Belarus 250AS tractor clutch pedal adjustment 

Clutch pedal should not be floppy if it's flopping like that and your in rough terrain it's possible to pop out of gear happened to me I put an additional spring on the clutch pivot area under the floorboard where pedal bolts to bellcrank keeps synchro interlock shaft from moving if your 250 ever pops out of gear chances are interlock/clutch lever shaft is moving can't be bouncing up and down

It could be argued that what you actually did, was adjust the clutch PEDAL, ... without affecting the clutch ENGAGEMENT.

Tha ks mine won't go into reverse, ill try adjusting it tomorrow.

Nothing like using the proper tools for the job. Normally one turn of the yoke before engaging the throw out bearing will do it (rule of the thumb).
