Rick:
3500lbs doesn't sound like enough to me to haul it. I have a 2305 which is 1450lbs (according to the manual) operating weight, add maybe 300lbs for the loading in the rear tires, 360+160 for the FEL + bucket, 700lbs for the
ballast (I have 560+lbs concrete in a steel ballast box) and I'm up to 2970lbs. If I put the 200lb mower deck on I'm over 3000lbs. I also regularly want to carry attachments. I don't know how much the 4010 weighs but it's got to be more than a 2305 and even a single axle trailer has got to be close to 800-1000lbs.
I ended up buying an 18' Peaquea 10,000lb gvw (Trailer weighs 2000lbs). It wasn't much more than the 16' 8000lb. Tandem. Tandem will give you two axles with brakes also. I did see some single axles rated up to 7000lbs but they weren't much less so I opted to get the bigger trailer. (Just in case I end up getting a bigger tractor - Maybe a 5225.. /forums/images/graemlins/wink.gif - Actually the 5225 wouldnt' fit widthwise - Heck, maybe a 4520 naw, /forums/images/graemlins/wink.gif.. I also did have the luxury of plenty of tow capacity so I figured I'd get the heavier trailer. I'm pulling it with a 2500HD Sierra with an 8.1 and a six speed stone grinder std.
Originally I thought I could haul it in my enclosed snowmobile trailer which had maybe 4,000lbs of capacity(6000gvw) left but after figuring how I'd have to re-inforce the ramp, floor, etc. I decided to go with a flatbed.
As a side note, I actually was worried when I started adding up weights since after all that if I actually put 500lbs in the loader I think I could exceed the combined axle capacity of the 2305 but you need to discount the weight that's not supported by the axle bearings (Tires, wheels, loading in wheels, internal axle shaft, diff cage, etc. Anything that's supported by the wheels and not by the axle bearings comes off that. ) Then I felt better.....
