| I think that all equipment manufacturers let the hydraulic oil get to warm on these tractors before trying to be more aggressive cooling it down with fan speed and their thermostats in the oil cooler lines. 170 is probably about as hot as that oil needs to get I’ve noticed we blow more orings in our planter hydraulic valve stacks when the oil is hotter than when they run cooler. If my oil stays in the 160 range I never have oring problems | |
