What I did was buy a few used commercial walk behinds, gear driven with blown transmissions..they are cheap and durable.Build a hitch to offset tow it on the left side behind you..adjust your cut heights ...
They tow easy and last forever. .I've found 5 gallons of fuel will last about 8-10 hrs cutting 48" with Kohler CV15. ..I can dig up pics if you want.Dont even try towing something hydro
