Hey Guys,
Got a used MX6 the other day -- it's a 2009, in decent/good shape. Checked the gear box, seemed dry so filled with new oil. Haven't flipped the cutter up to look under at the blades yet.
Last night when I got it, I engaged it around 2000 RPM with my John Deere 3520 tractor; it engaged fine, had some vibration until I got it up to speed, but mowed good. Couldn't hear anything weird from within the cab.
Today I stood outside the cab and engaged it around 1500 RPM and it made some weird noise.. almost a grinding noise for a few seconds until the tractor recouped from the RPM loss. It didn't sound like it was coming from the slip clutch or gearbox on the cutter; sounded like it was coming from the engine bay of the tractor.
Any ideas? Just because it's such a big cutter for the 3520? It doesn't do it once it's already turning; just that initial jump from no-movement, to engaged. If I feather the engagement with the PTO switch, it's doesn't do it. Engaging over 2000 RPM makes for a lot longer and louder noise... only did that once :thumbdown:
I'm assuming right now that it's normal since the cutter is at or over the high end for what this tractor is capable. Just don't want to tear anything up; or would like to figure out if anyone else has the same issue and what they do to lessen the strain upon initial engagement.
