On my Snapper model #LE1642H, the blades won't completely engage.  After pulling the red knob on the console, the blades try to engage then quickly stop.
Answer -
This could be a problem with the electric clutch, the switch or a safety switch.  First, try sitting on the mower as you would while cutting grass.  With the key on and the engine off, try engaging the electric clutch.  If it engages and stays engaged, the system should be OK and you may have a mechanical issue with the clutch or the blade drive mechanism overloading the clutch while the engine is running.  If it engages and disengages on it's own, the issue may be with the switch.  Not completely familiar with your machine, but an issue with the clutch (electrical) may be causing the switch to trip off (thermal overload).  Let me know what you find and write back.  Hope this helps.

Follow-up: System is OK but how do I check the clutch or the blade drive mechanism for overload?
Answer -
With the drive belt off, you should be able to turn all of the blades by hand (easily).  You would also need to ensure that when the blades are engaged, the blade brakes (if equipped) are disengaged.  Hope this helps.

That fixed the problem, now how can I fix my sluggish Hydro Tranfer?  This Snapper has a Hydrostatic Transmission, it doesn't have the power that it once did and it gets worse when it gets hot!  Can you help?

Answer
If it is not the drive belt to transmission slipping and there is an issue with the hydrostat, changing the fluid and filter (if equipped) might be all that it needs.  If this doesn't correct things, the repair would be more involved and I recommend you take it into a shop to have it looked at.  Hope this helps.
