Good work, guys. You solved a problem that plagues many small tractor owners;weight. Sorry to say, but most of these small tractors are not very useful, even with weights, A gas powered large garden tractor will out preform many of them. I know my 14hp Bolens 1476 Large frame is heads and tails above the 15hp Bolens Iseki 4x4 diesel I used to own. It was a complete joke. My friend has a new John Deere sub-compact and a older Kubota sub-compact and I don't think much of them either. They have to be light enough with the hp offered, and the hp offered wasn't enough for the weight of the tractor alone, that kills its usefulness.
