How do I determine which is the problem? How do I lose the drive key, and how do I replace it? How may have I de-activated the bypass valve and how do I re-activate the valve?
The wheel has a slot in it as does the axel
In the slot is a 3/16" ( or thererabouts ) square and 2" long lump of steel.
Sometimes this stays on the axel, sometimes it stays in the wheel then drops out when you are working on the tyre.
As for the bypass valve, read your owners manual.
If you don't have it download one from the makers web page, they are all there and they are free because of a legal ruling.
How do I determine which is the problem? How do I lose the drive key, and how do I replace it? How may have I de-activated the bypass valve and how do I re-activate the valve? I really appreciate the help.
What model Husq do you have? If you pulled a rear tire, you may have dropped/lost the "key" that fits between the wheel and axle....or, while working on the mower you may have bumped the bypass lever. Here is a IPL of the area in question...
This IPL is for a Yth24v48....on page 8, item #2 is the key, and item #99 is the rod (located on the rear plate between the tires) that operates the bypass.
