I'm a first time tractor buyer so take some of this with a grain of salt. But I did do research before buying and killed several MTD pieces of crap before getting mine.
I am looking to buy a TLB. I will also need a post hole digger, reverse tiller, pto generator, and, eventually, a finish mower of some sort.
You requirements:
-- post hole digger: Assuming you aren't putting fences in all the time these can be rented for about $30-$50 a day. If you are industrious you can probably get them all dug in a day or two, even if you put the posts in slightly later.
-- reverse tiller: Again a rentable item. But the uses depends on size and intent. If you need to plant the garden in the spring do you really need to own one year round.
A lot of 3PH attachments can be found second-hand cheap, rented or bought outright for under $1K. You need to figure the trade offs in use.
-- pto generator: I was looking at this over the winter. I found that the cost to buy a high KW pto generator was almost the same cost as buying a smaller gas generator that allowed me to still use my tractor for things like plowing out the driveway.
-- a finish mower of some sort: It sounds like you'll need a bush hog for the initial pass. Another rental item. My dealer loaned me a bush hog for a weekend for free to get the grass/brush down. Now my MMM does the job fairly well.
So buying a CUT/SCUT with just a MMM or rear finish mower -- go get a ZTR. The utility is easily added to by at least getting the FEL. I would suggest considering a backhoe as an option as well. That is an expensive add on that can be financed in the original purchase. Where getting it later can be harder to do.
Looking at the map, Buckingham, Pa appears to be relatively close to Allentown (50 miles). There is a Mahindra dealer there. They should have a 0% for 60/72 financing deal as well. I went with a Max25 FEL/MMM/BH. I'm mowing 4 rough acres, it's done well in the snow, dug a nice burn pit and pulls out the rail road tie fence posts the prior owner left. It's even pulled my car to the end of the driveway in the snow a few times.
So before you spend money and get locked in -- take a look at all the options, and requirements and decide. You can probably hit the local dealers for their attachment rental prices.
