i have a 1520, it is 23 hp with 18 pto hp, bought it about 1993, like it a lot, i have a 5 ft king cutter that i use to trim the pasture, if you get in to very deep grass and weeds, you need to slow down, just go slower and you will get through just fine, the hydro drive is very handy at adjusting speed easily. love that tractor.
