Prototype Cat Tractor and Road Groomer

[RM model Mack]

Awesome idea! I do have a tank/pump setup from an abandoned tracked brush fire vehicle project and will try to retrofit them.

On a side note...

The XL 2.2 tires have created some issues in the form of...
1. inner tire rub on the leaf springs at full steering lock (even at 55% EPA)
2. too tall gearing. The disruptor trans has the smallest pinion in it, so no further reduction options available

so here it is on 1.9 mud bashers. These slow the tractor down a lot and eliminate rubbing even at 120% EPA. Looks more scale now too I think but I'm open to opinions (1.9 vs 2.2)
