Hey Some ones got big problems haven`t they !!
Yes it can be done not very easy you will need to use maybe a stille saw with a pulley fixed to it or a strong motor with a pulley
Then you can take off the belt & use it to drive the pump with the motor Etc.
Not very easy job to do but it can be done !!
The hard part is keeping the belt tight and on at the same time
You get the idea once you try
If you are going to tow with a rope then remember you only have a small amount of breaks that is if the front sphere is fully charged
(not recomended to use a rope!! use A Frame safer all round)
Let us know how you get on
