I have a Scag and a Kubota, among other grass cutting implements, dealing with a lot of grass across a property or two.
The Scag Cheetah is a hell of a machine. Mine has the fuel injected engine. It is my favorite of the bunch. The Kubota is a fine machine.
My lawn guy had a Gravely and a lot of experience on other machines. I asked him to use my Scag when he cut here to keep it run. When he bought another machine, he also bought a Scag based on his experience cutting our property with my mower. He said the speed and comfort was worth it.
I have zero ego tied up in my lawn equipment. They all came with the properties. My experience with repairs/maintenance has been that they are reasonable and typical for both the Scag and Kubota.
I have a cheetah with the 38.5hp kawi. Love that thing.
