Hydrostatic drive is weak

There are two separate belts underneath. The upper belt goes to the hydrostatic transmission. The lower belt goes to the cutting deck. Please be sure about the belt being fine. Unless the belt is new, the belt could be stretched. The pulleys and tensioning devices will need to be inspected for wear, damage and function.

there should be two drive belts. they should be replaced both at the same time. if one is wore so is the other one. use the correct belt, from a lawn mower parts store.

I would check the drive belt going to rear end if not that I would check fluid level in transmission.

for not charging pull the cover off the top of the engine look for damaged wires mice love to eat them going slow i would check the belt for oil or see if its tight

Hi, it sounds like the hydrostatic drive is getting too hot. Remove the battery and battery cradle and clean all grass and debris from around the hydrostatic drive and cooling fins. Also check the fan wheel on the hydro is not damaged. Regards Phil.

first sign of a failing hydrostatic transmission

You didn't indicate what model so I don't know if it is hydrostatic drive or not. If it is not hydrostatic drive, it is most likely a worn belt or clutch adjustment. If you don't have your manual you can download one here:http://www.mtdlawnmowerparts.com/manuals.php
If it is hydrostatic drive it stil could be the drive belt or low water in hydrostatic transmission, or even water in the oil in the hydrostatic transmission. Always list model number when asking questions.

Sounds like a loose belt check the tension spring if they ok check and see if belt is strectched

Try using the heel of your shoe and pulling back on the brake/clutch pedal and see if it helps. Cronic problem with these mowers-Belt slipping when linkage get a little wear-with no solution???

I hope this will help you...under the side panels on each side of the mower, there are "reverse lockout safety switches", they are supposed to stop the blades when both handles are pulled back. If one or both of the switches are out, the deck will not engage. Also, under the right side panel (when sitting on seat) there should be 3 relay switches, the one closest to the motor controls the PTO., if this is out, the PTO will not engage.
