I have two new dozers on demo. One is new JD 650K, 128" blade, LGP 28" pads. The cab is super loud (hydraulic wine type noises), I have to decelerate to idle to talk on the phone. Is this normal? This is too nice a machine to have a cab this loud. Using a phone app, at WOT the deere averages 83db. The komatsu phone app reads 78.6db average. To the ear, the difference is very significant. Deere is supposed to come take a look at it and make sure its okay.
