Okay, awhile back I lambasted my newre John Deere JS-63 mower for not mowing as well as my very old one with Briggs and Startton engine that finally gave up the gost. Well, It does not do as great of a job really, however It really did a sweel job the other day . It mowed 1.1 acres of very tall moist grass(we had a very wet summer here in S. Cntrl. Tx) and my grass never compaletely dried out. My lot is very wild.Im satisfied with the perforamnce of the Deere. It idles so low tho. I wish it would rev the heck up like my old Deere, but it cut some pretty nasty stuff, moist, and a lot of it, sio Im going to say its a good mower aftewr all. Thanks
