I got the chipper on the back of the tractor this past week. Chipped up a few branches and limbs. .. think it may be due for a sharpening.. anyone done these blades before ? ..I'm not concerned about removing them and bringing them to a professional sharpener ..but is there a trick to re installing them ?

Wallenstein knives can be flipped, have you done that? If not, there is a whole unused second sharp edge waiting there. I haven't flipped my knives yet (been 8 years) but when I do, I plan to buy a second set of knives for backup so that I can rotate the sets and have one to use when the other gets sent out for sharpening.
No trick to removing and reinstalling them, but check the owner's manual for some tips. There is a trick to setting the depth of cut, which is shown in the owner's manual. There is a ledger, a flat plate that the knives "slice" against. You adjust the position of that to control how much wood is sliced off each time a knife passes the wood. That setting is very important. It should be checked from time to time.

I will take a look at it and see if the blades have been flipped yet. I bought it used and did not get the owners manual. .. Im just concerned about installing them wrong if I take them out.

YES. If you chip only one type of wood, ie Christmas Tree debris, and determine the optimum gap, keen edge can last a long time.
If you chip miscellaneous, ie hardwood branches, softwood, vines, hard dry wood, juicy green wood etc., the gap is inevitably a compromise and the keen edge dulls sooner. Chip debris before too dry. Bone dry material heats the thin blade edge much more than moderately dry debris, accelerating deterioration.
I eventually took Wallenstein blades to a local machine shop for sharpening. Was about $40 for four really, really sharp but strong edges.
After three years I decided chipping was not good use of my time relative to the volume of material which needed disposal. Sold the Wallenstein and began burning.

I've had my BX62S for seven years. I've not sharpened nor flipped the blades yet. No need - I only chip green pines. Be VERY careful. My seven year old blades are still razor sharp on the cutting side. Op Manual covers the models listed on the cover.

On my Bearcat chipper I'm always careful to clean both the blade and flywheel where they mate up as there is often dust and a kind of varnish like material on them. I chip everything from oak to brush and fruit tree trimmings. I have a 1" wide belt sander mounted on the work bench that will put a razors edge on them, you just need to be careful to not over heat them especially near the ends.
I believe its the the BX42

What grit of sandpaper do you use?
