Backhoes: straight vs curved boom

[roccon31]

because of the over-center design, the case has a better departure angle for climbing piles. ie- if you could climb a 25 degree incline with a jd before the dipperstick and bucket bottomed you out, whereas with a case, you may get 30 or 35 degrees before you bottom out.

from my experience with the larger machines, the case tends to have a faster cycle time when digging due to the design of the boom. that said, i prefer the deere for getting in underneath stuff while digging as the curved boom allows you to be closer to your work.

The over center design is suppose to shift the weight forward onto the tractor. They don't seem to "porpous" as much making it easier to drive at speed.
(I say at speed, 20ish mph is "at speed")

even though I never cared that much for case,,, they do ride much, much better when tramming from one area to another.. And, it is because of what they call over center..

Thanks guys. i'm starting to get the idea.

I thought the extend-a-hoe part is built into the stick rather than the boom... no?

Case has always used this style design for extendahoes. Cat puts theirs inside and Deere's is on the outside. For a time Deere had the rod inside the stick.

Case has always built their hoes to be over the center. It's great for driving and such. The non-curved boom is nice for climbing piles as well...as someone mentioned. It also makes the ride much smoother. I'm not sure if there is a huge difference on transporting the hoe no a trailer. I've never seen a significant difference on how the case hoe rests on the trailer versus the deere or cat. Both transport well. I've used both, don't really care for the curved booms. Everything just seem so heavy. Case's hoes are designed light but with a very strong steel.

Not quite anymore. All of the Cat E-series sticks slide on the outside, so now Case, Cat, and Deere all have outer-sticks.

Oh yes, you're correct. I forgot since I haven't seen a CAT in some time.

I have used both straight and curved, one advantage of the curved is reaching over either a wall or into a container. Cat switched to the outside slide for a thumb, this also helps keep dirt out. One thing I have never thought about till now, will a curved dig as deep as a straight? Fords I have run in the past could reach down almost straight below themselves. I don稚 know if curved would, buts it壮 rare I have to dig that deep.
