Hello, what an expression. I have to repeat it: "Double Pilot Operated Check Valves". I have a rough idea what they do, how they operate but not really why they are needed. I do not want to mess up other threads where people have specific questions, so that's why I openend a new thread. As...

Not really off-topic, but I found a few fake tractors that sneaked into this forum :giggle: There are probably more hidden that escaped the sharp eyes of the moderators :giggle: Who found others? Kubot https://www.orangetractortalks.com/forums/threads/b01-for-me.77315/post-815404 Kubata...

Hello, the camber on the front wheels of the G1900 is positive, about 3 degrees although it looks more. I would like to change that but not before understanding why it was done this way. As opposed to a pretty ignorant member of this forum I do consider Japanese engineering top class in...

Hello, are there hydraulic pumps available where the shaft being driven comes out the other side? Could be female spline as well. I looked for "hydraulic pump dual shaft" or "hydraulic pump through shaft" but very little came up. Found a few PTO pumps but their speed was too slow. So what are...

Hello, my friend called me with his tractor broken down in the woods. "Release PTO" was the error message in the display. Turns out this was totally wrong, the fault was fuse 12 "key stop". We replaced the fuse, tractor started but died a short time later again. I am looking for schematics for...

Hello, I am repairing my G1900 and I am creating the decals at the moment. Unfortunately part of the sticker in front of the seat (Warnings and start instructions) is damaged and the last sentence is missing. It is in English and French language and the number is 66120-47132. I would...

Hello, when mowing yesterday I noticed that the starter did not crank as fast as it should. The battery is not being charged. The generator has output voltage, so it must be a connection problem. I have schematics but that is for the earlier models with the dynamo and the external regulator...

I am looking for protective covers for 1/4" hydraulic connectors which is the size used on the tractor. I bought a bunch of covers and although they fit very nicely and do their job when the hydraulic hose is disconnected they are too loose to stay together when the hose is connected and hence...

Hello, I posted that question already in the "Tractor Operating" forum which was probably the wrong place. Does anybody know what oil the rear PTO gear box needs? Is it 80W90 type gear oil or more UDT type hydraulic fluid? The rear PTO is rarer than the three point hitch on this tractor with...

Hello, there was a rear PTO for the G1800 / G1900 tractors available. It is driven by the splined shaft coming out of the auxiliary pump, contained a clutch and gear box and the clutch was operated with a lever on the left hand side of the seat via a wire. What I am looking for is advice how...

Hello, my floor panel has been butchered by one of the previous owners to fit a (non-fitting) cabin. I bought a second hand one that I want to do up (came in two halves, but that is a different story). What I noticed is that the floor is pretty much level whereas mine (left) has a kink in the...

Hello, I did a bit of searching already but strangely enough could not find a definitive answer. Am i right in the assumption that the size of a u-joint with internal clip rings is the inside width of the yoke and with u-joints with external clip rings the dimension is the overall width of...

Hello, when I cut the grass at the site boundary last night, the neighbours fencing wire got caught in the wheel studs (he used strong wire, so I noticed before any damage was done). I had a look at it today and the studs are indeed protruding the wheel, something I do not like. I believe they...

Hello, the G1900 has some form of engine movement limiter mounted on the engine plate rear end at front of the tractor under the flywheel (see first picture, flywheel removed). I cannot find the parts in the parts manual, it is neither with the frame where the engine rubber mounts are shown nor...

I would like to post a video every now and then, very short and compressed to smaller size than a typical picture (I am well aware of server disk space). I avoid to use youtube, so posting it there and supplying a link here is not an option. The only way I found is encapsulating the video in...

Hello, I am looking for the type of quick connect coupling that Kubota used on the small lawn tractors. This connection came from a G1900 grass collector hydraulic cylinder hose. I believe it is a connection ISO7241-A size 1. The front diameter is 11.8mm, the diameter behind the ball lock...

Hello, as a by-catch when buying a cutting deck I aquired a rotating brush. The problem is that the mount for the tractor is missing, so I have to build it (unless I can find it somewhere to buy). I did some searches on the internet and found pictures of the snowblower mount which I think is...

Hello, a friend of mine is looking for the number of a replacement left rear view mirror. I could not find PDF files and the European Kubota web site for spare parts seem to have faulty links, it always leads back to the sales presentation. American Kubota sites are censored and not accessible...

Hello, I am looking for the pinout of those pressure sensors used in Hyundai excavators like the R140 or R210 and others. Kind regards, Hugo

Hello, I would like to add a trailer hitch to my Kubota G1900 lawn tractor to tow a small garden trailer. I searched on the internet for some pictures but without conclusive results. The tractor has a plate mounted to the bottom of the differential and I have seen people simply mounting a ball...
