Looking to add a new mower to my 36 walk behind. I have a friend selling 2004 scag 52 hydro walk behind with 128 hours. Will sell it to me for $4000 including sulky and 5 x 8 trailer. I know it has been taken care of. Or do I go with a 2005 48 inch tiger cub for $5900. I only cut residential. I had initially been interested in a ztr because of easy height adjustment and convenience. Any thoughts would be greatly appreciated.
