icat,
It sounds like you've got a real good price, especially with R4's. Deen's deal is with R1's. Deen told me that the 3130 would handle a 6' rotary cutter just fine. Rule of thumb is same size box blade and rotary cutter, and don't forget that your tractor's footprint is 6' wide.
Also, that SS/QA option is supposed to be real handy. It's probably an extra $300 or so, but gives you flexibility to use pallet forks and a bale spear. /forums/images/graemlins/cool.gif
Like I said in another thread, this package is the one I want, if I could only justify it. Right now, I only get to see my tractor about once a month, but he's old and doesn't mind. /forums/images/graemlins/wink.gif
