Backhoe new 3520 cab/300cx/375 backhoe

   / new 3520 cab/300cx/375 backhoe #32  
I need to add some angle iron to the stabilizer feet to help secure it.
It would drag whole tractor with park brake on and loader on the ground when rolling bucket!

I had the same problem with a 3320/448 hoe I had. It would dig great but you could drag the tractor around easily. One thing that does help is to set the loader bucket cutting edge strait down in the dirt and pick up the front of the tractor with the loader. This will help some but those deere bh's are beasts!!! Almost to much power at times:D. I am really missing that 448 right now.:(

Do you guys have sub frames for your BH's, I have a 48 and it was not standard equip when I got it, now I hear they strongly recommend it for the 48.
Or did they redesign the newer BH's so a sub frame is not required?

If you go to the beginning of this thread you will see pics of how my new hoe mounts. What you see on hoe are the hooks where it hooks to frame of tractor. I'm not sure it is a "subframe" of old in that the only add on to tractor frame are some steel plates (from the limited time I've spent looking) that hook downward so that as the hoe is drawn up it simultaneously sandwiches in the steel sides of the platform then draws two pins on the hoe's frame itself up into the downward pointing hooks on the tractor frame - then the holes at top of hoe frame and bolt on frame on tractor line up so you can insert two big pins at top - it is then secured at 4 points direct to tractor. I think I remember seeing hoes of yesteryear that have "subframe" that nearly runs up under the front axle of tractor. I don't see any evidence of that. I've only spent an hour or two with new ride.... I know, pathetic, I've been wicked busy. I'll post some pics here....

Not that different from mine where the 3pt lifts the hoe and it's pinned to the side plates, not like the older units that stayed attached to the lift arms, mine was sold without any extra undercarriage, don't even know if it was an option at the time (2004) now they recommend/require the extra pcs for my 48.

I guess some machines came in with serious damage like splitting in half in some cases, they say don't lift the rear wheels off the ground with the stabilizers like some including myself tend to do.

Nice rig. I have that same loader/hoe set-up on 3320 e-hydro.
Overall, it's a nice rig, except it smokes blue on cold start-up, LOL. 375 hoe is similar to 447 but fits cab tractors. I've stumped out some pretty large stumps with that hoe. Stumps are pretty demanding and small hoes aren't really built to dispatch them in rapid fashion. The little 375 gets it done with some patience and a good sharp axe or two on hand. Biggest stump I've done was a double trunk hardwood measured 36X24 at the solid wood cross section a foot above ground level. I took this tree down (it was diseased, 10 ft from house in front yard, overhanging roof) limb by limb from above with tractor, stout rope, and chain saw. Left 20 feet standing on both trunks. Hoe dug all around it about 10 ft diameter and 5 feet down close in, cutting all the large roots as required close in with an axe. Filled the hole on one side before yanking it over with the tractor. Took all it had in that tractor to pull that tree over. Down sized the huge remaining stump and root ball with the hoe. Chain sawed the trunks short to the stump. Chained her to the hoe bucket. It was all that hoe/tractor wanted but it finally picked it up with several attempts and hauled it to the woods. Large and difficult project. Small rig did a great job.

HOLY CRAP!! THAT IS HUGE JOB FOR THAT LIL UNIT!!!! (yeah, that's the quote out of context for the day) :D
Dealer said I would be impressed with that hoe - I am. It was a lot of $$$ and could be considered frivolous being I have a 1970's Long 3pt hoe on a '68 4020.....BUT, it seemed to pass the dad test because he said it was very nice unit and was smiling after testing it out (dad's opinion ALWAYS matters - you guys know). I'm hoping this allows me to sell our old unit (minus 4020). Only thing that old hoe is good for is beaver dams where it gets some reach. I have a buddy with BIG TLB to do that if I need it.
