Robyn, sounds like the belt may have been installed wrong, check your manuals belt routing.

How to adjusted Cutting Deck Belt Tension

You do not say which size cutting deck you have. I will be writing about the 48", 3 blade cutting deck

The belt on this deck is self tensioned. The tension is provided by a spring attached to a moveable pulley on the deck. When the belt is in place you can manually force this pulley forward/backward and it will release the tension.

If the belt is off track, place the belt back around all the pulleys in the correct path, lastly force this spring loaded pulley forward/backward (depending on your deck, the direction is not important, the tension is) to get the belt around the pulley. If the belt is placed correctly, when you release the spring loaded pulley it will properly tension the belt.

Typically, these belts should not be jumping off. If yours is coming off frequently the belt may be worn. When they wear they get quite a bit longer, then the tension pulley cannot apply the correct tension. Rarely does the tension spring have to be replaced.

The other problem that causes belt jumping is worn spindles and stationary pulleys. The spindles are the most likely to need replacement. You can buy excellent replacements for JD spindles on Amazon for very reasonable prices. The following spindles are super replacement spindles for the 48" deck. They may very well be the same for smaller and larger decks; I have not researched that. Just search Amazon for Silver Streak # 285851.

The electrical is part of the PTO clutch assembly. It should only draw 5-7 amps. Ohm reading is somewhere between 1.7 to 2.5 ohms.

These coils do short from anywhere from a partial short to completely.

sounds like the wrong size belt or pulley

check routing of the belt also

Hi, check your belt tension, check all idler pulleys and drive pulleys for free rotation with the belt off and finally check that the belt is not bottoming out in any of the drive pulleys. If so, replace the belt. The blades should come up to speed imediately wether hot or cold and it sounds like your belt is slipping in one or more of the pulleys which drags the motor revs down until it grips. Regards Phil.

Maybe the drive belt is to small and pulling on the assembly, and in turn pulling enough to break the bolt. probably is fine when idle, but under load the condition changes, causing tension to be applied and snapping the bold. That would be the first place I would look.

I have also had other bolts come out of other assemblies and everything ran fine. Until one day when it didnt and belts snapped and so did bolts as and my transmission. It wasnt a good day. So check your belt alignments, mower deck bolts, spring placement, rear end bolts, etc. Good Luck!!
