I had a 129 that my Dad bought new. I used it for years to mow and plow snow. I never put and thing but CC Hytran in it. I bought a new 3184 to mow my grass,but still used the 129 for the snow. The engine finally blew around 2012, so I bought an old 108 to plow snow. After a couple years, I finally got tired of the manual lift on the plow. Age had a lot to do with that. So, in 2017,I found a used 3225, with a plow . I picked it up and the gentleman, gave me a jug of Hydralic oil from Tractor Supply. I took the 3225 home and it didn't seem to have the forward speed, that my 3184 has. I changed the Tranmission filter and fluid, and put in Drive System Plus, and it runs a lot better. I only put what the manual says, in any of my vehicles. I didn't engineer it. If it costs a little more,it is worth it to me.
I buy it at Sam's club been using it for years no problems,Hytran is proprietary to CNH,does that mean that if GM say's to use only XYZ oil you cannot use anything even though the other brand it is recommended for GM,if it meets the specs whats the problem,in my diesels I like Delco 15/40 spec for those
engines & others.
Case/New Holland specs,MAT-3525,M2C,134D,FNHA-2D,201,00ms1207,ms1209.hope this helped
I use to haul oil in bulk, the manufacturers of new equipment require hy tran or any oil to be certified 100% pure. They give you a certificate to show it's tested for manufacturers spec's, in on site lab after it's loaded on my truck. That's part of the price difference, it's certified for warranty purposes. But I have picked up uncertified hy trans at same distributor and it came from the same tank as the 100% certified. IH, John Deere, Kubota... these companies don't produce there own oil or filters, it comes from oil and filter companies.
