:thumbsup: Get as much ballast on the rear tires as possible. Load tires and axle weights if possible.I don't think you will have any problems with sufficient power to pull. The problem will lie with sufficient weight & traction. Does the tractor have sufficient weight to provide the traction needed. You don't want to get into a situation where the "load" is requiring more traction than the tractor can provide.
Your tractor lists at 4130 to 4566 pounds without FEL or added weight. I would hook it up and try it on level ground and see how it acts.
