- In-tank mixing without and moving parts
- The Nuhn front pump system creates a circulation from the rear of the tank to the front. All of the mixing is done at the bottom of the tank so solids and manure do not build up. Other tanks on the market circulate from the top, which allows for solids to build up at the bottom of the tank.
- G-Force tapered bearing and seal system
- The G-Force seal system uses a pressurized grease cup to force grease throughout the enclosed unit. It acts like a wheel hub and purges grease through the one-way seals. Running throughout the unit is a solid 1 3/4″ shaft, rolling in two tapered bearings spaced far apart for strength. The tapered bearings are protected by three lip seals at the liquid manure end of the unit, and two seals and the top end of the unit.
- Pressurized unloading creates even spread from full to empty
- Control valve adjusts spread from light to heavy
- The Nuhn valve cylinder is on the front of the tanker spreader, so it is visible by the operator to know the position of the valve as opposed to where the cylinder is on the top or rear of tank, which is out of sight
- Volume control feature allows for additional attachments and a low spread pattern
- 1000RPM or 540RPM constant velocity PTO
- Most tanks on the market use a standard PTO shaft. If the tractor turns at 45°, the combination of angles in both universal joints must bend an equivalent of 45°. The best geometry is achieved when the distance between the draw pin and the PTO of the tractor is the same as the distance between the draw pin and the shaft of the spreader pump. This gives 22.5° at both ends. When a long power shaft, such as 48” is used, very little bend happens at the spreader end, and the rest is made up at the tractor end. This creates excessive angles, chattering on turns and shortens PTO life. Also, the PTO in the tractor may be damaged.
The Nuhn PTO uses a separate shaft from the pump to a bearing half way out the tongue. The shaft to the tractor is a constant velocity power shaft that has a double joint to maximize angles and reduce or eliminate wear and tear on the drive train.
