Long time engine maker Kubota has expanded their product line into GSE. Their Spark Ignited line of engines offer fuel-efficiency in gas, propane, natural gas or dual fuel configurations. Two members of the series, the WG3800 (3.8L) and WG2503 (2.5L), have outputs of 61.7 and 97.9 horsepower and are mirrored after Kubota’s diesel line. These industrial-based gaseous engines have similar power and torque, lower acquisition costs and can be used wherever Kubota diesel equivalents are currently.
