Tow bar storage question

Bit of a technical / best guess question since I’m new to Jimny ownership and thought I would take advantage of all the expertise on this forum.

I’ve just bought a Jimny to use on our little shoot instead of a gator. It has a tow bar attached with a bolt on hitch (see photos). A bloke nearby is selling one of the cargo carriers off amazon (again, see photos) for not much money.

It’s not compatible with the tow bar I have but I wondered if I cut the carrier arm down and welded on a plate with a couple of drilled holes to attach it to my tow bar the Jimny would cope with it. Amazon claims it has a carrying weight of over 200kg - I’d be using it for feed bags / posts etc to save having to use a trailer all the time on some of the rougher ground.

So, after than rather long intro (!), do you reckon it would work and do you reckon the Jimny would cope or am I completely barking up the wrong tree?!

Yes welding a plate will work
But load capacity will be lots less maybe 50kg would be a safe weight
Or you could modify your tow pack to a 50mm receiver hitch
even then i would say 100kg max load

Thanks both, that’s kind of what I thought. 200kg seemed optimistic but would have been handy as I could get an extra 10 feed sacks on!

Good point re the rails, realistically I’ll probably get all the basic maintenance done over summer then run her for a winter and see what alterations are required after that!
