I just sold my little Kubota B6100D tractor and yesterday went to purchase a 1983 Kubota L275, which I'm super excited about (see picture). When I arrived, the guy selling it started the machine without any problem whatsoever. After it ran for about 45 seconds, I turned it off so we could chat...

I just took an order for a set of category 2 3-point hitch forks, but I can't seem to find how high to center the lower link pins from the base of the implement. Does anyone out there have a category 2 3-point hitch on their tractor that would be able to tell me how low their lower link arms go...

I am having trouble with the 1978 Kubota B6100 that was just rebuilt. I did a complete overhaul on the motor, and after running it for about 2 weeks this past winter, the rear main seal went on the engine, allowing engine oil to pour out of the starter when you ran the engine. From what I could...

I recently completed the engine rebuild on my 1978 Kubota B6100 and have just barely been able to put it to work with snow removal (we've been getting pounded in the North East). It takes me a couple hours to clean my driveway with this little machine and this morning the tractor started...

I have sorted the hydraulics for the loader due to the help of a tractorbynet user. I had the loader valve and rear auxiliary hydraulics valve in parallel instead of series, so it was a simple fix to get the that taken care of. Here's a link to that discussion...

Your posting makes perfect sense! Of course the valves would not work in parallel. I just ran out to the shop, dug through my bucket of fittings, and welded up the fitting I needed to connect the loader valve outlet to the valve inlet line for the rear auxiliary hydraulics. I also plugged off...

I wonder if the way I have the two valves plumbed in is causing the problem. I have attached a diagram to show how everything is plumbed. As a note, I had the rear auxiliary hydraulic ports installed before I installed and plumbed in the loader. Before all these changes, the rear ports worked...

Hi All, I have been posting info and pictures about a Kubota B6100 that I mounted a Kubota LA302 FEL on. I also rebuilt the engine on this one, but that really doesn't matter here. My problem is that the auxiliary hydraulics I plumbed in for the loader, and rear set of hydraulic couplers, are...

I finally dragged the loader arm assembly into the shop and mounted it up. I also have started working on the wiring. The machine now has a new ground and positive battery connection and I really just need to clean and re-wrap the wiring harness before installing it. There are only a few things...

So my fabrication shop has been super busy, and time is money, so I decided to hunt down a local place to do powder coating. I found in place in Bow, NH by the name of RS Powder Coating and brought a batch of parts to be coated. I picked up the batch of parts and the work is fantastic! The price...

I've made good progress and this project is very near completion for the winter, as I need it to plow snow with. The loader mounting frame has been mounted up, the auxiliary hydraulics have been fabricated/plumbed in and I'll be picking up a batch of powdercoated parts on Friday (and dropping...

I finally got to get some final paint done today. I'll be able to paint the underside of the main mounting brackets, along with the remaining parts of the connecting bars and front frame on Wednesday. I should be able to bolt everything to the tractor next weekend. I can't wait to make this...

More pics of progress

I've gotten some more work done. I've welded in a bung to mount the block heater (right on the bottom of the radiator so it's well protected and out of the way), built a new aluminum grill (1/2" square stock frame, .120" perferated aluminum sheet with 1/2" holes, and 1" round aluminum...

Hi everyone. I know that this isn't an exciting thread, but does anyone out there in the northeast have a Kubota LA302 front end loader that would be interested in trading my 55" wide bucket for a stock 48" wide bucket? I'm currently mounting the loader on a little Kubota B6100, and this wide...

I saw this thread quite some time ago and have been wanting to share the pictures of the 3-point hitch crane (technically a jib) I whipped up to use on my little B6100's 3-point hitch this past fall for putting up trusses for my shop building. It sure does look funny to have a 24' long piece of...

Hi Darryl. The RT5000 is still in the shop. The engine's all assembled and installed, but this Kubota took over my time when the parts for the engine rebuild arrived (I waited 3.5 months for all the bits) and I need to get it done and the front of the machine (engine, subframe, and loader...

Here's some more pics. I'll be back welding this evening.

I purchased a used Kubota LA302 FEL about a year ago and I finally have had time to work on mounting it on my Kubota B6100 tractor from 1978. The vertical bracket plates and rear axle mounting plates were cut out about a year ago, and just this fall I'm having time to get everything mounted up...

After a 9 week wait, the pistons, rings, bearings, gaskets, seals, and coolant outlet/stator mount have all arrived and I've been able to start reassembly. Of everything in the kit, the only thing I was unable to install in my shop were the top connecting rod bearings, as they are very thin, and...

The engine is now all back together. As always, Sanel's Machine shop in Concord (NH) did a great job with the bore job and they got it turned around quickly (I've had the block back for about 3 weeks now). The engine is now basically new. It has a new crankshaft, connecting rod, piston, and...

Hi Darryl, Thanks for the compliment. I've been TIG welding professionally for 13 years now and I use my TIG all the time. Aluminum isn't hard, it just requires patience. As far as parts go, I'm actually also the online parts manager at Freedom Cycle in Concord, NH and we sell parts for these...

The case has been fixed and is ready for an over-bore (0.25 mm should do it; the bore doesn't show much for wear). I've posted pictures of the fixing procedure below, but none of me actually welding (I can't do four things at once, only three :) ). The first step is to press the case back into...

I cleaned the block and found a good size crack. It's a 20 minute fix and it'll be welded up tomorrow. This is probably the easiest broken case weld job I've ever had to do. I'll post pics tomorrow.

Here's the problem! I was close with my guess of 5 pieces for the connecting rod, but I'll say I'm right because of the part of the piston that I dug out as well. I was hoping that the crank was usable, but it's toast as well. It looks like I'm in for a piston, connecting rod, crankshaft, and...

I purchased a Honda RT5000 4x4 subcompact tractor a couple months ago and I was told it had a seized engine. I finally got to start the tear-down last night and I figured I would share the project with the folks here. I've attached a few pictures of the machine to show where I am right now. So...

This past fall I built my shop building and it has 10' walls and engineered trusses that make for approximately 20' of vertical clearance in the center. The building is 24' x 32' and I won't be heating the building, so I wanted to install lighting that wouldn't be effected by the temperature...

B6100 failure update: It's been a bit since I've posted, but I've made some good progress on fixing this problem. The engine has been removed, fully disassembled, professionally inspected, and bored 0.5 mm over (first over bore for available pistons). As suspected, the cylinders were out of...

The design has been finalized for our category 0 3-point hitch forks. The lower link pins have three different sets of holes that are centered 8", 10", and 12" to the base of the implement. With the three different mounting hole locations, they will fit just about any cat. 0 setup. They come...

I have a 1978 Kubota B6100 and I seem to have 12+ volts between the positive terminal of the battery and the electrical connection of the glow plugs at all times. Is that a bad thing? I'm trying to sort our why I can't get my machine to start. The glow plugs are brand new, the fuel lines are...

I am starting to design a line of category 0 3-point implements, but can't find a machine locally to get one of the dimensions I need. On the Category 1 implements we build, the lower link pins are always 5" (on center) from the base of the implement. Would anyone out there with a category 0...

I have a 1978 Kubota B6100 Manual shift 4x4 model and I've been trying to hunt down R4 tires and new wheels. Someone posted info about a B6100 rebuild back in 2006, but I have not been able to get in touch with him, even after several attempts. My machine currently has almost worn out turf...
