Between Exmark and Kubota I would choose Exmark every time. Kubota s are well built but Exmark is a way better engineered mower for the commercial LCO. We have ran JD, Exmark, Toro, and Scag for Zero turns over the last 20 years since I have been in this business. We bag a lot of grass and so far overall Exmark has been the easiest for our mowing crews that don’t know if they will need to bag from job to job.
Scags are excellent at everything except bagging as it takes 20-30 minutes to put on or take off the bagging system. If we didn’t bag when grass was long, wet, or leaves are falling Scag then Deere would be my first two choices. Overall they cut best in all conditions when not bagging but Scags definitely have a more comfortable ride.
As far as hills go we deal with the worst of the worst as far as hills go and Exmark, Deere, then Scag is how I rate hillside performance. Depends on what you do with your company. I purchased all Scags trying to cut back on bagging so much and it definitely worked. If it needs bagging we do it. Only problem is that the customer our crew spends 2 days a week mowing wants everything bagged weekly so they don’t track grass in the houses we maintain for him. Either going Exmark or JD for Zero turns next time around depending on the ease of switching from side discharge to bagging on the fly.
