I've got a problem that I'm a bit unsure how to "fix". The previous owner of the 763 I just bought routinely used the bucket without a bolt-on cutting edge. The result of that is that the front lower edge of the bucket is rounded upward and worn back almost an inch. Naturally, this results in a bolted-on cutting edge being at a positive angle to the ground with the bucket level... Does anyone here have a suggestion for remedying this situation short of replacing an otherwise sound bucket?
Thanks,
Ken

Sounds like you need a new edge , You can buy the weld on edge from Bobcat , it is preformed to make the curves on the ends , the holes are drilled if you ask for that type , you cut off the old one then weld the new one on , the bolt the edge to it , before bolt on edges that was the only way to repair a worn out edge , I must done about 50 of the weld on type , a plazma cutter or arch gauger makes the job easier , but a torch with a gougeing tip will do just fine , use at least 7018 DC rods when welding it back on

I hadn't realized that Bobcat had the repair parts. Can you tell that I'm a little new to this?

I just ordered a weld on cutting edge for a grapple bucket I'm building. 73” X 6” X 3/4” it was $160. plus shipping $45.00 www.colemanequip.com 913-422-3040
It was cheaper than my bobcat Dealer. dennis
On a grapple the cutting edge is flat and you can use any flat edge to repair , the one from Bobcat to fit a bucket is bent to shape on both ends and makes the repair solid and has the holes in it to bolt the extra edge onto it , you can get some flat edge with holes in it and cut the bends of the old edge and make it all work out

i never use the bolt on cutting edge, when i'm picking up broken concrete the last couple of pieces will not get into the bucket , they keep running into the bolts and you end up chaseing them all over the place or you have to get out of the machine and throw them into the bucket by hand. i use a local cutting edge supplier ,he sell teeth from bobcat size to dozer size and any size cutting edge you want. for the ends i just cut a piece the size i want and weld it on ,no need to get the special bobcat edge with the bends. i get about 500 hrs out of a cutting edge and it takes about 4 to 6 hrs to R&R the edge , thats machine on the trailer to machine on the trailer. i usualy make the ends 4 inches tall that way when i grade to a string for flat work i know if the edge just fits under the string the grades just right....

How do you remove the cutting edge? The last one i did i cut the entire floor out as it was buggered. It took me around 2 days to replace the 2 cutting edges (4 in 1 bucket) and re-weld in a new floor. I ended up using a demolition saw to cut through it was that hard!
My plasma cutter is only rated to 16mm but realistically it will only cut 12mm.

Time is money , and down time is double , the cost of time lost and the cost of time put in , 4 to 6 hours of my time is worth 400-600 dollars , after adding in welding rods , oxygen and acc., it is not worth not using a cutting edge , for if you change in when needed you will never have to weld it on , the edge can also be flipped 1/2 way thru and wear the other side making t lst longer , not being mean but maybe those 4-6 hours could be used for operator lessons for the edge isn't whats stopping getting all the debree off the ground and into the bucket

Coleman Equip. has the one with the rolled up ends. I'm sure you have a 6 in. wide cutting edge. You can get a new one tha is 3 in. wide and replace that part on the old one. If your doing it yourself it's cost effective.

tazza.. i have a bigger plasma cutter than you do...i just cut right thru the weld and the cutting edge from the top ,then gough out the rest of the welds,follow up with cold chisles and a 5lb hammer. i've never done a 4 in 1 bucket ,like you say they never caught on here in the states . a buddy of mine bought one a long time ago ,it was a factory prototype he liked it well enough but it was under built. when he used it to back drag with the edge open it bent the edge over time ...then the bucket wouldn't close up tight...it sets in his yard and he's back to regular buckets. fishfiles.. every bolt on cutting edge i've seen has nuts and bolts sticking up in the bucket, your telling me if i had 4 to 6 hrs of lessons i could get concrete to learn to jump over those bolts, that last couple of pieces in the parking lot slide up the edge hit those bolts and don't want to go in unless you have something to push them against...even if you have something to push against if they hit just right you have to give them a good push. time is money but i've been in the bobcat for hire business since 1978 and it's still a rare month when i don't have half a day or so off for maintenance. if a guy is getting 100 an hour and can work all of the daylight hours 365 i not sure it even makes sense to stop to change bolt on cutting edges,just have the dealer bring a new bucket by the job....

Ive found that stitch welding prevents warpage in an old/thinnish. bucket . and make sure that the edge is flat on the end of the bucket as its easy to cut/weld one on at a slight angle witch makes flat work not so flat.......and i don't really like a bolt on edge myself either. ....Jeff
