Hi. I have a Toro Greensmaster 3150, been a very good mower considering it has 5200 hrs on it and its 3 years old. Any way ran into a problem in the hydraulic valve body. Reels will lower and turn on, after about 4 passes the reels still lower but the reel speed is not up to par. If I turn the reel speed vavle to the slowest setting while the reels are engagde then turn the vavle to its highest setting(normal mow speed) the reels come back to life. I'm thinking it may be the spindle vavle in the reel curcit but not too sure. I have ohm tested the coil pack and it is in spec. Any thoughts? Buy the way, great site!
