I dont know how things are with your customers, but most of ours will call and complain if they see any sign of mulched leaves left on their lawn. I can explain till im blue in the face about nutrient availability in the leaves but it wont work by us. They want them all taken away. And mulching doesnt work if you have a thick irrigated, kentucky blue grass lawn. You can mow over it 20 times and you will still see the leaves.
Oh and about the drugs comment, nah... ive just always been someone who tries anything to make things more efficient while spending as little money as possible. You'd be surpised at yourself sometimes- like using a $0.30 6" flexible drainage pipe as a chute extender on the vaccuum versus spending a couple hundred bucks on a real chute extender. I was reading another thread last fall about a guy who thought he got a great deal by paying $160 on one, and he uploaded a picture, and it was basically a pipe! I just kick myself in the *ss if I waste money when its not worth it. But yes, sometimes all the time wasted trying to make something isnt worth it either, but ya never know when you will invent something great, thats how everything gets invented, isnt it?
I went to the actual monster bag website-
www.monsterleafbag.com, and they are only $40. it may be worth a try next fall for $40. Even if its just doing the final cut and catch after the bulk is picked up, $40 sure beats a $2000 tow behind collection system!
