Dave,
I must respectfully disagree. It seems to me the proper approach to buying a tractor is to determine what implements one needs to do the work at hand, and then maximize the solution by buying the minimum tractor necessary to power those attachments. Tim
Hey, no prob Tim... Chicken -> Egg, or Egg -> Chicken, at least we're talking about tasty critters either way :laughing:
I see it as you buy the implements to match the tractor you have. We been hashing this out on the Cab vs No cab thread

I've got a 3520 Cab on a hair over 2 acres. And truthfully, if I woulda had the opportunity to get into a demo 4x20 Cab machine for relatively few bucks more like this deal, you can bet I would have a 4x20 Cab. I woulda pulled the trigger within the hour. Its not totally out of the question either, I'm designing my new garage build to have at least 1 9' door so I can get a 4x20 cab machine in there no prob. Absouletly no plans to upgrade because I have zero complaints with my 3520.
When my dad bought his
L2900, he thought "this is alot of tractor, I'll never need more"...and in time you soon learn to outgrow it. If he were to replace it tomorrow it would probably be with one from the top end (40+hp) of the Grand L series.
My advice is still "Buy the largest tractor you can comfortably afford".
Yet, the focus of many posts on this website is often on the tractor, not the implements needed.
This is true...I say thats because its relatively easy & cheap to buy/swap/sell attachments. Some people buy a landscape rake to put in a lawn and then sell it when the job is done 6 months later. Whereas buying a tractor is a long term deal. Not unusual to see items on Craislist saying "selling because its too big/small for my tractor".
With all due respcect, Using your sizing method, you'd buy all your attachments, and then buy a tractor to drive those attachments. If you found the tractor you bought was too small to run your 6' implements, would you sell your tractor and buy a bigger one or would you sell the 6' Rear blade and buy 5 footer?
