i'm looking a getting one, whats the general thoughts? How big of a bucket could it handle in sandy material?
Well a local contractor here has about a dozen of them with 6 yd spade noses on them. I hear thats about all they want.
Yeah I would say 6 yards is the max. My PC600 has a 4.5 yard bucket and a 6 yard bailing bucket. I take it your buying used, Komatsu stopped the 750 series for the new 800, which might I say is one nice machine.
how is this bout a 7 or 8 yrd
That last picture is the reason i wanted one, my dirt pit is really sandy material. the one im looking at has a 12' stick. i was hoping to put a 96" bucket for the sandy stuff and maybe a 72" for the clay. maybe an 8 and a 7 yard. you couldnt find a rock within 300 miles from here.
i also have a 345cl with a 74" 4.5 yard bucket, and its a beast. i would hope that the komatsu would be way better. Is the bucket size regulated by lack of power or lack of counter weight?
It's a lot of things, the machine being able to handle it is of course one, which can be either if it has the power to move it through the ground or enough "rear" to handle a full bucket and lift it. Another big factor is material density and I believe that is how the manufacturer decides what bucket is best. If you're dealing with sand and clay a 7 or 8 yard bucket on a 75-ton machine should be just fine (if you were dealing with a lot of hard shot rock, then you might want that 6 yard spade nose). The only requirement, in my opinion, is to show us pictures when you make your decision:drinkup:drinkup:notworthy
if you're going to spend that kind of coin......komatsu will tell you what bucket you need for the conditions you're in.
well if i were buying new i would most probably get a cat, but my local komatsu salesman is all over me so i think i could get alot of "out of the ordinary" service from them. that store hasnt sold anything over a pc 400. no one around here uses big machines. i do think i need two buckets though, some of the wet clay we have comes out in the exact shape of the bucket. droping an 8 yard chunk of clay from 10' cause the bucket wont fit in the truck wont get me very far, but the main pit is all sandy..
And then add a yard to that number.
