@arrow Can you confirm something for me, please? I initially read in the manual you just need to change the hydraulic filter and replace the lost fluid but watching some videos I see folks changing all the hydraulic fluid out at 50 hours. So now I am a little confused as to what the correct path is, refill vs. replace. It sounds like you replaced yours at 50 hours, is that correct?
Also, you are right what was in the filter was yellow and I replaced it with a Mahindra brand (purple) so now I am thinking I should replace it all because the additives might not match up 100%. Thoughts?
In the meantime, I will look into coastal or make another 2.5-hour trip to get the Mahindra brand again. Grrrr
When i purchased mine, the manual stated to change out the entire fluid @ 50.
I think Mahindra saves money by putting in the cheaper stuff at the factory.
If the intention was indeed this, they covered their butts by saying change it out at 50 and they cover their costs of the initial oil by having the customer pay for the new oil.
You have to be aware of what might be "promotional" tactics of the various manufacturers use to sell their wares.
If one company is stating to change out their oil at 300, 400 or 500 hrs, to remain competitive and as a sales pitch, another company might state the same thing.
In your shoes and since you are in a warmer climate where you do not get sub freezing temps, I'd just do what the current manual is stating and change out the filter that has picked up the jacket line contaminates.
Also, the new manuals for these things may not give alternative oils any more. More money to be made if all is kept "in the family".
Check out the cost to ship 2 five gallon containers or four 2.5 gal containers of Mahindra stuff to your place.
I'd even do it if it was a hundred bucks. You're gonna use $20 in gas. If you get a speeding ticket cause you're miffed at traveling all that distance, it's gonna cost more for you to go and get it. Then if you get in an accident with some jerk who is texting while driving, that's a whole nuther set of what causes "I shoulda" exclamations.
As an aside, I have a wood splitter that I bought in 1998. I use it maybe 12-14 hrs per year. I have never changed out the hydraulic fluid and it has no filter. I've just added to it.
In 1985 I purchased a couple JD tractors with one in my possession for 28 yrs. I changed out the hydraulic fluid twice. That tractor is still running.
We have simple tractors. Nothing as complex or touchy as a hydraulic run machine that every company sells. Keep that in mind when mulling over stuff like this.
Most of these hydraulic oils don't break down as they don't see the heat of say engine oils. What they do get infiltrated with is moisture. Rain, humidity, washings, etc. can get built up in a hydraulic line making the fluid less effective and with less anti oxidation properties.
The new thinner stuff may be more susceptible to this than the heavier old stuff.
Who knows. I'll change mine out at 500 hrs if it needs it or not.
Same attitude I have for the weekly bath.
