The three most popular Honda trimmers are the HHT25SLTA, the HHT35SLTA and the HHT35SUKAT. The HHT25SLTA uses the smaller 25cc GX25 engine while the HHT35SLTA and HHT35SUKAT are both powered by the 35cc GX35 motor. The difference between the SLTA and SUKAT models is the SLTA is a standard loop handle, but the SUKAT has a commercial bike handle and uses the "Kwik-Loader" cutting head or 50-tooth Honda brush cutter blades.
