Rotary Cutter Rotary Cutters

[LD1]

His tractor shouldn't have much issue lifting and driving around with a 7' cutter. Your simple lever formula for 3ph lift capacity is just plain wrong.

I think a few mfgs make some twin spindle lighter units that are 84" wide and are offset. Of mowing fence edges is a concern, those are an option.

The OP may need a heavy duty rotary cutter, or he may not. He and his budget will decide in the end.

I cut heavy brush with a 15hp tractor and a 4' Kingkutter to make trails. After that, it was a matter of cutting light brush and tall grass to maintain trails. If you're always cutting heavy brush, you are not maintaining/cutting frequently enough.

Again, I had zero issues with the Kingkutter. Obviously, I took t slow when cutting a trail for the first time. It just takes a little common sense - you just have to listen to your mower. Some people just do everything wide open and break equipment.

If the OP has the $$ to buy better, I think that's great. If not, buy what you can afford, be responsible when you operate, and get a lot done.

There are also aluminum cutters available that are much lighter.

I think someone will eventually use some engineering and make a better bush hog instead of just throwing steel at the problem.

There's always a better way.

Example(s)?

Maybe I have spoken too soon. But if I made them I'll bet they'd sell like crazy!

I doubt aluminum would hold up well to the abuses. Crap flying at high speeds under the deck would ding, gouge, and abrade the aluminum alot faster than steel

For a number, a 2500# lift spec (when new) say at the lift arms, figured out 10' is only 250# of lift capability and at that the engine has to be at PTO rpms to get it.

Got anything that backs that statement up?

This is a heavy duty cutter to me just to be clear. If it has less than a 7ga deck it's light duty IMO.

Done some more looking an I think there is no way the 110 is 86" wide. My 18k lbs Ford 5500 is only 81" and dad's 12k lb 4500 is 75". And the fact that the 110 only has a 6' FEL bucket.

I am guessing the 86" is the width of the outriggers when fully down? And am betting a 6' would cover your tracks....although just barley.

But given the weight of the machine, if you can find a good price on a 7' cutter either single or twin spindle, I would not be afraid to get one.

I am actually semi-looking for a 7' twin spindle for my much lighter 29hp rig. And if they made a lighter duty 8' twin, something In the 1000-1100# range and not 1800+ like I see, I would be looking for one of them instead. And if I get some things knkcked off the to-do list and still haven't sourced a 7' twin by then, I have aspirations of building a 8' twin that is lighter than current offerings.

For a reference, here is a light duty 5' KK (~500lbs) next to a 6' bushhog 306 (~1100lbs). And that wasnt even the heaviest offering from bushhog in that line. they made a 406 @ ~1500lbs. Had a beefier gearbox, 1/4" deck instead of 3/16", and 5/8 x 5 blades instead of 1/2 x 4
