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.

I don't know about the fuse, but, the little circuit breakers are great.
No more having to dispose of all that hazardous glass!!  10 amps doesn't sound like high enough amps, compared to what my 1861 needs!!  Someone else probably knows the correct size.

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! 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
 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.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.
MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
