I was wondering too if the double blade set up would wear out the spindles faster and make the engine work harder. And too with the blades being expensive and sharpening time consuming. Wouldn't that be just more work and expense? Or does one set of the blades last longer this way? I want to try this set up. But with the profit margin the way it is. On the other hand if you just had to go over the high grass one time it might save money in the long run. Just trying to decide. Maybe I should just do it. Right now i am not having any complaints about grass clippings.

i run them on my 36 inch toro. i put the gator on the bottom, cause i have 4 sets of gators, one set of high lifts. the cut is great. it seems like the higher the grass, the better the striping. I cut 8-12 inch grass yesterday, and i didn't have to double cut. there were clippings visible, but no clumps. There is much less gunk collected under the deck with the double blades. i wanna try 2 gators, 2 high lifts, maybe 3 blades, but that would put the cut pretty low. The last guy mentioned profit margin and extra money spent on sharpening, blades, and maybe gas. If your running your business right, with high quality customers who pay well, and want good work from you, your profit margin should be comfortable-great. And I really don't think that the marginal expense of blades and sharpening is gonna affect your profits, they shouldn't be that thin. I think the double blades will enable me to get the good customers i want

Ok so I went out and put the extra blades on. Gator on top and high lifts on bottom. Did part of my yard. 1 and1/2 inches the blades cut into the ground on a small ditch area same as 1 and 3/4. The drag on my 23Kohler lazer seemed like way too much so I took them off. It really dragged when I first kicked the blades in. But is was wet outside and the part i cut looked good and the grass chopped up good. oh well. maybe I just need a more hp and cut higher

A couple of you mentioned spindle wear because of the double blades. I have used double blades like I said before, for around 12 years now and I have never replaced a spindle bearing. The DC I run has 2,704 hours on it and every hour it's been run, it's had double blades on it. The main thing is keep them sharp and balanced and the spindles greased and you shouldn't have spindle bearing problems.<p>Jason: No I'm not a God, but I do like to try to make the job easier by trying different things. <p>Paddy: You mention trying double Gators, I've done that too, works nice on chopping leaves, but you don't get enough lift with them for cutting grass. They might work OK on your machine though. I have even used double Highlifts. You can throw clippings for many feet with them, but it will pull the heck out of an engine.<p>Charles: The 23 Kohler should have plenty of power for double blades. I run them on a 20HP and a 22HP Kohler and 60&quot; decks. One reason you seem to be cutting lower is, the bottom blade will cut 1/4 inch lower, plus you have a lot more lift too, to pull the grass up to get cut off. Raise the deck up a bit.<p>If I missed anyones question, sorry, I'll try later. Happy Mowing

Am using the 2 blade set up on 23 hp lazer and it is truly remarkable. However, if you hit anything( a rock for example!!!) the blades are a real sob to get off. Im real interested in a device to keep the blades perpendicular. Im also going to but my deflector back on because the thing is discharging clippings over 2 rows-10+ feet!

Dingo,<p>You should be fine with your 19hp. My 52&quot; Lazer has the 18 hp Kohler. If it isn't warmed up when I engage the blades it'll kill the motor. It'll also kill motor unless I have it at full throttle before I engage. It really drags the motor down to engage the blades. But in a second or two, it's running wide open and fine.<p>I removed my mulching kit when I went to double blades. But I'm still experimenting with different combos.

Dingo, My 20 HP Kohler will run them on a 60&quot; deck, so a 19 HP should do it too. I'm guessing you have a smaller deck with a 19 HP. I use an open chute on mine, but the clippings come out like they have been mulched.<p>Crew, a device to keep the blades perpendicular will also tighten up the blades if you hit something solid. I feel your better off without one, this way there is some give in the setup if you do hit something solid. <p>----------<br>&lt;a href=&quot;http://www.townserver.com/elm/&quot;&gt;Eric@ELM&lt;/a&gt;<br>

What if you tack weld the blades together to keep them at an X pattern? (Assuming you never want to go back to single blade mowing.)<p><p>----------<br>D. Tom<br>

D Tom, That was my theory back in 88 when I first tryed it on my JD 50&quot;. It made it harder to sharpen them for one thing and I was mowing an empty lot and hit a rock and the blade broke off where the weld was. It will weaken them. I'm just glad it didn't happen around people and I was very lucky. Take it from me, Don't Weld them. It is so rare that they move. All you have to do is loosen the bolt and adjust them. It's not that big of a deal re-adjust them.<p>----------<br>&lt;a href=&quot;http://www.townserver.com/elm/&quot;&gt;Eric@ELM&lt;/a&gt;<p>
