I have a Toro recycler lawn mower, with rear-wheel drive. Why does it always look like it is a little bit uneven, when I KNOW that all the wheels are set at the same height? It also has a new blade.

Tighten axle bolt, item 12.

This could be a faulty switch, faulty relay, or fault clutch, or a blown fuse, usually the relay fails before the clutch, but not always

I have a 22" Toro Recycler Lawn Mower with front wheel drive. After many years the original tires wore out, primarily the left front.
After I replaced the wheels the front wheels kept falling off. I learned that Toro uses an unusual two layer washer on the front wheels. You need a) either an exact replacement for this washer OR b) two separate washers. The hole of the washer is 3/8" Everbilt has the smaller flat washer PN 637-009 and the larger washer can be found in the Everbilt PN 281-293. The SMALLER washer must be placed closer to the frame, the larger washer is closer to the wheel. Once this was done it ran perfectly.
Later I found pieces of the original washers in the grass. Toro had the replacement washer available on their website, I was just in a hurry to get the mower back up and running. The Everbilt washers were purchased at Home Depot.

It sounds like your belt is slipping / loose and should be replaced. Hope this helps. Good Luck.

Got the same problem with mine, replaced the drive belt, removed the wheels and checked for rocks and pebbles, greased, checked also bottom of gearbox. grease was present no broken teeth, top pulley has excive side to side play. Have not disaasembled yet. Hope someone would have had a solution here.

The gear drive is probably just a little dirty. You can clean and lube the gears by pulling of the rear wheels and then remove the rear drive gears. Clean them and the axle and reinstall. Be careful to reinstall in the same direction as was removed. A smearing of axle grease in the axle and inside of the drive gears should take care of this.

Also remember that TORO mowers come with a 2 year warranty. Go to www.toro.com to find your nearest servicing dealer.

Good luck!

I'll bet the wheel needs to come off, then get cleaned and lubricated. Either that, or a stick or stone has lodged between the wheel and raising/lowering mechanism. Since the mower is a rear-wheel drive, the traction belt/gears are not the problem.

The transmissions gear is bad need to replace

remove the rear wheels and check the gears in the wheels- they are plastic and part of the circumfrance on the inside of the wheel. If worn replace wheels.
also check belt- it should be tight with very little play when drive is engaged ( obvioulsy check this with engine off).

Problem is in the rear pinion gears on rear axle and the design of the axle itself. I have a 2005 model 20041 had the same problem. I found a Toro dealer that had the fix.The problem is creadted by the fact that there is too much "play" in the rear axle. You have to limit that play by installing shims, or washers First, but the 2 new rear pinion gears for the rear axle. While you're at it, you may as well buy 2 new rear wheels because the "grinding" has worn the sprockets on the reas r wheels.Next, get 2 "fender washers", 1/2" ID and about 1" OD. I found it easier to turn the mower over and set it on saw horses to work on it.( drain the gas and oil first). Remove both rear wheels, pinion gears and all the washers etc. (caution - keep all parts from one side together - do not pile all parts together - keep them seperated by wheel - the reason is I believe there is one more washer/shim on the right side than on the left). Now to put everything back together, find a spot on the axle where the washer will fit in between the standard stuff.Install new pinion gears and replace the rest of the washers/shims just as they came off. INstall new wheels and you'll be good as new!
