Should I add a snow deflector flap?

Mostly I think they are needed on truck or ATV plows where you have more speed than what my Swedish Rider can muster up. Even if speed is not a factor, perhaps powdery snow might come up and over the blade whereas the flap might help to direct it out the side. Anyone with a blade on their rider know if a flap is beneficial?

I am however wanting to add some weight to the blade as well so the rubber flap and flat iron bar would do that. If I decide not to add a deflector flap, I might add a piece of angle iron to both stiffen the top edge and to give the blade a little more height. The top lip is only about an inch wide so symmetric angle iron would only give me another inch of height unless I use asymmetric L bar.

I don't suffer from insanity. I enjoy every minute of it!

Re: Should I add a snow deflector flap?

Speed is definitely a factor with spindrift snow from a blade. Unless you regularly plow at speeds over 10 mph, don't worry about it.

A bit of extra weight on the blade will assist it in cutting down compacted tire tracks. I have an extra 150 lb of weight on one of my 5' back blades for this purpose. BUT the back blade is pulled by the cast iron rear axle tubes that can take the hit dished out should the blade encounter an immovable object that it can't pop over and results in the tractor stopping dead. A front blade is usually pushed by sheet metal which can bend when encountering the same object.

Some additional weight would be beneficial for a front blade, but nowhere near the weight that can be applied to a hydraulically lifted back blade. If you have a manual lift for the blade, that will put a severe limit on how much additional weight can be applied. The blade has to be raised many times for each snow plowing event, and your arm will get tired before you're finished.

I have a flap on my blade and I think that it helps to push more snow when we get a 6"-8" snow it helps to roll the snow and adds about 4" height to the top of the blade.

Re: Should I add a snow deflector flap?

Thanks @TUDOR for confirming that speed is not a factor. What about keeping fluffy snow from billowing over the blade? Would the rubber deflector help to direct it to the side?

The blade I am attaching is sold as an ATV plow and I am adapting it to the receiver on the front of my rider. The rider is designed to receive a plow so I'm not concerned about the strength of the receiver. Anyway, the plow has trip springs that should deflect if needed. I'd have gone with OEM but they are wanting $830 CDN for one. So far I am in for $220 plus what I need in iron to adapt it.

I did a clearance and weight test fit and found it to be lighter than the mower deck so lifting it is not a problem. I doubt that a 4 foot length of rubber and/or flat/angle/L iron would really add that much weight to be concerned about but I might have to leave provisions to clip on a few barbell weights JIC. I put additional ballast on the front of my walk behind snow thrower otherwise I have to keep lifting on the handles to hold the front end down which results in a loss of traction. I'd rather put down-force on the handles to lift the cutting edge and in so doing increase the traction on the tires but then snow throwers are pretty useless when it comes to snow packed down by vehicles. Anyway, I digress...

BTW, this is to plow a long country driveway where there are no curbs or manhole covers to snag. Also, it will be one long push with no push-outs midway so the blade has to carry the distance or windrow to the side. Most times the snow thrower will move the bulk of the snow and the blade will polish up what is left or to deal with small amounts that don't warrant using the snow thrower. The wife despises large snowbanks hence the snow thrower that disperses the snow.

When I was retired, I could get out there and clear the snow most times before any vehicles drove over it. Now that I work 10 to 12 hour days, I won't always have the opportunity to clear the snow before it get packed down hence the choice to get a plow and the AWD R322TX. I digress some more...

I don't suffer from insanity. I enjoy every minute of it!

Re: Should I add a snow deflector flap?

It would depend on how deep the snow is I would think. I have found that the only time snow goes over top of my blade is when its quite deep and I am taking that first run at it. After that, I just take half a blade and angle it if it's that deep.
I have a bigger problem with the snow coming out the wrong side when angled. I built this little plate to help with that, since I angle the same direction 90% of the time. Easily pulled off by undoing a couple of bolts

Re: Should I add a snow deflector flap?

Fluffy snow is only fluffy until it meets up with a plow. A tall, heavily curved blade will help with what wants to come over the top, but nothing helps what spills off to the side. This I learned through my teen years using a scraper to clear 3 driveways every time it snowed. For the past 40 years I've used a loader that leaves windrows as soon as the bucket is full, so fluffy snow spilling over the top or out the side is not a problem I catch it the next pass. It's only a tiny percentage of the snow that has to be moved in any event, and not really worth going to any lengths to prevent.

With my loaders, I've straight pushed 250' from the street to my snow dump and then did each successive passes down the same pass line to make use of the windrows to contain the snow from exiting sideways. For your situation, with deeper snowfalls, angle the blade and make the first pass down the edge of the driveway on each side to give maximum width. Then do the successive passes starting from the middle and working across the first cleared pass.

That makes for less side loading while pushing and an extra pass in each direction to clear the full width, but the effort for the tractor is a lot less and it can travel faster.

When I was in the air force, I watched the maintenance crews clear 300' square blocks of flight line in short order using a similar technique. The truck never pushed more snow at a time than what the blade faced on the first pass. The operator spiraled in, one blade width at a time pushing the snow to the outside of the spiral, then busted through the windrows to the outside and did it again and again to push each windrow one blade width closer to the outside edge until all of the snow was at the outside for the snow blower to blow it into trucks and haul it away.

The truck did the whole operation at speed, slowing down only for the corners and as the spiral tightened. He effectively cleared about 70 miles of one lane road in about 4-5 hours by the time he finished the whole 1200' of flight line.

I'm trying to picture this in my mind. The way the top edge fold is on my plow, the rubber edge would stick out front at a downward angle, perpendicular to the curved face of the blade as shown below by a pic I found online. The only way it would add height to the blade is if it were bent up by the force of the snow which I suppose is possible if you use rubber that is not too stiff and not too soft.

Re: Should I add a snow deflector flap?

I learned how to deal with windrows left on the wrong side by the snow thrower. At first I would try to avoid snow spilling out the side by overlapping the previous pass but that just meant many more passes were needed. I found that by deliberately leaving a narrow strip on the wrong side actually left less snow to go back to get than what would spill out by trying to make use of the full width. I'd just grab that narrow strip on the return at full speed and also polish off whatever the scraper may have left behind. The way most walk-behind snow thrower transmissions work, they have more torque in high gear and less torque in low gear, plus in high gear you have inertia on your side.

This will be my first time plowing my driveway so I will have to learn what works best. My only previous snow plowing experience was with a Cat D8 dozer and what I learned there is not transferable.

I also added what I call wings that make the blade wider but if I get to close to an object it has some give without breaking something.

Looks good. Where did get or what are you using for the rubber?

It was a kit came from Amazon. It included bolts and nuts and washers metal bar with predrilled holes and 7' x 6" rubber belt.

I guess I cannot trust my memory... What I said above is wrong. The fold at the top of my blade is actually bent forward at an upward angle, not backward. If I added a rubber flap, it would be angled upward, not down. I would need to use curved rubber such as cut from a large rubber hose or I'd need to place a bent metal channel that would overhang the front lip and fold the rubber down.
