Top O\' the Line Box Blade????

Just got my box blade back from waranty repair. They replaced the square tubing that raises and lowers the scarifiers. That tube and the two arms that support it and let it swing both bent. The tube was bent slightly up in the center and the two arms bent near their pivot points. They bent enough to chip the paint off.

The attached picture is after about 4 hours use yesterday, some of which was in a light rain. No rocks, just dirt. I pull this behind a Kubota L4610HSTC. Note that the left support/swing arm is bent again and the square tube is bent again, just more so than last time and in the opposite direction. Seems like a real quality box blade except for the hydraulic raise/lower part.

My salesman (Kubota dealer) says you should be able to raise and lower the scarifiers while box blading without damaging the equipment. What do Y O U think?

I would have thought so, too, but don't have hydraulically operated scarifiers. I think I'd be very disappointed in that box blade.

Re: Top O\' the Line Box Blade????

I may be going out on a limb here, but it appears that scarifer bar is over rated for the tractor. From what I am seeing on attachments, if you want it to be bulletproof, it had better be rated at more than TWICE the horsepower on the tractor. My little 21 PTO HP Case IH used up a 30 HP back blade in short order. The Rankin thumb on my backhoe was another winner, NOT. I think the attachment builders would be ahead of the game letting equipment operators design this stuff rather than accountants (no offense to accountants, offense to the bosses wanting a good bottom line...)

Re: Top O\' the Line Box Blade????

I think I'd be looking for a refund about now. No reason for that kind of damage, unless you were single handedly trying to lower the Rockies. If they are gonna attempt to repair it again, I would demand larger, stronger steel.

Keep the greasy side down

What brand and model is it, so we can all avoid it. How much did you pay.

Re: Top O\' the Line Box Blade????

May I have the envelope please? Lessee now, the options are: Get it rebuilt back to standard configuration, beef it up, trade up to a tougher unit.

What did the factory say? You damaged this by raising and lowering the scarifiers while using the box blade. Don't do that.

They say, now that their design has failed twice, come to a stop before raising and lowering the scarifiers.

Yeah, right! Next they'll have me in a clean room wearing a white coat and gauze mask with the blade in the air raising and lowering the unit so many micro inches per second. Wonder why they put a hydraulic ram on it strong enough to bend it all to S--t if you aren't supposed to raise it and lower it while in use. Sure could have used a weaker cylinder to raise and lower it with no resistance.

For only a litle over a thousand dollars more I can buy an industrial rated box blade from them. Nice of them to take the old one back at full value, huh?

Cammond, the top of the line!

I offered to be a beta tester for them. If they want to try to beef up the unit, I'll gladly try it out and report back, no charge for my time and inconvenience.

If they don't do something honest and fair over this, I'll give them a few thousand dollars worth of negative publicity. Hell, there factory is only 25 miles from me, I could picket the place. A one man protest march with a giant Lemon flag flying from the bent equipment. Ought to make the TV, papers, and any other form of communications in this backwater since nothing else is hapening. Local radio station has hour long phone in swap meet type shows for folks to advertise stuff for free. That indicates a certain lack of stuff to talk about.

Re: Top O\' the Line Box Blade????

Well, my boxblade doesn't have the hydraulic scarifier option (manual/fixed), but the bar that the scarifiers are attached to is 4" (or 5") square. The one on your unit looks to be less than 2"! Also, my boxblade has a (very large) diagonal brace going back to the back of the box (and up to the top link).

Patrick, that reminds me of when I was a kid in Illinois. Someone had a new Corvette with a lemon painted on the door parked in front of the Chevy dealer. The lemon was lettered to say "this $6,500 lemon was bought from ***** Chevrolet". People walking the street would put coins in the meter so that the car would not be towed. Best I know, the plan worked for that guy.

Re: Top O\' the Line Box Blade????

Glueguy, The square tube you couldn't see in the photo is 4 in x 4 in and isn't bent. It takes the working force as yours does. The bent tube, you don't have the equivalent of, is 2x2 and just raises and lowers the scarifiers.

Re: Top O\' the Line Box Blade????

