Kubota GR2100 mower deck/PTO

[mpt1123]

Hello:
I'm having problems with the mower deck on my kubota GR2100. It started with the mower engaging/disengaging while mowing. Since I've had the tractor for 11 years I figured it was just an adjustment. I made the adjustment and the mower engages but it doesn't seem to have the power it used to have. It seems to bog down a bit and I'm seeing a little more grass clumping than usual. It seems that the PTO is just not transferring all of the power to the mower deck. Is it possible this is a result of some clutch wear in the transaxle?
Thanks.

Check the tension on the belt for the mower blades.

I'm thinking it may be a clutch problem. The RPM's on the mower deck go up and down while I'm mowing, almost like something is slipping. I'll have to tear it down to take a look at the clutch pack.

PTO clutch failing. There are several TSB's in reference to the GR2100 transmissions, might be worth asking the dealer to pull those TSB's for you.
