Bushhog

I hate to sound like a recording (hehe).I was looking at the gear box and was wondering if maybe 1 bearing is placed from the bottom and the other maybe being placed through the top of the gear box after the input shaft has been removed.I noticed a factory groove to where maybe the race knocks in on the underside portion of the gear box.Maybe that explains why the races and bearings are falling?If that is the case,then when i got the cutter,it came with the wrong bearings?If it is all wrong then now i will have to figure out what belongs in it. Pulling my hair out now.(hehe)

The cutter i have is a Roto-Speed,Model is a Mowhawk.I was using it to cut some tall weeds and all of a sudden it started clacking and banging,so i brought it back to the house and looked and the shaft that holds the blade and skid plate was just hanging down.The way this thing comes apart is first you take the bolt out the center of the shaft which hold the skid plate/blades on and then once that is dropped you take off a retaining plate that 4 bolts hold it on and in which the oil seal is installed and then the shaft itself comes out.Are the bearing races the only thing that holds the output shaft to the gear box itself?Am i being to confusing here?Maybe my cutter is out dated huh?I went back to the parts place that i went to before to get the bearing a few years back and he didn't show anything.I gave him the bearing number with no such luck.But i did manage to find the bearings today at a AUTO parts store but i really don't want to put them in if all they are going to do is fall right back out and mess up the bearing.I got $100 in 2 bearings,2 races and 1 seal.
