Greetings, Appreciate the info here that helped me choose Ferris IS for the estate I maintain. My employer gave me free rein to pick brand and model size for mowing his estate. He and I both appreciate fine equipment, and want to size it for a long life. Will be used as follows: five acres weekly of finished lawn; some areas a bit rough; twice yearly mowing of 1.5 rough acres between trees (mowed high just for weed control); ocassional light bagging if clippings not dry before parties, etc (aftermarket, non vac likely); pulling small eq trailer with weedy and push mower; ocassional mowing paths through tall weeds (not brush!). Lots of trees to mow around, but lots of room between them. About 50% straight unobstruted mowing. I figure deck of 52-61" has lots of working room. I'm looking at machines from 1500, 2000, 3000 series. Based on usage, and keeping it large enough (frame, motor, spindles) to go 10 years, what are your suggestions? Money is not the objective, but I don't want more machine than I need. Thanks in advance.
