This is advertised as available at select Lowe's. If you have a need for this modular system quite the deal. The power base alone is $399, now free. You must buy $248 or more of in stock Flex attachments. This could mean buying two or more of the cheaper attachments.
Available attachments include pressure washer, bagger, leaf blower, snow blower, and lawn mower base. Looks like a nice system.
Check the available attachments, it may work out for you.
