I am thinking of purchasing a ride on for lawns. I am hosing it right now. Most of my lawns are between 5k-15k small ones, so I am even debating if I should purchase a junior or perma. If I were to though, would either one be able to go over rail tracks. I have some bigger bareground accounts that only want glyso sprayed every month or so along tracks or roadsides etc. would any of these machines be capable of driving some rougher than usual terrain?
