I have a riding tractor with a 50in blade. It takes me about 4 hrs to mow with tractor, then another 90 minutes with the hand mower. Then there's the flower beds to mulch and weed, it's endless. I have a herd of deer I feed, but they don't eat much grass ( they prefer my flowers! ) I keep telling my dogs they need to start doing yardwork. I don't know if I have ever seen a Coach Musette bag, did you find it on Ebay?I haven't forgotten about your Bal bags either! I can't even imagine having 7 acres to look after. It's just coming into Spring here, and I have spent the last few week-ends weeding and mulching my front garden on my 1/4 acre block. That was exhausting enough, and I know all the weeds will just be popping back up soon enough. It's nice to see the spring time flowers, and I have a few lizards living in my garden and they like to watch me work!
I hope you have a ride on mower, or maybe you could consider some sheep or goats to help keep the grass down??? As long as your dogs wouldn't mind
