Hey guys I posted a thread a little while ago about getting a 420, but I've decided to keep my 318 since I know its a good machine. I think eventually I want to find a 2 stage blower for it, but for now I think if I can get a hydraulic plow I can scrape up the snow that comes off my roof. That compacted snow is a real PITA to clean up and it doesn't do my back any favors either. I found a plow here in Vt, but its made for a 420. Its about the only one I can find in the state. He said it would fit with some one inch shims on each side or by simply narrowing the mounting plate. By looking at some pics of the 420 there is no way that the pins would reach the frame of my tractor if my tractor frame is 2'' narrower than a 420. I'm also not sure by looking at some pics if you can simply cut the plate and weld it back together and still be able to have it fit back on the plow and allow the plow to function properly. He's asking a fair price and he seems very knowledgeable about John Deere tractors, but I'm a little nervous about getting burned with something that wont work on my 318. Its cool to because it has a custom shovel built on it that swivels so you can use it as a plow or shovel. Anyways I thank anyone who can help me with this.

Google 54 blade frame stretcher and you should see some pictures of a frame that mounts to the 318 and mates it to the 420 width so the plow will fit.
It might be easier to get the correct one for the 318. Anything that fits the 140 on up to the 332 will work.
If you get an older one, you will need to change the top hydraulic fitting, or it will run into the front "bumper" of the 318 and either put a nice big dent in it, or break the fitting off, or both.
Any guesses as to how I know this? :laugh:

Just a side note, but if you are planning on getting a two stage for the 318, that means the big 47 thrower. Its a great snowblower, but its really heavy too.
If you can, Id look into a Bercomac before the 47. They are lighter and throw further.
Personally, I run the 49 single stage and have no issues. The 49 I have was purchased by my Grandfather when he bought his 312 in 1976. It has taken care of a couple inches and a couple feet many times over its life, and its not done yet.
Single stage throwers are not as easy to use as a 2 stage blower, but they are lighter and cheaper, especially in this case.
You can likely get a 49 for $500 or less, while the 47 will cost double that if not more.

The 54inch Blade for the 420 should work On a 318 Now a 54inch Blade for a 400 will not:bigthumb:

Superfan 75,

If EricJ's mounting bracket will fit the 318, I believe you would be further ahead with that blade rather than trying to cut and weld the mounting bracket from the 420 to fit the 318.

The 318 (140,300,312,316,330,322,332) frame is 2" narrower at the spring pin mounting location (the main portion of the frame at the front), but same width at the bottom (lower frame horns) as the 420/430.

In other words, he will need to cut 1" off each side to make it work, which is doable, but not as easy as finding the right one.
If its cheap enough, Id try it.

Superfan, I will trade you the mounts on your 420 for the 140 I have if you would like, then you can still have the 54" blade. I just need the mount for a future project.

I use a Blade on my 140 that was used On a 420 By the Previous owner

Doesn't have to do any cutting But finding the Blade side Bracket for the 318 Might be the Problem. if You have that Bracket You Pull 1 pin change out the Bracket

Here is the Bracket that is on the Blade now shown in the left picture circled in red The correct bracket that he needs is shown in the right picture circled In Blue all You Have to do is Pull two cotter Pins and a Rod and switch out the Brackets:bigthumb:

That was an odd 420 then, because the frame is 2" wider on the 400 series.
Something is definitely different somewhere if you are 100% sure that blade was actually used on a 420, mounted correctly (it would have worked with a frame squeezer).

The 300/400 series used to be my "thing", so your post is somewhat confusing in the "what fits what" area, as this discussion was had several times over on weekendfreedommachines when they were the go to place for those tractors.
Your blade, in its current configuration, wouldnt fit over the front of the frame on a 420/430 if there is no gap on the sides (it would be about a 1" gap on each side).
My 318 currently wears a blade from an early 140. No additional brackets were needed.

This is just one thread over on WFM discussing it. It shows what had to be done to go the other direction, blade from a 318 made to fit a 420.
420 and 318 front blade compatibility

They mention Al Zimmerman in there, and hes the one who made/makes the "Frame Squeezer" for specifically for this particular combo work.
Are you sure the guy you got the blade from didnt use a frame squeezer?

Not trying to be argumentative, just trying to prevent someone getting something they thought they could use, but cant.

The value of a 420 plow is about $100 more then a 318 plow. It’s not worth the cost. Flipping the 420 blade if it’s cheap is way better.

