Man some Cat sales guys can spin lines! If you buy the PT100 ask for the brush kit, it blocks the air intakes near the loader towers from sucking inthe brush. The Pt100 has signifigant changes to theRC100 undercarriage. It also has a new guage cluster and a metal hood. That machine boasts 100 engine HP via a 4.4L engine 144lpm flow 3300 relief valve pressure and 74 Hydraulic horspower. The only thing near it for hyd horspower is the TL150 but it is rigid frame and heavy. On theSR70 there are service bullitins out to address all the issues with it that were posted. this will be a good machine once the bugs are ironed out of the new machine, the UC is bulletproof almost.
