I had posted in a few places that my 446 was missing the heat shields / baffles. I found a set of tin work from an earlier style Onan that I can make work - Thanks Ross!
A bit about me... recently retired, Heavy Equipment Mechanic trying to stay out of mischief and keep my self occupied - Last year I purchased an '84 446 package deal - tractor with sleeve hitch, mower deck, rototiller, single bottom plow, cultivator, snow/dirt blade and snowcaster... I also added a 48" boxblade from Princess Auto. The intended end use for all of this fun stuff is 10 acres of hardwood bush. We purchased land in the Lanark Highlands near Ottawa 18 months ago with the intention of selling our house in the city and moving to the "woods" to really enjoy retirement. It seemed to take forever, but we finally got plans and permits approved and hopefully construction of a house and garage will start this spring as soon as the snow is gone and the frost is out of the ground (last spring it was early May).
My other tractor project is an antique '65 Case 530CK loader backhoe that is temperamental as all heck and leaks from every orifice of its old creaky body...
I'll be working on it as time allows and using it for work on the property (foundations / Septic system and other fun projects) Of course I do like working on all kinds of stuff and have a couple of Suzuki 4x4's (Samurai's and older) from the '80s that are slowly rusting away but refuse to die mechanically...
And tools... yeah, I have a few...
or a few too many depending on if you talk to my wife first 
Looking forward to getting inspiration from other peoples projects and sharing stories of my adventures (On the appropriate boards of course)
Cheers !

and I made our move to rural digs 10 years ago . Best thing ever done . As you know you machine is all most 40 years old . There are some things that you will want to address so it is a reliable fun machine to use . You said you have been on other sites and have picked up the missing tins for the motor . If you could list what you are already planning to do we can fill in the blanks on what else you should look into . 
Adventure/ misadventures in tractors is always welcome .
Welcome to CCIGT Gerry, glad to have you here. 
Hope you enjoy your time here and join in. Your 446 will be a handy little tractor for your new homestead. A friendly warning, they tend to multiply.

let's go, it's finally time to blow.
