I have been throwing this around for the past couple of days and I really need some advice. Here is the situation. I have a Cub Cadet 1548 commercial mower. This year I have increased the number of lawns from 5 to 16. I have been working really hard to get into an upscale area where I live and have 2 lawns there already. They are about 3/4 of an acre. The rest of my clients also live in very nice neighborhoods and have anywhere between 1/2 to 1 acre lots. I will be placing door hangers and working the rest of this neighborhood this weekend. The two clients are really happy with their lawns and they have agreed to let me use them as referals. Well I teach full time and am working really hard to make this a full time venture. I have two torn miniscus's on both knee's, dt a slip and fall on the school property this year, which will require surgery. I am trying to put off the surgery. I have tried a sulky but I also have gout of the big toe. I do not want to give up my clients and the mowing right now is not only taking a large part of the week, but the pain in my knees is causing quite a bit of havoc. I am thinking about going to a ztr...and am looking at the Cub M48 with a 19 horse Saki. The dealer is willing to take my mower on trade and give me $2500 for it. Mtd is currently running a promo for 3 years with 0% which also requires some initial down payment of around $400 to get into the program, which the dealer is agreeing to eat the cost. Should I get the 48...I would like the 54 but just cannot afford it. Your advice will be carefully listened to.
