Mowing Brush cutter size

[reddragon774]

I have a LS 4145 and am wanting a brush cutter....do ya think it will handle a 8' ft

I would say no on the 8ft. With the hydro you have 36 hp. at the pto. I think a 6ft. is about the right size. You have to look at the cutters required PTO hp. and match it to your tractor.

I think the price of a 8 foot would give you a pause too.

Six foot and Seven foot diameter should be OK. Eight foot width is too much for your power.

Consider how far behind the tractor an eight foot Rotary Cutter trails~~~~~~

Woods has an 8' multiple spindle pull-type cutter that has a recommended minimum 35HP:Product Details.

I run a Rhino 172 which is a 6 footer on my Kioti DK40. My old four footer was too small and a junky brand. 6' is borderline for this 33 hp rated pto tractor.

i run a 10 footer with a new holland that has 37 hp at the pto. an 8 ft would be a cake walk. the twin spindles make a huge difference.

I've got about the same amount of HP. Since my tractor is hydrostatic, I would happily run an 8' twin spindle. I think it'd be just swell to go a little slower and mow more per pass. However, as Ozley pointed out, they sure are spendy! When I buy a new cutter, I'll very likely be buying a medium duty 6', because they cost less than half of what an 8' model runs.

It all depends on what you are mowing.

I have an 8' cutter behind my 42.5 PTO HP tractor, wish I had a 10' cutter.

With a HST, you can go as slow as you need.

If you are mowing dense brush, saplings, briars, etc. Then a 6' wouldnt be bad.

But if you are clipping pastures, and nothing too dense, you will find that with a 6' cutter, its not lack of power that is gonna slow you down. Its either going to be 1. Too bumpy, or 2. Poor cut quality as you are over running the blades. Go to a bigger cutter, and you can go slower and still get the job done in the same amount of time. But the benefit is a better/smoother ride and better cut quality.

IE: its preferable to mow @ 4MPH with an 8' cutter than 8 MPH with a 4' cutter. Both will require the same HP to operate, and finish a job in the same amount of time. Heck, even a 16' cutter at 2 MPH.

When it comes to ride comfort, slower is better. But you still want to be productive and get done in a timely manner. thats why I said it all depends on what you are mowing. A few acres once or twice a year, save your money and get a 6'. But mowing alot....think big. You can always go slower or take a smaller bite with a big cutter. But there is a limit to how fast you can go with a small cutter, and no way to take a larger bite if conditions allow.
