO).
The tractor power is transferred through the
equal angle PTO for smooth operation while
turning under load. The equal angle hitch
prevents damage or excessive wear to the
driveline because there is less driveline vibration
and chatter during turns.
4FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Narrow Tongue
The narrow tongue allows the baler to make
short turns up to 80 degrees without the tractor
tire contacting the tongue. This permits the
operator to more efficiently bale in smaller fields
and to maneuver around field hazards. This
helps to make the RB34 a more productive unit.
5FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
PICKUP
Low Profile Pickup
The Model RB34 has a 38.8” (986mm) wide,
three tine bar, low profile pickup that provides
gentle crop handling. The “low profile” (small
diameter) pickup gently moves delicate hay crop
into the bale chamber with minimum disruption
or abrupt direction change. Crop loss is
minimized as fewer leaves are shattered from
the stem because our balers don’t have to lift
the crop as high to feed it into the baler. This
results in more profitability for the farmer
because more leaves, the highly nutritious part
of the plant, are put in the bale, and fewer
leaves are scattered back onto the hayfields.
Steel Windguards
The Challenger® RB34 has evenly spaced steel
windguards that control the flow of the hay on
the pickup. They help feed the hay into the
baler in an even mat. The tine spacing is 2.6”
(66 mm) to minimize the amount of crop falling
between the tines. This combination ensures
even feeding of the baler so the crop ends up in
the bale.
Easy Pickup Adjustment
The pickup lift is a simple manual lever located
on the left hand side of the baler tongue.
Manual lift was chosen because the pickup is
very light on this size of baler and most tractors
used on this size baler have limited hydraulics.
Just remove the lock pin, raise or lower the
pickup, replace the lock pin and you are ready
to go. It’s fast and easy to switch from road to
field, or field to road position.

CHALLENGER® RB34 ROUND BALER
MAINFRAME, ROLLERS AND BELTS
Sure-Trac™ Crowned Roller
The Sure-Trac™ crowned roller (upper drive
roller) drives the 4.8-inch (122 mm) wide forming
belts. The crowned drive surface centers the
belts and provides a positive drive surface,
resulting in longer belt life and less maintenance.
Centering of the belts and the aggressive drive
surface keeps the belts turning, even under
adverse conditions.
Forming Belts
The bale forming belts in the RB34 are 4.8” (122
mm) wide and are made of high quality,
synthetic fabric. The RB34 utilizes five belts
designed for long trouble-free service under high
loads. The drive side of the belt has a textured
surface for traction on the rolls, while the bale
forming side has a “mini-rough” surface to gently
but positively handle and compress the bale.
Belt Tracking Adjustment
Slotted holes on both the right and left sides at
the bottom of the tailgate make adjustments to
belt alignment very fast and simple. You don’t
have to climb on top of the baler to keep the belt
tracking true.
7FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Starting Roll
The Starting Roll (1) in the Challenger® RB34 is
a square tube that rotates to aggressively turn
the crop to start the “core” of the bale. Once the
core is started, the rest of the bale forms more
easily. Our square tube starting roll works well
in a variety of crops to start the initial core of the
bale.
The crop deflector (2) keeps the incoming crop
from wrapping around the starting roll and helps
keep short crop from bunching up in the
pickup/throat area.
Balanced, Dual Arm Tension System
The Dual Arm tension system provides optimum bale density and consistent tension to the
bale forming belts throughout the baling cycle. Some other manufacturers provide tension only
on one side of the baler and try to transfer the tension to both sides through torsion tubes.
This uneven application of tension causes frame flexing, which in turn causes belt mis-
tracking. This can cause premature belt failure and poor bale formation. Most other
manufacturers of variable chamber balers use a single control arm to apply bale density and
belt tension. By separating these functions, we can get better belt tension control from core to
maximum bale diameter. With less instantaneous belt slippage, we get more consistent bale
density.

8FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Over Size Protection
A pickup declutcher provides the baler
protection from damage that could occur if an
oversized bale is produced. The declutcher rod
disengages the pickup drive when the maximum
bale size has been reached. This prevents
additional crop from entering the bale chamber
and forcing the bale forming belts that are
traveling in opposite directions from contacting
each other. Belt life will be prolonged and
undue stress on the baler will be prevented.
Bale Size Indicator, Bale Full Alert
The Challenger® RB34 utilizes a simple
mechanical bale size indicator (1) that is easily
visible on the front, right hand side of the baler.
The indicator provides bale size information,
allowing the operator to check the bale size at
any time during the baling process. The
operator has complete control of the bale size
from the tractor seat. By monitoring the bale
size indicator the operator can start the tying
cycle at a smaller than full size bale if desired.
The Bale Full Alert (2) warns the operator when
the selected bale size is reached. A sprocket
attached to the sizing roller arm, contacts the
alert rod causing a sharp ratcheting sound. To
change the desired bale size, the operator
adjusts the alert rod.
9FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
BALE WRAPPING
Twine Tie
The Challenger® RB34 comes with a manual
twine tie system as standard equipment. A pull
rope twine tie provides an effective, economical
bale tying system. This system is designed for
tractors with limited hydraulic capacity. The
operator controls the twine spacing by the speed
at which the rope is released. An optional
electric twine tie kit may be added.
Twine Arm Indicator
The RB34 includes a twine arm indicator that
provides a visual monitor of the twine arm
position as the bale is being wrapped. The
indicator allows the operator to gauge the
position and amount of twine being placed on
the bale.
Twin Tube Twine Arm
A new feature on the RB34 is the
TwinTubeTwine Arm. The double tube twine
arm applies two twines to the bale
simultaneously. This allows the operator to
wrap the bale in half the time of the 6343 or
4643 balers. This makes the baler more
productive. The spacing between the two twine
tubes is adjustable from 2” to 6” to allow the
operator flexibility in twine application
10FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Twine Cutoff
The twine is pulled over an anvil when the twine
arm comes back to the home position. As the
twine arm returns to home position, it activates a
mechanism that pulls a blade down onto the
anvil, which cuts the twine and leaves enough to
start the next tie cycle.
Twine Storage
The twine storage box on the RB34 is between
the A-frame members of the tongue. The twine
box holds two balls of twine, which will wrap
about 300 bales at a 4”, twine spacing. This
location allows easy access for loading twine.
The twine is easy to thread in the RB34 because
the twine storage is close to the twine arm and
there are no long tubes to feed the twine
through.
Tailgate Indicator Rod
The tailgate indicator rod projects from the right
top of the baler. It shows the operator when the
tailgate is latched or unlatched. The right hand
tailgate cylinder operates the tailgate indicator
rod. The rod is visible to the operator when the
tailgate is not latched. The rod disappears from
view when the tailgate is latched. This indicates
that the operator can begin to make the next
bale.
11FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Bale Counter
A resetable mechanical bale counter is standard
equipment on the Challenger® RB34. Many
more expensive balers from other manufacturers
only offer bale counters as optional equipment.
The bale counter is advanced each time the
tailgate is cycled. It is resetable so the operator
can keep track of the bales per field, per job or
per day as he sees fit.
Lighting
The RB34 meets the latest A.S.A.E. Lighting and Marking Standard for Agricultural Equipment.
It includes amber warning flashers, red tail/brake lights with a standard 7-Pin connector to plug
into the tractor. There is also an SMV emblem on the back of the tailgate.
12FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
OPTIONAL EQUIPMENT (FIELD INSTALLED)
Windrow Gathering Wheels
The Windrow Gathering Wheel option increases
the effective operating width of the pickup. This
helps the operator feed more crop to the edges
of the bale chamber to make firm walled, square
shouldered bales that will retain their round
shape and not squat down while in storage. The
gathering wheels help build a more dense,
weather resistant bale that will shed moisture
and preserve more of the crop for less storage
losses.

13FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Bale Ejection Ramps
The optional Bale Ramp Kit includes two spring
loaded ramps that allow the operator to bale
without backing up to eject each bale. When the
tailgate is opened, the weight of the bale forces
the ramps down. The bale then rolls down the
ramps, which spring back up as soon as the
bale rolls off of them. When the ramps spring
back up, they hold the bale from rolling back into
the path of the tailgate as it is closed. This
allows more productive baling.
Wholegoods Kit – BK50641
Estimated Installation Time – 0.5 Hr.
Electric Twine Tie
The electric twine tie control moves the twine
arm with an electric actuator. A toggle switch,
which controls the actuator, can be mounted on
the tractor for the operator’s convenience. The
operator controls the twine spacing and number
of wraps with the toggle switch instead of with
the manual rope pull twine activator. The
electric twine control kit can be used with a
tractor that has only one hydraulic valve.
Wholegoods Kit - BK51065
Estimated Installation Time – 2.5 Hrs.
14FEATURES AND BENEFITS
CHALLENGER® RB34 ROUND BALER
Fire Extinguisher Kit
Due to the flammable nature of hay crops, it is
advisable to purchase a fire extinguisher and
mount it in a convenient location on the baler. A
2½ gallon stored pressure water fire extinguisher
with mounting bracket, hardware, and complete
instructions is included in the kit.
