Hydro Whine

[tommyg 152]

I'm sure this has been addressed before. I've been hauling around a trailer full of gravel around my yard quite a bit over last couple of weeks with my D180. No problems moving it around, but when I'm climbing a hill, or moving it from a stopped position, The hydro complains by whining as they typically do, but more  so because of the strain. My question is... Is this just something I should expect from a hydro system? If I'm running the tractor full throttle or close to it, do I run the risk of blowing something out if I push to hard? Will I stall the engine like a geared tranny?

 

I don't want to break anything, but maybe I'm babying it too much.

Hydros whine.  Doubtful you will ever stall the motor, the wheels will slip first.  Hard pulling will raise the hydro temp thinning the oil which may exacerbate the whine noise.  If the fluid is clean and not too overheated you really won't damage anything by working it hard. Do you have a temp guage on your unit.)  However do not go forward to reverse with out coming to a full stop  and don't make jack rabbit starts/stops.  Some years D series had a buffer valve to lessen the effects of that kind of abuse.

I was wondering this as well for my Ford LGT165.

 

It has the eaton 1100 hydro coupled to a 2 speed transmission (I wish my 520's has the low range).

 

The Ford has a lot of whine. I have used both ATF and UTF in it with little change. Tractor works fine and actually quietens down when it warms up.

 

The 520's are very quiet and use 10W30 oil. Can I use 10W30 in the Ford ?

I would not recommend changing oil types as it is nearly impossible to get all the oil out. 

 

Hydro's whine it's just there way like some people I know.

Don't reallyl notice anything when I'm just mowing or doing light duty work. I've been hauling a trailer around the yard with a ton and a half of slag. More than I've ever called on the tractor to pull. Does it with ease. Just notice that whine a lot more under the heavy load and didn't want to blow anything out. Guess maybe I'm just being too cautious. I'd whine too if I had to lug a ton and a half of slag!

I do have a temp gauge. Temp is not a problem. I believe mine does have the buffer valve if you're referring to the rectangular box right behind the right rear wheel.

A little cheese should help. Sorry,I couldn't resist

That is the buffer I mentioned.  if it isn't overheating I wouldn't worry too much about it.  May want to change the tranny fluid and filter more often. (I do not usually use synthetics but if you are going to be doing this heavy hauling for an extended period it might be a good idea.
