I acquired an STX38 1998 I believe. Yellow Deck-

I am trying to understand what the clutch pedal does. I looked at the microfiche, and looked at the tractor and all I C is a bar running over to the brake, it rotates slightly when the clutch pedal is depressed, then there is a spring in a spring providing tension, but I do not C how it is disengaging anything to allow for shifting.

When I shift (clutch depressed I get a bit of a jerk)

Couldn't find the answer in search, sorry if a newbie question-

any info is appreciated! :fing32:

on the hydrostatic stx the pedal is nothing more than a parking brake.On the gear drive it actually is a brake to stop moving.

getting closer... I think.

Should have mentioned, I have a manual shift model-

So it is not actually any type of clutch, in that it lets something slip so I can change gears?


With a manual transmission is it acccepeptable to change speeds on the fly then?

again thanks, new to this-

I believe it just disengages the belt from the pulley for a second to shift.

my fault.I misread the post and thought you were asking about the brake.The other guys are right,it loosens tension on the belt so you can shift.

On gear drives its tough to "shift on the fly" like a car. You come close to a complete stop in between gears. The main reason my 185 took over mowing duties from the 180 is the speed change flexibility of the hydro trans.
