VENTRAC Two-N-One 70.2001
The 2-N-1 fits the front of either 3000 or 4000 series tractor and combines the 2" receiver tube for towing with a Front Counter-Weight Bracket capable of holding six 42 lbs (19 kg) weights. With the optional weight extension bar (cannot be used with the hitch), the 2-N-1 can hold up to ten weights.
The Front Counter-Weight Bracket is designed for stabilizing the tractor when heavy equipment is mounted on the rear. This is very useful when operating attachments with the 3-Point Hitch, and keeping weight transferred to all four wheels.
