T-L's exclusive hydrostatic drive design offers substantial advantages not available on electrically driven systems. Each tower of a T-L system moves continuously delivering uniform water application especially important for chemical distribution. Continuous movement reduces the chances of getting stuck and reduces wear on drive components significantly. T-L's hydrostatic drive design provides maximum torque while automatically adjusting for the varying tower flow requirements determined by the rotation speed. A pressure compensating, variable flow hydraulic pump supplies only the power required, not the maximum 100% of the time. T-L's specially formulated hydraulic fluid, Hydroclear™, is non-toxic, environmentally friendly, superior in lubricating performance, and extends component service life. Hydroclear™, will last the lifetime of the system if the recommended filter changes and service intervals are performed.
