Snyder Industries 225 Gallon Plastic Horizontal Leg Tank

The pad, the deck and the pallet jack: where a 225 actually sits

Where this tank sits is the first decision and it is a heavier decision than on the 125s, because a full 225 is better than nine hundred pounds of water and up to 3,565 pounds of contents at the rating. On a pickup that is a serious payload question rather than a detail: put it forward against the bulkhead so the load is over the axle, check what the vehicle is actually rated to carry, and accept that a half-ton truck with a full 225 in the back has spent most of what it has. On a flat-deck trailer or a skid it is comfortable, and that is where most of them live: bolted through the legs to the deck, with a pump and a hose reel mounted beside rather than on top. On a shop or barn floor it is a standing supply with a footprint close to a pallet, so it can be moved on a pallet jack while empty and drawn from by gravity where it stands. The 42 inch height is what makes that last case work: it is tall enough to get a pail under the outlet and low enough to fill through the lid without a ladder. Under it, level and continuous is what matters. Legs are bearing surfaces, not stilts: they carry through the whole flat foot onto whatever they are resting on, so a bed rib, a raised lip, a broken deck board or a hollow in a slab becomes the new bearing point for the whole load. Plywood or a mat on a ribbed deck, and a flat pour where it stands on concrete; the framework for getting a slab right under a standing tank is in the concrete pad sizing guide and it scales down to a footprint this size. Then plan for the surge: 225 gallons in a 52 inch body pushes hard fore and aft under braking, worst at part-full, so restrain it in both directions through the legs. Where a leg or applicator tank goes on the road, how it is classified and what an agricultural exemption covers is set out in the applicator and leg tank classification guide. Run 225 gallons against your actual draw in the tank sizing calculator and take the reserve and freeboard from the tank sizing guide.

The 225 and the 230: two capacities in one footprint

Two part numbers on this sheet sit on the same 52 by 38 inch rectangle, and the sheet's own figures are the honest way to choose between them. This tank is 42 inches tall, 225 gallons, and listed at 85 pounds empty. The SII-1280000C26 is one inch taller at 43 inches, holds 230 gallons, and is listed at 68 pounds. So the sheet gives the larger tank as the lighter one, and we print what it says rather than explaining a difference the sheet does not explain. What that leaves you with is a real choice on two grounds. Height: if the mount has a cover, a rack, a mirror line or a doorway with an inch of margin in it, this is the tank that clears and the 230 is the one that does not. Lid: this tank carries the 6 inch threaded vented lid, which is the smaller opening in this family and the one less likely to be caught on anything in transit, while the taller tank carries a 10 inch lid and is easier to reach into for cleaning. Below both, the SII-1003600C26 is the compact 125 at 44 by 32 by 35 inches for a deck that cannot take this footprint at all, and its weight is listed at the same 85 pounds as this larger tank, which is another figure the sheet gives without comment. Pick the footprint, then the height, then the lid, and the part number falls out of it.

One and a quarter inches of outlet against 1,876 pounds of water

• Outlet: a 1.25 inch outlet, as the sheet lists it, at the low end of the body. It is the same port the 125 gallon tanks carry, which means a 225 takes proportionally longer to empty through it: it is a good match to a hose line, a spray boom or a transfer pump, and it is not a dump port. If speed of emptying is the job, say so at order and we will talk about the larger tanks in this family and the outlets they carry.
• Draining it dry: with 42 inches of body the last inches sit across a broad floor, so a level deck leaves a residue and a deck tilted toward the outlet does not. On a trailer, park nose-up with the outlet at the back; on a skid, shim the far end.
• Valve and first joint: a shut-off valve at the outlet, supported off the deck rather than off the tank, and a flexible connector before any rigid pipe. With 1,876 pounds of water in a body this long, the loads that reach the fitting under braking are real.
• No inlet on this sheet, so none is asserted: filling is through the 6 inch threaded vented lid, hose down inside the body.
• Access: a 6 inch threaded vented lid. Small enough to stay out of trouble, big enough for a fill hose and a light. Keep the vent clear, because a tank drawn on hard through a blocked vent will deform, and a 225 has more wall to lose than a 125.
• Service limit: 120 F / 48 C, with a 3 year warranty as the sheet gives it.

Give us the liquid at order and the fitting, the gasket and the valve get matched to it. For blended fertilizer solutions the thing to watch is not the tank but the blend: a horizontal body is wide and shallow, which is the geometry that lets a blend settle into layers and a spreader run off spec, and the fertilizer blend stratification guide covers both the physics and the field checks that catch it. Where it freezes, drain the outlet, valve and hose and leave the body; ice on the surface of a polyethylene tank is not the problem, a plastic valve full of it is. One habit worth building: look under the tank at the legs and the deck every time you fill it. The legs carry everything, they are the part nobody inspects, and a worn leg on a mobile tank is the warning you get before a mount fails.

Fertilizer solution, fluid feed and shop dispensing at drum-replacement scale

Two hundred and twenty-five gallons is the size where a leg tank starts replacing a stack of drums rather than a few jugs. The work it does: a nurse supply on a trailer that keeps a sprayer going through a field without a trip to the yard; starter fertilizer or fluid feed carried to a planter or a side-dress bar; water hauled to livestock, a remote building or a planting crew in quantity; wash-down and dust control water on a construction, utility or landscape truck; a gravity-fed standing supply of a shop fluid where the 42 inch height puts the outlet above a pail; de-icing brine on a contractor or municipal rig; a mix station feed tank in a yard, filled by a bulk delivery and drawn down through the week. In all of those the tank stands on its own legs, which is the whole point of the shape: no stand to buy, no cradle to fabricate, no saddle to align. Two limits worth stating plainly. This is a single-wall tank with no containment of any kind, so if the site rules say the liquid has to be contained, this is not the product and the contained alternative is a different build. And the sheet's 120 F / 48 C service limit applies to the liquid and to the tank sitting in the sun, which on a dark deck in July is not a theoretical number. Beyond that, what ends a tank this size early is the mount: over-the-body straps instead of through-leg anchors, rigid pipe bolted to the outlet, or a part-full load driven fast.

Out of Marked Tree at 85 pounds empty

The SII-1003900C26 is molded at Marked Tree, Arkansas and moves as freight at class LTL as the sheet lists it, at 52 by 38 by 42 inches, 85 pounds empty and 85 pounds to ship. The freight cost estimator prices the lane to your ZIP, and the listed price is before freight. Eighty-five pounds is a two-person lift off a pallet and a one-person injury, so plan who is taking it off before the truck arrives, and tell us at order whether there is a dock or a forklift, because a 52 inch pallet at a residential or field address is a curbside drop. Do not drag it on its legs; they are bearing feet and they scuff. Have the mount ready first: the anchor points, the plywood or mat, the straps, and the pad if it is standing on concrete. Then water-test it in place before the first working load, fill to the lid, let it stand, drive it slowly if it is mobile, and look at the legs, the deck, the outlet and the lid seal afterwards. Write the tank's part number and its outlet size on the vehicle's maintenance sheet the day it goes on, because the part you will need in a hurry is the one nobody wrote down. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
