Hi everyone,
I have a JD 4115 and the manual's fluid recommendation for the transmission/hydraulic fluid contradicts itself.
This is for lower Michigan where we see wide temperature variations. The tractor runs 80% in the "summer" with temps often over 80F. I snow plow with it about 5 to 8 times in the winter and the temps only occasionally go below 0F.
The fluid chart shows Low temp Hy Gard good from -40f to ONLY 80F. Regular Hy Gard is 0F to 122F.
The manual states: Use oil viscosity based on expected air temperature......... JOHN DEERE LOW VISCOSITY HY GARD IS RECOMMENDED (my emphasis). Standard Hy Gard may also be used. The Low vis is recommended several other times in the manual (top offs, etc.).
One dealer told me Low Vis is factory installed and stay with that regardless of the temp chart 80F max. "These smaller tractors need less viscous fluid".
Another dealer said stick with the chart and use standard Hy Gard year round because it fits our temperatures better.
Has anyone figured this out or received a definitive answer from the company??? It shouldn't be this hard! And, I don't want to mess up a $12,000+ tractor.
Thank you much!
