What size pipe did you use for your rear blade’s cutting edge?

[Piston]

I see a lot of you have added a steel pipe to your rear blade. I have an 8’ wide blade at 950lbs using it on a gravel drive.

Is there a rule of thumb for diameter of the pipe?

It doesn’t seem like it would matter too much, but curious what has worked well for you guys that have done it.

At some point if the diameter is too small it will dig into the gravel and you won't get the intended benefit. If the diameter is too big it won't scrape too well. I used a 1" galvanized water pipe (1-1/4" OD) and it works OK on my crusher-run gravel. Would not want to go smaller than that. I experimented with PVC pipe for a couple winters first (worked fine but wore out quickly) which is how I settled on that size.

Matt, do you actually use the blade forward and in reverse? If not, why not just use the back side of the blade? Or do you need the snow to actually curl off of the blade and not just get pushed off to the side? Maybe so if you have a lot of snow to move considering where you live. :confused3:

Re: What size pipe did you use for your rear blade痴 cutting edge?

I don't have a back blade but I did make an edge protector for my bucket. I used 1/2" schedule 40 black pipe. The main reason I choose 1/2" is due to the cutting edge of my blade being 7/16" thick so I figured the pipe would tend to roll and move less if the id were close to the blade thickness. I suspect a blade is going to abuse the edge protector a bit more than I would get on my bucket so my suggestion would be to use 1/2" schedule 80 pipe. I would have used schedule 80 on my bucket if I could have found any around here.

1/2” is much too small based on my testing. The standard cutting edge on a rear blade has about 1/4” diameter equivalent edge. For snow removal on gravel you want to have a smooth rounded surface with some added surface area that doesn’t let the edge dig in (the edge of a rear blade is perpendicular to the ground with some weight pushing it down). 1/2” isn’t much of an improvement. I didn’t start to see good results until I got to an inch or more.

BTW, all of this is dependent on your surface. What works on my crusher-run driveway and exposed aggregate concrete garage apron is 1-1.25", but that doesn't mean anything on different surfaces you folks might have, so take my above comments with a grain of salt. I bet you'd need to go larger than 1" pipe on large gravel (such as #3). Conversely, 1/2" is probably file on asphalt. Whether or not the surface freezes is another factor.

Keep in mind, 1/2" schedule 40 pipe is approximately 7/8" O.D., schedule 80 will be just over one inch O.D. Pipe size is determined by the I.D.

For gravel I can see the benefit of using a bigger diameter. I only plow concrete, pavement and grass.

This is not right. Pipe size = OD (2" is 2" OD etc ) and doesn't change on the OD till it reaches 14" when from then on up it is measured in I.D. just like tubing.

Tubing size is measured in ID size therefore a 2" tubing will be 2" inside measurement and depending on the thickness it will be larger OD progressively as the wall thickness gets thicker.

Correct Brian, I need the snow to roll off to the side. I'm rarely pushing or pulling in a straight line, but rather have the blade at almost full angle to push the snow off to the side of the driveway. I don't truly see the "need" for a steel pipe on my rear blade at this point, as the skid shoes work just fine (in fact, really well) and I haven't had the issue of the skid shoes digging in like some have said. However, I've only plowed my driveway in frozen conditions so perhaps I'll notice a difference in the spring time???

The main reason I'm asking about the pipe size, is my wife has expressed a "slight interest" in plowing the driveway while I'm away, rather than paying the plow guy we use while I'm away. If she does plow, she isn't going to be adjusting the blade nearly as much as I do (I look at it like an art, you know, finely tuning each axis/angle as you leave the perfect surface behind you :laughing She won't do that.

So, for her I think the pipe would be very beneficial. From the sounds of it, it alleviates any need to really 'adjust' the blade aside from angle left and right. I don't want to come home to a driveway that 12" lower in elevation than it was when I left. :laughing:

Not to mention the incredible benefit that I could end up with here. Think about it, if I set up my wife to successfully plow the driveway, she is happy because she did a good job, I make a big deal out of it ("oh honey wow, I don't know many women that could do that" blah blah blah) and she gets her confidence up, leading to more plowing, leading to the INEVITABLE rain/sleet weather starting to come down as she is plowing. Instantly, she will demand we need a cab tractor. BINGO! Like fish in a bucket. :thumbsup:

....and, it's her idea to boot! ("great idea honey..." blah blah blah.... :laughing:
