I just picked up a large Assisted Living facility that has close to 20k square foot of turf in a courtyard that is only accessible from the inside of the building. This area is heavily landscaped as well. Bagging is not an option and i only have a 32 inch wide door as an access point. I need a very good mulching mower that will do the job fast and effecient. The grass is bermuda and it is on a fertilization program. Any suggestions on brands and models will be appreciated.
