Looking at replacing a 5 year old Scotts 16HP 42" lawn tractor with a ZTR. I have apx. 1.5 acers all basically flat. I started out looking at the toro timecutter, cub cadet and simplicity Javelin. In the past week I've been to about every dealer in town and looked at Gravely, Exmark, Husky, Simplicity, Toro, etc and I think I have narrowed the choice to the following two. TORO Z400, 18hp Kohler, 48", $4,999 Simplicity Champion, 20hp Kohler, 44", $4,850 Which one do you think would be the best bet? Should I include the Fastrak in this list? The only problem is that I think it has the EZT drives. Thanks for any help!!
