Repairs MTD RH125 92 Lawnmower 1994

Hi everyone, I am new to this forum but looking to get some advice please. I jointly own the above yard machine with my father. We have just changed all the belts (awkward job but went OK). My question is that on the right hand side of the machine there is a 'speed' control with 5 notches; it has a picture of a hare at the top and a decreasing symbol/sticker as the notches go down. If this lever goes all the way to the top with the foot clutch depressed, it engages the parking brake. Other than that, I don't know what this lever does as it doesn't seem to be attached to anything really??? When you raise the lever up a notch, what does this do? Am I missing a rod which should be connected to something please? Many thanks in advance.

It is a speed control lever for transmission.

It uses a variable pulley system. The slacker the drive belt the slower you go and the tighter the belt the faster you go.
It wont work unless the engine is running.

Thank you both very much; from what is said above and the very useful manual link provided, the lever certainly should be doing something (which at the moment it isn't). Would anyone be kind enough to post a picture for me of the above / underside of their unit, specifically the speed control lever and the actual mechanism for it adjusting the engine speed please? It is one of those things that once you actually see it, all will become clear! Many thanks.

You need to post your MODEL number, and type, s/n, etc. of the mower (usually found on sticker under the seat) also .... engine numbers and type (usually found on engine ,several locations) see your manual !

also see page 4-20 and further... sorry there are thousands of different mowers from MTD so without the numbers
nobody knows what model you have .
