Probably all are but...the X55 series are more than "just" lawnmowers; the 955 I have is 30HP Cat-1 3-pt plus 5-ft bucket loader or bale spear, etc., so it's a very useful little utility tractor.
The 655 is on the way low end on the HP and I don't know what the capacity of the frontend loader might be as to whether it could pick up a 1100-lb round bale high enough to move it around a little like the 955 can, but it'll still be more than just a mower.
One big PITA for me that is a deal breaker is the operator station switch is interlocked with the PTO as well so (for example) can't use the handheld wand with the sprayer. One could add an override switch but bypassed in the entirety if fine as I think really is unnecessary.
I also use the frontend load a lot as a third hand when working by myself. In that mode I operate the hydraulics from the ground. There are just any number of things to do that do while not on the tractor itself.
I hadn't realized it had the tranny interlock even, the only way to have the hydrostatic "in gear" would be to be physically pushing the forward/reverse pedal while trying to crank.
