Pipe Removal - Part 1

- This video is about my RK25 tractor and some of my thoughts. I also need some help to know if my lost of hydraulic pressure is normal?
I mention in this video that I will be removing a pipe, but I will show you the pipe in my next video. I just have a really busy schedule with work, church responsibilities and family. I try to squeeze some videos in when I can.
Normal. I don't own a tractor yet, the RK25 is on my short list of candidates so I'm enjoying your commentary on it. I have seen other vids that advise if you park your tractor/backhoe in a garage or shed be sure to leave room for the boom and outriggers to settle as pressure bleeds out or you may come come back in a week and find your tractor has remodeled a wall! Some folks just go ahead and lower those parts to the floor to be sure nothing accidentally gets crushed. Thanks again for sharing your experiences.
I just built a pole barn and I have concerns about what you mentioned. The backhoe takes up too much room in my opinion. They should have designed it so you could put pin in so it doesn’t start to sprawl.
It's perfectly normal for the tractor's hydraulic system to lose pressure overnight. The fact other manufacturers supply some type of fastening device to "clip" the outriggers to the frame so they don't sag is an example of how normal this is. BTW nearly all modern tractor hydraulic systems produce nearly full hydraulic pressure (around 80-90%) at idle. This is why you can actually lift a full bucket at idle. As you increase engine speed, while pressure will go up slightly, the hydraulic fluid flow increases dramatically. Thus the bucket or backhoe works 'faster' and appears to be more powerful. It's the flow, not the pressure, that is doing most of the work.
If you compare specs of different tractors in the same class (sub-compact, compact, utility etc) you will notice they all state the amount of flow in gallons per minute for the hydraulic system. Often it also breaks the flow down to steering and everything else. RK (TYM) appears to divert about 40% of the flow to the steering. That seems to be the industry standard for these smaller tractors. I've heard of devices that can be attached to certain manufacturer's models that divert some of the steering flow to the implements when the steering is not being used to increase the efficiency of the various implements. I suspect it also voids the warranty.
Definitely start the tractor with the throttle set at idle, particularly when it is as new as yours is. Internal engine surfaces are still breaking in, meaning any microscopic irregularities on pistons, rings, bearings, gears etc are actually being worn/smoothed down. Starting the cold engine at a speed higher than idle can accelerate that normal wear-in process and even damage the engine. Especially when the engine is new and cold, you want to give the engine several minutes of idle to warm up before operating the tractor.
I assume you have integrated a standard "check-the-tractor" before operating procedure. Always check the engine oil and hydraulic fluid levels before starting the tractor. The key is to always check it when the tractor is sitting in the same position so the fluid level you see can be compared to the last level you saw. I park mine in the same spot after each use. It's easier to notice a fluid drop when checking if you know for certain where the fluid should "normally" be.
After I start my tractor (after checking the fluid levels) I do a slow walk around and check for obvious problems such as bent or loose pieces. It's also a great way to become more familiar with your tractor. I strongly advise you to get your socket and wrench sets out and check all accessible bolts and nuts for tightness. I promise you that you will find several that are loose. Catch them now before they round out a hole and something falls off.
I found that, on my RK37, I did not own the larger sizes needed to tighten every bolt and nut. So I headed to Harbor Freight and drop a few dimes on larger tools. Also, while the tractor is actually made by TYM and therefore should be entirely metric, I discovered several SAE (standard) bolts and nuts on the tractor. Thinking about it, I realized the standard sizes were confined to the loader and backhoe attachment points. So I assumed, since the tractor is shipped over from South Korea separately from the loader and backhoe, then assembled here in the US by RK, that the loader and backhoe came out of their crates missing some hardware and RK swapped in whatever they could source to assemble the tractor. Just my theory.
Sorry about the long comment. Just trying to pass on newbie knowledge to another newbie. Keep the videos coming.
So much information!!! Thank you! Great advice and information.
If the RK had a more powerful Hydraulic pump would it be able to lift more without bogging down?
@@letslearntogether4361 Yes....but the hydraulic pump uses engine power. A bigger pump would use more engine power. Plus the loader frame and lift cylinders are all matched to the pump output. Increasing the pump output can stress the other components beyond their capacity. While they may not immediately break, they might wear faster or the seals might break. There are many variables involved.
@@michaeltaillon2874 all things to consider.
That is as normal as normal gets.
always lower the legs and buckets the weight will slowly pull them down and growing up my dad always said it was bad for the hydraulics to leave the weight and pressure on them so I always lower them and when you turn them off move the sticks around to remove the pressure. Saw your video and watched them all because I have been looking around for a compact myself and have settled on the RK25 but will be getting the mid mower with it because Zero Turns and regular mowers don't work when you live in the mountains and nothing not even your yard is flat lol.
Thank you for the advice about lowering the legs and bucket. To lower the bucket each time means I need to remove the pin on the backhoe. That makes sense and I was doing that first but then I got lazy. I don’t want to ruin my hydraulics so I better start doing it again.
I think you will like the RK25. You get a lot of tractor for the price. If I had mountains I too would have purchase a mid mower.
Thank you for the comment and watching my video. Please subscribe if you haven’t already. I plan on releasing more videos as I find the time.
I know that a lot of us do it but starting the machine without being on it is a bad habit
Since you posted this I have made sure to warm the glowplugs each time! Thank you.
I'm no expert but my backhoe does the same thing and I think that's normal.
Thank you for the comment and support! Check out Eddy’s comment. I think he may be right. Pretty soon you and I will be tractor experts😀
