What do you suggest I do? I'd like to try thinner oil to see if the controls smooth out. I'm worried about screwing up the hydros, though. I wonder what the other mowers that have these hydros use for oil.
Use the J20C?
OK. My worry is wearing the hydro out with inferior oil. I'd like to try the low visc to see how it feels. Mower is a different machine after its warmed up... does oil flow easier when warm? Is the final viscosity the same?
Hi there.
I have a JD Z820A Zero Turn mower with 430h. This design was plagued with more than a few user experience and control issues. Basically, the ZT, specifically the hydros, left a lot to be desired out of the box resulting in an update campaign and even some dealer buybacks.
I've read...
Thank you for the input, everyone.
It seems -this time- I will bite the bullet and travel a good ways to get the oil specifically named in my manual. I will snip the filter boxes to keep the labels, my receipt for the supplies, log my service date and hours, and keep them in my maintenance...
Kubota replied to me but it wasn't particularly helpful. They gave me the SDS for the oil-not the certifications I was hoping to get.
Looks like I will be traveling a few hours to get the Permatran 821xl...

Hi Zeng,
So the SUDT2 would in turn be less viscous at or above operating temp than Permatran 821xl, right? Many people across...
Here is a picture of the previously referenced document that doitmyself shared. Dated 2010.
I have emailed Kubota Customer Service to ask for a new list of certifications and shared the document for reference. Maybe I'm thinking about this too much.
I will share their response. Maybe it...

I definitely agree with that. I wonder if because of this, oil shear is happening causing...

I reached out to Messick's Equipment, a Kubota dealership with a lot of presence on YouTube. I asked their thoughts on using Super UDT2 in my GC and they told me it would be fine.
I know they're not on the hook should something happen. I wouldn't expect anything to, but who knows? Maybe my MF...
I live in Northern Ohio. Even though this past year we've had rather mild winter, we have had a few days of below 0F. Naturally, the day I needed to move the snow off my property was one of these days.
I did not notice anything exciting about the cold weather operation. Maybe a little bit of...
I understand.
I assumed that a lower viscosity oil could potentially run smoother, provide less cavitation (seemingly evident by the groaning noise that has increased in noticeability over the last 50h since the day I've owned my tractor), and maybe generate less heat.
I am unable to find...
Hi everyone,
I have a 2018 Massey Ferguson GC1720 subcompact tractor ready for the 50 hour maintenance.
I would like to run a full synthetic for my machine wherever I can. I am going to put full synthetic Rotella T6 15w-40 in the engine, and use a Mobil 1 filter, there.
The manual calls for...
Thank you!
The tick is there when warm. I noticed it most after driving it a while warm. I'm trying to stalk other trucks with the 5.3 to hear if theirs sounds similar. I read that these can be rather noisy engines. When the weather is above...say, 40 degrees F, I hear almost nothing.
Seems...
