ok so im curious as to what the breakeage or slippage point of a electric clutch is on a lawnmower, i have stalled a mower several times with the deck engaged when i hit something so i know itll hold well enough to stall a engine but i want to know how much force would it take to actually cause the clutch to slip or break

Google is your friend. Go here and look around. Per that Warner Electric site, some can take up to 250 lbs ft torque. A 40hp Kohler Command Pro can only produce 63 lbs ft torque. I've never seen one that was adjusted properly slip.

Kinda depends on the voltage of your battery at the time of the slip...

In many setups the clutch is driven off the engine by belts. I bet in most situations, the belts would slip before the clutch.

I've never seen an electric clutch slip... seen the belts slip and even break, but not the clutch.

someone mentioned to me of a ideal using a elctric clutch in a pulling machine. they said something about making the belt at a fixed tension and using the electric clutch for starting and stopping, it sounds like it would work im just woundering how much force itll take to cause the clutch to break or slip if its even possible, he ideal of it sounds plausable, i cant see any reason for it not to work.

I saw one that was run on a small dune buggy style kart, guy had a 20+hp Vanguard V-twin with no governor, he ran dual V belts down to a pulley on the axel...he would wind it up and then engage the PTO and it was like a clutch drop in a car...he broke alot of belts, sheared alot of axels and keys but the old clutch never complained...

I was sketipical about electric clutches until I tested (RED) that has a 18.5 Hp B/S opposed Vert. 44" deck Sharp Blades. Can usually mow the yard in 6th Hi gear. When I went to the back yard, over the septic the grass was 2X taller and 3X thicker. Raised the deck 2 notches, Shifted to 3rd and still killed the engine, no belt or clutch slippage. I am real impressed with the magnetic clutches.

Ever try and forse open a Door that has a magnetic lock?

Same here.

Like Kevin says, you need ~12VDC for the clutch to stay engaged, but I've never experienced issues that way either. For me they were like a switch. Either on or off, no in-between.

RED-85-Z51 thats great to here that lets me have confidence in that it will hold, the electric clutches sound tougher than i thought they would be, i knew theyd have to be tough to withstand mowing condidtion but wow that tells me there really tuff
