Observed a blizzard plow tripping

    I just got home from a sandwich shop for lunch where a guy was plowing the lot with a Chevy 1/2 ton and a newer looking blizzard plow. There was about 1 inch of snow/ice/slush on the lot and I watched him plow the lot. Now here's my point/question: Every other push (maybe 75ft long) the blade would trip and fold right over. Is this common with full trip blades? I have zero experience with a full trip, but after seeing that I don't think I want to experience a full trip. It seems like it would be very annoying not to mention not very productive because every time it tripped he would spin his tires (he was in 4x4) and have to start the run over. Do you guys experience this alot? And no, the lot was not icepacked or anything.

    The only reason I can think of for the blade to keep tripping is that he is hitting solid pack ice, or pot holes in the lot. I have a full trip western, and meyers, and neither one of them trip very often, unless I hit one of the above, or a lip in the pavement from an apron of something like that.

    The trip point can be set. He probably has it set too light.

    I liked my full trip plow. There was no mistaking that the plow was up against something that could cause damage when the entire blade starts folding down.

    The springs need to be adjusted. This is just starting to happen on my Western Pro. It is not that uncommon. I've done this adjustment dozens of times over the years. You can't always go by the recommended gap setting of being able to slip a business card or credit card between the spring coils...that is just a rule of thumb for NEW springs. As they wear and get softer, they have to be tightened. LOL...I had to laugh this morning...As I was piling snow on a strip out by the road, I ran up on to the pile (frozen underneath), and when I reached the top, the blade tripped a bit and literally THREW snow quite a ways wit the bottom of the plow when it tripped back. I just thought to myself..I'm glad there wasn't a CAR right there!:p

    The springs are either getting weak from tripping too much or just need adjusted as mentioned earlier. I prefer compression springs for this reason whether its full mold board trip or trip edge. Compression springs never stretch are rarely weaken or break. Think about the coil springs on cars or trucks and how often they wear out even being driven daily. Put the same idea into a trip spring and they are practically bulletproof. Hiniker has a full board trip with compression springs and I really think all plow manufacturers should look into this, it just makes sense to me.

    Hey, speaking of which...while we're on this subject...Fortydegnorth brings up a good topic of concern...and our most important one...Safety. These springs DO get to the point where they are just wore out and soft...even after they have been tightened up a bit. Care should be taken in the observation and monitoring of the progression of this...Nip it in the bud and adjust them right away..so then you KNOW when they are just plain worn out. The majority of the spring's strength is at the beginning of the pull. After a spring is soft - regardless of the adjustment, it is certainly time for adjustment.

    I have my springs set not so tight and I never have it fold over while plowing unless I hit something.

    OR, he was flat out trying to push too heavy of a load. When mine flops over under a heavy wet snow I just take less of a bite and it works as normal.

    Reminds me of a time a few years ago. Christmas party in a big bar. Guy plowing with a jacked up Blazer. Mold board flat on it's face the whole length of the parking lot every pass! Learn how to adjust your equipment.

    Yeah the springs must not have been tight enough because he had 2 shovels worth of snow infront of the blade and no hardpack to trip it. I am shocked to read that Plowmeister doesn't like the boss. I really thought you liked your setup.
