I would not have put the boss on such a trawl once and immediately a normal low trawl
With a good gangway he will send you, and so he will fall from the trawl and ask from the hard worker

You can't rock the car halfway. This is dangerous. The operator is acting unprofessionally.

Helping you do more work with maximum utilization rate, the durable design of the D9T simplifies repair and maintenance. Customers can rebuild these dozers with the same chassis over and over again with only minor repairs. With unmatched support from Cat dealers, it is not surprising that Cat large dozers have been up to 100,000 hours.
The D9T's main chassis have been developed to absorb the high impact loads and torsional forces encountered during very demanding dozer and ripper applications.
The main casing, equalizer bar cradle and front cross member are heavy-duty cast steel parts attached to the heavily loaded areas of the mainframe to improve stress distribution to increase durability.
Top and bottom rails consist of continuously rolled sections, giving the main frame superior durability.
The main casing lifts the final drives well above ground level, making them better protected against impact loads, abrasion and contaminants.
The pivot shaft and pin equalizer bar maintain alignment of the track roller body and allow the roller body to oscillate for a smoother ride.
