Norwesco 2635 Gallon Horizontal Elliptical Leg Tank in Black

On a trailer or in the yard

At 140 by 90 inches the tank needs a trailer deck or a cradle that supports the full length of the moulded legs; a full tank is a load of eleven to sixteen tons, all of it carried through the legs into whatever is underneath. On a trailer, that means the running gear and the frame are rated for the full weight of the liquid you carry, not for water alone, and the tank is strapped through the leg recesses with the straps bearing on the body, never on the manway. In the yard, the tank sits on a level, continuous cradle or pad that touches every leg, with room at the outlet end for the valve and the hose. Our guide to Norwesco applicator and leg tanks for fertilizer and the DOT non-roadable trailer rules covers how a tank this size is classified on the road.

What goes in it

Water, liquid fertilizer and the common farm chemicals that polyethylene handles are the normal loads. Before anything else goes in, check the liquid in our chemical compatibility guide; the entries for urea solution, DEF, calcium chloride, magnesium chloride and sodium carbonate are the ones leg tank buyers ask about most. Liquids heavier than 1.5 times water need a heavy duty tank, not this one. If you blend fertilizer in it, read our note on fertilizer blend stratification first. For the volume itself, use the tank sizing calculator and tank sizing guide.

Openings and fittings

1. Outlet. A 3 inch polypropylene female NPT bulkhead fitting, factory installed low in the end wall, supplied with a 2 inch reducer. Run it at 3 inches for fast transfer to a sprayer or an applicator, or thread the reducer in and use 2 inch hose and a 2 inch valve. Support the valve and the first length of hose so the fitting carries liquid, not hardware.
2. Manway. A 16 inch threaded vented manway on top: wide enough to fill from a hose or a pump, to drop a float in, and to get a hand and a brush inside to clean. The vent lets air in as the pump draws down.
3. Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the exact outlet and manway positions and the leg layout for cradle and strap planning.

Shipping and receiving

The tank ships LTL from the nearest of Norwesco's plants in Griffin, Georgia; Hanford, California; Lancaster, Ohio; Shawnee, Oklahoma; St. Bonifacius, Minnesota; or Tooele, Utah, as a 140 by 90 by 72 inch load at 830 lb. That is a flatbed load, not a liftgate, so have a forklift or a loader with straps ready. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At the tailgate, check the part number against 40751 on the bill of lading, look at all the legs and the outlet fitting for transit damage, and fill the tank with water the first time before it carries anything else.
