First off, I have this working relationship withe old girl . It seems the more I use the Cub, the more I appreciate it over previous years of "modern" tractors with all their sheet metal stampings and complicated belt and pulley systems. Another is the 16 horse "thumper" has it's sweet spots if you know where to use them for the best RPM & avoiding least desirable ranges for hauling or mowing. The overhaul and Kirk's plate is paying dividends.
So the question is that now the temps are in the 40s with overnight lows in the 30s, when I start the tractor in an afternoon, the hydro unit tends to "howl" a bit. Even with a 2 minute warm up, moving forward is a bit jerky. After about a half hour and things have warmed up it's more normal. It has new Hy-Tran with probably no more than 60-80 hours on it and filter from Case-IH which I believe is the usual 15-20 micron rating. Are these hydro Cubs cold blooded as they say until they've "had their coffee"?
