Introduction Section 2-3
INTRODUCTION
The Bush Hog 3308 Series Rotary Mower is designed for medium duty applications such
as weed, grass, corn stalks, and light brush to 2" diameter. These mowers are multi spindle
with two free-swinging blades on each spindle. Free swinging blades reduce the shock of
impact when a stationary object is hit. Additional protection is provided by a slip clutch on
the gearbox input shaft and a rubber element shaft between gearboxes. A round blade holder
allows the mower to “ride over” stumps and similar immovable objects. These Mowers are
attached to the tractor using 3- point Cat I & II standard and quick hitches, and pull hitch,
and CAT I & II semi-mount swing hitch. Standard equipment includes driveline shields, clutch
shields and front and rear discharge shields.
INTRODUCTION
The 3308 Series is shipped from the factory with the Front and Rear Safety Enclousers
assembled to the cutter. The enclousers can be Single Row or Double Row chains on the
front or Single Row Chains, Double Row Chains or a Metal Band to the rear.
INTRODUCTION
These Enclousers should be maintained in good working order and remain attached to
the cutter when operating in conditions may present a Thrown Object Hazard to Humans
or Livestock.

INTRODUCTION
KEY OPERATION POINTS
• Cutting performance and distribution are best when cutter is level from side to side and front to rear.
In extra heavy material, rear chains will allow better discharge and better distribution than solid rear
deflectors or bands.
• Never operate the Mower below full PTO speed of 540 or 1000 rpm.
• Corn should be cut at 5 to 6 mph. If full PTO rpm cannot be maintained, use one lower gear.
The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below
the levels from typical Agricultural tractors used to power and transport this machine. Therefore, the Noise
emission values given by the OEM of the Agricultural tractor used to power and transport this machine would
be valid when this machine is attached to and operated by that Agricultural tractor in all OEM recommended
applications.

Tractor Safety Devices
If transporting or operating the tractor and implement near a public roadway, the tractor must be equipped
with proper warning lighting and a Slow Moving Vehicle (SMV) emblem which are clearly visible from the
rear of the unit. Lights and a SMV emblem must be equipped directly on implements if the visibility of the
tractor warning signals are obscured.
Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were
removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO
with the PTO master shield missing or in the raised position. OPS-U- 0004
The power required to operate a mower is determined by the tractor PTO horsepower. For most mowing
conditions, the 3308 Series lift mower requires a tractor with at least 50 HP and the semi-mount and pull
type mower require at least 40 HP. Operating the mower with a tractor that does not have adequate power
may damage the tractor engine. Exceeding 90 HP may cause mower damage by overpowering the unit in
heavy cutting conditions.
3-Point Hitch
Lift Type Mower-The tractor 3-point hitch must be
rated to lift at least 1850 lbs.
Top Link
attaches
here
The Model 3308 Series is designed to be mounted
on a tractor with CAT I or CAT II 3-point or CAT I or
CAT II Quick Hitch.
Refer to the tractor operator’s manual for the category of the tractor being used. If the hitch does not
conform to ASABE dimensions, the mower may not
fit or raise properly. Consult an authorized dealer for
possible modification procedures to mount non-conforming hitches.
Depending on the hitch category, certain size pins
are used to attach the mower to the tractor. Quick
Hitch requires 1-7/16 diameter lower pin and 1-1/4
diameter upper pin. CAT II hitches require 1-1/8 lower
pins and 1 inch upper pins. CAT III hitches require
1-7/16 lower pins and 1-1/4 upper pin diameters.
Our 3-point Quick Hitch is designed to connect to a
Quick-Attach coupler making mounting and dismounting your mower easier. The 3-Point Quick
Hitch is also designed to connect the mower to a
tractor’s 3-point linkage without the use of a Quick
Attach Coupler.

Setting Mowing Height - Pull Type
1. Park the tractor and mower on level ground.
2. Using the hydraulic cylinder or ratchet attached
to the rear axle position the front skid shoes 1”
less off the ground of the desired mowing height.
(Example: If a 3” cut is desired Place the Skidshoes at 2” off the ground.) If a hydraulic cylinder
is used for height control, stroke spacers can be
placed on the cylinder rod to maintain a set cutting height.
2. Adjust the two Leveling Rods so the front of the
mower is approximately 3/4” lower than the rear.
3. Level Rod adjustment is achieved by loosening
the lock nut against the clevis and screwing the
Level Rods in or out to set desired setting.
4. Be sure Level rods are equally set to maintain a
level cut.
5. Tighten the Lock Nut against the clevis to maintain the setting.

