My 16 HP 1987 Wheel Horse garden tractor is beginning to show serious signs of age and I am quite confused about what to replace it with. I mow approx 2 acres each week, some flat with one small part hilly. I have no trouble going up or down the hill with my Wheel Horse, but I cannot mow across the hill, its a bit too steep. I also have several trees and flower gardens to mow around. Most of lawn was leveled many years ago with a bull dozer so it is a bit bumpy in parts. I will not be using attachments for the garden tractor in the future, but I do tow typical garden stuff around...stones, logs, brush ect. I have looked at the JD gx235 (18 HP), the club cadet GT 3204 (23 HP), and the Hustler Fastrac Z (HP 20). They are all within $1000 of each other. questions? which machine will give me the most attractive cut? which machine will likely last the longest? which machine will complete the job the quickest? which machine will give the most comfortable ride? which machine will be the easyiest to work on when the warrenty ends? Are there some questions I should have asked? Thank you for helping a confused homeowner.
