Sears tractor keeps destroying pulleys

If I hit a root or stick or for whatever season the blade is stopped the belt will keep the pulley spinning and the connection is destroyed. The star opening on the pulley gets every so slightly stripped and enlarged and begins to saw away at the spindle destroying both within seconds. This happens only on the left blade, never on the right. To replace the pulley and spindle costs me about $60 each time. so far in the two years that I have owned time machine this happened 4 times! Can anyone tell me what going wrong ? John Steel is not just steel. Properly heat treating the correct type of steel makes a huge difference in the longevity of a splined connection. Are your replacement parts aftermarket parts? Did Sears change their supplier of parts? Can you swap left from right to troubleshoot this possibility. |
