Ok there is three sprockets one on the transmission a guide in the middle and onle on your back axle. take a wrench and loosen up the middle sprocket. slide it all the way back untill the chain is snug or tight. tighten up your bolt and it should notice it drives faster and thats how you keep it from falling off. hope it works for you

All chains have a master link installed that links the 2 ends of the chain together. See this link:

-Find this link in your chain.
-Then remove the clip and slide the link out of the chain on one side.
-Re-route the chain over the sprockets.
-Connect the two ends of the chain together by sliding the master link through the end of the chain.
-Install the plate and clip on the master link.
-Tighten / adjust the chain so that there is about 3/8 inch vertical travel in the chain mid span

If there is no adjuster for the chian and the sprockets are some what worn, you may have to remove a link from the chain by driving out one "chain link" by removing one pin and barrel with a mini punch and installing a "Half Link"

This should help you install your chain. Just note that if the sprocket teeth are quite pointed that is a
sign of long term use of a lack of lubrication. A chain lubricant is usually a very heavy grade oil 90 or 130 wt gear oil. You can use WD40 to losen the chain but I would recommend keeping the chain lubricated at all times to prevent unnesessary sprocket and chain wear.

Thanks for using FixYa.

Mower stuck in highest gear.

Did you check the cable running from the throttle to the engine? could be stuck in high revs. Mine had a a similar fault, the cable got stuck and the spring bend. also check if the gearbox is hydrolic or manual with a chain. The older types have a chain that can snap or get loose after a while . The chain is held down by 2 disks, release one of the disks (count the turns ) a little bit so you can put slack onto the chain, re-tighten the chain by pulling the disks from each other and fasten the bolts , with the chain back under tension, the gears should run normal again. If its hydrolic then consult a dealer as that's messy to do yourself. i love the old school ones, no hydrolic just pullies and chains :)

I removed the chain brake cover and did not release the brake. is there a way to get the cover back on after the fact?

Hi, carefully put the cover in a vice with the vice jaws tightened up where the bar nuts normally go.Then pull the chain brake lever backwards towards where the handle bar would be. It will require a bit of pressure but it should click back. Then refit the cover.Hope this helps, regards Phil.

My chain keeps falling of, when i put it back on and tightened the chain tension it brakes the chain. What do i need to do?

The chain shouldn't break from tightening the tensioner. Is this a bad chain? Tension should be tight enough that the chain has about 1/2 inch of back and forth movement in the middle of the longest run.
Let me know if this helps or if you need more information.

Toro riding mower/chain adjustment

There is an adjustment for the chain. There is a sproket that you can loosen and adjust. You should be able to get it from the outside of the machine. Should be a 1/2in or 9/16in nut.
