Traction Brush Hog on GC series tractor

[somewhereinusa]

Years ago I bought a 4006 Deutz, 35 HP. It came with a 4 foot bush hog. I was disappointed in it's performance, anything very large slowed it down way too much. I put the 5' rotary mower I already had and it made all the difference in the world. I can only surmise that the extra flywheel effect made the difference.

So I was able to test out the 5' John Deere 205 Gyramor cutter and almost to my surprise it was an absolute success. ...


After trying to negotiate a fair price with my uncle he gave me a deal I could not refuse...the good home family discount of free!

She'll now be retired to my garage for a bit where it'll get some parts, routine maintenance and a fresh paint job! ....

A full-blown success story if I ever heard one! Glad to hear it. Give us a "rest of the story" after you paint it and gussy it up a little.

Esp on an older hog like that watch the gear box lube (and I think I mentioned before, use the "double zero grease" instead of 90 wt gear oil if the seals are leaky. Also make sure the shear pin is tight and the right size, meaning very nearly a force-fit.

Here are a couple of pictures of the 4ft JD 413 that I use on a B2150 Kubota. The price and mode of purchase in my case were about the same as yours. From a cousin... [a 5ft Bush Hog brand I use on another Kubota B2150 cost me $1000.]

Hey there Somewhere... Do you mean that "trying to cut anything very large" slowed the 4ft mower down way too much? I'd have to guess that something was retarding the 4ft unit rotation speed (like wire or twine around a shaft or bad bearings or who knows.) If the 5ft unit had a MUCH heavier construction stump jumper and as you say a "heavier flywheel" effect it would sail thru momentary heavy stuff better but not a steady diet of it. However, if both cutters were on equal footing with no binding or restrictive debris or bad bearings, the the larger cutter requires more HP to run it for sure. No way around that. Like in heavy grass or light brush that is long-term, not just a clump here and there.

There is also the possibility that the 4ft unit you found inferior was a different design with different gearing and maybe just an inferior hog compared to yur 5 ft unit (?) Maybe the smaller one had a bar type blade carrier and the larger one had a heavier stump jumper ?

I have to look up fluids for this unit at a base level. There are no seals leaks or signs of seeping lubricant anywhere. I'm already having some issues finding new/replacement shoes for the bottom. New blades are at the ready. I'm also in luck! This unit uses a built in slip clutch system, not a sheer bolt.

Very possible, I only tried that 4 foot mower once and it was a long time ago. If I remember correctly the small one was Bus Hog brand. The 5 foot one, which I still have, is a King Kutter.

Good Morning folks!

Has anyone been using a 5' brush hog on a GC series tractor routinely? I would typically go for a 48" or even a 54" if buying new but I have a 5' that is available to me via a family member that acquired a newer, larger more industrial cutter for his 2 farm tractors and isn't in need of his 5' he has sitting/rotting in the weeds any more.

It's a John Deere 205 Gyramor, a real antique, but is in fair working order. I could probably go hook up and test it on his farm but wanted to see what other people are experiencing before packing up my GC1710 and taking the 45 minute ride for such a test. Any real world input would be much appreciated! Thank you.

Ive seen them running 5 footers easily on youtube. One guy had a brush hog squealer 5 foot and was running it on idle in thick weeds. So yes you can-however.....if your going to run it for long periods of time you need heavier duty cycle tractor. HP isnt everything its a tractor that can work under heavy loads for long periods of time so they dont overheat.

My dad has a 36hp kioti and while it will run his 6 foot brush hog it will get super hot in his field after 40 minutes. He uses an old International diesel (1980s) two wheel drive 35 hp that will run the brush hog all day and beg for more.

I mowed for 3 hours at full throttle to achieve the 540rpm PTO speed and it ran cooler than when I run a 4' king kutter offset tiller.
