I have an MTD White LC210 self-propelled rear wheel drive mower. Almost every time I release the clutch drive and pull the mower backwards, the wheels lock up. Occasionally as I drag the thing backwards, the wheels unlock and roll freely. What gives?
I have a troy bilt rear self propell that had the same problem. The cure was the belt guides under the belt cover. I replaced the belt and when I put the cover back on, one of the guides was inside the belt instead of outside the belt and caused a slight increase in the tension on the belt. So be careful when putting the belt cover on.
Pull off what looks like hub caps and check the wheel clutches

If i remember correctly, under each drive wheel, there is a small gear, and under each gear there is a small metal rod that is what the transmission uses to propel the mower...it sounds like the rods either have dirt on them or they are just stuck and can not move to allow you to pull it backwards
SOURCE: Wheels do not freely roll backwards
SOUNDS LIKE THE PINONS ARE ON BACKWARDS. THE KEY SHOULD SLIDE OFF THE PINIONS WHEN PULLED BACK AND LOCK WHEN ENGAGED. YOU HAVE THE OPPOSITE PROBLEM OR ITS BACKWARDS!
SOURCE: front wheels lock up when pull mower backwards
Typically self-propelled mowers are propelled using the front wheels, which only turn forward. Pulling the mower back while the front wheels are turning will damage the drive gears. It's best to raise the front wheels slightly off the ground before pulling back.

I'm not sure what else to add, except that it's the rear drive wheels that lock up and won't turn when I drag the mower backwards. This happens on and off whether the engine is running or not. Reading others' problems and solutions provided suggests that there's dirt and greasy grime that I should clean. I'll try that unless someone has a better solution.
Thanks Mike. Easy enough to pull the hub caps and I can do that but I'm not sure what you mean by "wheel clutches." What do they look like? What am I supposed to check about them?
