Most new owners(including me) don't realize that"with the HST,less pedal means more power" let up and it gears down,more power less speed.Only use of High range should be on the road.I took me a year to realize this!
I also have an L3200.
It is much louder than my B7510.
The worst whine is when the tractor is yelling at you.
It usually means the parking brake is on ! I keep forgetting it all of the time and she is very unhappy when you try to drive like that.
The HST is loud normally especially if it is your first one.
I wish i could TAZER myself if I try to drive with the brake on:mur:
Cheers,
