What you need is a mine clearance flail tank
Here is an animation showing it at work, with a video linked
These are based on M4 Sherman tanks and still have the standard weaponry in addition to the flails.
Fuel capacity 138–175 U.S. gallons (522–662 litres) depending upon variant
Operational range 100–150 miles (161–241 km) on road depending upon variant
Speed 22–30 mph (35–48 km/h) on road, depending upon variant

EDIT
The question has been edited to require the inclusion of hand-to-hand fighting. I have two suggestions:
1. A hand flail
2. A chainsaw
