All Installation Instructions for Husqvarna HU725AWD

Blown Head Gasket

This was an OHV motor so in order to get to the head, you must remove the valve cover and remove the push rods. Remove all four head bolts in an even star pattern. Remove the old gasket and scrape all remaining gasket gunk. Put new gasket on and tighten head back on with an even star pattern. Slide push rods back in and adjust valves to .004 of an inch and put valve cover back on and start it up!

Rear drive wheels bald, no traction

9/16s inch socket, something to prop up one side of the mower (I used a plastic plant pot), and about 5 minutes was all that was needed. Undo the nut on the wheel, remove, replace it with the new one (can't mess it up - just goes on one way which is extremely obvious), replace and tighten the nut -- done. Just that simple. With the new kicks it goes up hill like a champ now (instead of spinning, especially with the grass catcher attached).

Wheels on this old mower were plastic and brittle and over the years broke off in pieces

Can't believe you all had replacement wheels for this dinosaur. They have drive gears attached to wheel. Very simple to fix but broke old exhaust chute on mower when I leaned it on its side. Now I have to find a replacement for it! Geeesh!!!

Front drive wheel locked up, causing the mower to not be able to be pushed.

Removed wheel by pressing off the plastic hub cap exposing the nut holding the wheel. I removed the nut, then pulled the wheel straight off the axel shaft. This exposed the broken dust cover. I they wiggled the dust cover off, cleaned the dirt from inside the wheel, placed the new dust cover, replaced the wheel, nut and hub cap.
