deere 726 motor high pitched sound

[Joachim_Mizrahi]

My buddy's 2021 Deere X320 (726 motor, barely used) is already singing like a mosquito at mid throttle. Half to three-quarter speed, machine not even moving, and it's got this sharp high-pitched whine that makes you wonder what corners Deere cut on these newer models.

For a mower with such low hours, it shouldn't sound like something's about to grenade. Dealer will probably just shrug and say "normal," but I can't be the only one who thinks that's BS. Anybody else hearing the same thing on their X320s? Or is this just another case of Deere quality slipping compared to the older machines?

a lot of the newer X3 series have that mid throttle whine. It's the hydrostat pump more than anything failing. Annoying, but you see most dealers call it normal. The older ones were quieter, so you're not imagining the quality drop

Transaxle or hydro whining under light load, and deere tends to call it normal, annoying
