I'll measure tonight when I get home.
Adding weight to these helps alot. And they are really capable tracors...for their size. You just have to remember their size. I probably use mine as hard or harder than any one. I don't abuse them, but I use them hard.
I have a heavy 54" back grader blade that I have done some hard pushing with. I have also bent the lower three point arms as well. One of my other 1855s also has the lower arms bent in a similar manner. I run up against the rear 3 point lift capacity aLOT. From lifting 55 gallon barrels, to snaking trees, etc. I've had my 1855 buried in soft creek mud up to the rear fender pan. Once I was pulling a sizeable log up a bank and had the cable hooked near the top link of the three point...it jerked the end right out of the 3pt hydraulic cylinder. One problem with weighting the back end, is you'll eventually have to start weighting the front end to keep it on the ground. This quickly becomes hard on the steering gear boxes. To the extreme, you'll snap a front spindle. Over the course of 100 hrs, you lock up the steering gear box.
Again, I don't want to discourage you, because these are truly great machines. But don't expect them to perform like a 30 hp tractor that weights 3,000 lbs. I've never tried a rip shank on mine per se, but at least on my clay ground, I'd have a hard time ripping 12" deep with 1 shank...much less ripping 16" with four shanks. Unless the ground was already practically loose.
A few pictures using mine:
Well, nevermind...the pictures show up, but then when I post, it says I'm not allowed to use that image extension. I guess the ways to post pictures have changed. I'll look at it when I have more time.
