You might adjust your clutch pedal so that the clearance between the central thrust bearing and the forward and reverse clutches is equal. If you do that and still have gradability problems, the temperature of the forward clutch after a climb will tell you whether you have clutch slip or belt slip. Has your automatic belt tensioner run out of movement? If so, the belt will be slipping. The belt you have may be the wrong section width or the wrong length, or the belt or pulleys may be worn. The first question is whether something is slipping, the second question is whether it is the belt or the clutch. If the clutch does not warm up, it is not slipping.
If the tyre hits the deck before the stub axle hits the lock stop, the lock stop or stub axle has been altered or damaged. Also, if the right and left lock turning radii are different, either one of the lock stops has been altered or damaged, or the steering gear is running out of movement in the bigger turn radius direction before the lock stop is making contact. If you report what is happening, preferably with pictures, we can talk about how to fix it.
