Been there done that a few times. Boss filled em heavily on the 235D and it took 2 of us a day and a half with jackhammers, hilti drills and flamo's to get them cleaned. Lesson Learned.
Shovel them daily no matter what, have whoever fills them help clean them or pay the Overtime to clean them, and think when traveling through mud to avoid if possible turning and filling them heavily. Some guys (not directing to anyone imparticular) dont think about it when they churn and turn in the smag, then work till quitting time and bail as soon as the clock hits 5.
I raise he11 when people leave my tracks full. I quit half hour early or stay late to clean then. Most bosses do not want to lose that production or pay the overtime, but its part of working in winter. Some understand it, some dont, till it's down in the shop and their really PAYING... But of course, then its the operators fault..
