Which grapple?

[ArmyDoc]

Might want to have a look at Faver's grapples. grapple rake | Faver Inc

They use AR400 steel for their tines, one inch thick. AR400 has 180,000psi yield strength and ~ 400BHN hardness which is the highest I've found being used. Prices seem reasonable too.

No problem. The grapples that I have won't be ideal for your tractor. The little Gorilla Grapple that I bought to pick up cut off cedar trees is 44 inches wide, 31 inch opening and weighs 946 pounds:

The Monster Grapple That I use for picking up dead tree limbs, weighs 1168 pounds and opens to 51 inches:

Can't do this with a clamshell style:

So, if you could only buy one, would you get the narrow one or the wide one? Which one do you use the most?

Also, do you see an advantage to having two lids, or would one center lid on the wide grapple work? (I'm thinking one wide lid would likely twist if clamping a load wider at one end, but a narrow single lid in the center i would think would be ok... or am I not thinking right?)

Wide one. I Use the wide one most because of the 51 inch opening, here it is picking up 30 cedar trees: http://www.tractorbynet.com/forums/...ppling-fun-picture-thread-19.html#post4343409

Picking up some cedars pulled with the tree puller, can't do this with a clamshell style:

For my uses two lids are an advantage, but a narrow single lid will work for most things.

When I move long trees with the either grapple I balance it and leave the lid up.

Here is one on the narrow single lid:

Here is one load a single lid wouldn't secure:

Dont see any weights on their website.

But dont think I'd want to spend my money on a grapple built out of 1" thick AR400 plate for a mere 50 HP tractor.

What good is a grapple on a 50HP tractor if the grapple itself eats up 50% of your lift capacity?

Lol. Excellent point LD1. I was actually replying to Case 580c's post on page 4. He was asking about a grapple for a large Utility tractor. I should have quoted him to make it clear. The weights are listed on the specs page. For the GX series, they start around 600#. The X series is over 1000#

Is the width more important, or the opening?

I've been looking at this one: Home
It's got a 46" opening, and is 56 inches wide

Alternative might be: Home
It's wider at 72" but the opening is only 42 inches

Other options are more expensive than I wanted to spend.

Since my need for a grapple was primarily moving logs, I went with a forestry grapple.
Sundown GR40 Forestry Grapple. While designed for logs, it still seems to work pretty well for grabbing piles of brush. It's not good a picking up things like 16" long firewood or small rocks, but that wasn't what I was looking for.

The Frost Bite Grapple is very similar

i think it would be useful to point out that virtually no tractor of less than 150hp would come close to needing a grapple made of AR400 much less 1" tines. That type of grapple is appropriate for LARGE skidsteers. There is no 50hp tractor on earth that really needs more than 3/8" mild steel for a grapple. Think of what the standard bucket for any tractor is made of. No need to go much beyond that type of steel for a grapple. A bucketful of sand will weigh as much or more than any load a grapple will lift. Think also about a tractor style FEL: NOT designed or built for ramming/bulldozing. Tractor FELs are for lifting/loading and are therefore relatively long and thin. Bulldozer arms are short and stubby for a reason.

Both width and opening are considerations. I much prefer a wide opening. 40+ inches is best. Width depends on what you are trying to do. Narrow (48-60") works well for almost all typical tractor grappling tasks and makes maneuvering easier as well as giving you a larger net lift capacity and being less expensive. Narrow is much better for digging. Wide is appropriate for some very specific tasks like moving cut firewood or trying to move more than a single bale of hay at a time.

Where I live I have a Kubota B21 with modest lift (926 lbs) I mostly need forks and occasionally would like to move branches, brush etc. I am looking at:

#84 Dbl Cyl Fork Grapple | MS Attachments

Where I would leave the lid on to move branches, brush and lighter fork loads. I hope to build firewood crates at which time I would remove the lid and cylinders during firewood season. I will need to call mid state to see what the forks and brackets weigh without the lid. The B21 is the perfect size for around the house and I hope to be able to manage to lift a decent enough sized firewood crate to replace my current wheelbarrow in the rain method of moving wood.
