    Has anyone ever replaced the trip edge on a Western MVP? On the parts list, they call it the "Base Angle". It's not the cutting edge, but the part that the cutting edge bolts to.

    My concern is the 3 trip springs are putting down pressure on the base angle (aren't they?) and I'm not sure how to remove them without getting injured. Can I just unbolt the trip springs at the bottom? OR, do I need to get the pressure off of them first? If so, how?

    I do believe that they are like a coil on a car. Need a special tool or you may lose a limb. Western mechanics guide says they make on for it. PN20043. Wouldn't recommend trying it without it.

    When I ordered the Base Angle (online) I also purchased the tool you are referring to. I tried it and the problem is that I'm trying to recoil 3 springs with one tool...way too much pressure and the tool looks like it's about to fail.

    So, I'm wondering if I can loosen the bolt at the bottom of the trip spring and just remove the base angle? Or, is it still under pressure? If so, I think it may be minimal, but I hate to take the chance.

    OK - I've got it figured it out and it's relatively easy. For those of you that may need to do this repair, here's how I did it.

    Forget the stinkin' spring tool...you just pull up to an outside corner curb, lift your blade a little (it's best to have the wing centered on the corner) and move forward. This will activate the trip edge...all you need to do then is insert one 1/8" bolt about 1/2" long into the each trip spring and your set.

    Just back up and the spring tension is removed and you saved $35.00 on the tool (well, I didn't).
