I paid $500 3 years ago for a 4' cutter, Fred Crain Agri-Cutter 104. It's built like a tank and uses the same gearbox and I believe blades as Bush Hog brand cutters.
Now, I'm not sure if they are available in Jersey but I'm sure you could have one shipped there for under $1400.
What will you be cutting with it; a weedy meadow or 3" diameter saplings? Are there rocks, stumps or other junk is the area, or is it clear of damaging obstacles? How many hours/acres per year do you plan on cutting with it?
I've looked at the light duty King Kutter at Tractor supply and they look like they'll last years cutting a weedy meadow. But I don't think they would last a season used on 7 year old clear cut regrowth. Not everyone needs the most rugged cutter available, but if they do anything less will be turned into scrap metal pretty quickly.
I'm in my 4th year of using a 5' KK I bought for 200 bucks used. I'm planning to upgrade to a higher quality 6' cutter, but the KK just keeps hanging in there even through work that's really too rough for it. The KK is a low buck unit and won't have the quality or durability of the more expensive major brands, but it will do a reasonable job and is a lot lighter on the wallet.
In my opinion the King Kutter would be all you need.
Cleared my property with a 6' KK w/slipclutch. Hit many dirt piles, found several bricks with the cutter, a couple cement blocks, Etc. Worked fine , no damage.
I just purchased the Rhino TW60 yesterday. It is definitely heavy duty. It seems steel surcharges are still pushing these things upward. I got the following prices in Georgia. The Rhino lighter duty model SE5 was $1195 which seems heavier than the Bush hog model which I received a price of $895. The heavy duty models are almost 300 lbs heavier but generally $400 more expensive. I like the idea of cutting down small trees /forums/images/graemlins/smile.gif.
