Blows grass trimmings out front left and left side of mower so bad it is hard to mow because of the in your face trimmings

The range of the mover cut should be between 3-3/4" to 1-1/2".

If you are not getting these heights then the mover height mechanism may be jammed or broken. Use lubrication as instructed in the manual.

Left blade is on backwards (liftng edge is contacting grass). Try reversing the blade on the left side.

Nope. If the grass is too high, knock it down to size with a weedeater first. These electric mowers cannot handle the tall, high stuff. If you do, you will surely burn it up.

Dull or bent blades can cause this. Make sure that the grass is not built up under the mowing deck. You can purchase new blades at a Toro dealer like www.arcolawn.com.
tell them Joe from Fixya sent you!

Look under the mower deck. If you can't see well and work on it, you may have to remove the mower deck and flip it over on the ground. Grass and mud buildup in the decj could cause a blade to pinch grass, 'scalping' the lawn. Clean it all out. Dull blades cause cut grass to look torn and brown. Remove and sharpen. Bent blade will cause uneven cut. Replace it. Good luck! Please rate if you found this helpful, thanks!

a lot of problems here.try this.[grass buildup]. usually cause by damp grass or blades not going fast enough to throw into box.engine cutout is then caused by grass jamming blade[s]. backfire is usually too much choke or wrong petrol/air mixture.re bent grass.try cutting driving in reverse[if strip is wide cos of back tyre then blade is uneven.]

check your front tire air pressures

bent part of the blades need to be facing up towards your deck which creates a vacuum and allows a better lift to throw the grass in the bag When bagging blades should be labeled as high lift blades which are designed for bagging . Also which you probably already know its better to bag when the grass is NOT damp.
Hope this helps your issue

Maintaining Riding Mowers Regular maintenance can reduce repairs.

Components of a typical riding lawn mower. (click to enlarge)

It's fun to ride around the yard on the mower, watching scrubby grass (and weeds) turn into trimmed lawn. However, when the grass looks as bad after you mow as it did before, or the mower doesn't want to start, riding mowers aren't as much fun. That's when it's time to put on your Fix-It Club hat and have some more fun.

A riding lawn mower is a gas-powered machine for cutting grass. The engine turns a rotating blade that cuts the top off the grass blades to a specified height. The operator sits atop the mower on a tractor-type seat with speed and height controls nearby. Riding mowers also can be used to pull small utility carts for other yard jobs.

To remove the mower deck:

1. Make sure that the parking brake is locked.
2. Place scrap lumber under the front and rear of the deck.
3. Use the deck lever to lower the deck.
4. Remove attachments from the deck.
5. Remove the blade drive belt from the front pulley.
6. Remove the front and rear deck fasteners, following instructions in your owner's manual.
7. Use the deck lever to raise the deck.
8. Remove the scrap lumber.
9. Remove the deck from under the mower.

To adjust the drive belt:

1. Remove the belt from the large idler pulley.
2. Remove the belt from the adjustable idler pulley.
3. Carefully remove the spring-loaded large idler pulley.
4. Loosen the adjustable idler pulley and move it slightly toward the rear of the mower to tighten it[md]or move it toward the front to loosen it—and retighten the pulley.
5. Replace the belt.
6. Check belt tension and readjust as needed.

I had the same problem and I already found those recommended solutions\ causes on the web:
1. The motor isn't on full throttle.
2. The blade is upside down.
3. The grass is too high when cutting it.
4. Overlap your cuts.

It helped my problem/ I hope it will help yours too!
