    Does anyone know how much for a new lift triangle on a MM2?..The new ones dont have the welded ring, it is 2 ears with the pin thru it for a dismount from the chain which wasnt possible with the older style I have...had to unbolt the chain before and feed it thru the chain hole...I was thinking of getting the newer style..

    I had one wear completely thru a few years back- Fisher warrantied it. If yours is worn, they might replace it; its worth a shot.

    It's a "Lift Arm". The part number is 26757-1, they run around $125 & come with the piston pin, & Chain lock ring.

    You may want to change out the two pins (2@ 4289K) that hold it to the head gear at the same time, as well as the U bolts that hold the lift chain (2@ A6148K)

    Does that new style chain holder ever bounce out of position when blade trips?

    Is it possible to just buy that holder piece and have a welder cut and weld that in for a few bux?

    .....well, I suppose you can. It's part 28991. On the new lift arm it is held on by a pin. So, yes you would have to have a welder to attach it.

    By the time you buy the part and pay to have it put on your probably half way to the price of a new lift arm. I sold two brand new lift arms to this guy: plowguy@gwi.net (mike) 207-754-9464, over the summer, he deals in new and used fisher plows & parts here in Maine, so I am pretty sure he still has them. Between you and I...and everyone else here...I sold them and a bunch of other parts for $100.

    As far as your first question...no, it is in there. The hanger is on a pin, so not only is the chain slack when the blade is down, but it also swings in the direction of force or travel.....which ever is greater. No chance of the chain jumping out of position unless you do it with your own two hands.

    I just looked at a pic too...you have to maneuver it out of the chain lock.

    Its a good idea for sure .... Nice fast and easy adjustments.... I put a ziptie around links of chains to label them for use. Sometimes I leave my 1/2" above pavement so I can crouse around without worrying about tripping... NOt for the final cleanup, but when its snowing heavy as hell at midnight in resedintial neighborhoods, and your tracks get covered up fast, why scrape?


    I remember the older plows with the simple clevis hook that would and could fall out when driving on road if the plow bottomed out on a hill....

    Fisher's part number for a chain bag is 8555. If you want to go aftermarket.... it's 5/16" x 108” Not sure of the grade, but I would think 40 is right.

    Def going aftermarket. Not paying $70 for a chain that will cost me at most $40
