Help Identifying Plow!

First time owning a full on truck plow! I just purchased it cheap in plans of using next winter, we are over plowing our large property with a quad.
Need some help identifying the type of plow it is! Will be purchasing a electric hydraulic pump and could use some recommendations on a pump for it. I’ve seen a cheap option on vevor for around $350 Canadian but does not have a float option. Is this something that is necessary or is it okay to just lower all the way?
Thanks I’m advance for the help!
