Have a Zero Turn mower (50 inch deck), engine will only run with choke full on and bogs down or stalls when demand put on engine ie. mowing in high grass. Changed filters (fuel and air) with no change in performance. Any helpful ideas appreciated.

sounds like the coil is breaking down at high temperature. make sure the engine is not covered with grass clipping and dirt. replace the coil. i think this will solve your problem

The likely cause of this is that the grass is too high for your mowers deck. You should try just mowing about 1/3 of the blade at a time (if you can) until you reach your desired length, so if you grass is 6" high, only take off about 2" at first to reduce the stress on your mower. Set your mower deck to it's highest setting and give it a shot.

Also, be sure that the blades are sharp, and if you don't have mulching blades, you should get some! Grass this high will leave long clippings on the lawn which can suffocate the grass, mulching blades will chop up the clippings into smaller pieces, which is beneficial for your lawn!

Finally, make sure you aren't mowing wet grass. If you mow when the grass is wet the clippings can stick together and clump up under the mowing deck which will cause excess strain to the mower and maybe even cause it to shut off.

If none of this works, you may want to use a string trimmer to remove the first two inches of your grass and then continue mowing as normal!

Hope this helps! Happy Mowing!

Something is jammed in the drive and when you put the mower in gear the motor stalls. U need to locate the source of the problem - once you do that all will be copacetic.

Your mower doesn't have enough power to handle very thick grass at high speed. You need to go slower across the lawn. That's easy to do if this is a push mower (just don't walk so fast) or if it's a self-propelled model with a speed control. But if it's a single-speed model you'll have to mow the lawn in fits and starts: squeeze the lever to move it forward; release it when you hear it bogging down; wait for the motor to reach full speed; squeeze the lever to move it forward again; repeat. Also, is the grass very high? If so, try setting the cutting height higher on the first pass, then lower it for a second pass. Finally, make sure the blade is sharp.

When you say 'going forwaed', is that while mowing or does it do it without the blades engaged or 'not mowing'?

dirty air filter on carb or spark plug might me loose lowering compression which will in turn rob your power

Check that the blade brake is disengaging. Slip belt off blade spindles and check that they spin freely. Check underside of deck for clogged grass, ropes, wire, etc.

I do know that they are set to run really lean. try pulling your choke out a bit.

what is happening is there is tomuch grass in deck & not discharging as fast as it cuts it if deck is ajustable put it on high setting then try if it works then got back over it with a lower setting this is most likely the case to much grass in deck while mowing blade gets cought up alot with alot of grass in deck

i have a cub cadet 2130 2000 seris but it quits when i rekwase the brake pedal