Latest update pending expected final resolution on Monday:

I volunteered to be a beta tester for their attempts to bullet proof my box blade until one of us (the factory or me) gives up or we succeed. The owner of the company is out of town and is expected back Monday. His staff will meet with him to see what he would want to charge me to upgrade to their industrial rated model. This second option would be just between the factory and me with the Kubota dealer out of the loop. This was all reported to me via my Kubota salesman who is truly a prince among men. It seems both options may be open but I'm leaning toward the industrial model in a slightly wider size. It is a chance to get one hell of a box blade for less $ than I could expect it any other way. I expect it to be significantly cheaper than the difference in the Kubota dealer's discounted prices for the two implements (what I have and what I would end up with). The Kubota dealer gives me great prices, very little markup and no freight (same town as factory in this case).

I'll post the resolution when there is one. Right now I have a very positive opinion of the way they are willing to handle this. My expert and I ASS U ME certain things not in evidence, i.e. I could operate hydraulic scarifiers while blade was in motion scraping dirt. Well no other user has had this problem but I had it twice. Maybe my expectations constitute abuse by there way of thinking. Anyway the waranty is good and they are willing to go beyond it, apparently.

Stay tuned,

Patrick

Re: Top O\' the Line Box Blade????

Patrick -

I've been trying to figure out which stresses are causing your damage, and as near as I can tell there shouldn't be any significat forces applied to the support arms from engaging the dirt. It must all come from from the hydraulic ram. So to get the kind of damage shown in your picture, it seems like the ripper(s) on one side must be binding up or something when you try to raise or lower them.

What I can't see in any of these pictures is how the scarifiers are supported by the lower bar (square tube?) for digging. If they are free to pivot in that lower support, then I can see where there is a lot of leverage applied to the upper one, in which case you'd think the upper one would be a lot beefier.

I know the pict on the left here is not configured for hydraulics, but it gives us a peek at the raised position:

Re: Top O\' the Line Box Blade????

Right Harv, All that and more happened. It sometimes sticks and tries to bend going up, sometimes down. Last time the bend was the other way and milder on the long piece but sharper on the two short pivot arms. This time one pivot got bent but near opposite end of itself from last time. The 2 in square tube is bent more this time and in the opposite direction from the last time. Here is a flash pic I just took showing adifferent view than the two you provided. Between the three, we got it covered. I will probably just trade up for a bit more width and a lot of BEEF.

Re: Top O\' the Line Box Blade????

Patrick,

Do you have the Cammond BS series? If so, it's only rated up to 40hp. All the other ones are already the "industrial" line. I find it inconceivable that this could happen on an expensive product that is properly matched to your tractor. If it is properly matched and it breaks that easy, I wouldnt trust their products at all. I'd ask for my money back...and buy a Gannon.

Re: Top O\' the Line Box Blade????

Harv. I think you are hitting the nail on the head, and the design doesn't apear that it can work, at least not with a ram. If anything, it appears to me the rippers should drop down, and be supported (pushed) in front of the 4x4 steel tube. Also, an A frame on the top side for the hyd. ram to push on would help stiffen that 2x2 tube. Any twisting when being lowered would bind up the individual rippers and bend the 2x2, which is apparently what is happening. Very enlightening.

I hate to say it, but I sort of agree. If anything prevents that whole mechanism from moving exactly up and down in its prescribed path, I don't see how it could avoid binding. Seems kinda iffy for an implement of this type. Maybe I'm missing something.

What I like better (except for the industrial price tag, no doubt) are the industrial boxscrapers by the same manufacturer. They use a whole different approach with "swing away" rippers. They look much less prone to the type of problems Patrick has been experiencing:

2C2_60.jpg


Attached is a better shot of the "swing away" mechanism from my Gearmore catalog.

BTW -- I notice the pictures I've posted in this thread of the Cammond box blades are the same ones that appear in the Gearmore catalog. Not just similar, but the exact same pictures. Only the name on the side of the implement has been altered. I guess Cammond is the manufacturer and Gearmore is just a west coast distributor?

Re: Top O\' the Line Box Blade????

