Answer: 
Some mowers have a "lock" on the starter that won't let you pull the cord for more than a few inches.. Check starting instructions in your manual. Also be sure your pull cord is not knotted or wrapped around the handle and it goes through the guide loops on the handle.

Answer: 
Looks like you own the same mower as I. Go back to Home Depot with the make and model number of your mower and perhaps they will have a replacement bag there, or they may help you order a new bag. You will need two parts, the catcher frame part # 747-05226 and the bag, part # 764-04077A . You can also go to the Home Depot website. . Some assembly required. Here's to your nice lawn.

You could do one of three things - look in your mowers manual, do an online search or go to a store that sells your make of mower. Most manuals will have a general or specific parts diagram and the part number of the catcher should be there.

Or take this information to a retailer that sells your make of mower and they should be able to look it up for you. I have found the people at Home Depot to be fairly knowledgeable and helpful. In the mean time you can leave your clippings on the lawn. If you don't have a mulcher type mower and the grass clippings are kind of long and unsightly, mow the grass in one direction, then mow it again in another. This will mulch the grass. Mulching is a good thing if it is not to thick.

No, it's a walk behind so you have to push the mower yourself. It is light weight and easy to push, just depends on how easy and level your yard is.

I see you are using a Yard Machine. Does it have gas and is the spark plug wire firmly plugged onto the sparkplug. If you are safety minded, you probably unplugged the spark plug when you were working or cleaning the mower and forgot to plug it back in (as I have done). If after checking these two things, it still doesn't start, unscrew the spark plug to see if it is fouled. If it looks good, put it back in. If it looks wet, wipe it dry with a cloth or paper towel, blow any lint off the tip, and re-install. If it still doesn't start. go to the Troubleshooter section of the manual. You can go to Home Depot with your mowers make and model number and they might have a copy of the manual for you to read or go to the MTD website and lookup the manual for your model.

Answer: 
Bob, try going on-line and doing a search for the manual. Many manufactures and others have manuals on their website for you to either download or print out. When doing your on-line search be sure to include the product full name, and model number (e.g. 21" Murray lawn mower ABC123) to get quicker, accurate results.

The simplest answer is to check the blade disconnect cable and handle for proper operation and check the spark plug for gap or if the casing is cracked and boot to see if it is secure.

Rated 2.8 out of 5 by 109 reviewers.
Rated 1.0 out of 5.0 by Also having problems with engine Only have used about 5 times so far. I put gas in engine and it seem that every other time or so gas just runs out of the carb. I took it to B&S repair, after the gas was completely gone from the engine so my car wouldn't be filled with gas fumes. They had it for a week and then told me they put gas in it, started it, and there was nothing wrong with it. They charged me $25 for simply starting it. April 9, 2013
Rated 1.0 out of 5.0 by DON'T BUY THIS YARD MACHINE Purchased this in April 2014. This is the second Yard Machine I've owned as I had to return the first one the same day due to the same issue - won't start. I have realized that I just handed over $200 to Home Depot and the maker of this miserable product for about 7 mows of my small front and back yard. Home Depot would not take the mower back (return policy) Now I'm faced with the spectre of getting the HD rental department to take a look at it. To do that, I had to preapprove repairs up to $100 plus a $18.95 charge just to look at it. I will not buy any more yard equipment from Home Depot. NEVER. December 27, 2014
Rated 1.0 out of 5.0 by DO NOT BUY This is the worst machine I have eve bought in my life! The filter cover constantly comes off. Gas tank cap is constantly comes off. Oil cap constantly is coming off and blowing oil on the machine before I can stop the mower. and the vibration gives blisters on my hands even with gloves on. The last straw was when the mount for the engine broke. This is the poorest design for a mower I have EVER seen. Also sometimes it just stops for no reason. And even with the proper tourke on the bolt holding the blade on it has come off several times while mowing. This machine has been nothing but a pain to use and has been a very bad experence. July 6, 2013
Rated 1.0 out of 5.0 by The engine is a lemon I bought this and from the very beginning the engine would only run for a few minutes and the die. If I waited awhile, I could start it again, but again it would only run for a few minutes. However, after using it for a while longer now it won't start at all! If you go to the Briggs & Stratton 550ex webpage, you'll see the engine only has a 1.8 out of 5 stars rating. I don't know what they did, but B&S really messed up this engine model. I took the mower to a B&S engine repair shop for warranty service, and hopefully that won't take too long, but this whole process is ridiculous. Stay away from this mower; just go somewhere else and find another brand. July 17, 2012
Rated 1.0 out of 5.0 by A great brand in decline Ever since I purchased my first Yardman lawn mower I refused to buy anything else. They always started. I am very disappointed in this mower. I bought it the Spring of 2012. Like it said, it started right up without a primer bulb. This year however it will not start. My old Yard Machine that I had for many years developed a gas leak so I purchased this one. Decided to check my old one just to see if it would start. I primed it 3 times and it started right up. The company made a big mistake removing the primer button. I feel that is the reason everyone is having a problem starting this once great brand. I am now trying to locate a used Yard Machine WITH a primer button. June 15, 2013
Rated 1.0 out of 5.0 by Ran for literally 2 minutes Carefully followed setup instructions so I wouldn't miss anything, and set it aside before starting to work on something else. My wife started it, mowed into some medium thick grass and it died. She re-started it, hit the grass and it died again. I thought that the grass may have built up underneath, but we looked and it was clean. Tried to start it again (third start) and it would not start, and continued to not start for the next day. pulled the plug and it was fouled, was going to consider replacing the plug but after all the other comments I've read it seems like a waste of time, returning today and going to pay a little more for a better brand, B&S made a lemon on this one. August 11, 2013
Rated 1.0 out of 5.0 by Schizo Mower I bought the 2011 version of this, and from the beginning the engine seemed to have a mind of its own. It will work for 5-6 mowings, although stops a lot and I have to push the choke button to re-start, and then there will be a day when it just won't start. Or better yet it'll run for 5 minutes while I mow 2 strips and then will quit, then can't get it restarted the rest of the day or night. Then 2 days later it'll start and work fine. As I'm typing this, my neighbor is mowing my yard after seeing me once again fighting with it. He said "I've seen that thing act up on you so many times and even spew out smoke, so I figured I'd give you a break." It's time to get a better mower ! July 27, 2013
Rated 5.0 out of 5.0 by Works for me I was very skeptical about buying this mower with all of the bad reviews, but I had no choice. Both hand me down mowers broke, so I was forced to buy what was left. I bought this last Sept. and used it about 3 times. Always started on the first try. I like not having to mess with a primer. After sitting in the shed for 6 months, it took 3 tries to get it started, but now it starts up on the first try. I am able to mow my front and back yard twice before having to fill the tank, so it's a gas saver compared to my older yard machine. May 8, 2014
