A high/good grade of 20-50 engine oil.....if you lift up the seat, there will be a sticker that says that.....if the sticker is still there!Hi all, i just purchased a FERRIS IS 700Z ... WHAT VISCOSITY AND BRAND OF OIL DO YOU USE IN TH HYDRO GEARS? In addition, is it synthetic?
A 9.0 cst oil is a SAE20 to SAE30 at 100C temp.This is what Hydro-Gear calls for:
"Typically, an engine oil with a minimum rating
of 9.0 cSt (55 SUS) at 230° F (110° C) and an
API classification of SL is recommended. A
20W50 engine oil has been selected for use
by the factory and is recommended for normal
operating procedures"
Hydro-gear also chooses Castrol as the brand they use.
What is in your mower has to do with what Ferris decided to put in it after they received the units.
Hydrogear units get the Hydrogear branded 20w50 oil unless the mower manufacturer recommends something else. Some call for 10w30, some 10w40, some 20w20 hydraulic oil. Tufft-torg get the recommended 5w50 tuff-torq branded synthetic oil. A few even use their own branded oil with no cross reference like the oil recommended in some IH cub cadet transmissions. JD get the hy-gard Low vis for the unit that use that oil.Did they say with a straight face that the "traditional" oil does not sheer down to something less than the required minimum 120 celsius viscosity over the 400 hour service interval?
Or deteriorate in other ways? Does anybody here believe that the traditional oils are "just as good" as the high end synthetics?
I could do an UOA at the end of 400 hours with a traditional hydro oil to prove this, but that means I would have to take a risk on the longevity of my hydros to prove this point.
It is not worth it to me. If I only expected to get 5-10 years out of my Hydros, maybe it would not matter. I would like to get 20 years, if I live that long.
It makes more sense to me to err by being extra cautious and use the synthetic recommended by the makers of my mower .
It is relatively little extra money over the life of the hydros, for my peace of mind.
ILENGINE, let me ask you this: Do you follow your own advice? What fluid do You run in your Hydros?
Viscosity cst is rated at 100C or 212F. Hydrogear is confusing the situation by using some non-standard recommendation.Slomo, note that Hydrogear lists the cSt at 120 celsius. At 100, this would translate to a higher cSt, so
you cannot directly compare the @100 and @120 values. It is a high shear, high temperature application.
Hydros may run as high as 150 celsius, so the heavy, high viscosity 20w50 motor oil they call out is actually required.
Going to an even higher viscosity such as somethingw60 would sacrifice cooling efficiency.
They recommend motor oil instead of the even higher viscosity gear oil, because of the typically high temp environment.
(Gear oil could be something like 75w90)
Hydrogear doesn't make the SAE classifications. Don't care what they list. Why can't they list some cst at 100C like the SAE rating?Slomo, note that Hydrogear lists the cSt at 120 celsius. At 100, this would translate to a higher cSt, so
you cannot directly compare the @100 and @120 values. It is a high shear, high temperature application.

Hey! Don't go hating on Motor Honey. Back in the early 70's i had a 352 Ford galaxie that burned oil like no other. 3 quarts of SAE50 wt and 2 quarts of Motor Honey and it didn't smoke a bit. Sold it like that.As long as you are using Motor Honey you are good LOL.

Never fails. Just remember "My oil is better than your oil."?Let's have a great vicious "oil thread"!!!
Just saying the "standard" for kin viscos is 100C. End of message. Sure oil will thin a bit more if it gets hotter. We all know that. Use 200C if you like.My point was, the Hydro manufacturer Hydrogear and multiple Zt manufacturers (those who use the Zt Hydros)
seem to all recommend 15W50 or 20W50 motor oil. This recommendation makes sense to me on multiple
levels, so I follow it.
Kinematic viscosity can be measured at any temperature the manufacturer choses.
100 celsius is merely one popular reference point often given, so is 40 celsius, so is 150 celsius.
AFAIK Listing it at 110 or 120 celsius is not forbidden.
Slomo, do you have an alternative recommendation? Let's hear it!
Shearing is simple. Oil molecules getting smaller from some process. Just leave it at that. Trust me, oil or let's call it a fluid in a hydro system has a leisure life compared to a fluid in a gearbox. Noted most mowers don't have gearboxes as we all know.HTHS? That may not be a bad idea. If the fluid is supposed to stand up to high heat and high (molecular) shear, car manufacturers tend to spec the required min HTHS.
If you will, it is a more "modern" oil spec. developed to quantify how the oil behaves in such environment.
Slomo, you could perhaps initiate a conversation with the manufacturer, and find out more about their reasoning, or induce them to change their ways, or at least explain
why they decided to spec what they did. https://www.hydro-gear.com/end-users ... I see no point in yelling at BITOG users, because of what Hydro-gear decides to publish.
You posted earlier " Don't know about high sheer at all. Nothing is sheering".
The sear here is molecular shear. When you push oil through tight spaces at high pressure, some of the friction modifier's long chains get chopped off
i.e. "sheared" resulting in undesirable viscosity changes. BITOG has an excellent article that explains the topic in some detail.

