New Brush Cutter

[AVIVIII]

The previous owner had put new wheels on the good 90" deck and the flail mower and PT provided a similar setup. Hard plastic wheels on the back, and semi-solid, non serviceable, smooth, balloon-ish tires on the front. My other 90" deck has all 4 inflatable tires; that are all flat.

I have had the blades spin around 180 degrees from normal back over the drum. Once a blade went so far it got stuck over the head of the bolt holding the opposing blade. She shook a bit! My blades are pretty ragged out and I should have Terry send me a new set, but i'm still in very uncharted territory and don't want to start smashing new blades off of rocks I haven't 'found' yet....

I've heard them called stump jumpers, I think.

The rotary cutter on the AG tractor has a stump jumper, but the blades are offset so that they cut close to the height of the stump jumper. If I was to bolt one onto the PT deck, it would hang way lower than the cut level.

Yes. I've looked into putting the gull-wing style blades onto my PT drum on the brush cutter, but then they'd hang down too low. So, I'd have to measure the distance, trim down the height of the drum, and cut off a length of the shaft to the lovejoy to compensate, but, I believe it would be a very good modification to see if I could use more standard blades from stock at Rural King, TSC, Amazon, etc...

They'd swing under the corresponding blade's mounting bolt head, and that would greatly eliminate the main problem with PT's design.

Something like these 18" King Cutter blades....

It looks like all that you would need is a deeper skirt, and raising the deck.

I've thought about that, too.

I think it would be less cutting and welding if I just shortened the shaft and drum VS lowering the wheels and adding material to the skirt.

For that matter, I may look at getting the drum for a standard brush cutter, too. Then I'd just have to adapt it to the shaft. Anyhow, a good winter project.

I am all eyes and ears! This project sounds great! One thing about this new one I got; even though I have the deck raised as much as it can be, it still cuts way too low. Probably less than 3?

 

[MossRoad]

Yep, mine cuts pretty low, too.

LOL. It'll happen. Every spring my pasture "grows" new rocks, and my brush cutter happily decapitates them and sends them flying a few hundred feet.
