this is on my jd la 145 48 inch deck started making a rushing sound like mabe the spindle bearings going out ,so this year I totally rebuilt the deck due to rust installed new bearings on spindle upper and lower ( tightened them with an impact wrench), all idler pulleys turn freely started it up same sound so I replace pto clutch with an Extreme power sports clutch, same sound clutch works nice. any ideas maybe spindles to tight i don't know?
