There is no rating from the manufacturer. You'll figure it out when you start breaking spindles and have wheels get loose on the hubs.

That’s what I’m trying to avoid. Moving approx 1000lbs round bales around on an Allis 400 loader and am thinking about adding a quick change to the loader. I do have the loader mounted towards the back of the tractor, helping to shift the load towards the rear wheels a little. Is the “week point” the front end pivot or the axles? I don’t know if anyone has ever dropped the front, but have seen several axle failures. I always thought that they just were not tightened enough due to poor maintenance, may just have been over loaded I suppose.

If you keep the axle width as narrow as possible, I highly doubt you will ever fail the axle structure itself. The weakest points are spindles and loose wheel bolts. Driving slow and run the tires a little soft help tremendously in reducing shock loads to the axle parts.

I didn’t think about the width so much but believe that is a very good point as I have them moved out a bit now to straddle wind rows. I only mainly use the loader on this tractor, think I’ll move them in over the winter. Thanks for your advice, Kevin

How about putting bigger (wider) tires on the front so it will ride smoother with the bale on?

We've done that on a couple of tractors and it made a big difference.

That helps too, but 30 lbs of air versus 50 lbs helps a ton.

If you're only carrying 1 bale at a time you might want to put a bale spear on the back to
carry the bale to the place you need to use the loader on it.Or if you carry 2 at once always
have one on the back when you put one on the loader that will take weight off the front end too.

I have 9.5l 15’s on the 175 currently, next size is 11’s like I have on the 185, little too tall as this sits up now in the front having 18.4 28’s on the rear, good thought though. Most of the time, I’m pulling a bale wagon as I go unless I have another driver. I try not to dance all over the fields with a bale hanging on the front, though it does happen. It’s always nice to see everyone’s opinion on how to handle chores, never stop learning a little. Thanks all! Kevin

I've had two Customers over the years break a 180 and 185 in half right under the fuel tank from carrying one on front and one on the back. They were more than 1,000 pound bales tho.

I've been doing it with my 180 for years but then again I don't drive very fast over rough ground either which i would think would cause more damage than anything.What would be the difference on having a bale on the back as opposed to having any other type of weight(s)
on the rear of the tractor?

That torque tube is kind of a weak point with heavy weights like described or saddle tanks. I know of two 200 tractors that broke in half in my area years ago. Actually they cracked.
