I'm trying to find a used snowthrower for a '72 318 tractor. My single stage is beat. JD dealer gave me a price on a 47" with all the extras needed came to $3700!
I've seen some used on line for 1/2 that but they all are 44" ( indicate they all fit many including 318).
Dealer price was for a 47" Quick Hitch. Other requirements included:
-Quick Tatch Hitch - and front 2000-rpm power take off (PTO ) kit
-BM18172 implement drive upstop

THis is all above my pay grade in understanding. I change out the attachments seasonally , change oil and filters and occassional greasing
What does all this mean and are the used packages I see a viable option?

gjdunn,

I had a 47" JD 2 stage (the freezer Chest model) While it will fit the 318, I found the blower ran the tractor rather than the other way around. The Onan had the power, but the blower is a heavsy unit. I had to counterweight the back so heavy that the front end was light when the blower was on the ground.

I suspect your dealer offered you the new style 47". As light as it is, the 318 will likely handle it, but your checkbook not so much. My neighbor had a barco(?) 2 stage on his Troy Bilt, that I thought was a nice lightweight two stage. I think that JD offered a Barco as a JD on the 425/445 tractors. Maybe you cna find a used one that could be adapted. Good luck.

Dave

Gonna have a hard time finding anything for a 1972 318, because they didnt make the 318 until more than 10 years after that, lol.

As has been said, the 2 stage 47 blower is nice, but its big, and its heavy. You need a LOT of extra weight, and that means you wont be able to steer well with it on the ground.
All the minor issues you have running a 49 single stage are multiplied several times over with the 47.

Were I you, Id look into a Bercomac 2 stage. They are light, and they outperform the 47. No idea price wise how they compare though.
Check it out here: Snowthrower - Bercomac - Snowblower - 2 stage
I looked into one once when I thought I wanted a 2 stage for my 318, but the 49 works just fine, and is really hard to wear out if they arent worn out to begin with.
Mine was bought new with a 1977 312, and has been in use since. I did go through the whole thing about 10 years ago and replaced the bearings, chain and repainted the whole thing.


Just for clarification for those who may stumble across this thread down the line, with regard to years of the 318:
If you go here:
Weekend Freedom Machines Forum | Vintage John Deere Tractors - Model Info
You can look up the serial number and find the actual year.
The only way to know for sure is to look up the serial number.
It is important to know the year, as there were two different engines depending on year (Onan B43 and Onan P218), as well as several parts changed through the years, and you will need to know this to find correct replacement parts.

The 317 preceeded the 318, and had quite a few issues (most well known for the Series 1 engine issues), which was the reason the 318 was such a big deal. It was nothing like its predecessor in that it was a complete ground up redesign. The 317 was produced from 1979-1983. Prior to that, the 300/early 316 was produced from 1975-1977. Before that, there was no 300 series. There were other 300 series in those years as well, but the listed ones were "top of the line" so to speak. The 140 was the similar sized/capability machine from the late 60s until the 300 came out.

You can change the chain sprockets to speed up the auger on the 49
True, but too much will put a lot of extra stress on the old, expensive gearbox.
A minor upgrade to maybe a 36 or 34 tooth sprocket, in addition to a tall chute, and rubber paddles in the center of the ribbon, and it should easily keep up with the 47, assuming the engine RPM is correct.
Most guys spend a lot of time and effort trying to get more distance to end up not too happy and later find out they were running 3100 rpm or so instead of Deeres spec of 3450 or Onans 3600.
RPM is the FIRST thing to check and adjust, then start with the upgrades.
