Going through the manuals in the tech section here I was able to identify it as an earlier E60 version, because the axle support is welded to the box...
.
The Dump Cart is showing it's age, the floor of the box is heavily pitted and has a dozen or more small perforations. I will probably neutralize the rust and then paint the floor inside and out with Por 15 before adding a new layer of steel over top of the original.
.
The tires might be original too, judging by their appearance and the weather cracking. The size seems a little uncommon - (2 Ply, 4.30-8 - almost look like wheelbarrow tires) The axle shaft is also a very beefy 1" diameter - Haven't taken a wheel off yet, - Does anyone know if Case used bushings or bearings in these wheel hubs? Since the trailer was originally rated for 1000 lbs I'd like to fix it up to reliably carry something close to that again. Seems like most yard carts have a 5/8 or 3/4 axle - Browsing the internet last night I didn't find any replacement wheels that used 1" bearings. I didn't have any luck finding tires or wheel assemblies with a 500 lb rating
.
Decided to try hooking up the cart to Maxine (our 222) but realized I had out smarted my self. The 2" receiver hitch was made for moving "real" trailers around the yard and I wasn't feeling like crawling around on my knees fiddling with a pin bracket under the new receiver hitch.
.
The weather gods were smiling today,
it finally stopped raining late this morning. - Time to hit the BigSky shop and fab up a 5" drop hitch for "little" Garden Tractor trailers.
It worked out pretty good for a quick little fab job...

and the travel linkage really binds in both directions coming out of Neutral.
