Does the 757 with 60 " deck have enough power for thick spring growth? I understand that the 777 or 797 do not have any trim ability with a 60" deck. Looks like a great little mower but I would rather have at least 27 hp with the 60" deck. I'm talking bi-weeklys and thick spring growth. I mow some thick grass and not sure the 25 would handle it at any reasonable speed. Not buying this year just learning.
