Did all the dc tractors have live pto? Also did they come with one way or two way hydraulics? How about the chain drive rear end it doesn't seem vey heavy duty to me did they give many problems and did you have to adjust the chains very often? Thanks

Only the later tractors had LPTO. They all had 2 way hydraulics but some have the down pressure line plumbed into the hydraulic sump to use it as a single acting system. What doesn't seem very heavy duty about that monster chain drive rear end? My Knight Reel Augie wagon used the same chain to drive the mixer, and that only has one, this tractor has 2! I've never broke one and I use mine on the farm. I've only seen a handful break. Tightening the chains depends on how you use it. Beat it to death with low oil and the chain won't last as long. Treat it right and lubed up and I have original chains from the 30's that are still strong and have adjustment room left!
 
I challenge you to break a chain. I suppose it's possible, but we haven't been able to since 1951. And few tractors have more hours/worked harder than Dad's DC, bought new ftom Hansen Implement in Green Bay.

Live PTO was not available until February 1952, the hydraulics were 2 way. The drive chains gave very little trouble; the ones on my dad's 1949 DC3 have never been adjusted. The only time they might break, and that's extremely rarely, would be in an extremely hard pull such as trying to pull a D9 Cat.
 
We have in our family a 1937 CC that the chains have never been tightened.That CC was used for tractor pulling for about 10 yrs and never broke a chain. They mite need to be tightened now. Also , we have a 1943 SC that we tightened the chains a little for the first time, just last yr .during a complete rebuild of the SC. clint
 
On my 31 c I have had to tighten the chains only once on my watch two times on my dads watch and once or twice in my grandfathers time and truth be told we probably wouldn't have had to but I like to keep about 1/2" slap in the chain and it also gives a guy a chance to check out the rest of the rear end.
 
Been hanging around this Case forum for several years, never saw a post about a broken chain. I've heard the other colors knock them, but only from inexperience, and preconcieved ideas that they are weak. gobble Wonder how DCtom would have reacted to this post.
 
I think my grandfather broke a chain once. If I remember they didn't tighten the slack and it rubbed thin on the bottom of the housing. I think he got really scared because he lost the brakes too. No chain = no brakes. Pulling a couple barge wagons full of corn.
 
The ones that were used a lot would have the chains get loose enough that they could bind up against the case and either break the chain or bust out the bottom or top of the transmission case. If you look at a Case tractor, if the the axles are still slid forward in the slots, the chains have never been adjusted. If they are slid back, they have been adjusted some time. Several of the tractors that I have been into had the chains loose enough to wear a groove in the bottom of the case. If you are restoring or using your tractor, I would recommend that you tighten the chain. It is probably time to change the 60-80 year old gear oil anyway.
 
John Deere built the model D for 30 years and they had chain drive,never heard of one of them breaking a chain either.Ron
 
I have a DH that's had a chain pushed out through the bottom of the case and then rewelded. The answer there is: don't tow them with a broken chain. It happened when my Dad was young.
Every tractor that came off the home farm had had rear end troubles except the chain drive L Case (and they ran that beast HARD). We had a standing order to NOT pull in first gear on the MM 705's... my brother did it once and stripped teeth off the bull gear. (ridiculously heavy Bowdoin clay, eastern Montana)

A few years back, CamboTed was talking about his hopped up D series running about 90 horse (diesel) through the drivelines. They had added a front wheel assist (truck axle) but the rears were using chain and the tractors were holding up from what I remember.

Everything has a breaking point. I tightened the chains on my DI and proceeded to break one the first time I dug the loader into some hard dirt. My guess is I overtightened them a little. I also found out the gear set wasn't quite round. Result: snapped chain. Replaced it, loosened them up a touch and she's happy.
