I have a SMWC-61A. Somewhere around a 2007 model. Last season I was losing hydraulic fluid from somewhere around my right pump. Kept an eye on fluid level and had to add cardboard to my shed floor for leakage. So before mowing season starts again, I want to either fix or dump this mower. In the past few years, I have replaced a ton of parts on this thing. Last year's adventure was a new electric PTO clutch. I'm 64, and crawling under this thing is getting old, and nearly killed my back. I digress, sorry. I'm looking for advise on repairing or placing this hydraulic pump. At $600-$700 for a new pump, I'm skeptical. How hard is removing and replacing gaskets for a kit that costs $30-$40? Last option. New Zero Turn? I like the larger cutting width. I don't think I need a commercial grade mower like this one, which I bought from my deceased brothers-in-law estate, and I've had for 10 years now. I have a rough yard of 3 to 4 acres to mow. If new, I don't want cheap, that will not take a beating for another 10 years. Been looking at Toro 55" to 60". I would like to get another couple years out of my Scag, due to resent repair and replacement items. But if the gaskets don't cure my problem, I'm thinking I should cut bait. I know it's not easy to give advice on the unseen, but I would like some input from my large yard mowing brothers and sisters. You have been a fountain of great information since I've found this site. Thank You All!
