1450 PTO blows fuse
 

After about 45 minutes of mowing using the 44A mowing deck on my 1450 the 10A PTO fuse blows. I've tried both slow-blow and standard fuses. I've adjusted the belt tension correctly, set the PTO air gaps to spec, and checked the wiring. All OK. I find that if I let the tractor sit and cool off and replace the fuse the PTO works fine untill the next time. Anyone had this problem and know the fix? I'm ready to buy stock in Buss Fuse.

what are the two fuses for on the 1450s

On mine, one is for lights, the other for the PTO

I don't know about the fuse, but, the little circuit breakers are great.

No more having to dispose of all that hazardous glass!!


:biggrin2:

10 amps doesn't sound like high enough amps, compared to what my 1861 needs!! :bigthink:

Someone else probably knows the correct size.

its 20-35 amps are the ons i got in my 1250 for mowing and snowblowing.

I *think* that's supposed to be a 15A fuse. 35 would probably make the wiring into a fuse.

I would strongly suggest replacing the fuse with one of the same rating as the manual suggests! ! !

If it's blowing fuses, there's a problem that needs fixing. The fuse is there to keep the malfunction from going up in smoke.

Given how simple the electrical system on a Cub is, it shouldn't take long to troubleshoot the problem. The peanut gallery here can help! :biggrin2:

According to some references found via Google, the manual calls for a 10A fuse. I'd be looking for a mechanical problem causing the PTO to struggle to function....binding, obstruction, rust, etc...

The correct size of fuse for the 1450 is 10 Amps. The PTO under normal operation, only draws 3 Amps. There is NO need to use higher rated fuses than 10 Amps. Further, the wiring harness does NOT support that high of fuse, thus it would be a candidate for a harness fire or burn. Find the problem and fix it.

"Find the problem and fix it".....not very good advice Roland:bash2:

Id really check over your wiring again. Sometimes if theres the slightest break in a wire, and if its touching metal, itl blow a fuse, especially if its only 10 amps. I agree that putting a higher amp fuse in will damage things and lead to fire.

Oh, but it is. Finding the problem, fixing the problem is the correct, safe and proper way to solve the issue as oppose to over amping a circuit with a higher rated fuse.
