I have a White Outdoor series 650 21" cut and the drive belt keeps breaking. It is in Indonesia. The original lasted only a few months and I have not been able to get original ones, so I have been replacing the belt with automotive belts (size is 11A0800), and they don't last.
I guess that the problem is overheating of the belt when the "clutch" is pulled in to stop it. But maybe it is something else.
Any suggestions?
Full description is White Outdoor series 650 21" cut, side discharge rear bag, bought July 06. 173cc engine.

If it's a briggs engine, sounds like you have water / debris in your carb fuel bowl. Using spray carb cleaner will only work if you remove the bowl and clean the carb jets. Also, you could have water in the gas tank as well. First, remove your air filter, then remove the 3 screws that attach your filter bracket to your carburator and mower. Take off your fuel line at the carb and drain all your gas into a clear jar. If it looks very yellow, cloudy, or see water in the bottom of the jug, change your gas. Using a half inch socket wrench, after gas line is disconnected, remove the fuel bowl and clean with carb cleaner. Also, examine the bolt you just removed. There are 2 jets in the side and one at the end. Using the carb cleaner, make sure they are clean as well. Use the carb cleaner extension tube to spray up inside the bottom center of the carb, where the bolt threads, to clean that area as well. After all this make sure ur float assembly is intact and reassemblt the bowl to the carb and reattach the the fuel line. finish bt reattaching the air filter support bracket makinf sure the gasket between the carb and the bracket isn't damaged.

The rule of thumb for the routing of the mower belts is to make sure the "V" inside of belt is fitted into your pulleys. The "FLAT SIDE" outside of the belts rides with the flat side up against your idlers (lookes kinda like a pulley but is wider.) It might take you a couple of attempts to get it right. When the belt is on properly it will be nice and snug.
Good luck

Herbert, no there is no way to adjust the tension. The driven axle is held in position by a spring that keeps the tension on, and when you pull the clutch it rocks the axle and driven pulley back a little to release the tension on the belt.

Herbert, I mean that when the drive to the wheels is stopped, the belt just slips on the pulley. From memory, you have to pull the wide handle to get enough tension on the belt for it to drive the wheels. I am in Australia and the mower is in Bali, so I am going from memory.
Daryl
mrfixit-jerr, thanks. No doubt you are right. A friend of mine will be in Bali in a week or so and he'll get a mechanic to look at the drive unit. No doubt I'll need parts and that'll be another drama, as the MTD site doesn't even mention that model number.
I'll try to let you know how we went.

Herbert2000. Ihave just been back to Bali, and got the chance to have another go at the mower. I had the story wrong, but your comments sent me in the right direction. Of course the drive doesn't get transmitted the way that I had indicated, and the belt isn't intended to slip as a clutch. the problem seems to be that the belt was 5/8 of an inch too short and consequently the pulleys didn't line up properly. The new belt seems to have sorted the problem. It has only been used a few times now, but I am full of confidence. So we got there in the end.

Thanks very much from Australia and Indonesia (technical help in outback Bali is a bit thin on theh ground)

I was afraid of that. One thing to check: V-belts can have a few different angles for the "V" side, check to se if the replacement belts you are getting match up to the pulleys on the mower.
A question: You said something about "...overheating of the belt when the "clutch" is pulled in to stop it." What is being stopped?
Is there a way to adjust how tight the belt is?
