is there a reason that no manufacturers make a hi-wheel rear wheel drive wb. i don't need anything commercial. i have a hustler to take care of my yard. i only need a wb for about 200ft of ditch that will take about 4 passes. it definitely needs to be high wheeled. my w-m special 5hp murray push mower is about shot. i can't justify commercial for that small of an amount. i have searched and found rwd wb, but they have small rear tires and there are plenty of high wheeled fwd, but nothing that combines both. i have seen an ariens that has rwd and mid sized rear tires. it is about $600 with a kawi.
