Mohawk brush cutter questions

[MoPops]

I bought a old 5' Mohawk brush cutter. It came with a three foot PTO shaft, when I first hooked it up to my Bobcat CT225, it was very apparent the PTO shaft was too short. The guy (junk dealer, I'll call him) I bought it from is going to extend the male portion of the PTO shaft by 6". I think that would be enough.
Question, I noticed (I'm a total rookie at all this by the way) that newer PTO shafts are enclosed in a cover. When those shafts are rotating, does the cover rotate also?
I can certainly see the safety benefits.
Question, can you buy the cover separately, and get them to fit over a older PTO shaft?
When I test ran the brush cutter, with the too short shaft, I could see and hear the shear pin plate hitting the arm for the brush cutter that goes up to the upper arm of my three point hitch, when I lowered the three point hitch down, the arm angle changed, and wasn't hitting the shear pin plate. However, it forced the rear wheel on the brush cutter down hard on the ground.
If I wanted to knock down taller brush, and not cut real low, I'd like to run the brush cutter up a little higher (I think) the only way around this plate hitting the arms was to raise the arm going up to the top arm of the 3 pt hitch. I haven't tried it out yet, as I haven't got the lengthened shaft for the PTO yet.
So, the question is; does the rear wheel of a brush cutter need to be on the ground?
I didn't think so, but I'm not sure..
Sorry for the lengthy post. I hope I've explained the situation with the knocking and spinning of the PTO shaft and shear pin plate well enough so that someone can understand what I'm asking.. :confused2:

Thx

As far as the shaft goes, I'd consider getting a PTO extender. I use one when I have my quick hitch installed. It adds about three inches -- the amount neccesary to compensate for the quick hitch. I suppose you could add one to both ends, if the splines are there on the brush cutter, for a 6" adjustment.

Also, the plastic shield should not rotate with the drive shaft. There should be small chains to keep it from spinning.

If you get a longer male shaft, make shure that at least one third of the overall length is overlapped.

I believe the 6" extension will make it work. Do you know if you can buy the protective covers alone? Is there any trick to finding one that will fit?
I believe I'll need a 36" cover.
Thanks for info. Just having the cover in place, and not spinning has to be worth some peace of mind.

You can buy the covers. Look at Tractor Supply or Agri-Supply. If you need 36" and can only find 48", you can hacksaw it to the right length.

How about question #3, which was hard to find in such a lengthy post..

"If I wanted to knock down taller brush, and not cut real low, I'd like to run the brush cutter up a little higher (I think) the only way around this plate hitting the arms was to raise the arm going up to the top arm of the 3 pt hitch. I haven't tried it out yet, as I haven't got the lengthened shaft for the PTO yet.

So, the question is; does the rear wheel of a brush cutter need to be on the ground?"

I've attached a photo that shows the top portion of the brush cutter. That wide section (I've been calling it a shear plate) was hitting the arms running to the top arm of the 3 pt. I removed the bolts and moved it from the lowest setting to the highest..

This adds 6" for $20. Looks like a great way to go to me..
Thanks!

Looks like a 3" addition. 6" overall length. I get it.
