SMS425

Just picked up this SMS425 sickle mower. Looks like it may have to do a complete rebuild, not planning on painting it, just mechanical. Looks like a few parts may be missing, but overall I think I can bring it back to life. When I figure out what's missing will put an add in the classifieds.

Looks like your missing the slide shoe that goes on the bottom of your gear box housing.

I got some time to tear apart the wobble box, sorry I didn't take picks of the mess. Oil was like grease, there were more brass shavings and pieces than I could have imagined, one of them was completely gone. Thanks to @dclarke for the notes on where to get all the parts and @Lane Ranger for the shoe and the tips of the sickle. It is starting to take some shape. I worked on the wobble box tonight, had to remake the pin that holds the yoke to the weldment shaft. After I damaged one of the bushings I took a look in my parts drawers and found a few NOS bushings for a sickle mower :woohoo:  I was able to replace the one that I damaged.

I had to do some similar work on the  wobble box too Tom!   Somewhere on Red Square there are some pics of my 50 inch Sickle Bar Mower rebuild.   I used some bearings on the outside of the box that were not original and I think they will work.   I am going to  run the sickle this spring.      I had to have a machine shop make my pin for the  U shaped yoke that rides in the eccentric wobble part.    That  weldment shaft is probably what takes the most beating of the parts in the box!   It is a pretty neat piece of work with parts and bearings and oil seals all going in a less than ten inch square cast box !   Looks like it is coming along great!

Looks like that lathe was a good investment, Tom. I really enjoyed rebuilding the sickle I had, one of the neatest attachments Wheel Horse sold. Good luck with yours and keep the pics coming.

Tonight I mounted the SMS425 to my 855. Seems a little noisy, I think in need to make a new pin to connect the wobble box to the sickle knives. Hoping to go and try it out tomorrow.
