I am considering a new mower. Looking at Scag Tiger Cat or Gravely pro turn 148. They both look like good mowers, but the Gravely is less expensive. The Gravely has the option of the EFI Kohler engine and the Kawasaki twin. The Scag just comes with the Kawasaki engine. I'd appreciate any advise or comments about these mowers. Any comparisons would be helpful and appreciated. Thanks in advance for your help.
