Has anyone here added steel to the sides of their box scraper to make them a bit thicker? Was considering adding either 1/4 -1/2 plate to the side of my 1/4" thick side plates. Also, how risky is it to use a BB with scarifers down to rip up a field that may have decent sized rocks in it? Anyone have bad experiance with hittting a rock and it not moving out of the way for the scarifers? What happens?
Thanks Brokenarrow

I have VERY rocky "soil". I use a 5 ft heavy duty BB,
and to get any ripping action, I pull out all but one or
2 of the rippers. When I catch a rock that does not want to
move, the tractor stops IMMEDIATELY. No damage. Your TC40 is heavier than my L2550, which weighs a total of about 4500
lb with loader, BB, and water in the tires. I am in first gear of course, so I am not going all that fast. ....

Why are you adding steel to the sides of the box? I've never thought about it.
Many times I've hit rocks with my rippers that stops my TC29. It'll jerk a knot in your tail. Never has hurt anything, but with your bigger tractor, you might bend something on the BB. Now backing into things, even my tractor will bend the 3ph mounting on my TSC box blade.
I guess the best thing you can do is to go slow. I think my BB is the most useful implement I have.

I've hit lots of things that just simply stop the tractor without any damage to the box blade. Possibly I don't understand a special circumstance you have, but I think adding two sheets of half inch plate would be overkill and just lots of extra weight to lug around. Best of luck. Frank. ....

You might want to add weight if the blade won't cut the ground but that's the usual reason for using scarifiers. It'd be unusual ground if the scarifiers won't loosen it up. Adding weight would make the blade cut better but it'd also add to stress on the box frame and 3ph mounts. It'd also increase the shock loads when rocks are hit.

Going slow and lifting the box in turns is good and also avoid going up steep grades if there's a chance of hitting a rock. If you're looking for problem rocks, making a pass with the blade held off the ground and using the scarifiers only will find them. If the top-link is extended it would tip up the scarifier tips so they'd lift over more rocks. ....

I was thinking that adding to the side walls would help beef it up. Dont it slide on the sides and arent they like wear plates? Was thinking a bit thicker than 1/4" would help wear qualitys? I see some have thicker sides 3/8- 1/2 and alot of them have only 1/4"?
Also I was planning to use just scarrifers to rip up and loosen the soil in a field I just killed off. I need to go down 4-5" and dont want to pull up any rocks from farther down by plowing. I had brassicas in this field last year and it grew back in more weeds than clover (since I did not controll the weeds last year before I planted) So I want to loosen up the soil so I can run my disk thru it to prepare for my fall plantings. Was wondering if hitting any larger rocks would damage the tractor? I can always buy a few extra scarifers.
Thankyou ....

I went out looking at different Box scrapers today. There are a few minor differences in the brands (from what I can see most can be made to look like the more expensive ones with about $50 worth of steel and a welder.) The more expensive ones have 3/8 sidewalls (that I looked at anyway) and a shim behind the scarifers. Anyone here know of any other differences? The hook up is much cheaper (made) on the KK's but like I said for about 50 bucks it can be changed.
Have any of you wore out the back blades on yours yet?
How many inches below the blades can your scarifers be adjusted to?
Thanks ....

I think replaceable blades are one difference. 3ph mount design is another. My dealer turfed one line due to 3ph mount failure in several he sold. I think my scarifiers go 6" - 8" in depth--more or less depending of the box tilt. ....

I have owned several box blades...all were quite simple
with about 3/8" sides, which are called heavy duty. All use
reversable cutting blades, fore and aft. I notice one key difference, however. Some of my blades hang the cutting
blade a couple of inches lower than the side plates, the others mount them flush with the side plates. What's up with that? I have seen pictures of BBs with hinged backs. I
assume that is so you can go ripping without dragging a
bunch of dirt with you?

One final thought: a heavy duty 60" blade (about 465 lb) costs $600-800 here on the left coast. I have been shipping them in from back East for less than $500 including shipping. Outrageous. ....

I think my blade is flush with the plates. I have noticed that the plates can interfer with cutting when the box is rolled up for heavy cuts. Similarly, the fronts of the plates come off the ground a bit when the box is rolled down enough far enough for spreading. I think flush blades would be better for spreading and lower ones better for heavy cuts.

A hinged rear cutter is mostly for heavy cuts. The rear cutter can swing up to allow the front cutter to go deeper. They also may be a bit better at spreading. ....

If the goal is to reduce wear on the side plates I think it would be easier to add some angle iron to increase the surface area. Bolting lengths of angle on instead of welding would make changing them easier if they wear down. If you just want to add weight I don't think a couple of plates that small will make much difference in the greater scheme of things.

Best of luck. ....

The difference in wieght between the one I was looking at and the NAME brand one is only 45 pounds. I figure the difference comes into play with the side plates being 1/8" thicker (17"x24") times 2. Yes, I think a better option would be to bolt them together using my electric mag drill. I do see that the cheaper model has a less rigid system for hooking to the top link and swing arms, although I dont see $350 difference in material and workmanship. also the scarifers are mounted a bit different with supports behind them. Again, $350 bucks wont break me but its point sometime I guess. The cheapper KK is $365 and the woods I priced is $700. Almost 2 for one? This is the part that makes me crazy.
If I were in buisness with it no question what I would go with but since this is a hobby and the "ceo" is keeping a close eye on my spending I need to be frugal (cheap).
Thanks for your ideas fellas
TOM ....

Tom, your logic is sound, even if it's only inspired by fear of the boss's critism, LOL.

I wouldn't be concerned about the strength of the sides, an 1/8" isn't going to make much difference.

As for the hitch, you should look around at 'junk' in the back row at a dealer, or a farm equipmentwreckers. It's often easier to slice a good used hitch off some big old implement and weld it back on to something else than re-invent the wheel.

Best of luck. ....
