So guys, I straightened the arm and the pin on the tractor. Put the belt back on. No spring on yet. Cotter pin just set in pin to hold arm on. When I pull up on the arm, like the spring does, the forward end of the arm is about 3” off the ground. So is this correct ? 81” belt is installed. If I put a longer belt on, that would raise that arm at the front, but will it make the belt roll of the drive pulley because of entering the pulley below top centre ? If I put a shorter belt on, that will make the front of the bar closer to the ground. Don’t want that ! So do you think the engine pulley, stationary v pulley and idler pulleys are the correct size. Who knows what has been done and what parts have been changed in 40 years.
And I believe that when you lift the thrower, this tightens the belt, which causes the idler pulley to come up, which puts the front of the arm down, closer to the ground.
The more I think about this and explain things, the more I think what happened to the 446 is, with the arm only about 3” or so from the ground, and with the thrower lifted, which lowered the arm more, while was driving I came down a slight hill which then turn to flat ground, and I would say the bar caught the flat ground long before the rear wheels got to the flat ground to level the tractor.
So, how do I raise that bar so it’s higher up ? Why is the bar so long out the front, to begin with ? And could I just cut some of it off ?
Ideas and your thoughts please.
Sorry for the long winded post.

Who did the custom work on it? The pictures are hard to see all of it. But, that extension for the spring is wrong which means the spring was wrong. The handle should have had no way to do what it did. So, you need to go look at another snow caster or the parts diagram to customize the caster.
Those blue belts only last about 1 hour on Case tractors. Too much twisting and torque. OEM belts, 10 years for most people.

So took the 4.5” flat idler pulley off and put a 3” on. That lifted the arm up to a reasonable level. Not as close to ground now. Tested it in snow and it worked good. Good power. Snow caster throws reasonable. Traction is my trouble now. Need better chains.

Don't you have weight on the rear of the tractor?

75 lb wheel weights. And chains. But chains fall in bars on tires. Slip on ice. Tires are 6 ply and hard. No flex. I’ll have to do some thinking Eugen.

With lugs you need 2 link chains or stud the lugs . . You have enough weight on there . I personally run turfs with chain winter and lugs in the summer .

Yep, I should get a extra set of wheels and put my turf tires on them. The original turf tires are only two ply and have lots of flex. Then put a set of two link chains on, plus the weights, for winter. And just run the ags in the three other seasons. But the ags look sooo good. Hehe. Hard to find wheels here. Looked when I got the ag tires. So I could switch them if I wanted. Any thing I buy has to be used, cause can hardly afford anything new, and even used is pricey and very hard to find.
I’ll rig up something.

I’ve allways heard that chains were no good with ag tire because they fall in between the lugs. This is the first time I have experienced that. I never thought I would ever say, I should be using turf tires and chains. Ive argued over the forms for years defending putting chains on ag tires. I have other garden tractors with ags and chains and never had a problem. So there ya go. I was not completely right. Hehe.
Any way, I’ll see what I can do with out spending much money.

My 446 with 200+ lbs on the back and ag tires with no chains had good traction. Can you add some chain to create cross links over the lugs? And definitely more weight. If you have a sleeve hitch it's not that hard to add weight. My 446 came with a vertical rod on which the previous owner put old brake rotors and weight lifting disks.

It would be easy to say "just get a set of turfs, load and chain them, and swap them out for winter", but I know that they probably aren't easy to find by you.
The farm tractor chains we use to have had H- pattern crosslinks.

I hope to add chain some how Eugen, I’ll add some thing on them. No sleeve hitch. The rod is a good idea. On the 224 I used a couple of rotors.
