Again HP is NOT the issue. And neither is the gearbox rating.
All the gearbox rating does is give you a limit NOT to exceed. And allows the bushhog to be rated for being able to cut thicker brush.
I could use a 6' cutter that only has a 40HP gearbox and only weighs 600lbs, and that would NOT take any less HP to run.
Or I could drop to a 5' cutter, and increase my ground speed proportionally and it again would require the same HP.
I fail to see how it will "wear" out my PTO any quicker. My engine is rated at only so much HP. And only so much of that can go to my PTO. In MY case, 29HP @ the PTO MAX. It doesnt matter how big of a cutter or how small, I am still ONLY able to deliver it 29 HP. And if by doing so causes my PTO to fail, it wouldnt be the cutters fault. Because the PTO is designed to handle the engines power:thumbsup:
Again, thank you for being concerned, but I am NOT. I am mearly after some weights to ballast my front so I can take the loader off with this cutter on. And I think my questions have thus far been answered.
Thank you to everyone else that posted replys relavent to the pricing of weights. I am going to pass on the ones I mentioned. I cant see spending $1/lb when that is what they run new, and there are cheaper alternatives. My nearest tractor junkyards are 2 hrs away, but I will give them a shout tomorrow. It never even crossed my mind to check with them:confused2:
