probably the clutch cylinder is gone :(

You need to hit the cluch before you change gears
1) exsellerate out 2) cluch in (hold) 3) change gear 4) cluch out 5) ecselerate :D
because you have poped the cluch too much and the teeth that your cluch have, have worn out. so it has no grip. you need new gears.
Either gear box is knackerd, or its got the wrong oil in it, if the oil i too thick, it will feel like treacle to change certain gears.
Gears
No its all connected by gears.
They need to have that shape to engage the chian properly
You need to replace your clutch.
Trans. may need a rebuild
when I try to engage gears of mower blades, the engine dies under the load. Read wheels also lock when fowrad and rear gears are engaged.
