Kubota makes quality products. I own a L3540 HSTC tractor that I recently purchased used and a ZG222 lawn mower that we use to get up leaves and bag. I just traded a L3010 GST tractor in.
I ran a ZD326 mower for about 800 hours.
The issue is. Do you want a Kubota or do you want to cut grass?
We cut incredible amounts of grass. 90 plus yards every 2 weeks in the peak of the season and at times we have cut over 25 acres in a day.
In 2014 I demonstrated a Scag.
Today I have 3 Tiger Cat Scags with Kawasaki motors on them. The difference in the cut is absolutely amazing or has been for me anyway. There is absolutely no way I knowing what I know would pay the difference in the money to own another Kubota mower.
There is nothing that I have seen run that will touch a Scag mower. Many companies make mowers that are as good as Kubota when it comes to cutting grass and even reliability. Gravely, Bobcat, Hustler, and some others. None will cut stemmed grass with the Scags with the Velocity deck.
You can buy a Tiger Cat II with a 52" deck and a Kawasaki motor for $9K or less. Unless you run one like we do it will last you 20 years if you take care of it.
I have a Tiger Cat that was bought in July of 2015 that has something like 1700+ hours on it that abused is not a strong enough word to describe how hard it has been run. It runs daily.
If you want a Kubota by all means get one. If you want to cut grass get a Scag. If there were a better mower sold by a dealer in my area I would be running them.
