Opinions Please.... I'm building a Brush Hog.

[RS Coyote]

I have a 863G and I'm going to be building a brush hog for it and I will post pictures when I'm done. I have a damn good design thought up. I will be using this for clearing brush and sticker bushes. Now should I build it 72" wide or an 84"wide? Pro's & Con's? I'm thinking of going with the 84".

myself I wouldnt go much bigger than your bucket if it gets too large you may find it hard to manuever also a smaller one would have better power (less loss to rolling resistance or drag from heavier parts) but I may be all wet perhaps someone with more time with a brush hog may have more input happy fabricating Jeff

Thanks for the reply. I'm looking at parts right now to build 78" High flow. Anybody else?

I would go at least as wide as from outside tire to outside tire. My tire width is 71" and I only have a 60" Brushcat. This makes it somewhat difficult in heavy brush, but not unbearable. You auxillary hydraulic flow and whatever hydraulic motor you get will utimately determine your maximum diameter. You need to have enough power and speed to keep the blades turning in the biggest brush you want to cut. Heavy blades will have more mulching power, but will also take more hydraulic power to spin. A larger diameter blade pattern will have faster blade speeds at the tip than a smaller diameter, but will have more rotating mass and the long blade will slow/stall your pump easier. You are planning direct hydraulic drive, correct? A larger diameter will also put the weight further in front of the machine and may cause tipping.

Quote"You are planning direct hydraulic drive, correct?" Not at this time. I don't know where to get/order the proper Motor and blade assembly. Do you?

I ordered about $2500.00 in parts today to build a 72" Brush cutter. I'll post pictures in a couple of months after I get it built and know it works along with some details.
