I'm investigating the LS tractors as an option to maintain 16 acres I'm currently building a house on. In the course of comparing tractors I've noticed something odd in the specs.
I get that the primary difference in the R series and XR series is the emissions standards and different engines required to meet those standards.
When comparing shuttle to shuttle, the R4041 has an engine to PTO HP drop of 6HP whereas the XR4040 has a HP drop of 7.6HP. That's the difference between a 14.6% drop and a 19% drop respectively. As an engineer I can speculate as to transmission, PTO or quite simply test methodology differences but I'd like to know for sure.
I've noticed a similar differential with the R3039 and the XR3037 as well although reversed with the R series having higher losses.
Does anybody know what's going on with the specs?
