Does anyone have any experience with a MMM with the Grand L series? In all the Kubota brochures it shows a GL3940HST with the mmm. I personally like the mmm vs. the rear finish mower for mowing my lawn. I like ALL the features of the GL series but would like some insight as to the practicality of a machine of this weight for mowing? I am in the market for an upgrade and would like the largest Kubota available with the mid pto. Many thanks