It is Cammond, don't recall series. Tractor specs say I have 39.5 PTO HP At one time, one of these engines, on a test stand, produced 46 HP. With HST I doubt that I am getting over 40 HP to the ground. Anyway it is a mute question, OBE as I will probably replace it with a much heavier sturdier one. There is a 2C2 and 4C2 series from this makekr that are both more heavily built/rated. I'm thinking the 4C2 in 76 or 80 inch size, a bit wider than the 72 I have now. Cover my tracks better. Have wheels at max width for stability and don't want to set them any closer as I have had this thing on three wheels too many times (even on two wheels which I really don't like). The 72 in width was selected partially due to advice regarding small size of tractor. Not having much problem and don't think 76 or 80 inch is toooooooo much blade and it wold cover the tracks of the rear wheels better.

Re: Top O\' the Line Box Blade????

Harv, Cammond does make the Gearmores. I spoke to Gearmore, who told me they have no dealers outide of California, Arizona and one other western state. They gave me the name of a guy at Cammond, who confirmed that Cammond's 2C2 series is the same as Gearmore's 2G2 series. I think Patrick has the Cammond BS series, which to me is a light/medium weight, low/medium end box retrofitted with a hydraulic scarifier mechanism. Cammond quoted me 1600 plus freight for a 2c2-72 (fixed blade) and 1700 plus freight for a 2c2-72T (hinged back with locking pin). I dont know that Gearmore picked up both the fixed and hinged back models.

Maybe you can pick up a Gearmore hydraulic unit out there for me, and Mark Chalkley can bring it back east when he returns from delivering his tractor to you.

Sounds like a perfect plan to me, Glenn. I'm sure Mark is about to reconsider my offer, so I'm going to go sit on the porch and wait for him...

Re: Top O\' the Line Box Blade????

I've pushed and pulled this apparently "light duty" box blade as hard as the L4610 in low or medium range at PTO speed in 4wd is capable and can't phase it in any way except the hydraulic raise lower scarifier function. I've been told here on TBN it looks really light duty with thin metal and no braces where other units have braces B U T it remains plumb, straight, true, unbent and in fine shape except for the hydraulic raise lower part. I think the box blade design is a good one and is mature, having probably been evolved over time to its current quite successful form and doesn't need the braces or heavier metal. However, the hydraulic part just might be an add on that hasn't evolved to a bullet proof form.
I sure can't fault the box/scraper part. I back into dirt piles at warp 3 to use inertia to move them when I couldn't possibly move them in low range 4wd, no problem. I really work the heck out of it and it just performs really well, especially now that I have learned to use the hydraulic top link to dump dirt rather than the 3ph (I got no instruction manual or training, just went for it. I have been observed of late by an old timer and he says I'm doin' just fine but was a bit surprised by my agressive style, especially tilting the blade. Anyway, I am most dissapointed with the hydraulic part and the difference in cost between this unit and the 2C2 is about $1000 retail. The 4C2 is another $200 up from there. Still, I like strong. If the factory offers a good price consideration, something much better than the retail difference, I'll just bite the bullet and get the 4C2. I like strong stuff. I will not baby a pile of steel. I may treat the tractor a lot better but it is a tad more sophisticated than just several hundred pounds of steel in a low tech configuration.
Anyone have thoughts on width? I am having no difficulty in 99% of instances pulling the 72 inch with box at maximum scraping adjustment and scarifiers fuly lowered. I can do a good job with just the scraper in medium range on the tranny and in softer dirt medium is ok for scraping while scarifying. I would assume that I could go up a bit in width and get better coverage for my tire prints without overloading the lil Kubby. They have 76 inch and 80 inch.models. I don't think the 76 would be a stretch but would like the 80 if that isn't unrealistic for a L-4610 4wd with HST. As this is my first tractor and box blade I have no experience to draw upon but the advice of others. I feel more comfortable hearing the pros and cons discussed here than relying soley on the manufacturer and or dealer. Info learned here has prepared me to better understand and participate in decisions made in consultation with the dealer.

So, what do you experienced box bladers think? My Kuby is rated at 39.5 PTO HP (46 at flywheel on a test bench, ever do much farming on a test bench?)
