Introduction
The 4200 Series Cobra from McFarlane Mfg. is our latest
development in Universal Tillage®and can satisfy all
of the demands of today’s farming practices, especially
BT corn and corn on corn cropping. This tool features
wavy, serrated Cobra disk blades, loosens the top one to
four inches of the soil yet leaves the seedbed rm. This
ensures accurate seed depth at planting, resulting in even
emergence and better yields. Smoothing uneven ground
and removing small weeds are done quickly at the 7-9mph
operating speeds.
The Cobra is available in a 12’ and 14’ wide rigid frame,
as well as 20’, 25’, 30’ 35’ and 45’ folding frames. The
horsepower required to pull the Cobra is approximately 8-9
hp per foot of width. Therefore the 12’ Cobra requires as
little as 100 hp while the 45’ requires up to 405 hp.

Safety
General
Safety of the operator and bystanders is one of the main
concerns in designing and developing a new piece of
equipment. Designers and manufacturers build in as
many safety features as possible. However, every year
many accidents occur which could have been avoided by
a few seconds of thought and a more careful approach to
handling the equipment.
Most work related accidents are caused by failure to
observe basic safety rules or precautions. An accident
can often be avoided by recognizing potentially hazardous
situations before an accident occurs. As you assemble,
operate, tow, or maintain the Cobra (unit), you must be alert
to potential hazards. You should also have the necessary
training, skills, and tools to perform any assembly or
maintenance procedures.
Improper operation and maintenance of this unit could
result in a dangerous situation that could cause injury or
death.
WARNING
Do not use or tow the unit until you read and
understand the information contained in this
manual.
Safety precautions and warnings are provided in
this manual and on the unit. If these hazard
warnings are not heeded, bodily injury or death
could occur to you or to other persons.
McFarlane cannot anticipate every possible circumstance
that might involve a potential hazard. The warnings in this
manual and on the product are, therefore, not all-inclusive.
If a method of operation not specically recommended by
us is used, you must satisfy yourself that it is safe for you
and for others. You should also ensure that the unit will not
be damaged or be made unsafe by the methods that you
choose.
The information, specications, and illustrations in this
manual are based on the information that was available at
the time this material was written and can change at any
time.
