Norscot Caterpillar D8R II
This is Cat's most well known dozer and it is big as seen with the man stanging on it.
Here is the rear of the machine with work lights and a 3 shank ripper.
The front shows the lift cylinders and work lights.
To make this model better I cut off the casting knobs that limit blade movement. With this change the blade can move up and down just like the real machine.
Here it is with the blade raised high and the ripper lowered all the way down. The ripper goes way down.
Here it is next to the D5G.
