Well I got a new (Used) Ferris 48" Dual hydro walkbehind yesterday. This thing is mint. I paid $1600 for it. This is my first hydro so after bumping the garage door twice and allmost running myself over going reverse I got the hang of it. The Mower was repossesed once so it sat around for a while. The thing has lots of power and everything on it is like new. I will have to do my home work with it to be better with controling the hydro drive. I am so used to pulling the handles of a belt drive hard so a hard tug on this baby sends her flying in reverse into me. I also got a Shin T230. Man was i having a good day! This trimmer is nice and runs so smooth. Quik question, do new trimmers need to be primed? The dealer asked me if I new how to prime one so I just let them do it. All they did was put gas in it, started it, let it run for a minute then slowly went to full throtle for another minute. Is that nessisary or did they just want to break her in?
