A 70 gallon applicator saddle tank for the side of a tractor or a sprayer frame
The Norwesco 70 gallon applicator saddle tank in white, part number 44237, is a polyethylene tank shaped to hang on the side of a tractor or an applicator frame rather than sit on a deck: 44 inches long, 23 inches wide and 26 inches tall, weighing 25 lb empty. Saddle tanks are bought in pairs more often than singly, one each side, so the machine stays balanced and the operator keeps a clear view. It comes with a 3/4 inch polypropylene female NPT bulkhead fitting as the outlet and a 5 inch threaded vented lid on top. The tank is rated for liquids up to 1.5 specific gravity, a maximum of 12.52 lb per gallon, which covers water, liquid fertilizer and most crop chemicals; 70 gallons of water weighs about 580 lb. The resin is FDA compliant per Norwesco, the service limit is 120 F (48 C), and Norwesco backs it with a 3 year warranty. White shows the level from the seat.

Where a saddle tank goes
A saddle tank carries starter fertilizer, herbicide or water alongside the tractor so the planter or the cultivator behind it can draw as it works, without a nurse trailer in tow. The 70 gallon size suits a compact or mid size tractor and a small applicator frame; two of them double the carry with the weight split evenly across the machine. The mounting brackets are specific to the tractor and come from the tractor side of the job, not from the tank, so have the bracket plan before the tank arrives and confirm the bracket spacing against the drawing linked on this page. Full of water each tank carries about 580 lb on top of the 25 lb tank, and a pair doubles that on the front axle or the frame rails, so check the machine's rating. Our guide to Norwesco applicator and leg tanks for fertilizer and the DOT non-roadable trailer rules covers how applicator tanks are treated on the road, and the farm fleet DOT classification guide covers the agricultural exemption.
What goes in it
Liquid starter fertilizer, herbicide and insecticide mixes, and water for the mix. Check anything other than water in our chemical compatibility guide before the first fill; the entries for urea solution, calcium chloride and magnesium chloride are the ones applicator buyers ask about most. Liquids heavier than 1.5 times water need a heavier rated tank. Keep the contents under 120 F, which matters for a white tank in the sun on a long day. Rinse the tank and the outlet after a chemical run so the next load does not carry the last one. For the volume, the tank sizing calculator and tank sizing guide are the place to start.
Openings and fittings
- Outlet. A 3/4 inch polypropylene female NPT bulkhead fitting, factory installed. Most applicator pumps and metering systems plumb to this size directly; a 3/4 inch ball valve at the tank lets you isolate one side of a pair.
- Lid. A 5 inch threaded vented lid on top, sized for a fill hose and a chemical jug. The vent lets air in as the pump draws down.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the outlet position, the lid position and the saddle profile for bracket planning.

One size up in the same shape: the 85 gallon applicator saddle tank. For a metered chemical feed rather than a saddle mount, the 65 gallon chemical injection tank is the neighbour buyers compare it with.
Shipping and receiving
The tank ships LTL from Norwesco's Sheldon, Iowa or Lancaster, Ohio plant, 44 by 23 by 26 inches and 25 lb. The listed price is before freight; the freight cost estimator gives the cost to your ZIP, and a pair on one order travels together for little more than one. At the tailgate, check the part number against 44237, look at the saddle face for transit damage, and fill with water the first time before it carries chemical.
