    I have the same problem with my 15.5 hp Craftsman 42 in

    check to see if all the pulley tension springs are on and in good condition. Don't work under deck unless plug wire is disconnected.

Note: This is about a different mower, but it might be similar enough to yours.  If not, please disregard.  Thanks!

I had a similar issue with our mower, a 2006 Troy-Bilt Pony model 13AN77TG766 (17.5 HP, 42 inch deck): when I pushed the handle down to engage the blades, it took a good ten seconds or so to start the blades turning; even then, they didn't have enough power to cut the grass.  And on any height setting lower than 5, they wouldn't turn at all.

The cause was on page 19 of the manual <URL:http://manuals.mtdproducts.com/mtd/DocGetter?doc=769-02243a.pdf>: Figure 17 shows the "PTO" cable attaching to a hole on the edge of the deck idler bracket, but it was shipped from the factory attached to a hole in the middle of the deck idler bracket, about 3 cm (1 in.) closer to the front end of the machine.  I reattached the cable to the original hole, and the belt is now good and tight; the blades engage as soon as I push the handle down.

Now, today, I'm having problems with the belt popping off the right-hand idler (hopefully just needs the deck stabiliser rod adjusting).

Always remember to remove the spark plug wire before you go near the blades; and watch for hot, sharp, and/or pinching surfaces.

Good luck!

My mower isn't sucking grass into bags. It makes a shrill noise when you engage blades. Help!!


Check you drive belt..sounds like it needs to be replaced. A loose belt will squeal when it slips on the pulley's instead of turning them...which explains the lack of grass being directed into the bags.

Why would a riding mower have the blade turning slow?


If speed varies depending on how much grass you are cutting, look for loose or badly worn belt. If constant slow speed when engine is running at full noise can only be a slipping on pulley or clutch. Most likely clutch. Normally slipping generates much heat so look to your clutch or pulleys. If drive key has separated there will be damage to shaft with metal dust showing.

Husqvarna too slow when mowing


Some self-propelled mowers include a speed control, but sometimes it may seem that no matter how you adjust it, the mower just creeps along at a snail's pace. Most likely this isn't a mechanical malfunction, but an adjustment is probably needed.

Very tall or thick grass can bog down a self-propelled mower, but adjusting the height of the blade may allow it to roll through and cut the grass at normal speeds. If the blade is low, the amount of cutting required may slow down the movement of the entire mower. The frame of the mower may also stick in the high grass. Raise the blade little by little until the mower rolls at the appropriate speed. Going up hills may cause a similar response.

It's possible the drive belt on the mower can slip. Inspect this part to see if it is loose or cracked, and replace the belt to restore power.

When I engage the blades on my ez4824 the blades intermittently stop cutting particularly in higher grass. Do you think this is a loose belt problem? Thanks.


That is the most likely cause of the problem - taller and thicker grass the blades encounter more resitance and the drive belt slips and it doesn't cut. This would likely cause a juddering of the machine when it occurs.

Hope this helps.

We have Toro Lwa 100 Lawn Mower Model #26623. Power engaged, start mowing but lawn mower will not cut grass. You have to stop and let it rev up again to cut more grass.


This 1991-92 model is equipped with a blade brake clutch. When the blade slows down this means the belt is slipping. This slipping can be caused from a few different things.
1 --A loose cable. barterjoe_0.gif
Try adjusting the blade cable on the upper handle. this unit has an adjustable section. make sure the cable is not so tight that you snap it.
2 --A sticky pivot point under the belt cover
The belt cover in the back builds up with dirt and debris. Make sude it is clean under the cover and all of the pivots move freely. ( do this with the engine off)
3 --A sticky belt tensioner under the deck cover
The underside of this machine has a metal cover to protect the belts. Remove it and check that the blade belt idler arm is not frozen in place. this will cause the belt not to enguage all the way.
4 --A worn belt or belt pulley
The large flywheel and pulley can wear. Check this if the belt looks good.
This is all there is to the machine BBC system.
I hope this helps.

Tractor belt slips so blade doesn't cut


There is an electrical clutch that drives the belts. This clutch may be worn. Some will have adjustments that will allow it to tighten them up and not slip. Now when your tractor is running and you turn on your blades there is power sent to this clutch, it is mounted on the engine shaft and has flexible metal plate that is pulled into a pulley buy an electro magnet this plate is worn or could be full of grass/dirt. You need a good strong light, with the tractor OFF, get under and look at this clutch, look for grass/dirt or if the metal has changed colors meaning it has gotten very hot. If it has gotten very hot it is time for a new clutch... Sorry if this is the case. Good hunting.

Airens Zoom 1944 ZTR Blades Slow Down In Bahaia Grass


You mention many PM issues but do not mention a blade sharpening. I don't get on my ZTR without a freshly honed blade installed. "That's" what cuts bahia grass...the blade. You can put all the horsepower you want behind the lade but if you're trying to cut grass with a 2X4 it rips more than cuts grass.
