    Default JD 3X20 Rear Weight install (pics)

    Here are install pics and discription of adding rear wheel weights on my JD 3520.

    Below pic: Slide the starter weight into position. The three holes in the wheel will line up with the three holes in the starter weight that have the detent for the bolt head.

    Place the bolt thru the starter hole and secure with flat washer, lock washer and nut.

    Tip: I used a heavy blue paper towel to keep from scratching up the wheel with the weight.

    The next step is to bolt the first add on weight to the starter weight. To do this line up the three thru holes on the add weight on with the three threaded holes in the starter weight.

    Now you can theroretically (with in reason) keep adding add on weights as many as you want. Just place the correct bolts through the thru hole in the next weight and into the thread hole in the weight already installed. I went with two because any more than two will stick out past the edge of the wheel and tire.

    Below pic: Shows a lawn and garder tractor weight that I will add to give it a finished look. A friend will fabricate a metal plate that will be sandwitched between add on weight one and two. The little red shims are just to hold the center weight in place for the picture.

    Hope this helps anyone wanting to add rear wheel weights to their tractor. I did experience some difficulty in getting the proper bolts from the dealer to install the weights correctly. If anyone has any questions feel free to ask.

    Hi Dirt,

    Am I wrong or aren't there supposed to be spacers (Deere part# LVU10300) between the first weights and the wheel? Presumably, the spacer allows space to permit the lug nuts to be tightened (or checked) as part of normal maintenance. It appears in the photo that checking the wheel torque will not be possible with the first weight bolted flat against the wheel. Also, the first weight to go on looks like the correct weight, but I thought the second and third weight were the exact same weight (no distinction in deere parts catalog between starter and add-on weights. In fact, my weights are the same (1st, 2nd, 3rd) and stack up fine, holes line up fine, and detent holes are in correct location). I don't recognize the skinnier weights you are using for the second and third weights. Finally, I thought I should mention that using the deere online configurator, it states maximum 2 weights but in the owners manual, it states that a maximum of three weighs per wheel may be used.

    Over all, I guess weight is weight regardless of how they look. How does your tractor perform with the added weight? Do you actually notice any difference? Is it more sluggish to accelerate or stop with the greater rotating mass?

    Super, good point about the spacers. Who really knows what the correct weights are? It seems every dealer comes up with a different configuration. These are the weights my dealer provided. I'll install the spacers so I can have access to the wheel lugs. I have not noticed any difference as far as starting or stopping. I'll report back later when I can try out a side slope that brought the right rear wheel off the ground 5 inches before,as to if there bis now a difference with the added rear weight. Thanks for the heads up on the spacers! Sincerely, Dirt

    The spacers from Deere are quite pricey. I think a similar purpose can be obtained by using 3/4" steel couplers for much less money. Of course Deere calls for 110mm M16 bolts for the initial weight so you can probably calculate the needed spacer width to conform with deere specs. Interesting that your dealer provided you with these smaller weights. They look like they would weight less than the first weight so I suspect you can get more weight back there by replacing them with the larger weights. Even the online video of the deere 3x20 series tractor on the deere website shows the use of only the larger weights.

    As far as trying out the new "stability" of the tractor, I guess I'll let you be the gineau pig and report on the difference. I don't think I have the cahones to retry a side slope that would cause the tires to lift 5" on one side. This would be a real world test of "before and after" results. Often, I read where folks say it feels more stable. However, how can you really tell unless it lifted before and not after......

    Regards,
    Super.

    Hey Dirt;

    Thanks for the pics! Can hardly wait to hear of your "testing" results.

    I don't recall if the R-4 rims on your 3520 are adjustable...? I'm guessing that you've got them set out as wide as possible in addition to the wheel weights. Is that the case?

    Dirt has them set wide. If they were in the narrow position, the wheel center flange would be on the outside and the valve stem would be on the outside. However, the difference between narrow and wide is only about 1.5"

    AKfish and Super, actually I've got an additional 8 inches more in width than the wide setting for the R4 wheels, but thats a whole other story. Unverferth wheel extensions. As far as the real world test. Next time I get my flail mower on the back of the 3520 I'm going to mow the same side slope that caused the right rear to raise off the ground 5 inches.That was the reason for getting the Unverferth extension and now the extra rear weights. I'll also measure the side slope with a smart level to find out just what it really is.

    Super, I was going to check at Tractor Supply to see what they had in the way of spacers that I could use instead of getting them from the dealer. Thanks again for the heads up on the spacers. Thats the great thing about this site is you can have someone check out what you have and make suggestions.

    Sincerely, Dirt
