I am lookig at buying my first ZTR. I currenty cut 1.75 acres of centipede with a Home Depot Scotts(made by John Deere) 17hp kohler 42" cut. I have been using this mower for 4 years and it has been flawless. The only problem is that it takes me close to 3hours being I stripe or attempt to stripe the lawn. With that said I am looking at either a 18hp 44" FasTrak or the 20hp 52" FasTrak. The 20/52 is only $200.00 more. Is the extra 2hp enough to support the extra 8" of cut? Is it wort the extra 200.00 and the extra blade cost just to say I have a big mower. I do know that the 18hp/44" will walk circles around my current mower so should I just save the extra cost and settle for it? Also has anyone had any experience with the hustler bagger system? Does it work good? Are the blowers a problem? THANKS in advance for you input.
