Like the one in the link below from a Ritchie sale. Variable Pressure, or Variable power, or am I wrong on both thoughts? Thanks in advance, sorry if this is a stupid question. https://www.rbauction.com/2012-caterpillar-d6t-lgpvp-crawler-tractor?invId=3902821&id=ar
LGP stands for low ground pressure and the VP should be VPAT meaning 6 way blade.
Variable Pitch
