Kubota ZD321 is one of the toughest mowers on the market. Its made for large cutting jobs. You can cut 20 acres on both tanks, and never stop. It will only get better as it only has 250hrs on it. The engine still is not broke in fully. Its got weight adjustable seat that makes the ride real nice

　　the deck is hydraulic with foot controls. It is I believe a 2009 model . I bought it in the fall of 08. The deck is a 54" ,it works better in smaller areas . The only difference really in a 321 and 326 is 5 hp.The last 2 numbers in the model is hp rating . This machine has been kept in a shop its whole life, and other than my wife no one else has run it. When invest as much as i did in these mowers you don't let just anyone on them.

　　The hp rating is 21. I used it a few times on a large site along with my zd21. Between the two mowers 25 acres in 6hrs, I bought the mower new, the hour meter is correct. At this time it reads 247.hrs The majority of the time that I have owned it It cut my yard.I purchased it for a spare in case my zd21 broke down. It still has not broke yet. The meter has never been disconnected . This machine is like new, all safety switches work. It just needs to be used, its never given any trouble at all. Other than the occasional tire needing air. I know it will be the last machine a home owner would ever buy , They can expect at least to get 8000 to 9000.hrs from the diesel engine. Compared to 2 to 3 thousand from gas engine. If it is to be used for commercial this is a great choice
