I need to pull the disc that holds the blades off the gearbox shaft. The disc is about 18ins. Dia. Which is bigger than any gear puller I have available. Ideas?

Last time I did one the only way to get it off was with a large hammer, some wedges and the heat wrench. I tipped it on its side and leaned it against the side of the barn. Heated the disk with my rosebud and drove the wedges between the disk and the top of the brush hog. Took awhile with multiple heating to get it off. The other way would be to build yourself a VERY stout puller out of heavy flat bar and 1"+ all thread. Have fun.....

Could you drill 2 or 3 holes near the center, thru bolt the puller to the disc?

When I had to remove the drive hub I removed the fine thread nut and lock washer from the drive spline. Then I set about knocking down some 1/2" polar saplings.............hub freed up!

I would drill and tap 2 or 3 holes (depending on what kind of puller you have) near the shaft, where there is some meat. You could also use a large flat plate with long bolts or all thread and use a hydraulic jack. That is the way we did it in industry.

I'm assuming you have a stump pan like in the photos, tapered spline output shaft, this is off a Rhino SE-6. I marked up this photo years ago, trying to illustrate how to pry one of these off. Once you get the cotter pin and castellated nut off, you can use the shaft for leverage with the right size pry bar, but you must be cognizant of the threads so, you may be able to spin that nut back on, the photo is a visual aid, the stump jumper pan is off, but if it was on, the foot of the prybar would be under the edge of the pan, you can wiggle, and pry, unless those splines are seized but good, it's likely to come off.

I just take the blades and center nut off.. I then find a piece of steel that is long/heavy enough to reach across the center of the blade holder. I put holes in the steel cross piece that match the blade hole spacing. I use long/heavy bolts to pull the cross steel up against the gearbox shaft. Tighten the bolts up like a puller. Then hit the center of the cross steel to jar the blade holder. It usually will POP off.

I drilled and tapped mine so I could use my puller.
