Hello everyone, this is my first post to the forum. I bought a JD 2150 a few months ago but have not used it much at all. I changed the oil, fuel filter, flushed the coolant and added SCAs. I have not gotten around to changing the hyd fluid.
When I start it and run it over 1250-1300 RPM I begin to hear a loud tapping/ticking/vibration type noise that seems to be coming from the front hydraulic pump. It resonates in the hyd fluid supply lines and running down the right side of the tractor and when touching those lines I can feel the resonant vibrations. When I go back to idle, it stops. I let the tractor idle for 20 minutes to warm it up thinking maybe its a cold fluid type issue but that did not seem to affect it. The noise is consistent and constant above 1250-1300 RPMs. The noise is present no matter what configuration...ie lift up/down, pto engaged, steering wheel turned left/right. Everything seems to work fine, power steering, 3ph, brakes and pto. The hyd fluid level looks fine as well, maybe on the lower end of the range on the dispstick.
Here is a youtube link to a video I took... John Deere 2150 Hydraulic Tapping Ticking Vibration Noise - YouTube
Any ideas on where to start?
I thought about changing the fluid/filter and cleaning all of the screens but don't want to throw new fluid in if there is something more major going on and I'll have to drain it all out anyway.
I got a good deal on and flail mower and am supposed to go pick it up on Monday, however am planning to test it out with my tractor. Trying to decide if I can get away with a short test of the mower without doing damage to my tractor.
Any advice would be much appreciated.
