416-8 clutch

[scotty 252]

I have a 416-8 and the clutch is really touchy on it i only have a little bit of clutch  before it enagages the belt and i almost always do a wheelie by accident. Is there anything i can do so i have more "clutch"?

[daveoman1966 3,762]

There isn't a 'clutch' per se, but a belt release mechanism that is adjusted by the LEFT side foot pedal.  There is a rod and trunion (#22) attached to that pedal and you adjust it by turning the trunion in or out on the threads of the rod.

I tried that but it didnt help any other ideas?

I have read on here from guys who know more about this than me that you should be using a belt with a fabric covering because the ones without grab to good causing this problem, they recommend using a oem belt

Yeah i put a new oem toro belt on it. Im stumped.

[daveoman1966 3,762]

Replace the belt.... I only use OEM...  They are a few bux more, but will last for years and years.  Besides, many of the after-market belts are not geometrically compatible with Toro / Wheelhorse pulleys..   7473 or 108501 per the schematics.

How about the idler pulley and spring tension setup on the right side...under the belt cover.  Maybe the spring is shot, or the linkage gets stuck somewho.

Beyond that, I don't know.

you might make sure the brake is adjusted properly. If the brake is dragging it will cause the mower to really jump when taking off. Because the mower can't take off slowly if the brake is dragging you will get all the power at once instead of gradually rolling to a start.

I have the same question as the original poster. 1990 416-8, new toro belt, 107939, have adjusted the clutch pedal trunnion as far as possible. the pedal travel is greater, but the belt is so darned tight...and there is no adjustment on the return spring for the tensioner pulley..

any help would be sweet. thank you.

The belt must slip on the engine pulley as it's being engaged which is how it should ease into the tractor movement. If your tractor is instantly taking off then the belt is not slipping on the engine drive pulley as you release the the pedal. Must be a cloth covered belt and the pulley's V surface where the belt rides must be clean and smooth bare metal, no paint or melted rubber from previous belts.  Pull the belt off and inspect that V groove on the engine drive pulley. I clean them with a wire brush and the engine running but just be careful doing that for obvious reasons

thank you, I will try cleaning the engine pulley. this is first time I have ever ran into this problem using the oem parts.
