110-4 slow cutter deck speed

[TomBoy 0]

Hello,

I have a 1991 110-4 rear engined WheelHorse. Not the most elegant WheelHorse but it has cut my lawn pretty well up till now.

It has been very dependable but had started to run a little rough so I ordered a new airfilter and set about cleaning it up and sharpening things.

There had been some belt slipping going on and the deck belt looked thin and worn so I ordered a new after market v-belt for the deck A48.

Parts replaced and reassembled the engine is running really well but...

The deck is running really slow...so it just strokes the lawn rather than cutting it. Now the obvious culprit would be the new belt but I am not sure it is that.

Could the PTO belt be the cause? it is the one that takes all the strain every time the pto brake is applied.

Does anyone know the original spec of a 114567 belt? Just thinking my aftermarket may be a poor fit.

I also noticed that I don't appear to has a 'extension spring' on my deck, part number 112228. It appear to hold the angle of the tensioner to prevent the v-belt from rubbing. Can someone confirm that that is what it does? It appears to be impossible to obtain the part in through Toro UK so I might have to order it state side.

Many thanks

Tom

114567 belt is an HA x 47.91 inches. That is 1/2" x 47.91".

Fractional horse power belt A48 is 1/2" x 48". These are for light duty electric motor applications as a rule.
Industrial belt A48 is 1/2" x 50".
The 48" and 50" are circumference lengths.
Gates makes a 6927BR belt for this application.

See this deck uses a torsional spring 108177 to tension the belt and it is still available from Toro. Make sure the pivot is not seized. I see the 112228 extension spring but don't know what it is for.

Gary,

Thanks for the detailed response, looks like the belt isn't up to the job.

Would something like this work?

The tensioner is free and working, the 108177 spring looks and feels fine. Even still it looks like the belt is meant to be loose and the tensioner just positions the belt to make greater contact with the pulley.

I have ordered a 112228 spring, just for the hell of it, I am pretty sure its only purpose is to hold the tensioner at an angle to prevent the belt from hitting the top edge of the tensioner assembly. The cable tie temp fix appears to do doing the job just fine but I will let you know when I have correct spring in place.
