Should be near bulletproof, and the mechanical/hydraulic features are common to all the tractors of that era - just somewhat better built than most. There aren't many simpler tractors ever built. The JD1050 is actually an older model Yanmar tractor to which some updates were added. So it doesn't do any harm to confirm this.Īny independent mechanic who won't touch a JD1050 is not someone I'd want to use for anything, even oil changes. IN the case of the oil question, I asked the service manager, he called technical at JD on the spot, and then turned to me and said that the difference between the regular and low viscosity Hy-Gard was in the proportions of the additives used, so they could be mixed for intermediate values.įor all I know, he might have been talking to Santa Claus - and you don't know me either. Locally it is common for the service techs, parts guys, and the service manager at the yellow JD dealers to be dedicated professionals versus the help at the green JD dealer which are not that well qualified. It has a Woods loader and I run a grapple, 3ph round bale spear and Woods grader.Ĭlick to expand.The oil question should be independent of what model the Hy-Gard is being used in. Should I run the Low Viscosity Hy-Gard or switch out to regular Hy-Gard? Overall, it's not much of a problem just different from before. I'm thinking that the lower viscosity is letting the gears spin freer hence the extra time to wait for them to stop spinning before I can shift. I do need to check the adjustment of the clutch petal but I think it's also okay. By the way, I'll beposting the measurements of that special tool in case someone wants to re-create it for their own use. I know the clutch is adjusted properly because I checked when she was apart with a feeler gauge and special tool JDG-52 (yes, I bought it for $99!!! ). My experience is similar to this post: John Deere 950 light grinding into gear
Never had that problem when I ran straight Hy-Gard. The fluid meets transmission and hydraulic fluid requirements. The viscosity of this fluid is equivalent to around SAE 10W-30. MOBIL Fluid 424: Mobil Fluid 424 is a mineral oil-based fluid. Before choosing the substitute oil, keep in mind that John Deere uses oils of viscosity 10W-30. However, I have since found the temperature graph below and it's got me worried that I should have gone with regular Hy-Gard due to the max air operating temperature of Low Viscosity being only 86F - which in Virginia it gets much hotter.Īfter putting everything back together, the tractor runs & operates as normal but I now have a slight grinding when putting her into gear if I don't wait an extra second or two for the gears to stop spinning. Substitutes for John Deere Hydraulic Oil. I did do a cursory look online and found a JD document that stated both were acceptable in these tractors. When I went to the John Deere dealership to buy new hydraulic fluid, I was about to pick up regular Hy-Gard but the man behind the counter said, "Wait! You need to use Low Viscosity in the 950 & 1050s!" So that's what I bought - 6 gallons cost $165! I recently had to split my John Deere 1050 into three pieces to replace two seals in the clutch input shafts.
