GENERAL INFORMATION

This manual applies to the following BigDog

®

 Mowers

equipment lines:

BigDog

®

 Mowers Alpha MP

To The New Owner

The purpose of this manual is to assist owners and operators

in maintaining and operating your BigDog

®

 Mower. Please read

it carefully; information and instructions furnished can help you
achieve years of dependable performance.

A separate Engine Owner’s Manual is included with your

owner’s packet which contains additional engine information
that will not be repeated in this manual. It is the owner’s
responsibility to make certain that the operators and mechanics
read and understand the engine owner’s manual before
attempting to operate or repair the engine. 

The decals are designed to give the operator brief information

needed in the daily operation and service of the machine. These
decals are not intended to be used in place of this manual but
instead are to be used as an extension of this manual. These
decals should not be removed or obliterated. Replace these
decals if they become unreadable. 

It is the 

owner’s responsibility

 to make certain that the

operators and mechanics read and understand this manual and
all decals before operating this machine. It is also the 

owner’s

responsibility

 to make certain that the operators and mechanics

are qualified and physically able individuals, properly trained in
the operation of this equipment. All operators and mechanics
must become familiar with the safe operation of the equipment,
operator controls and decals.

IMPORTANT:  

The owner/user can prevent and is responsi-

ble for accidents or injuries occurring to themselves, other peo-
ple or property.

Never let children or untrained people operate or service the

equipment. Local regulations may restrict the age of the
operator.

For more detailed maintenance and adjustment information

refer to the proper 

General Service Manual

 for your machine.

Refer to the 

“Product Literature”

 section of this manual for

information on how to attain these manuals.

Using This Manual

General operation, adjustment and maintenance guidance is

outlined for both the experienced and novice BigDog

®

 Mowers

user. Operating conditions vary considerably and cannot all be
addressed individually. Through experience, however, operators
should find no difficulty in developing good operating skills
suitable to most conditions.

Directions used in this manual, for example RIGHT or LEFT,

refer to directions when in operator position and facing forward,
unless otherwise stated.

Photographs and illustrations used were current at the time of

printing, but subsequent production changes may cause your
machine to vary slightly in detail. BigDog

®

 Mowers reserves the

right to redesign and change the machine as deemed necessary,
without notification. If a change has been made to your machine
which is not reflected in this operator’s manual, or the parts
manual, see your BigDog

®

 Mowers Dealer for current

information and parts.

Warranty Registration

Your BigDog

®

 Mowers Dealer must register the unit on-line

within 

ten (10) days

 following date of purchase to validate your

warranty protection. As the new equipment owner, you should
confirm that your BigDog

®

 Mowers Dealer has registered your

mower with BigDog

®

 Mowers.

Be sure to register the mower plus each attachment that

displays a model and serial identification number plate with
BigDog

®

 Mowers.

IMPORTANT:  

Any unauthorized modification, alteration,

or use of non-approved attachments voids the warranty and
releases BigDog

®

 Mowers from any liability arising from subse-

quent use of this equipment. Do not use or operate any attach-
ment not approved by BigDog

®

 Mowers.

Model And Serial Number

Mower model and serial numbers are found on the serial

identification plate, located on the left mower frame side rail.

These numbers are required when the unit is registered with

BigDog Mowers. They will also assure you of the correct
service parts when replacement becomes necessary.

®
