The stabilizer cylinders on my 447 backhoe are weeping a little bit of hydraulic fluid from around the cylinder rods. I probably lose a couple of tablespoons a day, but the leaks are there. It appeared soon after a dig that slid the tractor forward (from the hoe seat point of view) a foot or so. It is just about impossible to dig up a stump without rocking the boat so to speak. I am being too aggressive with the backhoe? Or is the weep normal?

I don't think you are to aggressive, and the weeping is NOT normal. There could possibly be scratches or scars on the pistons that have torn the seals, or you just plain need new seals. Rebuilding the cylinders is a fairly easy and inexpensive job if you want to do it yourself.

Anyone ever use Baum Hydraulics for cylinder repair kits (or anything)? The John Deere kit for the 447 stabilizer cost $53.56, Baum has it for $9.63. The kit number is AM36221.

I use Baum for quite a bit of stuff. Never had a problem with anything from them. Heck, shipping for you may be more than the seal kit. If you are doing both of your cylinders, which you should, order an extra kit just in case you tear a seal when installing it.
