  1. I have a Kubota ZD1211. motor and controls are pretty good. We use our mowers to cut for a local power co. Grass heights range 7 to 16 inches at times. The pro deck pulleys are poorly made . I have had to replace 6 pulleys over a year and a half. Same thing with back rims 26x12x16 . Replaced 3 already They put 4 ply tires on. High priced mower .Around 15000 out the door. They have tried to cut costs and affected some major components for durability. Parts are also pretty expensive 58 to 85 dollars for pulleys . And tires and rims are specific to that model. Quality of cut I would rate at a 6 at best. I would suggest demoing the mower before you buy .Good Luck . I have owned 8 of these mowers since they came out with the ZD21 model. I am looking for new mowers now. I think another brand .Hope this helps the people with deep pockets in business.
