Electric lift issue

Recommended Posts


I have a 912H with an electric lift that works intermittently. I have had this issue since I bought it earlier this year. Some days it works great, others not at all and then it will suddenly work again like normal. Is it possible it is some sort of cleaning issue, maybe with electric parts cleaner or something along those lines. If so, can someone tell me what to look for? Is there a cheap replacement alternative?

Intermittent electrical issues always scream bad ground to me.  I'm not familiar with the electric lift versions of these tractors, but start checking your grounds at the battery and engine block.  Check the connections at the switch and actuator as well.  You can also bypass the switch to make sure it isn't a failing switch.

Yeah, I plan to take off the deck tomorrow and get under it and see what happens if I jump the switch, it's possible the toggle is going bad but the ground could be the issue as well, good advice!

I read a piece on these one time and it seems they often go bad, the lift unit, which is basically an electric powered ram. What goes bad in them and if they can be repaired, I have no clue.

I have one laying around with a bad motor. It was an intermittent problem for awhile. Don’t know if the problem took out the motor or the motor was the problem.

Problem could be any of the issues mentioned above or some of the "X" wiring on the back of the switch. 

Here's link to UCD's wiring schematic for the electric lift switch (2nd one in post, formatting a little off when post was imported into new software):

Are the motors replaceable?

If you use mfg #1690043, there is a parts manual available for the electric lift.  I doubt if any replacement parts are available from Simplicity, but maybe the manufacturer (Saginaw?).

However if you're interested in a replacement whole lift assembly, Simplicity will sell you one for $1084.15 per Jack's database!

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
