I must be having a brain fart of huge proportions. I have a (should be) stupid simple problem that I cant figure out with this thing.
Its a YT21K46, LT. I got this thing with a rapidly dying single cyl Kohler Courage engine. (imagine that)
I found a decent (for what they are anyway) 17.5HP Intek, just to get this thing moving under its own power once again.... This is a machine that I have known the history of since brand new, my neighbor across the street (RIP) bought it brand new. His wife went to assisted living, daughter moved away and they sold the house. and they were desprate to see this thing gone as they cleaned out the house and garage upon selling the house.... so it wound up at my place.
The engine bolted up like it belonged there. I did have to add a 2nd cable for a seperate choke, but that was the only mod needed (besides a couple of wires swapped around) to the tractor, to fit this engine. Still has original belts. The drive belt is fine, tractor moves and drives under its own power. But the original deck, original belt that used to work fine together, now I can't take out enough slack with the tensioner for it "not to" be floppy loose with the blade engaged. I cannot get enough tension on the belt to spin the blades at all. It seems like the belt (which is original to the tractor, and worked with the old engine in place) seems around 1 to 1-1/2" too long.
I measured the existing belt, I then Googled what the right belt should be/ and the specs that I come up with on the replacement, are actually an inch longer than what I have. I come up with 104-1/2, specs on what should be there is something like 105"-105.7".
Its possible the belt could be worn thin, judging by the "witness marks of rust" on the pulley stack. I know a "too thin" belt will ride deeper in the grooves and make it seem "longer". But not THAT much.
Yes, I took the same original pulley stack from the Courage and put it onto the Intek. so no change there.
the only other idea I had was that I had the deck "hung wrong", meaning possibly that there may have been another set of holes for the deck hanger brackets, but, nope.
I did take the deck off when I first got it, wire wheeled the bottom, painted it with some junk leftover rustoleum just to preserve it and keep it from rotting out, put a set of brand new blades on it, and stood the deck up alongside the shed for the winter/, and I put it back on again in the spring. I could have mis-hung something. I don't see where though/ This is the last thing I need to figure out on this unit, and it can go down the road..... so I wasn't wanting to buy a belt if I didn't have to. and dont wanna "guess" and buy random belts to try....
