Restoring rimu floor boards in kitchen

We have pulled up old lino, and stripped glue off. Need a sander to finish and seal the floor - I think it is rimu or tawa. It is a very small kitchen/laundry area. My guess is approx 10sqm. There is one chipped section on one of the floor boards which will need attention (can it be filled with something?) and am including a photo of this as well.
