Small Engines (Lawn Mowers, etc.): Snapper Riding Mower Clutchline, snapper riding mower, riding lawnmower

Question
First off, thanks for your help.  I recently purchased a snapper 10.5 HP "convertible" riding lawnmower with a combo clutch/brake pedal.  The mower shifts (poorly, but capable of changing gears) when I first start it, but during use loses driving power when mowing very tall grass.  Once it stops/stalls I can only get it to go in reverse.  The gear shifter has been somewhat difficult, even when working ok.  Do I just need to replace the clutch cable?  Can I tighten it somehow?  I am a novice with small engine/mower mechanics.  thanks

Answer
Hello Tim:

To Answer this Question, I Require the Model Number Off the Mower, Please. Snapper has Several Different Ground Drive Systems. On Some you can Adjust the Brake/Clutch Cable with Spacers on the Cable at the Brake/Clutch Pedal. To Tighten the Cable, Simply Move a Spacer so it is Behind the Pedal Instead of in Front of the Pedal. Thanks.
