A powertrain for a machine includes an internal combustion engine, an aftertreatment system including a selective catalytic reduction (SCR) catalyst for treating exhaust gases from the internal combustion engine, and a continuously variable transmission operatively coupled to the internal combustion engine. An electronic controller can measure a catalyst temperature of the SCR catalyst and can inversely adjust an engine speed and a CVT output to selectively regulate a catalyst temperature of the SCR catalyst. In an embodiment, the CVT may be a hydro-mechanical transmission including a hydrostatic transmission and a mechanical transmission.
