Buying a FEL won't be overkill, let alone a 2305.
I only have 2 acres to cut and bought a 4115 with FEL, tiller, MMM.
Used the FEL to do snow removal from a 70' (+ or -) driveway;
by the mailbox so the postman (or lady) has a clean entry/exit way
to the mailbox; and the entrance to the sub - it's usually a few hours before
the sub's contractor shows up to do snow removal.
Used the tiller to reclaim some land outback.
Am now trading up to a 3520 with FEL/MMM/655 tiller - now this
is overkill, BUT nothing beats a couple hours of seat time on a tractor -
well, one time comes to mind but I'll refrain from comment.
When I bought the 4115, I thought massive overkill! Looked at
the 430 and like diesel-powered lawn/garden tractors, but the price
differential between them and the 4115 was only $1-2K. Didn't
take a rocket scientist to look and see which one could do the most
work and last the longest - NO OFFENSE to 430 owners, etc.
Though, the ONE drawback to having a 2305 on one acre is
what I felt when I took the 4115 out onto 2 acres - you feel kinda
ridiculous sitting atop this "big" tractor on such a small lot, relatively
speaking. BUT you'll get over this quickly after 5-10 minutes of
puttering about.
This is one great forum (tractorbynet.com) - great info, great people!
Good Luck and Enjoy!
