scag 48 walk behind belt drive jumping out of gear

I pick this mower up a few months ago, really cheap from a friend who go out the biz, 48 scag wb belt drive with a two wheel velkie, mostly just use it for a few properties steep or hilly, but started noticing 1 and 2 gear it will jump or stop for no reason just for a second, kinda stop and go, 3,4 and 5 still worked fine, until today only 3rd is working now, checked the belt tight and traction belts are good, is the tranny bad, found some on ebay pretty cheap. just wanted a second opinion. before I but a new tranny. thanks

Cut a 1 ft length of fuel line and slit and tie wrap it under the gear lever. That will put some drag on the lever.

Most likely causes of what you describe is either ...
Probably one or both of those Retaining rings on the outer axle shafts came off or slipped or broke, allowing the shaft to ride OUT towards the plate, this causes the splined coupling to skip splines...

Part number 51 on this page:
http://www.partstree.com/parts/?lc=s...29&dn=09010023
Keeping in mind without model and serial number that is most likely NOT your mower, however the parts are similar enough and may even cross, you will want to get out the model and serial number and look up YOUR mower before ordering thou.

These retaining rings are not expensive, and well worth checking into.

It's also possible one or both the jackshaft bearing is shot (part number 50).

Another possibility is the bearing in the idler pulley is shot (the small pulley that tensions the transmission belt), replacing the pulley would fix this.

Or that big pulley right underneath the transmission is wobbly.
