I am coming up on my 50 hour service for my 1025R and have found some interesting information on the trans/hydro oil. This information may have been discussed before but I could not find it on a search. I apologized if this has already been discussed.
As per the service manual and my dealer all 1025R come from the factory with low vis hy-guard no matter where the tractor is shipped in the country. On the dip stick is says to use low vis hy-guard. However, On the back of the low vis hy-guard bottle is says to use in ambient temps from -44 to 86 degrees F. On the bottle of Hy-guard is says to use in ambient temps of some around -15 to 122 degrees F. I have questioned several people at my dealer on this as my 1025R is used in 90 degrees plus quite often. Me dealer tells me that Deere says to use the low-vis in the 1025R and other Scut and mowers not matter what the ambient temp is because it hydrostat trans needs the low vis. The standard hy-guard is not designed to be used in those hydrostats. Has anyone heard of this? Is anyone using the standard hy-guard?
I have owned a 445 for 16 years and been using the low-vis in it's hydrostat and never had a problem with it. And I have mowed many many times in 100 degrees plus for 6 and 8 hours at a time. So maybe there is no problem here. Just a little second guessing myself with the product label contradicting what the manufacture is recommending. Thanks.
