kasey54 305 #1 Posted September 24, 2018 I have decided its time for a tach ,rather than listening and hoping I'm in the right RPM range. What do you all recommend , and why? Thanks in advance. Share this post Link to post Share on other sites
ebinmaine 68,514 #2 Posted September 24, 2018 I'm going to follow this one along because I'm curious to see what the answers are as well. Are you looking for a handheld one for diagnostics or a 2-inch diameter one to put into a gauge hole on a particular Wheelhorse? Share this post Link to post Share on other sites
kasey54 305 #3 Posted September 24, 2018 One for diagnostics. Share this post Link to post Share on other sites

BOB ELLISON 2,981 #5 Posted September 25, 2018 What model and year do you want to put the tachometer on and do you want a hand held or it mounted on the tractor ? I did a post for a mounted tack that I still have on my C160. Works great still . Share this post Link to post Share on other sites
kasey54 305 #6 Posted September 25, 2018 was looking for one in diagnosing and setting maximum rpm on several tractors. Share this post Link to post Share on other sites

Google digital tachometer and you'll get everything you need. I got this one from Harbor freight and it works good. https://m.harborfreight.com/digital-photo-sensor-tachometer-66632.html 1 Share this post Link to post Share on other sites
WHX?? 49,193 #9 Posted September 25, 2018 What tractor/motor are you looking to put it on Kasey? I personally never had a use for a mounted tach. I set the high RPM for 3600 and idle for 900 using a hand held tach and run either the two. Talking single Kohlers here. Especially when running attachments. Hydros are always suposed to be running at high RPM anyway. Only attachment that I can think of that shouldn't be run WOT is a sickle bar. Just my Share this post Link to post Share on other sites

kasey54 305 #17 Posted October 4, 2018 I bought a non contact photo laser tachometer, how ever it seems in correct. I cut a piece of the provided reflective tape and put it on a good running 1725 rpm baldor motor and it consistently reads 4960 rpm. That isnt right. Share this post Link to post Share on other sites
kasey54 305 #18 Posted October 4, 2018 Are there any pit falls? I thought maybe the the keyway may have been acting as a second reflector, so wrapped the shaft with masking tape, painted it black and put another piece of reflective tape on, and had the same results. Thoughts please. Share this post Link to post Share on other sites
WHX?? 49,193 #19 Posted October 5, 2018 The one I got off ebay is kinda like that Kasey. Real inconsistent .... the non contact works for crap but you can also use it for contact as it came with a rubber tip you can put on the end of a shaft. Still a little inconsistent but (sometimes) useable. I think they saw me coming. Share this post Link to post Share on other sites
kasey54 305 #20 Posted October 6, 2018 Upon redoing my test I discovered (read instructions) the device gives three readouts. Highest, lowest, and final rpm. The final , or 3rd readout seems spot on. It also wants .8 seconds of read time. Im much happier now! 2 Share this post Link to post Share on other sites
edgro 677 #21 Posted September 15, 2019 this came from ebay, less than $10 delivered. Not necessarily a recommendation, but within my cheapskate budget. it seems to do a lot of hunting to find is mark, but it did work, and I was able to adjust the governed speed. (it was around 3800) 1 Share this post Link to post Share on other sites
prondzy 3,882 #22 Posted September 15, 2019 Search ez tach plus i have the matco version it works great! A little spendier than ones suggested already but it can be used on 2 and 4 stroke engines 1-4 cylinders, easy to use and has a non contact reading or you can use inductive clip that goes on the plug wire.
