    The front (high end) of the skid shoe is the front of the BB (gee, I don't think I said that very well.)

    If the skid shoe is behind the cutting edge, wouldn't the blade just keep going deeper, since the shoe would be relative to the cutting edge and it would go up/down as it wished, since they were always in synch.

    Note that a lot of the stuff I build is one of those "Forehead Slappers--like duh, you should have seen that coming Ron!"

    My plan for the skid shoe would be for it to limit the depth of each cut. For example, if it were set for -2", the cutting blade could go down 2" (not allowing for 'sinkage'), the shoe would contact the uncut ground, and then would float the cutting edge at that depth...........)

    I think if it worked as I hope, it would allow me to control the cut better.

    Would like to build it tomorrow; however, gotta shag one of my vehicles home from 200 miles away.......... and take son back to KOLLIG, and meet daughter in another city........ Will be a LONG day on the road. (Maybe I can design something else in my head that Henro can drill holes in!)

    Have a great weekend.

    First take my comments with a grain of salt, because I might be seeing things wrong.

    It seems to me there are two points to consider. The ends of the lower lift arms, and the point where the skid shoes or gage wheels would touch the ground.

    The lower lift arms are fixed at wherever you set them.

    The top link length will set the angle of the box blade. The pivot point is the point where the skid shoes or gage wheels touch the ground. By this I mean that all things being equal, you can only adjust the top link, and doing so changes the point at which the gage wheels/shoes touch the ground.

    The net effect is that the angle of the cutting edge is related to the elevation of the lower lift arms and the extension of the top link.

    Cutting angle is greater if the lift ams are lower and the top link shorter.

    This is my experience, learned from my landscape rake rather than my box blade, as the box does not have gage skids/wheels...

    Hope this make sense...

    It is the way things work for me anyway... [img]/forums/images/graemlins/smile.gif[/img]

    Henro, you been hitting the bottle again [img]/forums/images/graemlins/grin.gif[/img] [img]/forums/images/graemlins/grin.gif[/img] [img]/forums/images/graemlins/grin.gif[/img] [img]/forums/images/graemlins/grin.gif[/img]??? Just kidding.

    I think what you said makes sense, especially starting in para 6 of your note.

    Hey I don't dispute any of what you say. You might be 100% correct. What I'm hoping for is a way to limit the deep cuts my BB currently makes. It's size, plus the short wheelbase of the BX, uneven ground, and my inexperience, makes for less than favorable results.

    If I can limit the cutting depth with some homemade skid shoes and improve my BB performance, great. If not, I need the welding practice anyway..............

    Either way, I'll report back, even if they fail miserably.......

    Have a great holiday.........
    Ron

    Here's my 2 cents. When you make the adjustment holes, drill them "erractically", taking the idea from the kubota lift arm stabilizers, so that you have a lot of adjustment, by just lining up whatever hole fits for the height you want.
    Maybe "offset" would be a better adjective, but neither really fits.
    I have thoughts of the same thing, but maybe with some kind of hole for mounting the skids on, and having some casters that could be used instead, fitting the same holes, if the job requires wheels instead. You could probably use some finishing mower casters for this.

    I guess for me the question would be whether to mount them on the sides at the back or on the back. I guess this depends on how you are going to use it, but I'd like to hear others' opinions on this.

    OK, I know this is over 5 years old, but gauge wheels, skid shoes and box blades are kinda perennial subjects.

    Here is about what I think the O/P was having trouble with.
    A HEAVY box blade behind a light tractor, digging too deep.
    I think he was looking for control of the depth of cut and assuming that gauge wheels would somehow add control.

    Couple of points;
    A box blade does NOT convert a tractor into a dozer.
    However much depth control you have if you try to cut an inch deep you will QUICKLY pile up and flow over the top - IF your tractor can even cut 1 inch and carry it.
    I think a 6ft box blade probably makes a good anchor to a BX2200, but that seems to be what he has (had 5 years ago).
    There is a HUGE difference between the power required to cut an inch deep and 72 inches wide vs chiseling six one inch or so wide scarifiers through the soil 4 inches deep.

    What I think would work in this case is to put the scarifiers down and keep the cutting edge JUST off the top for the first pass.
    Basically do this at least over the highest areas until some top is loosened and available to be spread.
    THEN retract the scarifiers and try to get the blade down to only move the loose top stuff - no CUTTING per se, just pushing the loose stuff around.
    Try to keep the box about 1/2 full, it will vary as it gathers from the highs and distributes to the lows, but on the flat try to carry the box about 1/2 full.

    First thing I did to my box blade was add guage wheels. Mine are controled by a hydraulic cylinder to raise and lower the blade. I think this modification made the BB a lot easier to use for any leveling projects. I can remove my wheels by removing the cylinder and two bolts, but I have yet to find a reason to remove them

    Another thing that keeps coming up is the tendency of a rear attachment to DIG when the tractor's front wheels go up a bump and of course to lift when they go into a hollow.

    This is why posters want to float the implement and have it guided by gauge wheels or skid shoes.

    Looking at a typical tractor's lower lift arms it would seem that a better pivot for a rear blade or box blade would be at the FRONT end of those arms, not the REAR end.
    That would keep the blade much closer to a consistent depth/height relative to the rear axle and only SLIGHTLY affected by vertical movement of the tractor's front wheels.
    Not easy to do, but "would be nice" (-:
    On second thoughts; quite easy to do and probably worth it.

    ================================================== ===

    Here is something loosely related;
    I will probably make or buy a skid steer to 3 point adapter in the near future.
    There are just times when it would be handy to be able to use say a rear blade to pull some dirt back into a hole, but the hoe or phd is already on the back of that same tractor.

    Anyway, looking at a landscape rake that I have with gauge wheels I was thinking how well THAT would work on the front.
    The geometry looks favorable, in float it would be on a long arm pivoted just behind the tractor's front wheels and of course dump/curl provide the same function as a hydraulic top link.
    I might experiment on snow (-:
    If that works I will probably put very small gauge wheels on the blade and have them very close to it, not out on extenders WAY behind (or in front of) it.

    Leveller,

    Would you mind sending pictures of your gauge wheel setup? Sounds very interesting and something I may be interested in doing in the near future.

    Thanks,
