Anyone every build a subframe mount for a backhoe for their TO-20?

I am in the process of building a subframe mount currently and would appreciate any advice. I am planning to mount it to the rear axle mounts and the loader subframe. I could also tie it to the center of the rearend using the 4 holes for the drawbar mount but I do not think that this is a good idea although I have seen it done before with a forklift.

I am mounting a light duty foreign made hoe designed for 3-point. I will not use the 3-point mount since I know that it is not stable and that the weight distribution is too far back from the rear axle.

The tractor already has a Wagner loader so I will have good balance and I will probably put 14.9x28 on the rear.

Ed, Terry,

Thanks for the very good ideas. since both of you connect to the top of the differential without problems this seems to be an OK mounting location.

I built a frame to attach a Kubota backhoe to my TO-20. It has four pins that hold it on and I can mount it in about 10 minutes. The pto hydraulic pump sildes into a trailer receiver built into the frame under the tractor. I will try to post some pictures.

This is the frame that bolts under the fender mounts and the differential.

I built new stabilizers.

This is a drawing of the frame that goes between the tractor and the backhoe.

Terry,

Nice clean job. But are you worried at all about the stress on the top link mount? You system seems easier to deal with than ones that have long arms that extend toward the front of the tractor. Do you have a CAD drawing of the parts? What is the plate for near the hitch receiver? I like the idea of mounting the pump to the hitch receiver it sound very secure. Looks like you are using a Prince pupm like I am.

Thanks

It is not mounted on the top link mount but on the long pin below the top link mount. The one that has three ears with a long swivel pin through them. It don't push or pull on the draft control spring. Having said that, that is the part that I consider the weakest link of it all. I worry about tearing a big chunk out of the differential housing. I try not to abuse it but you know how that goes. The square plate above the hitch receiver bolts to the swinging drawbar mount under the rear end. That hitch receiver is handy for a lot of attachments. I have 3 different size trailer balls, and I have a pto shield that slides in there to keep weeds and vines from wrapping around the pto shaft on my bush hog. That is a Prince hydraulic pump. It is mounted on a piece of square tubing and the splines of the pump mate with the pto shaft when the tubing is slid into the receiver. I do have CAD drawings and a lot more pictures from different angles if you can use them.

Terry,

I can use any information that you are willing to share. It will save me a lot of work. I have both AutoCAD and SolidWorks so I can read any type of CAD file. If you have it details of the pump mount would be very good to have. After the connection to the differential, I consider safe mounting of the pump critical. A torque arm and chain from Prince is just so-so.

Many thanks.

Hi!, I reworked a 54 sherman hoe to quick disconnect off of a to35. On or off in 20 min. with no tools, just 3 pins. I to wanted it in close. I've been running it for 5 years and it's holding up and is very strong but simple. I've seen my son digging out stumps picking the whole tractor off the ground with all the weight on the stands. I welded the tongue for the hitch under the pto to the hoe. Made a solid top link on the hoe . And made too pipes that come off the hoe and hook in the long pin that runs across the rearend below the top link on the tractor. The pump is on the tractor so i added long hoses to run the hoe off the tractor to get it in place to hook up. I will take pic's and post them tomorrow if you are interested , It may give you some idea's. It is to late tonight. hope this helps-ed

Ed,

Thanks for the quick reply. Please post the pic's especially of the linkages between the hoe and the tractor. Did the Sherman originally have the rear facing stabilizers or did you rework them too? It seems that rear facing stabilizers make more sense when mounted to a tractor than do side facing ones. All of the pulling force is most commonly along the length of the tractor not side to side.

Mark
