Bought a brand new 1025..noticed when machine is hot,hearing a very high pitched whine...this was with plow attached.Put loader on to move huge snowpiles from blizzard & noticed strange sucking noise in joystick in mostly down position..Talked to dealer & they thought might have air in system.Said to start tractor,idle up & move pedals like 8-10 times,turn tractor off,& move joystick around,should bleed system.Tried this & still have sucking noise when moving loader joystick down..dont hear the whine when machine is cold,seems to be when it warms up..fluid level was ok..but did notice a little bit of white kind of paste on bottom of the fill plug which in my experience would indicate moisture.I saw somewhere on this site..somoene suggested running pto?..I am very frustrated as i just spent 20 k & the machine has 8hrs on it..hoping easy fix so i dont have to have dealer pick up next week!..suggestions are appreciated

Yup, definitely normal to hear distinct fluid flow noise when lowering the loader.

OK, need a little more info.

Was the high pitched whine occurring with just engine running without functioning any hydraulic attachment, I.e. tractor was sitting still not moving and SCV was centered, or was the whine occurring when you were actually functioning an attachment.

When you say plow, I assume you mean the front blade, not a 3 point attached garden plow, correct?

Since it is hard to determine what the noise is coming from, I will offer these simple thoughts<<<<
1. When propelling the tractor forward or reverse, the propel hydraulic system will whine, especially when in high range and/or when working the tractor like plowing snow.
2. If you are lifting with the FEL or moving any hydraulic attachment cylinder, when the cylinder bottoms out, you will here a whine. This is normal. This is caused by hydraulic oil flowing over the relief.
3. If you are working a hydraulic accessory close to its capacity, the hydraulic system will whine because it is working at higher pressure.
4. Concerning what you are referring to as a sucking noise, I assume this is the oil flowing through the lowering orifice. This is really not a sucking noise, it is the oil be forced through the orifice.
5. Be sure all the attachment quick connects are connected completely. Sometimes they are difficult to get coupled correctly.

Yes, the white residue on the bottom of the fill plug is moisture. Not much you can do about it other than, when running the tractor, get the hydraulic system up to operating temperature. This will help with moisture build up.

I do not believe the problem is air in the system since an open center hydraulic system will automatically take care of any air.

Since the tractor only has 8 hours on it, I doubt you have a hydraulic pump cavitation problem since the hydraulic oil hasn't been changed yet. Pump cavitation will cause a whining sound at the hydraulic pump because the pump is sucking air in the suction line. This would be caused from loose connections at the suction hose that connects the suction strainer to the suction tube at the left rear of the differential.

I doubt what you are hearing is a problem.

Tractor is in neutral..at an idle u can hear it ,turn rpms up & its a very high pitched whine,do not notice it when machine is cold.After 10 min or so,very apparent.By blade i meant 54"quickhitch snow blade.With loader on,im hearing a very pronounced suction sound,when moving joystick in down position only,wont do it in float or just gently pushing it but a certain position with joystick im getting a kind of squeel-suction sound in hydraulics.Not sure if the 2 noises are related?,normal?,seems excessive!..been around tractors my whole life & not quite sure whats going on but i think theres an issue with something.Dealer offered to pick it up next week but if its how these machines are i hate to waste there time & mine!

I was going to suggest lowering the 3 point also. It sounds like the 3 point feed back linkage rod is out of adjustment.

Has the tractor made this noise from new?

Just curious but did the dealer install a power beyond or anything? From my experience with any hydraulic whining noise it's a hydraulic line contacting something slightly 90% of the time.

The 1025r does make a decent amount of noise related to the hydraulic pumps in my opinion, but if you're worried have someone from the dealership come give it a listen, that's what warranties are for. The suck/squeal, lift the loader, turn off the engine, and see if it makes the same sound. If it does, it's definitely from the reducer in the hose..

No power beyond,just the 54"quickhitch plow,h120 loader & 54 auto connect which i wont be able to use till probly july with the 3ft of snow we have around here!..I will try lowering loader tomorrow with engine off..& i figured i will stop by dealer monday & listen to another 1025 .We checked one thursday,& there was no hydro noise..but it also ran only about 2 minutes.My old 3 series had that classic hydro noise when moving & if you didnt know them you would think something was wrong,but that was just the way they were!

The suction screen in the bottom of the transmission is plugged causing cavitation of the oil and starving the pump. Mine did this at 14 hrs. Dealer picked up the tractor and changed the screen and oil and all has been good since. Now have 65 hrs.
My steering was difficult and loader cycle times were 30-40 seconds and had white grease like fluid on my filler cap.

With loader on,im hearing a very pronounced suction sound,when moving joystick in down position only,wont do it in float or just gently pushing it but a certain position with joystick im getting a kind of squeel-suction sound in hydraulics.
Sounds normal to me. My 2720 makes the same sound. You can hear the sound even more if you raise the loader boom, shut off the engine, and then push the loader SCV all the way forward. The suction sound will be even more pronounced.

I don't think I've ever had anything with hydraulics that didn't make some squealing noises when you made certain movements with it. If it seems to be working normally, no leaks, just use it.

I am really curious as to what plugged the suction screen at 14 hrs? I've pulled many suction screens on ag tractors at 1500 plus hours and not had one plugged yet unless there was a catastrophic failure. Most have had a few plastic shavings or a few pieces of o-rings or seals and that was it. Not saying it wasn't but it would be nice to know what plugged it as I'm considering one of these tractors for myself soon.
