Dear Owner:
You now own one of the finest rear-tine tillers available.
Your new PTO Horse Model tiller enables you to till and
cultivate your garden with ease, and accomplish dozens of
other property management projects as well. Its PTO
(Power Take Off) capability enables it to power a variety of
attachments, including a chipper/shredder and a log
splitter. Your tiller is famous for its ruggedness, perfor
mance and high-quality engineering. We know you'll enjoy
using it.
Please carefully read this Manual. It tells you how to safely
and easily assemble, operate and maintain your machine.
Be sure that you and any other operators carefully follow
the recommended safety practices at all times. Failure to
do so could result in personal injury or property damage.
Of course, if you should ever have any problems or
questions, please contact your local authorized service
dealer or call the Factory (see back cover). We want to be
sure that you are completely satisfied at all times.
NOTE: Be sure to fill out and return the Owner Registration
Card included included with this manual.
