Howard CD6 Speed Reducer

Postby Guitars415 » Sun Dec 06, 2020 10:09 am

Hello. First post here. My grandpa passed away a few weeks back and I inherited his 1949 cub. The tractor is great. Engine was rebuild in the 80's I think and runs super strong with zero smoke. Everything works on it. One thing I found out is it has a Howard CD6 Speed Reducer and I'm trying to find more info on it. I'd like to read the user manual and was wondering if anyone had a manual on this? I haven't engaged it yet. I'm going to leak it soak in some lube before I try moving the handle but I'm sure it works just fine. My grandpa took very good care of this tractor. Fired right up after sitting for 7 years. Thank you for your time.

Welcome to the Forum. After your second post, you have access to the PDF Manuals here. Click on "Quick Links" upper left of the page. In the drop down menu click on "PDF Manuals", then on "OEM Implement and Attachment Manuals", then on "Howard Rotavator", than on "Howard Speed Reduction". There are a few on the Forum that have those and may be able to answer questions that the manual doesn't cover.

If it sat for 7 years, you should prime the oil pump, otherwise you’ll have smoke followed by some really nasty noises.

It fired up and there was no smoke or any nasty sounds. I have videos posted to the Facebook group. Engine is very healthy.

Do you have good oil pressure?

Yes. Oil pressure was perfect. It's a rebuilt engine.

The reason they mention about priming the oil pump is that it can lose its prime over long periods of time. And no oil is definitely a problem. Sounds like a great tractor! Hope you can hand it down one day!

Thanks. I'm starting the restoration process this coming summer.

The speed reducer has a plane3tary gear arrangement in it that when engaged (lever toward the seat) reduces the speed on that axle and the differential compensates with the other axle and gets quite a workout. There are warnings in the manual to only use it to decrease speed, not too increase pull.
If you are not part of the solution,
you are part of the problem!!!