No His 420 was from 1988 so the Middle of Production He wouldn't Know what a frame squeezer was even if it bit Him In the Rear end

Ignore the Mounting Brackets. the rest of the Blade Is actually Pretty similar see the Rod and two Cotter Pins shown in the diagram You Pull those 3 Parts The bracket end come off the Blade Frame then you Just Switch out the Bracket for a Bracket from a 300 series Blade

But I think the OP should Just Talk to either of these Places for a Used Blade and Have it shipped a Lot less Hassle then doing what I did

I'll have to check out the frame stretcher, I haven't heard or those. As for the snow blower I do have a model 49 which works good, but I would like to be able to throw the snow further. I have areas big enough that I can't shoot the snow over the bank and then I'm blowing it a second time, and its much harder since its all compacted. I'll have to see if I can find a bercomac.

That might be a good option if I decide to get it. I wanted to make sure it will work with my 318 before I get it. I've been burnt before with something that was supposed to be an easy fit. It sounds like from what I've been reading it may not be to bad. That's why I wanted to see what you guys had to say.

The guy who has the plow used to have a 420 and sold it when he got a compact tractor. Now he's selling his plow and he said it would be an easy job to either cut the frame down or shim it to fit my 318. I just want to make sure. No worries either, I appreciate everyone's advice.

There are a few things you can do to increase the throw distance on the 49.
Tall chute.
Add rubber paddles to the auger in the center, where the steel paddles are. Some guys weld these to build up the edge so there is very little clearance between the edge and the thrower housing.
Smaller drive sprocket. If you go too small, you will increase the stress on the gearbox which is expensive to repair. A modest change yields good results.
Check your engine RPM. You should be at 3450RPM at max throttle. Over time, especially when not checked, your max RPM will change, and generally be much lower. When I first checked mine in 2009 (it was my Grandfathers until he passed, and apparently it wasnt something the dealer checked either), it was about 500 RPM low. That made a HUGE difference.
At one time, I had done all of these, and it certainly did make a big difference.
In deep snow, I could throw almost as far as a local guys 318 with 47 blower. Now, his could have had issues, because I sure thought it should throw further, but Ive seen others that I thought should have too.
The Berco though, that thing blows snow a LOOOONG way!

If you go to google or youtube and search Deere 318 snow and then add Bercomac, youll see all kinds of videos of the 49 (one guy even had the sprocket and paddle mod), 47 and Bercomac.
I always like watching those, as the last few Winters have been mild here, so we havent had much need for blowers. Makes me long for a good, heavy snow a few times a season. I miss using the snow thrower.

Jim I like this simple ideas to improve the snow blower I have. That tall chute isn't easy to find, I've kept my eye open but I haven't seen one for a while. The paddle your talking about building up with weld or adding rubber to must be just the flat part in the middle of the augers ? Then the last question is if the rpm's aren't where their supposed to be how do you bring them up, just adjust the throttle cable ? This is all great. I love learning new things about my 318. I've only had it for about 4 years and its the only tractor I've owned so I still have a lot to learn. Oh yeah where do you find the smaller drive gear ? And yes the gearbox isn't cheap to fix. I had to rebuild after I bought and it was almost $300, but at least I know its all new.

Superfan75,

One of the improvements I made to the 49 thrower was to lengthen the chute. I originally had the short chute, about 20" or so, which might be what you have.

I added a 12" section to mine. I had a local sheet metal shop make a u-shaped piece that had the same profile as the chute. I cut the original chute about 6" above the rotation ring at the bottom and welded the new piece in.

It was fairly simple fix and made a difference.

I've considered trying something like that since I do have the short chute. My snow blower came with some spare parts and I have a spare chute. I was wondering about welding the two together or just adding some steel in the middle.

On the paddles, yes, just on the flat portion at the center of the auger. 2 pieces needed.
I made a couple that used the existing hole in my auger, with flat steel reinforcing plates to hold it all securely. In my case, my housing was/is bent, so it didnt work all that great because I needed clearance for that. One of these days Ill take it all apart and straighten it out again, but until then, I havent put them back on.
On the RPM, yes, throttle cable adjustment.
On the chute, you want a more straight section, so continuing the curve of the original wont help much.
I had a good friend that added about 10" to the end of his short chute and it worked well. His was a bolt together affair. I believe he left the deflector off the top too.
You can also use a tall chute from one of the larger walk behind snowblowers.
Anything thats tall and can be welded to the ring will work.
Ive got one in the garage now that Ive been wanting to get put together for several years, but the lack of snow has kept me from getting it done. Youd think it would be a good time to do it when there isnt any snow, right?
Anyway, its from a Deere walk behind, though it doesnt need to be. I got one with the cable chute adjuster, so I can hopefully use a cable to adjust the deflector at the top when its all done.
