Case 446 Rebuild

This is my rebuild of a Case 446. I also show some of my favorite accessories.
Although no larger than a lawn mower this is a garden tractor designed from the ground up to move dirt. Think of it as a forerunner of the sub compact utility tractors.
All hydraulic drive with a wide range of hydraulic and mechanical accessories available from Colt, Case, and Ingersoll. All came with a front hydraulic cylinder and an optional 3 point hitch.

If your carb starts running extremely rich, and your fuel pump and carb are in good shape, check for vacuum leaks. Plugs were wet and smelled like gas, but the carb and fuel pump were good. Found a vacuum leak and after fixing the hose, the plugs aren’t coated in gas or smell like gas.

Will post a video of the factory defect that was the root cause.

I tend to not mess with the settings on a carb unless I've looked at everything else first. Otherwise you may end up chasing your own tail.

Make sure the motor has ball bearings on both sides of the crankshaft as you'll pull power from the front and back.

Dude! You are an inspiration! Thanks for the detailed video , very informative! I'm now inspired to get the vanguard kit and breathe new life into my 446 with 3 point and hydro PTO. Excellent job.

[@t-towncase3808]

It's amazing the difference a good motor makes. Tractor is built so well it'll still be going on the next motor. Thank you!

Glad I found this as I'm getting into the midst of a full resto-mod on my 1976 Case 446. Previous owner did a really nice job of restoring the Onan, but unfortunately in the end filled the hydraulic system with ATF. So I'm just puling it all apart and fixing the missing or maladjusted. Any advice on alternatives to the now overpriced and under-available muffler or hydraulic cooler? I was thinking a plate type cooler from Derale would be more efficient maybe even better with an electric fan?

[@t-towncase3808]

Look for swamp boat mufflers for Onan's, they may fit. Hydraulic cooler has internal fins in the tubes so the fluid is spun to the outside walls for increased cooling, don’t know if these are available from anyone else. You can find used hydraulic coolers on ebay but would flush them thoroughly before use and install the filter and filter bracket from an Ingersoll/Case 3000 or 4000 series to protect the pump.

I have a ingersoll hcs24 that I bought several years ago. Do I need a case tractor with hydraulics to actually use this chipper?

[@t-towncase3808]

Hydraulic powered only. You could modify it or resell it as they're hard to find.

[@t-towncase3808]

Check out the Case 446 restoration videos on the Intakepark channel. Even adapts a Bercomac snow blower to his 446!

Thanks for the overview of this restoration. I want to get a rugged little old workhorse like this, either cub cadet or case.

[@FretsNirvana]

Nice overview thanks! New to these tractors though and I am confused. Does it have one hydraulic motor driving the transmission? Or two, one for each rear wheel. Thanks.

[@cody481]

One hydraulic motor that runs through a differential and has a high low gear.

[@mosheshecklebergstein4900]

Do you have any videos of the box blade?

[@t-towncase3808]

I show it in the accessories video but no videos of it being used.
