Yeah on the tractors, if you hear additional whine when operating the hydraulics under load, crank up the idle even if you need to get upto the min pto rpms, get more flow going. Always got to get a feel/hear for that sweet spot of the rpms and performance.
I wear earplugs in my cab skidsteer, lol with the radio playing, lol, but the hydraulic whine will make your ears ring after spending a day in it without any protection.
I want to buy better hearing protection, something more comfortable that I can use also when mowing and with the trimmer. Something with a radio wouldn't be a bad idea but then again..don't mind hearing the smooth sound of the diesel either, it's better than year a zero turn's mowing deck for 4 hours lol. It almost makes me fall asleep. I like over the ear stuff, I don't like things inside my ear that's why I have these Shokz wireless headphones, they're awesome but don't block any sound which is what I use when I go for my runs.
I've used the tractor without hearing protection a little bit, its not TERRIBLE but I wouldn't use it long. It's really weird though because others say the tractor is really loud and I can hear them talking over the tractor's engine but they can't hear me talk. It's almost as if the tractor is more quiet when in the operator station versus outside the tractor.
Yeah...I'm just not used to the hydraulic flow and the correlation with the engine speed. On my lawn mowers, I just always set it full speed because I want the blades spinning the fastest for a nice cut. But diesels are way different really. Like it doesn't
always need to be at full speed. Like I use low idle when trying to line up for the ssqa stuff or when backing into the garage lol.
