View Full Version : 36" exmark bucking problem

04-16-2007, 05:26 PM
I have a problem with my exmark metro walk behind m3613ka. The mower
bucks in lower gear and more when the machine starts on an incline. It's
a 2002 machine that is serviced routinely. I had the trans drive belt,
trans drive idler, idler pulley replaced in '05 during it's spring
service. I have tried adjusting the handles and brakes this year with no
luck. Any help is appreciated.

First check your drive axles and coupler splines for wear/slippage, If they are fine then it's most likely worn (Rounded) shift keys and or the mating surface (center of the gears) inside the trans.

Any chance you could dumb it down for me to understand:confused:
I have some mechanical capacity, but I need a little help on the coupler splines.
Would they be in the schematic for the machine

Not sure if you have a peerless or a variable speed, but from your description, it sounds like a peerless (5 speeds plus reverse). It may be that a gear inside the trans that is used in lower gear is broken.

Yes, Look at the parts break-down and everything I mentioned will be listed.
