How many hours on your tier 4 tractor

[dadster4]

First regen at 17 hours, next at 57, have about 70 hours now...no issues with tier 4
Seems new technology scares some out there, fuel injection used to be a new thing, as was electric starters, even rubber tires!
Who knows what the future holds?

Another regen at 73.3 hrs. A lot of backhoe work in cool weather, trenched 180' x 2' deep, and pulled a couple old stumps. Regened while using the hoe...decreased power for 5 minutes but didn't affect my fun!
