A friend of mine has a Kubota ZD28 hp diesel. Complains of leaving ruts in yards that are slightly wet. I don't have that problem with my Hustler Z. I looked up the weight of the Kubota, 1600 lbs compared to the Hustler Z at 1100. Its long frame at 89" compared to 75" on the Hustler only helps to place more weight on the rear axle where the engine is. This mower is too heavy for most residential lawns. Diesels are great, but this mowers niche is not in the residential market. Any opinions?
