F3990 Power and zerk Fitting

[AllDodge]

Have about 37 hours on my F3990 and the last couple of times mowing, noticed the motor rpms going down a bit. The first time the grass was higher then normal so thought maybe that was it, but next time it was just tick as usual. Looked at the fuel filter and while its not easy to see, it doesn't look bad and can see the filter media inside. Have new filters on the shelf so going to try replacing it for next cut. Wonder if anyone else has had issues with power?

The other thing is the 8MM zerk fitting on the drive shaft fell out. Pick up new one and installed but it didn't take next to no tightening, and it just spun. Thing when the zerk was installed someone stripped it, so figure I will wait until mowing season is over and haul it to the dealer for a fix.

This might have been better in the Lawn and Garden section

Yeah that would be strange for an engine to slow down a bit when engaged into power consumption and the nerve of one zerk being stripped out is horrible and after only using it for 37 hours and it not being as new as it was in the showroom with no use. AWEFUL!!!!! Is it as clean after using it as it was in the showroom? Non of the 3 Fs I've owned have stayed clean after using and abusing them!!!! I've had zero (0) zerks stripped out on over 20 Kubotas I've bought so I guess someone doesn't like you, maybe your dealer.

What is the old saying about best to stay nothing or to speak and remove all doubt.

Have cut the place several times and it didn't even start to slow down on anything, tall grass or climbing the steep hills, nothing phased it. Now it is slowing down and I have to ease up on the pedal. I know diesels, but since this is still under warranty just wondered if others may have had similar issues.
