I'm purchasing a used zero turn for my 4 acres of yard. For $4,500 I can purchase a 2018 Cub Cadet Pro Z 160 (lap bar) with 240 hours and a Kawasaki FX engine, or an Exmark Lazer Z E-Series with 1,000 hours and a Kohler engine. I like the idea of something newer with less hours, but always hear great things about Exmark. Both are rated for similar speed, both have 12cc hydro pumps, but the Cub Cadet has Hydro Gear ZT3400's and the Exmark has Parker axial piston pumps. Any opinions?
