Has anyone out there had any trouble using the Bobtach feature on a loader? I took the bucket off of my new ct440 and when I went to put it back on (1st time) the pins wouldn't drop down no matter what I did. I took it back to the dealer & he voiced concerns of an apparent new welding technique designed to tighten up the connection - apparently too tight! I'll keep you posted.

I have a New Holland skid steer like the one in my avatar to the left. Though the principle is the same--two locking pins drop down under force and are spring-loaded, the way the mounting plates are designed and made vary widely. At least with mine, I have to keep the pins lubed up or they will stay up (I have a hydraulically operated quick attach opposed to the manual lever type) so there's a lot of power to push and pull them and they still stick. My locking pins have a large roll pin pressed into each pin that rides in a slot. The slot keeps the locking pins from rotating. When they stick I remove the bucket and dowse the locking pin area and the roll pins with diesel, motor oil, or whatever is handy. Then I tap on the lock pins' roll pins and free them up. ....

earthwrks, That would be a nice feature to have but undoubtedly spendy on a CUT. The dealer told me he had one other similar problem, on a skid steer, and it turned out to be the bucket. This one is well lubed but thanks for the tip. I'm sure I'll use down the road. ....

It was spendy on the SSL too--close to $900 :) but worth every penny ---saves time and my back---especially when it's really hot or cold (I have an enclosed cab :) )

I would look at whether your mounting plate is out of whack---that wuill keept the pins from engaging. Even my skid steer's mounting plate gets bent--that is one side is further out that the other due to really wracking it. But it's easy to fix--just place a 4x4 between it and the the opposite side and draw it back until they're straight. What also causes it is getting a rock or dirt build up between the plate and the loader arm without a bucket on which really increases the rigidity. ....

I got the ct440 back today and the service tech said some welds needed to be cleaned up. I haven't taken the bucket off (still recovering from yesterday's workout) but not too sure it looks like the pins are completely seated still. I haven't done any loader work with it yet to bend or plug anything up. Those previous posters weren't kidding when they talked about these tractors needing a break-in before getting up to speed or power. This is the first non JD I've owned but am CAUTIOUSLY optimistic. It's a nice little tractor but I have a habit of comparing it to my former 4720; not a fair comparison. I looked at the 3520 but they're not very beefy, plus the cab on this one "fit" me better. ....

You can buy a product called "anti-seize" from most part stores. It is rather pricey and smears a long ways if you get it say clothes or seat. It might solve you issue or help solve your sticking pins. I have sliding lift arms on on of my tractors, the lift arms are not in the dirt and doubt very much dirt gets thrown over them, but some how enough to jam them gets in there. ....

The anti-sieze I know of is thick and goopy--gotta think it would attract dirt.

Kenny do they make uncle-sieze too? Or gran' pa-sieze? ....

A few years ago Deere had "Ride and Drive" type day where dealers could bring customers to get a feel of their newest machines. I don't think Deere builds them any more but at that time they were building the big four wheel drive/four wheel steer one armed big loader thing that had several different buckets. I drove it around and the reps wanted you to change buckets from the cab. Hey that was neat, flip a switch and either electric or hydraulic pressure pulled the pins you backed away drove up to another bucket, flipped the switch pins went in. I wondered afterward how well that would work in the real world with dirt, cow manure and whatever all over things.
I see lots of Gehl machines around for roofing etc., but haven't saw a Deere for quite a while. ....

You're talking about a telehandler. They were used to do hurricane cleanup on the coast---they could stay on the roadway and reach across the big wide ditches and grapple trees. Tires don't hold up well on pavement though. ....

EW;
"Telehandler",yes, I couldn't remember what they called them.
I don't think Deere wanted them use in consrruction where people worked from the platforms on them. That may be why they don't sell them anymore. ....

Generally they're not used for lifting people, though there are baskets that can be used. They probably realized that the market was saturated with many other makers with long track records that were more desirable. Funny, I do have an aerial work platform that'll go 40 feet--and I use to lift oak beams like a crane when I rebuild old barns. OSHA can't say anything when I use it because it's being used by someone in the same category as a farmer. Feels kind of funny when it gets up on two wheels lifting! ....
