The attacking midfielder spoke to iFollow Iron after putting pen to paper.
He said: "I'm delighted to have joined. I've been speaking to the gaffer (Keith Hill) and he knows what he wants, and I can't wait to get going now and get up that league for him and the fans.
"I'll bring direct pace, a bit of trickery and will hopefully get some goals as well. I'll work hard for the team in and out of possession. I like to take set-pieces too.
"I can't wait to get on the pitch, maybe even tomorrow night (against Bristol Rovers).
"I had a good back-end of last season, scoring a couple of goals and starting most weeks. The gaffer at Mansfield (Nigel Clough) made a couple of signings (in his position) and I knew it was going to be hard. They're going along well now so I thought it was time to get some games under my belt.
"(Keith Hill) spoke well about me and told me how he rates me so I want to try and play every week and help the team up the table. I don't mind that pressure. I hear it's a good set of lads and I'm sure we'll get up the table.
"I already know Jai Rowe and have done for a couple of years, but I've played against most of them last season and this season."
He concluded: "I just want to score as many goals and get as many assists as I can, and get the team up the league."
