Noisy Loader

[Foothill Rancher]

New to posting but been reading for a long time, looking for advise.
I have a L4400 Kubota with 82 hrs, had 50 hr service done a few months back by my dealer, when I got it back I noticed that the loader strained the engine when operating, not much, maybe dropped a 100 rpm or so but the curl up seemed a lot slower to me, I called my dealer and asked if maybe the new UDT may be causing this and he said no that he did'nt think that would be a problem but the other day I saw a post and one of the dealers post that any fluid change could change the feel of the tractor.
Has anyone else had any problems such as this?

Thanks for any info.

Of course any change in your tactors hydraulic oil can change the loaders feel. By change I mean things like oil temp and the oils viscosity. Like if you were running ISO 46 and then refilled with ISO 68, maybe that would change things up a bit.
