LS 180 - Hydraulic Problem - Motor Dies

jack rabbit · Mar 13, 2014

Put new hydraulic pump on. Washed out all hoses & hydraulic tank, put in new filters and fluid. Ran the tractor on job 4 weeks and now the hydraulic charge light is coming on and the motor dies. Tractor. Will start back up and the hydraulics all work well. Could it be the sending unit at the filter? Thanks

Replace the hydrostat charge pressure sending unit. Lift the seat and look at the hydrostat pump on your right, the one with the hydraulic pump. On top of the hydrostat pump you have the two large hydraulic hoses and two steel lines. The steel line closest to you has a tee fitting at the hydrostat pump and a small hose is attached to the fitting. Follow the hose until you find the sender. The system will kill the engine after about 30 seconds if it fails to see either engine oil pressure or hydrostat charge pressure. Common problem.