El distribuidor deberá informar al comprador de este producto las condiciones, disposiciones y procedimientos de
garantía aplicables; informar la responsabilidad del comprador de capacitar a sus operadores para la operación
segura; revisar el contenido del Manual del Operador, incluido el equipo de seguridad, la operación segura y el
mantenimiento; y revisar las Señales de Seguridad que se encuentran en el implemento (y en el tractor, de ser
posible).
IMPLEMENTOS PLEGABLES: He explicado que no es posible proteger contra objetos arrojados cuando el
cabezal está elevado del suelo y que el operador es responsable de verificar que no existan personas en las
inmediaciones. He explicado que el brazo o cabezal de cortadora elevado puede entrar en contacto con
obstrucciones elevados y dañar cables y líneas telefónicas, y posiblemente causar lesiones. He explicado que
el brazo o cabezal extendido, o el brazo retraído, puede entrar en contacto con cables de alimentación y
causar lesiones o la muerte por electrocución, y que el operador es responsable de evitar dichos riesgos.
•
MÁQUINAS HIDRÁULICAS: He explicado la necesidad de usar aceite hidráulico limpio, cambiar los filtros
según las instrucciones, detener filtraciones, prevenir daños por operar con aceite demasiado caliente, cuidar
las mangueras, usar mangueras del tipo correcto, mantener la presión operativa especificada y prevenir el
posible riesgo de que el aceite penetre en la piel.
•
LÍNEAS DE CONDUCCIÓN: Me he asegurado de que todos los protectores de líneas de conducción, de caja
de engranajes y otros están en buenas condiciones de reparación y firmemente sujetados para prevenir
lesiones por enredo u objetos arrojados.
•
IMPLEMENTOS: He explicado que los deflectores, protectores de cadena o faldones sólidos se deben
mantener en buenas condiciones de reparación y se deben instalar, excepto en zonas donde personas,
vehículos, ganado u otros bienes no corran peligro por objetos arrojados, y en los casos en que dichos
equipos de seguridad impedirían un desempeño razonable de la cortadora en su tarea asignada.

A fin de reducir la tasa de accidentes y mejorar la operación segura de las cortadoras, Alamo Group Ag Division se
ha asociado con otros fabricantes de la industria para desarrollar el video y la guía de Prácticas de Seguridad para
Cortadoras Industriales y Agrícolas AEM/FEMA.
El video explica a los operadores de tractores y cortadoras las prácticas seguras que deben adoptar cuando
utilizan cortadoras industriales y agrícolas. Es importante que todos los operadores de cortadoras aprendan cómo
operar sus equipos de corte y puedan reconocer los posibles peligros que pueden surgir al operar una cortadora.
Este video, en conjunto con el manual del operador de la cortadora y los mensajes de advertencia que se
encuentran en la cortadora, serán muy útiles para complementar este aprendizaje tan importante.
Es posible que su distribuidor autorizado de Bush Hog le haya mostrado este video y le haya entregado una copia
en DVD cuando adquirió su cortadora. Si usted o algún operador de cortadora no vio el video: mire el video, lea
este Manual del Operador, y complete la Guía del Video antes de operar su cortadora nueva. Si no comprende
alguna de las instrucciones del video o del manual del operador, o si tiene alguna pregunta acerca de la operación
segura, comuníquese con su supervisor, con el distribuidor o con Alamo Group Ag.
Si desea recibir una copia del video en VHS, envíe un mensaje de correo electrónico a [email protected] o un fax al (830) 372-9529, o envíe por correo una copia rellenada del formulario que se encuentra al
dorso de esta página a AEM VHS Video 1502 E Walnut Street, Seguin, TX 78155, y solicite la versión en VHS.
Indique su nombre, dirección postal, modelo de cortadora y número de serie.
Cada uno de los operadores debe recibir capacitación para cada equipo (tractor y cortadora), comprender el uso
previsto, y comprender los posibles peligros antes de operar el equipo.
