how are you going to handle tree stumps / root balls... that is the big question there. from 3pt hitch backhoe, mini ex (mini excavator), to tree stump grinder, (just removes what is above ground and maybe a little below), to a dozer.
your big ticket items tend to be... FEL (front end loader with general duty bucket), tractor itself, and then a 3pt hitch backhoe with a sub frame for it. getting the big ticket items all at once on same order from same dealer. the dealer may give you a bigger discount.
some folks save up projects and rent a bigger machine from time to time. for example a larger excavator vs a mini ex. to do various jobs in one wild weekend non stop running the machine. while others justify cost of having one around when ever they need it.
=========
rotatory cutter (bush hog = name brand), are all over the place from third party manufactures. rear blades, box blades, graples, etc...
exception with above, if you want a grapel, and not enough cash up front for it, go ahead and get the 3rd function valve kit, for the FEL (front end loader), more likely save you some costs long term having dealer install it before it is delivered to you.
i would suggest AG / R1 tires. due to more likely you will be hitting a lot of mud/dirt/etc.... and industrial / R4's = you being stuck in the mud, (regardless of 4x4 / MFWD, differential lock, split left and right rear brakes)
if you are looking at possibly a electrical winch for tractor, see about getting the larger alternator if option for the tractor.
a lot of folks like TNT (top and tilt) a hyd cylinder replaces top link on 3pt hitch, and for tilt, a hyd cylinder replaces one or both of the side links / turn buckles on the 3pt hitch. if ya going for TNT, would suggest bare min of 2 to 3 rear remotes. again might be cheaper long term to have dealer installed, before it is delivered to you.
===========
all the little options due tend to add up rather quickly, making a larger tractor out of budget vs a smaller tractor with all the extra smaller options. many of the smaller options can make many tasks quicker / easier / more professional done with out much extra fuss. smaller tractors just take longer at certain jobs. the only issue is skidding logs, the bigger and longer they are, and more hills ya gotta climb, a bigger tractor will more likely keep on going vs a smaller tractor. but you could always chop log in 2 or more chunks. to drag up and out of the woods.
