Walker is the best machine on my rig! If you need to bag, quality matters, and space is flat and lots of obstacles go walker. Spring clean up this thing cuts the time in half with that little comb on the front, Spring we can suck up wet grass, De-thatch then run walker over and suck up the mess that makes tons of money but you definitely toss the air filter after doing a few of those. Fall wow I would never do leaf clean up with out the walker it sucks up every last leaf. But I will tell you if you want it to perform like a lawn vacuum (that's what it is) you have to keep the screen clean and use different ones for different conditions. lots of grease points but they all almost require about a half to one full pump also you need to open it up and blow it out depending on the conditions only a good operator should use it you put morons on it they will destroy it. When you buy it get the efi 48 deck dual rear wheel both screens put tubes in the rear tires bigger hopper bigger blower it saves fuel and starts every time I have 1,000 hrs on our walker in 2 years we use the crap out of it. Last Christmas eve we were sucking up leaves with it and the snow that was falling with it.
