Broken Brush HOg -need advice

1. I am assuming tha the loose bolts are the cause of the leaky olk.
2. I cannot find a way to hold the nuts (underside the deck) in place in order to tignten the bolts.
3. I removed the crown nut and tried to take of the 'plate' that holds the blades (in order to get to the nuts). Even with the crown bolt off, I an unable to take off the 'blade plate' (no idea what it is really called).

I was hoping to get it all apart, put some lockwashers on the nuts, sharpen the blades and get it back together in one piece but I am stuck as seen above.

Any ideas?

It appears to me that is is leaking from the bottom of the gearbox. My thought was that there was a gasket between the gear box and the deck holding the oil in and that tightening the bolts would solve it.

The problem with tightening the bolts is that there are nuts under the deck that are moving - and I can't get to them with a tool to hold them in place.

Any more hints would be most helpful. Besides all that, I am not even sure where to take it for repair.

So, how can you determine there are nuts on the bottom of the deck, but you can't get a wrench on them? Generally if you can see or touch them, you can wrench them somehow.

The gear case is self-contained, the oil seal will be a part of the gearcase, not a part of the deck. I would assume that tightening it down will not solve the leaking problem. Generally the leak will be coming out past the shaft.

Popping the stump jumper can be quite a task. I've never done that, but have taken MORE than my share of bearings off of the combines. Tapered style can really, really be on tight, but will fall right off when you get them to move. Regular straight bushings can be a struggle the whole length of the shaft.

On the combine I ran into 1 that was a giant screw - this after pulling, pounding, heating very red, pulling some more.... Another was on so tight (giant cast sheave) that I pulled, pounded, heated (was told not too, but had no options left...) and pounded & pulled & heated, until the shaft split/crushed in half on the end. Never did move, had to find a good used replacement from a salvage combine, drove 60 miles and pulled the whole shaft off that combine, slipped it onto mine by taking the other end sproket off.....

They can be a challenge.

Depending on the age and overall condition of the 'hog, it might be better to get someone to help you torque down the gearbox bolts, fill it full of grease (which won't leak past the seals) and call it good. Removing/repairing/replacing a gearbox on a 'hog is a major PITA, and won't be cheap if you can find someone else willing to tackle it.

As for your bolts, leave the bushhog attached to the tractor and jack up one side. BLOCK IT GOOD!!
I REPEAT BLOCK IT GOOD!!!
You don't want that thing falling on you. Take a look at your gearbox from underneith. I expect you're going to find a wire or something wound around the shaft, thats what's eaten the seal on the gearbox. While you're there check out how big stuff is, thats why I haven't fixed the seal on mine. Someday I'll buy another mower.
Okay, scope out the bolts. I thought that you'd have bolts going into a ring, but it sounds like you might have bolts with nuts. You'll probably need somebody to help. Make sure you use good lockwashers and you might want to put locktite on, depends on if you want to do this again!
