found a 933 been with same owner for 10 years, asking 6500 for it. I don"t know nothing about a 933 he said was a 68-69 model year. Can someone offer some things to look for on that model? I am wanting this for a farm machine ( cleaning ponds, fence rows etc) I have over 400 acres but not all of it needs cleaning etc. I would love to visit with a owner of one of these or previous operator. Please give me some help on specs etc. I have looked online and cannot find much of nothing.... I didn"t want to post till I looked and just spent 2 hours searching.

thanks in advance

We have one we've used for farm machine for 8 years or so. It was restored by previous owner.
It has been good machine, although we have not done much digging with it. Mostly brush, tree removal and driving sharpened corner posts.
2 weeks ago engine began to overrev and run rough. couldn't shut it down. then it died. Anybody have any thoughts on what went wrong? I'd like to get a repair manual for it too. Anybody know where I can find one?

Hi mocas,

No idea what happened to your tractor but I've been successful finding Cat manuals on ebay. Currently only a 933 parts book available, which you also want if for nothing else than to see how parts go together.

Watch your serial number, often different parts books for different serial numbers.

Good luck. Although..... I'm getting a parts 933 soon (bad tranny). Mine needs a track rail. Seller claims it has a fresh engine rebuild. Haven't yet heard it run, but I don't particularly need the engine. Where are you?

I'm in central missouri. Plan to talk to some mechanics familiar with Cat. Wondered if there is some type of internal linkage that controls the injector from the Govenor. Everything external appears to be in order. We have not had time to look into the problem yet, and want to get some advice before I start. Our machine is in really good shape, always shedded with everthing in working order prior to this breakdown. I'd like to put some type of 4 post ovehead canopy on it to protect from limbs falling, as we use it more for brush removal and fencing than anythng else. Can't says I have ever seen a 4 post canopy on one of these machines, I wonder if they ever had this from the factory? They sure are fun to drive.

You're right. You want a widow-maker canopy. The one on mine was clearly made by a former owner. Welds aren't pretty, but it's kept me alive.

Bought mine to cut a driveway on a very steep slope where I could only work the 80' trees from one side. I used a sheet of stainless on the canopy top. It's got several dents.

Sounds like you're looking in the right direction to solve your problem. I'll try to remember to check my manuals tomorrow.

Hi Scotty,

Like Jim, I've heard that final drive leaks are common with 933. Not my experience with the one I've had for the past 7 yrs. I've found it to be a great machine, well-balanced between power and weight. I've pushed mine to stall, nothing breaks. Not a large tractor, but I've done large work with it.

Recently I was hired by a guy who couldn't find anybody to touch his job. It was cutting in a road up a mountain with large boulders. With no idea what they weighed, I told him I'd try, but no guarantee of success.

The driveway's in. I moved rocks that weighed considerably more than the tractor (downhill only). He, and the other old guys in the neighborhood found great entertainment watching me. Fast it wasn't, running in 1st gear to avoid tractor damage, but the rocks got moved.

Driveway was complete in just over half the time I'd estimated, 1/3 the time he expected. The original driveway I bought it to complete was my own, including removing 80' tall oaks on a very steep slope. It performed admirably. Has made me considerably more money than I paid for it since. For my market, the price you were quoted is good- IF it's a good machine.

Which is to say you shouldn't buy that tractor without somebody perhaps more knowledgeable than you to check it out. I've included an address if you want to email me. My experience includes rebuilding my transmission, a major PITA.

If you buy it, make sure you get an owners' manual. There are grease points you won't find otherwise. The repair manual is equally indispensable if you get into the innards.

Good luck.

A 933 had the same undercarrage as the cat D-2 a lot of the parts were interchangeable,as I seem to remember the weak spot was the final drives.these little machines were pretty good machines,If this won't work for you than step up to a 955H or K. Jim in N M

Hi Buddy,

Wondered if you'd fallen off the edge of the world. I'll give you a buzz when Scotty and I are off the phone.

Scotty, Buddy's a real mechanic.
