I understand I'm asking this question in a Hustler forum, so go ahead and give me your sales pitch...lol! I'm trying to compare the Mini Z to Gravely's PM152Z. I haven't demo'd either product yet, but do understand the importance of demoing prior to spending my hard earned money. My question is how do these two machines compare? On paper, they look similar...same engine, similar decks, both appear to be built like tanks. This machine will be used to cut my residential 1.8 acres. The land is a little rough in spots. I'm guessing I will have to pay for the suspension seat on either model I choose. I'm looking at these (and other similar machines) because I want quality and durability. I don't plan on having to buy another mower for a LONG time....like 20-30 years...is that a realistic goal? Also, as far as replacement costs, can you tell me what it would cost if I had a spindle go bad to replace the parts? I'm trying to find out that piece of information also for different manufacturers to make sure I don't end up buying the one machine out there that the parts are 20 times the cost of every other machine! Thanks for the help!
