- Model 800 Series - PTO Dynamometer



The Nebraska 800 PTO Dynamometer is a four drum friction brake that is supplied via hydraulic pressure by a chain driven hydraulic pump. When the Power Take Off is engaged, the hydraulic pump circulates the hydraulic oil through the manual flow control valve allowing the end user to fine tune the hydraulic pressure to the internal brake system. The torque reaction is measured by a torque arm that is attached to the back input shaft of the internal load unit. The heat that is created in this process is dissipated and carried out of the internal top tank by an incoming water source. In order to keep the internal brake’s synthetic oil in normal operating condition, the water temperature must not exceed 140 Degree F.  When the end user is finished applying load to the application they are testing, the end user simply backs off the fine tune valve on top and opens the bottom course valve to relieve all pressure to the brake.

The first NEB 800 was designed and manufactured in 2005. Since then, thousands of NEB 800’s have been sold and field tested with zero warranty claims. The Nebraska 800 is today’s largest capacity, field tested, modern dynamometer in this world’s Agricultural market.
