Hitch ‘N Plow® is available on Amazon. Just click on the link for the adapter. You will also need a winch, category 1 farm implement (which you could purchase from Amazon or your local Tractor Supply), and a battery jumper box to be able to power the winch from the rear of the truck/SUV.
UPDATE: Behlen is no longer offering “Hitch ‘N PLow” on Amazon but it is available via the Global Industrial site. Click on picture to go to the site to purchase.
Here are some links to Amazon for winch, battery and category 1 box blade and grader blade options. Note: The links below are Amazon Associate links and I earn commissions from qualifying purchases.