I think they reccomend it because it is readily available. What about using 20-50 motorcycle oil which is high in zinc and phos.??Slomo, note that Hydrogear lists the cSt at 120 celsius. At 100, this would translate to a higher cSt, so

So I have yet to encounter a shop in my area that I would do business with. I guess it's the way I came up with respect to working on cars. I was taught by folks that one might call extremists from a very early age. I was putting cars on lifts at 8 years old, lol, which now that I think about it was a little insane but the guys teaching me knew where I was and when. I installed a car stereo in my mom's car at age 6 all because I watched someone do it that explained everything to me as they went. At age 7 my mom's car wouldn't start one winter morning, so she called my uncle down the block. She told him I was outside under the hood. He said "Give him a minute". I propped the choke flap open with a screwdriver and started it right up. I was also taught to wipe down my tools every day, and put them back in the box where they belong. Then wipe down any work areas because grease doesn't evaporate. I briefly worked in the field and realized there just wasn't enough money in it. So I moved on. But I still practice the same things I was taught, and unfortunately that created expectations from others that often just aren't there. So when I visited the local shops it was mostly walking in, looking around, and running like hell. Either I'd see a complete mess, low end consumables in the shop destined for customer machines, or just general disarray.Actually it is good to know for us shop owners that prefer the synthetics over conventional oils as the synthetics have higher operating temperatures and low breakdown rates. But of every equipment OEM will use the cheapest oil they can get by with. Nearly every Tuff Torq here has 20W50 conventional oil in them until I go inside one then they get the Tuff Torq premium 15W50 Synthetic installed.
Plus with our Summer temps rising every year lately we need to adjust our type of oil usage.
Well, I tried to dress it up as best I could for an online forum. Because saying things like "Halfwit sixth grade dropouts with a drawer in their toolbox dedicated to various low-end narcotics" would have been a little impolite, and probably too spot on for most people's tastes. But hey, I never was all that great at keeping my observations to myself. Ya got me. I just don't have any respect for MOST people that do this work professionally. But the better folks are definitely the exception to one hell of a sad rule. Hell when I called the Ferris support department some weeks ago I ALMOST ASKED the guy that answered if his middle name was Gomer. But hey, it was either say "SHAZAM SHAZAM" and hang up, or keep the warranty going as long as possible. We all have difficult choices to make.That means I prefer to just deal the locals when it comes to repairs and not have a lot folks just wasting my time. Here on Pluto I don't get much in the line of out of the area visitors. I do have one fellow tech out Huntsville that use to come by for technical help but I haven't seen him in a long time so I can assume doing fine on his own now.
Plus my shop is a mess in more than one way. I got young chickens staying in it until they are old enough to join the grown ones. I just don't know how the hen survived three week out in the open sitting on the eggs. She hid out on me. I just lost three chickens in the roost because of a raccoon breaking into the building. One of them was my biggest pet rooster which I had to finish killing the next morning. Not a task I wanted to do but it was necessary to prevent a horrible suffering death.
Plus nearly all my work is outdoors as I use my shop for tools and parts storage. I even got parts stored in my house right now due a failed storage room. Some idiot put the tin roof on it backwards and I didn't know it when I brought the place so it has ruin the whole area as the attic was insulated. A complete rebuild is in order but I be going back with blocks, concrete floor; but the same type roof, just this time I do it myself. Getting a little rough at 62 as I slowed down a little now.
Strange though that I have one customer from Florence coming to the shop. Apparently no good shop over there either. Now that is nearly 60+ miles away but he got farm work in my area so he just comes when he is in the area.
As for taking care of your tools it is important as if you make your living with them they be in good shape and you know where they are hiding. It not fun when you got to hunt down your tools especially the custom ones. The main thing is don't loan your tools out as it is usually the very ones you need for the next job and they have a bad habit of not coming back.
As for getting weekends off I don't get much off either that is why my yard looks like a hay field as I only got Sundays off and there is a lot to get done even when it is raining. I ended up having to soup up my mower so I can cut the tall grass. 42 cut with a 21 hp (was a 16.5 hp) and upgrade the deck belt from a 1/2 to 5/8 belt. Just keep burning up the 1/2 belts. But at least just goes through about anything I throw at it now.
When I was in college we would spend an hour to mount & polish a near perfect microscope specimenSo I have yet to encounter a shop in my area that I would do business with.

YOU sound like you have a shop I'd love to send my equipment to, so I can do others things. Sure enough, all I see for you is "Torland". My guess and luck probably means that's Scotland, but I know for sure it's unfortunately nowhere near here. That's too bad. I'm never gonna get a weekend off, lol.
