520H 48 inch plow - Missing part and mount questions

[blue 1]

Hello,

I recently purchased a 520H with a couple of implements. It did come installed with a mower deck, which I recently removed and am now installing the 48" plow.

I'm unable to find the serial number on it. I did have to purchase a few parts(like the rear hitch bracket and the lift linkages).

104659-with-spring-assist-bracket-108485

solid-lift-linkage-7706-snow-dozer-blade-for-down-pressure

105052-short-lift-link-for-wheel-horse

 

I still feel I'm missing a part:

1. Do I need the spring assist bracket as shown in 104659-with-spring-assist-bracket-108485 when mounting the plow at the rear?
2. I feel I'm missing a link or bracket where the lift arm attaches to the plow. Pics attached.
3. Is there anything in front to hold the plow straight and keep it rigid(other than the side to side at the front pivot point)? Three points of attachment seem low for the loads the plow could experience.

Thank you.

Here is what the lift tab on your blade should look like.

 

Here is the manual.

I made up a front stabilizer for mine.

Thank you @cleat, Is there a place I can buy the little tab from?

Likely just need to make one from a piece of flat steel and have it welded on.

Maybe a member has an old plow frame they could cut it off of for you.

• The spring assist is really not necessary with the hydraulic lift.

• Cleat has answered this.

Another front stabilizer .

Thanks for pics!

followup..  would anyone share dimensions of the tab and the hole layout that can be shared.

Also, does it have to be welded on?

 

thanks for the support

@blue  nice pick up on that , while you are right there in  inspection / set up , note the the PLOW STEERING QUADRANT , SQUEEZE PIN  ACTUATION . IS KEY  FOR PLOW SWING EASE . also note the lever rod squeeze lever , compresses the slide pin , that  moves the entire set up . typically set it up on milk crates , and roller stool around it , verifying function , adding  elastic nuts on bolts lets you dial in smooth / easy function , like red aerosol grease , that quadrant slide pin , sound's like a rifle bolt , very easy and solid smooth . like a mineral oil spray down on the blade face , stops rust , and really enhances snow slide off , pete
