With all these links you can have a comprehensive "low tech" way of
building donkey and oxen carts and harnesses. Very easy,and you can
literally start your own business and be in demand! I would download all
these pdf's and assemble a library now-while the links are still
accessible..you never know when you might not be able to find the
info.......
One of my particular favorites is:

TR29 Low Cost Steel Framed Cart for Two Donkeys (1999) 9pp PDF 100kb
PDF link-http://www.eng.warwick.ac.uk/DTU/pubs/tr/animals/tr29.pdf

In this booklet we tell you how to make a simple cart from square steel
tube and timber. This Technical Release does not tell you here how to make
the axle - you will have to read another Technical Release to for this. We
have designs for stub axles with PVC bearings and with needle roller
bearings that you can make yourself and we have designs for twin offset
axles using PVC, wood and scrap ball bearings. All axles can be made
without machine tools - in fact you do not even need a drill!
two men can probably make one cart in a day.We've designed these carts to
be easy and quick to make.
These carts have been tested in Nigeria, Kenya and Uganda and we have had
only a few serious failures caused by poor welding or incorrect material.

The main internal publications of the DTU are Working Papers, Technical
Releases and Research Notes. Most DTU publications are available here for
download in a number of formats and hard copies of Working Papers are
available free on request to the DTU. Technical Releases will also be sent
free on request but only to addressees in developing countries.

* Technical Notes contain descriptions of designs/techniques for use by
manufacturers, extension agents and users of equipment, written in fairly
simple English to make them more accessible to technicians speaking other
languages.

* Working Papers are used for descriptions of research findings and are
written for a "professional" audience: comments are welcome. In some cases
revised versions are subsequently published in outside journals.

* Research Notes are smaller outputs from our research,progress reports
of research undertaken by the DTU but as yet incomplete, case study
material, and exceptional undergraduate research reports. Often these notes
form the basis of fuller Working Paper

Working Papers

WP42 Low-Cost Rural Transport in Sierra Leone,
C.E. Oram & T.H. Thomas (1994), 15pp

This short paper reviews the demand for rural transport services and
discusses the present inadequacy of such provision in Sierra Leone. It
examines the main transport modes that might meet its transport needs and
concludes that both animal power and assisted human powered transport have
the potential for a significant contribution. The focus of the paper is on
the provision of vehicles rather than on the provision of roads and paths,
and various interventions are suggested relating to the use and manufacture
of such vehicles. In this context manufacturer training, marketing and
vehicle design, are discussed. It is concluded that small town
manufacturers and artisans are the most appropriate sources of vehicles for
rural transport and that their needs for profit and return on labour must
be met if there is to be any hope of sustainable development.

Covers work carried out by HS Pearson and colleagues in northern
Nigeria in 1993 and 1994. The paper is divided into two parts: part A
(sections 1 to 4) discusses animal carts in general, the design options
available for their various components, the particular circumstances
affecting the development of the DTU Borno oxcart, and its main design
features; part B is a set of full manufacturing instructions for the basic
cart and some minor variations of it.
