Sickle bar mower refurbish

So I got these 2 mowers a few weeks ago, my ad on Craigslist really payed off. I got the 2 mowers, The Custom, the ST12, a buncha mule drives and random Sears parts and 3 3 point hitches for $400.

Model # 842.260020
Serial # 86260 and 97522

Neither of them are in working order but both are complete. As you can see in the first 2 pictures, one of them is severely twisted and broken but it's actually in better shape as far as rust goes. So all it's good parts will be switched to the other one.

The shaft and mounting assembly is much better on the twisted one, so it will be switched along with the rest of the pulleys.

Everything is coming apart surprisingly easy. This pulley came off with minimal effort with a pulley puller.

Took the arm off that makes the knives go back and forth off to make sure its crankshaft isn't frozen. It's not.

I assumed the mule drive gearbox's would have oil in them since they have a drain plug, but they don't. The grease? is hardened into a brick. Are they suppose to have gear oil in them?

Thank you very much.
I got one of the mule drive assemblies back together. I'm amazed by the weight of this thing. I'm going to weight each major piece to find the total weight. The mule drive alone weighs 40 pounds!

Anyway, I packed the gearbox with the grease below. I had a whole tub in the grease locker. It's EP Lithium #2.

Lookin good. That grease should work good for you.
Got a new pulley put on and the tensioner assembly back together.

Looking good!

I got my last belt this past week, so I'm getting really excited to get mine going soon!

Where'd you get the belts from? I found all of them at The total before shipping and tax is $24. Much cheaper than TSC..
That's a good deal.

I got one from Erwin Haban, the long belt. One was still on the gear box, it's the medium one from the engine to the mule drive. The short one I got for my birthday from my wife, who ordered it from Amazon. It wasn't the best deal for the belt, but it allowed her to get to $25 for free shipping, so it actually came out cheaper. I will probably end up replacing the medium belt, as it has seen a lot of weather. I'm planning on using it until it dies, then replacing it. I don't think it will last more that one or two mows, but it will get it going!
Belts are on the way. $35.93. Between the 2 mowers I probably have all 3 belts but they're in bad shape. I figured i'd replace them now so i'm not dissapointed when they break.
Good idea starting out with new belts. I did the same thing with the drive belt on the ratrod build. Better off changing it while you have it apart then after you have it back together and trying to use it.
That's for sure. Changing it on the tractor sucks.
I ordered belts mid day yesterday and they came today! The total was only $35 and the belts are the same as the TSC blue belts with a different name. I highly recommend

Went to put the belts on earlier and they're all to short.......... Apparently on the website, when it says 5/8" x 25", 25" is the outside measurement. It's actually 22 on the inside. :banghead3
Yep. I hope they'll let me exchange them..
I am lucky and have a great old school hardware store that stocks a ton of belts and plleys and tractor parts. I took the rat down there on a trailer to match up belts. But now i know what sizes to order online might be cheaper. Hopefully they will exchange for you.
I noticed that the belts looked to be 3" too small. I thought that you'd come upon something that I didn't know about, and was excited to see someone purchase new belts, and use them! Hopefully you get new ones soon, and that you're cutting before too long!
The 3 inch difference is good to know about for when i go find belts for mine.
Hope you get it mowing soon!
I'm sure you guys are thrilled that i'm the guinea pig! :sidelaugh

You got it el simonito, the part number is the actual length. But on the website, the belts are listed by their length. So I ordered a 25" 50" and 59" belts. But that's actually the outside length. The part number is the inside length.

WHY would they even mention the outside length? Outside length does not matter!! :banghead3:banghead3

Gave them a call, explained what happened. They said they'd send out the corrected order today and I can send the other belts back anytime and they'll credit me for them. I have to eat the shipping, but it still comes out cheaper than any other option.

So if you order from them, go by the part # length, not the listed length!
