Rotary Cutter Single or dual spindle rotary cutter

A 35 hp tractor and a 84" Woods might not be a prudent combination, even with the "standard duty" unit (which is a lot lighter than their medium duty one). I've a single spindle "medium duty" Woods BB600 - in heavy stuff (brush, very thick weed patches) the tractor is burdened (a 34 hp Kubota - 28.5 pto hp), and the tractor is light in the front if I take the FEL off (& mowing with a FEL is a hassle if you've a bunch of trees or other obstacles to dodge). So, you must be referring to their "standard duty" unit - even then, the Woods web site would indicate the 72" standard duty is a better match for a 35hp tractor (3pt lifting capacity, fore/aft tractor weight distribution & pto capacity) - and that's what I getting when my property gets smoothed out enough that I don't need a brush cutter that annihilates anything in sight. My BB600 sucked a half buried 5" X 4' log out of the ground this weekend, and turned most of it into sawdust before I could disengage the pto - 4-5 seconds - that's impressive, but a 72" unit would sure get my grassy sections mowed quicker.
Dual spindle have real advantages, which have been listed in the posts above - but they are "light to standard" duty. Unless you're getting a forestry grade cutter, don't plan to use them on anything more than grass/weeds and minor brush.

Derek,

I have borrowed my father-inlaws 3710 and 84" dual spindle Bushhog brand rotary cutter and found that the tractor handled it quite well. I was able to maintain a decent ground speed in heavy grass taller than the hood. Also handled light brush well. Did'nt have any heavy brush to cut. From the description of your intended use and the size of your tractor, I'd say 84" would be fine. Just remember, wider deck and rougher ground=more scalping.

Yep, my TC35 handles it with no problem. Just finished mowing about 5 acres of Johnson grass about 4-5 ft. high with no problems. When I agreed to buy mine I didn't realize it was such a good price until a week or two later. I was more interested in getting that extra foot of coverage over buying a new 6 ft. single spindle for around the same price. I think you would be happy with it for your purposes.
