Murray went out of business and was bought out by new outfit. Do not know if new Murray (kept the name) manufacturer will support the older products produced previously. You can always check and cross your fingers.

MURRAY RIDING LAWN MOWER OWNERS MANUAL LAWNMOWERS SNOWBLOWERS

andrew?so you need a manual for 425000x8A this is a 2003 model I found this manual for free at murray.lawnmowerguides.com/murray-lawn-mower-manual.html when you see your model number on your mower it look like this 425000x8 the A tell you the year it was made the 2004 model is 425000x8B BOTH MOWERS LOOKS THE SAME AND THEY HAVE THE SAME FRONT GRILLE.

Unfortunately Murray as we all knew them, and the Murray that manufactured your mower went belly up in the early 2000s. There owners manuals are not available anymore. The brand was purchased by another company and mowers with the murray name are being manufactured again. Parts are available to an extent as well.

There are websites like partstree.com or outdoordistributors.com that allow you to enter your mower's model number and you can bring up an illustrated parts drawing, look at those and it will have the numbers and if you are lucky even the sizes. May be able to find on Murray website also the same drawings.

Note if older than 1993 you may not find drawings anywhere, I have not been able to yet for my 1993 Murray 14.5 Hp 42" riding mower.

Also if the engine is the origingal and it is a Briggs and Statton, to find the manufacture date of the mower look for the model-type-code number on the shroud. Sometimes it is stamped sometimes it is on a plate. The last sequence of numbers is the date code. It starts with the last two numbers of the year, followed by the two digit month, then the two digit for the day and then a few other numbers after it. So if the date code is 010427xxxx then the motor was manufactured in 2001, on April 27th. This is the easiest way to get an approximation of a mowers age, if original engine and it is a Briggs and Stratton.

Locate the tag with your model and serial number on the tractor. Be sure you get the number EXACT or it won't work.
Go to Murray's website and download it. They usually have parts listings at the back of the Owner's Manual

Your owner's manual has a parts breakdown with all parts listed. Find the part # and order from local Sears store. No manual? Try the Murray website (www.Murray.com) and download the manual for model 425001x8D lawn tractor. Good luck!
