gave those how [Applause] [Applause] hey guys welcome back to the channel I thought I'd make a video today about a subject that has came up from time to time on the track to form over on Facebook and there's a lot of different opinions on what to do and what not to do in the respect to where you should run your rpms on your tractor whether it be a Kubota tractor John Deere LS Mahendra Massey they're all more alike than they are different so you can pretty much guarantee that this is for every tractor brand out there a lot of people may say that this is merely Dave's opinion and in some ways it is Dave's opinion but it's based off of information that I've gotten through the manufacturer and through the manufacturers literature and through the owner's manuals so you know it's always good to reflect back on your owner's manual you know the numbers that I'll throw out will be basically pretend to my model tractor and I may not even throw out a bunch of numbers because it's kind of kind of irrelevant I guess you'd say to the overall scheme of things but there's a couple important things that you need to think about as far as running your tractor where to run your tractor rpms when you're when you're operating your tractor and when your chart is just sitting still and that type of thing now some model tractors safai that they want you to start the tractor at half throttle my specific model does not specify that so generally I start my trailer at all the way Liu throttle and that's just the way I've always done it so there's nothing in my manual that says to do it otherwise I have heard from folks and unless they're miss reading their manual because I'm not gonna go through and read every tractor manual there is out here they're saying that their tractor master manual specifies that they start their tractor at half throttle that make a lot of sense to me but it is what it is anyhow I start mine at low idle mine is an HST transmission hydrostatic drive transmission our PMS is very very important on a hydrostatic drive transmission because the transmission is operating off of the flow rate and the flow pressure of the hydraulic system and if you look in your owners manual on the specifications table page you will find where it has listed under the engine that make model type number of cylinders bore/stroke total displacement engine gross power engine net power and rated revolutions per minute now that's a very important one the rated revolutions per minute because everything else in this manual about this tractor is based off of that number the rated revolutions per minute that means that the horsepower of this tractor the gross and horsepower of this tractor is is calculated when the tractor is running at the engines rated rpms for this specific model tractor the rated rpms is 2800 rpms now if I look at my 540 more my 540 mark is nowhere near 2800 rpm in fact my 540 mark is 23 to 24 hundred rpms they give you that slot 2300 to 2400 rpm is 540 at the PTO now the way I feel about it and from everything that all the information I've gathered throughout the years there's a couple things that needs to happen you need to be at a minimum of the 540 mark when you're operating your tractor when you're moving forward and moving Reverse and running operations like a front-end loader and a rear three-point left it is important that you've maintained the proper flue and the proper pressure to be able to operate the transmission the three-point and whatever implement you have on the front of your tractor you can't do this if your tractor rpms are lower because the lower your tractor RPMs are the lower your flow rate is and the lower your pressure is going to be you could put a pressure gauge and a flow meter on there and you can see that so it's important that you stay at 540 or above when you're operating your tractor now when you come to a stop and you know you know there are exceptions to rule if I'm running a posthole digger on the back of this after I'm not moving forward I'm not moving backwards I'm not using the transmission only thing I'm using is a three-point lift and I want to slew that three-point lift up and down a little bit slow it down some and I want to slow down the amount of RPMs of that PTO so that arter don't spend so fast because I find it it actually works a little better for me they have it a little slower rpm so I'll drop my rpms you know for example you know my 540 mark like I said is 2,300 to 2,400 I'll drop my rpms down to 2,000 rpms to run a post hole digger I'm not moving forward and reverse I don't need the the hydraulic flow for that but even still I wouldn't drop much lower than that because you do need to flow rate B to assist in cooling the hydraulic fluid and that is very important the flow rate how fast or how slow that fluid gets pumped through that cooling radiator on the front is vital to keeping that hydraulic fluid nice and cool so I wouldn't drop it much slower than that if you know when you're when you're operating something if you're just gonna sit for a few minutes you know you can drop it down to half idle and get off the tractor and do what you need to do and and come back and get back on the tractor you know anyhow that's my thoughts on the tractor rpms and where they need to be and that's my story and I'm sticking to it if you have any questions leave them in the comment section below hopefully I've covered everything and this video hasn't gone on too long to be too boring but I think it's something worth touching base on and your owner's manual there's no replacement for the owner's manual look in your owners manual find out we raided engine rpm or an owner's manual and that's really where you need to be running your tractor at unless you've got a PTO driven implement on the back like a brush holders finished mall or something like that you know or under mid mount mower deck or something of that nature then of course you need to be at the recommended rpm for that specific implement in the case of the rear implements the 540 range is where you need to be at so you know really the only time you would be running below the rated engine RPMs would be when you're running at the 540 mark would it hurt to run the tractor at the 540 mark all the time no it wouldn't hurt it at all the tractor is designed to run efficiently enough at the 540 mark to be able to handle the load of a brush hog which can really put a lot of load on a tractor and still not overheat the hydraulics and have plenty of flow for cooling and whatnot so you could run it 540 and be safe I personally like to run mine almost at the 2,800 mark it just recommends for the rated engine rpm I typically run about 2600 RPMs just to give you an idea my rate at rpm is 2800 but I typically run at 2600 if I'm doing Box bleed work front-end loader work stuff of that nature 2,600 RPMs is where I'm running if I throw the brush hog finish more rotor tiller or something like that on here then I'm at the 540 mark if I'm got the post hole digger on here I drop it down to 2,000 rpms which is my 540 is between 2300 and 2400 so I'm only dropping it down 300 rpms to run that post hole digger and that's not enough to to do any real damage because I'm not using the transmission to move forward and backward because I'm just sitting there digging a post hole you know and it makes it a little bit more controllable so anyway hope it helps appreciate you guys watching my channel I know it's been a long time since I made a video you know just what can I say I just haven't really been into it I haven't had the spirit hadn't moved me to make any actually I have been working on several different ones and I just didn't like how they turned out so they get put on the back burner and I hate to go back to the drawing board or they never get published so but there there are a couple that that I've been working on you know I've got another video coming of the super shaker soul sister I did some some sifting with that thing a couple days ago and man that is not a nice machine to have I'm so glad that I went ahead and finished building that thing that was a long project going it took me several years to build it because I just kept you know I had a lot of things going on and I just couldn't stay on it but I'm glad I finished because it's been a lot of fun to use and a real joy to have I'm glad that I've got it so anyway stay tuned to the channel I appreciate all my new subscribers welcome to the channel seems like the subscriber count is definitely growing and we have a great tractor community here if you look in the comments under this video you will see a lot attractive guys with tractor channels that comment under this video and go to their channel subscribe to their channel check out their content and see if there's something that you would enjoy I'm sure it will be because all the guys that watch my channel that have YouTube channels really do create a lot of quality stuff but always impress with what I see on so many of the channels I could sit here and name them off but man we'd be here all day so thanks for watching have a great day don't get the rate comment subscribe thanks for watching
