Progress Show goers keen to get look at giant fertilizer cart

REGINA — What is likely the world’s largest liquid fertilizer cart attracted a lot of farmer interest at Canada’s Farm Progress Show in Regina last week.

“I’ve checked around and there isn’t anything this big on a single frame,” said company owner Wade Mowat of CW Mowat Manufacturing.

The FLC 9000 ST Super Series is a quad tank, quad track, single frame 9,000 gallon liquid fertilizer cart.

“I’m totally flexible on how it gets configured.” Mowat said. “I don’t build one cart the same as the next. Everyone seems to be a little bit different, because everybody wants a little bit different configuration.”

Mowat built this cart, which costs $158,000, for a customer from east of Regina

“This is going behind a Seed Hawk toolbar. Behind the toolbar is a Morris 650 bushel air cart, and then this is going to go behind that,” he said.

Built of 10-by-six inch steel beams, with half-inch wall thickness, the machine from New Norway, Alta., is no lightweight.

“We had to go to the heaver thickness to carry for the span. Normally, if it’s a smaller cart, the thickness of the wall would be a little bit thinner for lighter weights, but we had to go to this for the weight capacity,” Mowat said.

The cart comes with a three-inch, Honda-powered pump, which pushes fluid into the tank from the bottom. Each tank comes with a shut down switch that helps avoid spillage. The heart of the cart is the ball and socket assembly that is fabricated from a solid piece of 4140 steel.

“We take the parts and get them liquid nitrated for extra strength and wear-ability. Then we seal them with a rubber seal to keep the dust out for long service life,” he said.

The cart can be configured with tracks or tires of all different sizes.

“Depending on the size of tires or tracks they decide to go with, we’ll move the rear axel forward or back to balance the cart so that all tires or tracks have the same weight, or not.” Mowat said.

With the tracked configuration, using Elmer’s Manufacturing transfer tracks, Mowat said they achieve slightly less than seven pounds per square inch of ground pressure.

The fittings on the cart are Banjo manifold fittings, and the hoses are built for liquid fertilizer and are rated for up to 150 pounds pressure.

On this cart there are two separate liquid fertilizers streams possible, each with their own hydraulically driven pump. The three back tanks are connected in one stream and are for nitrogen.

“The front tank is connected with a separate hydraulic drive pump, and that’s for the phosphorus, or Alpine, or any sort of starter fertilizer,” he said.

Mowat uses Ace pumps and motors that range between four and six gallons of oil per minute.

“Typically you’re going to be closer to four than to six because you are usually running the capacity of the pump from 60 to 70 percent,” he said.

Hydraulic drive is the most common configuration but some customers have used ground drive to power the hydraulic pumps.

“If anyone has a limited amount of hydraulic capacity in their tractor, a ground-drive pump can be added. Elmer’s transfer tracks have a kit that you can add to them that have a output shaft so you can drive a mechanical pump.”
