Holthaus also built a 2510DH for his neighbor, who has used it for 4,800 acres of custom work this fall. Dual-placement offers some advantages, Holthaus says. "We are dropping the dry fertilizer in the ground behind the anhydrous ammonia," he explains. "It saves you a pass." It also helps the plant. "It's nice to have the fertilizer in the ground. It makes it readily available to the plant."
Traverses terraces with ease
Besides being low-disturbance and offering dual-placement, the applicator and cart are easy to traverse over terraces and rolling terrain, which prevents overlapping, saving time and money, he says. One of the features includes wheels that dolly. In most fields, fertilizer is applied in straight A-B rows. "Backing up the tank is easy, because it doesn't pivot," Holthaus explains. The wheels move vertically. "When you go over a terrace, one of [the wheels] has got to come up." The addition of the wheels in the center helps maintain balance. "With this, it stays more level, because the tires are closer together."
Aside from being rust-resistant, the stainless-steel bottomed Montag tank along with the 2510DH cart is also designed for moving over terraces. "The tank has a low center of gravity," Holthaus says. Because it's mounted on top of the wheels, it also provides stability. "There is no extra added weight to the bar," he says. Weight is added to the tongue instead. "A little bit of tongue weight is good," he explains. "It gives the tractor more traction."
Holthaus can build a cart in about ten days, but would like to make an arrangement with a fabrication shop to move to small batch production. This way, it might take a week to build ten. He is currently taking orders for fall production run. "They like to order tanks 120 days out," he says. "We want to build these for fall application."
