Looking for a mower for my business

I want to get a new zero turn for my landscaping company but can’t decide on what mower. I’ve worked on plenty of small engines over the years and I’ve always preferred Kawasaki and Briggs motors. I’m looking at the Toro Timecutter Max and the Ariens Ikon 60-in. I want something in that price range that I can’t trust to run 8-10 hours a day with as little issues as possible. This machine will be ran in various yards/terrains throughout the day. I’m open to any suggestions. Please keep in mind I have had very bad experiences with kohler motors in the past.
