I have an 18/44 with a Honda engine. The dealer said that it was a residential mower but, I may need it to mow about 5 acres. It looks like I will be laid off from my job soon, I was wondering if there is anything special besides the normal maintenance that I should do to the mower. It only has 7 hours on it right now. I have herd of people getting burn marks on there lawn when they stop. I put the throttle in idle when I stop and I havent had too many problems with burn marks yet. Thanks for the help.
