News: 10/5/12 - All new members are REQUIRED to fill out the signature section of your profile. Otherwise, you may be deleted from the forum. This is to help me determine if you are a member or if you are a spammer. Thank you.

9/22/12 - I ask that you please add a signature line to your profiles on the Cletrac Forum to help me to determine who is spam and who is not. You don't need to drop everything and do this immediately, but please do it when you get a minute and you are visiting the forum. Just go to http://cletrac.org/forum2010/index.php?action=profile and put something in the signature area. If you no longer want to be a member on the Cletrac Forum, please remove your membership.

8/10/11 - Added a new board: Trucking and Hauling

5/30/11 - Just added several new pictures to the Photo Gallery, including several Alfta Track OC-4 working in snow logging, several from the Chicago Road Show, and some from a logging show (not all Oliver/Cletrac). All these pictures are from around 1963 and were scanned from old slides given to me by my late friend John W. Davis. Go to the Photo Gallery and click on "NEW" to see these pictures. Quality is marginal, but I think you will enjoy them.

2/13/11 - Just added a new board "New members introduce yourselves here".

Folks, I just added a new photo gallery where you can upload your own pictures with descriptions, etc. Right now this is in the beta testing stage to see how it works out. Give it a try, but please keep a backup copy of your pictures just in case we decide to use something else. I would prefer you use your real name on the photo gallery, but if you really don't want to, please use the same username as on the forum. Please put your images into the proper categories and take care when your write out your descriptions and image names so people can search for them. I am learning this as we go. At least at the beginning, I have it set up where the administrator has to approve members. I am afraid we may get porn spam in here if we leave it open. To get to the photo gallery, use this link: http://cletrac.org/photos/

Folks, when you join the forum, or when you get the chance to update your Profile, please be sure to put your location and interests. Filling out your signature would help as well. I've been getting some spammers joining and posting links to sites that are completely unrelated to Cletrac or Oliver, or anything to do with tractors. It would make it easier for me, as well as all the other members, if you guys would put your location and interest in your profile. See http://cletrac.org/forum2010/index.php?topic=1299.msg5184#msg5184

Thanks,

I have a DGH and a Friend had an OC 4 loader which I have operated.  The main problem with both machines is the lack of a foot brake peddle.  You need 4 hands to stop on a hill to shift and operate the loader or dozer.  You folks with other models, do any of them have a foot brake? Comments!

It's one of the short commings of a Cletrac that was trying to be overcome in the later years when Oliver would not put much money into the crawlers. My OC-12 has a foot brake, but it is about worthless - they wear out very fast if used. I believe the OC-96 had a foot brake pedal along with the steering pedals. Not sure about the late OC-4.

Blake, on your OC 12 does the foor pedel operate a separate brake or does it operate the two steering brakes together?  You are right it is one of Cletrac's few short comings!

It operates a separate brake - a dry brake that I believe is on the impute shaft to the transmission. Way undersized and wears out quickly.

If the brake is on the input shaft it should be relatively easy to get at and change.    That kind of setup is used on a lot of trucks, maybe a larger brake from a truck could a adapted to fit for longer service.

From what I recall, it's just a little pad of brake lining. I don't think there's enough room in there for much more.

I was working with my AG-6 on a hillside this past weekend, and sure could have used a footbrake!  
Between the throttle, 2 hand brakes, and the gearshift, it certainly was a challenge.

Zen, is what it's all about.
If the brakes are good, then the levers give all the stopping power you need.
I have not really pined for a foot brake, but I think it would be neat to
have a Hrydualic control on the right foot peddle or maybe an accelerator.
If the govenor is working properly then an accelerator is not really needed.
I have found than I am steering the tractor single armed many times.
The other arm is shifting and ajusting the dozer blade or trottle if needed.
When everything is running right then the "Zen" of the situation cancels out any stort coming
that may or may not be there.
Keep Welll,

George,

A de-accelorator is the way to go. Then you can step on the de-accelorator and shift, then let off an the engine's running it's normal speed again.

I think our AD loader has one. And I recall the OC-96 had one too.

Blake, A de-accelorator sounds like a useful
device to run the tractor faster and with more fuild of motion of the operator and the machine.
Admittedly my experience of crawlers is limited to the HG and OC-3's.
I have thought of maybe getting a different model of machine, but I would need to sell off something else.
I am not ready to part with what I have now.
So, I'll wait, I like what I have I guess.
Keep well all,
GG:cool:
