Im working on a 2014 Toro XT6715-2070 149cc engine where its having issues on warm up. After starting it will run well for about 30 to 40 seconds or so then start to stumble for about 10 seconds, then runs OK for about 20 seconds, then goes back an forth doing this for about two and a half minutes then just starts to run well from then on. After its ran for about 6 minutes it still does not fully open the choke butterfly. The carb is a new OEM carb and I pulled the fuel filter to eliminate any possible issues with fuel restriction. The air filter is also new. Iv had this on other identical mowers and have not yet found a solution. The choke is one of these that mount directly the muffler and is the size of about a fifty cent piece that mounts flat on the muffler. It does not appear to be adjustable in any way. if I hold the choke rod open fully I do not experience this issue. Im sure Ill see this again so if anyone has any information for me that would be most helpful.

> Gary--are you using a mulching more or a regular mower? Yes, a mulching rear bagger with a spring loaded flipper. Another reason I do not mulch is that I have Merion Bluegrass. It is so easily diseased, I need to remove (sick) clippings. Merion is also prone to thatch simply because of the very high nitrogen it requires too.(@ 6lbs X 1000ft2 each year) It's a catch 22. Personally, I think my self-propelled mower travels too fast to mulch properly. Merion is so thick, that before the blades can get mulched fine, the machine is chomping forward for more. If I disengage the self propel, I do get my work out, making my doctor happy I guess! I was considering trying a Gator blade. Maybe then, my mulching would look better, but I'd still be contending with disease. Bestlawn will probably suggest that R word for my Merion :-)

Couldn't open the ad; what did you get it for? I paid nearly as much for shipping as I paid for the deck, but it was worth every penny. I've used it four times so far this year. Spectacular cut. One incredibly nit-picky criticism is that while mowing my hybrid Bermuda at my standard early-season height of 1/2", the bolts which hold the discharge shoot to the sheet metal stick down 1/4" or so, so when I hit some slight bumps, they tend to scratch the turf. It's not an issue while mowing at 3/4", so I guess I'll just have to mow a little higher. Still looks like a putting green out front. Tomorrow I'll put it to the test. I've been a little busy lately, and the common Bermuda out back is about 1.5-2". I cut the common variety at 1". I haven't seen any clippings after mowing. The only difference between mulching and bagging is that my dog tends to track fine particles of wet clippings in the house after doing his business on the wet morning grass. But I can live with that for the benefits: recycling my clippings into the grass, no more dust cloud discharging behind my head, and a darn nice cut.

I've never run the Piranha with the deflector removed. Not sure how that would work out. I currently have the mulch deflector installed (M120965) which, unlike a "mulch plug" does actually allow a slight discharge of clippings. There is also a rear discharge insert (M120966) available which you'd swap out with the mulching discharge chute, if you want to use it as a conventional mower. I'd guess it increases the airflow volume by about 3x, and I'm sure it would still mulch quite a bit, with six blades spinning over a 44" swath. If you read the US patent description, the original intent was that a homeowner could easily convert this deck into a neglected-grass mower for certain situations like returning from vacation. Go to the JD parts catalog (link below), click on equipment search, type "deck" then scroll down to "mower decks for LX, GT, etc... Click on Sectional Index, then "44 inch mulching mower." When you open up the "mower deck, chute and gage wheels" view you'll see what I'm talking about. The Piranha will cut high grass. You just might have to go over it twice to mulch it completely. But it's not like your mower will become ineffective if your grass reaches 3". I previously owned a Cub Cadet with a mulch plug in the convertable deck. If the grass was too high it would basically clog up and leave about a third of the pass uncut. The Piranha doesn't do that, as far as I've seen. It just leaves clumps of clippings atop the otherwise evenly cut grass--if I let it get too long. Second pass elminates it completely. As long as I cut once a week, that doesn't happen. I sit and think of all the time I wasted bagging and dumping grass clippings (and unclogging the chute). Now here I am, with the same end result (minus the 4x8' compost bin), and the organic matter is instantaneously recycled into the soil. What a great purchase; probably would have been worth paying retail if I hadn't come across such a good deal. Nah, I'm too cheap to drop $900 on a mower deck. That extra $600 on top of what I spent buys a lot of Yuengling Lager and strip steak 5-packs from Sam's Club. I'd probably have to switch to Milwakee's Best and eye round steaks this summer if I'd paid full retail. Here is a link that might be useful: jd parts catalog
