Read your owners manual, Mine I run at least 1800 rpm

Hydros do whine. I can here my neighbors JD hydro whine and he is 300 yards away. On my loader I run just enough RPMS to work the loader smoothly. About 1800 RPM on my tractor.

Some HST's whine like a banshee and others are quite. New machine may quiet down some with a few hours on the clock but No real definite answer. Engine RPM probably minimum of around 1500. I would suspect most people runs theirs between 1800 - 2500 RPM.

I think the brands whine differently. The neighbors JD has a high pitched whine. My Kubota has a whine just as loud but it is a lower pitch.

well i'm going to ask that question have you checked the fluid level. i know it's new and it just came from dealler but that don't mean it's got the proper amount of fluid in it.

 

[djp1218]

so you think about 1800 is in the ballpark? I guess im just going to have to play with it to find the right mix of throttle and ranges I also read on this site that colder weather makes it whine louder its about 30 today and yesterday when it was delivered it was 28 along with 65mph on the highway it was probably pretty stiff oil was also wondering if you check the hydro oil with it running like you would on a car?

 

[djp1218]

yes with the engine off it only reads a little bit on the stick with it running warmed up i cant really tell its clear

 

[whistlepig]

Mine does whine louder when it's cold outside until the fluid gets warmed up. On the FEL RPM's my FEL will run sluggish if the RPM's are too slow. If the RPM's are to high the FEL runs kind of jerky. 1800 works best for me.

not sure on that make but i would not think so, your manual will tell you

2000 RPM on my B26 is a sweet spot; plenty of power and operating speed and yet the engine isn't screaming like it does at WOT (2600 rpm)

My B 26 does whine and much louder than my BIL's New Holland. I am thinking seriously of trying to find some SUDT2 or other synthetic to see if it quietens it down a bit. This as soon as I get my RV setting stabilized

the manual really doesnt say it just says check it when its warmed up and i have heard that if you use a thinner oil it pretty much stops it but i want to use whats best for the tractor and not my ears is it safe to use a thinner oil? also how fast should the peddle come back up it comes back up kinda slow im used to using my buddies case 580 gear so this is all new to me

The tractor should stop immediately when your foot comes off the hydro pedal.

 

[djp1218]

yes it does stop but the peddle slowly returns is that normal?

 

[sam5570]

as long as your sure the fluid level is correct the warmer it get's will quiten it some but not alot and no i would not use a thinner oil because of the tempature.

 

[whistlepig]

It would be something I would be concerned about. If the pedal doesn't freely return to the center position it may want to cause the tractor to creep down the road. I'm sure it's nothing major. Maybe it needs a shot of grease or a better return spring.

 

[djp1218]

i will have to ask the dealer if it should be running or not when checking the oil if it doesnt need to be running then i would have to say its low it barely touches the stick and with it running it seems to be splashed over the whole thing

 

[djp1218]

that does seem like what it could be its a leftover 2011 its been sitting for a long time its kinda hard to push down also i will put some grease to it in the am its got a spongey feel to it thats the best way that i can explain it
