Here is a project that I am working on. Should be through tomorrow. Forgot the camera yesterday so the pics start a little after the beginning. Some of you may remember the Limb cage that I bid on...this is from the same dealer. He called needing a belly pan for a tractor he had just sold. The customer jabbed a stick through the oil filter into his radiator. The teats on the tires aren't even rubbed off good yet. They just fixed it and I am putting it on. Plate is 3/8" x5'x10'.The rough cut notch is for the tire to make a full turn. It has a lot of oscillation and swings greatly. You can see the indention on the gray part of the engine cover that they have to accomodate the tuning of the wheel and pivoting of the axle. It was necessary to notch, because the engine needs as much protection as possible. You can se the filter in the first photo that was knocked off.

Reply:Here are some more. You can see the loader control valve is a sitting duck for anything to wipe it out. behind that is a hydraulic filter, a mass of wires, hydraulic lines, and several delicate solenoids. Kubotas are quality built tractors, but their design and engineering are as bad as they come. Serious farmers won't use them because of all the claptrap and stuff literally hanging off the tractors , begging to be knocked off, with some scant little 18 gauge sheet metal gaurds barely protecting vital systems. The close ups are of the front plate that mounts to the front of the tractor, slanting down and is welded to the belly pan to protect the front of the tractor.

Reply:The full plate weighs about 750 pounds. Trimmed up, I guess more like 400.There are three drain plugs. One for the transmission/rear end, and two for the engine(it has a deep U shaped oil pan for the front drive shaft to attatch to). A small hole will suffice for each, no more than 3" in diameter, enough space for a socket and fingertips to operate in. All filters are mounted on the side, and above the pan. Zerks are pointing straight out so nothing is covered up.I finished the most of the attatchment points in the dark tonight. But the last pics are the front attatchment, bolting up where the brush gaurd/ weight bracket will go. The others will bolt to the engine frame and will share in common the loader to tractor mounts. The outermost mount will actually be to the loader itself for support.If you look at the pics, you can see little yellow lines. These are the places for the attatchment points to be welded. Above them are the bolts where they will be attatched. Most should be visible if you get out your cheaters.Last edited by lugweld; 01-15-2009 at 10:36 PM.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
Reply:I see the yellow lines now!!Sounds like the oil pan is like the one on Mom's old 89 Crown Vic. 302 V8. Had 2 drain plugs, front, and back with a sorta horseshoe thing in the pan to fit around the axle, or crossmember, or some damn thing.Is there a way to enlarge the holes under the drain plugs. That damn oil has a mind of its own when you first open the plug. Sometimes it goes as much as 6" out of plumb when it first starts comin' out. That sh#t might be runnin' all across the belly pan, and over the side somewheres."Any day above ground is a good day"http://www.farmersamm.com/
Reply:If I remember right,the drain plugs on these tractors extend down sort of like a funnel to the plug and seem to drain well. I think everything will be alright, but the plugs will only be an inch or so from the opening of the hole.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:Sandy, That is a problem that is common with Kubota. No one designs the tractors from an experienced point of view. It must all be done on computers. I doubt if the designers could actually even get one of these beasts into gear. The shifter is on the left down below the seat. It really is a range selector. It has a clutch pedal, but it is a hydrostat. The forward reverse pedal is tied into the throttle so when you hit the forward or reverse rocker pedal, it automatically increases engine rpm. It does have a override though, just down and just out of reach on the right. The rpm lever is set up like a lawnmower on the dash I could go on and on about the poor designs. It is hard to believe the quality that goes into everything and then you see the design. They are paradoxical.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:Made progress today. Need to remount for final fit and drill and tap holes for access plates to the drain plug so they can be screwed back into place on Monday. Too cold for the paint to dry. Notice in the last pic on this post, the "junk" hanging off the tractor and particularly the filter placement is inches in front of the wheel and extends out into the track of the wheel area.

Reply:Here are some of the pics after I removed for painting. I had some industrial enamel I mixed up for another project, completely unrelated to this one, which I hadn't painted yet. I knew I had enough paint for both so I used it to save money. The dealer said any dark color was fine, particularly black. I had this paint custom mixed for direct to metal industrial paint from Sherwin Williams. At the time I had played with the color for the other project until I came up with this custom mix. When I opened the can again today, it hit me dead square between the eyes...It WAS KUBOTA GREY!!!! An EXACT match!!! Besides finding what a poor job I did on cleaning out my spray gun from the last time I used it, the day went well. Final post Monday I hope...

Reply:Looks pretty good!! Will the froont grill guard still bolt on??Theres only one other thing I would do, trim that sharp edge off of the mounting tab. If he hits something like a stump and the pan shifts a little it will cut a hole in the filter.see post 20 5th pic.

Reply:Thanks for the suggestion G3, but the way the particular tab is fixed, there can be no movement forward. The only way it will shift will be a catastrophic event great enough to break the tractor in half, which in this case I don't care about the filter. But if you examine post 21 pic 3 you will see in the far left, mid part of the picture between the forks, I believe, I welded a "shield" to protect the filter from any debris coming over the tire or any thing that might wedge itself in there between the tire and the filter.Yes, the front grill gaurd will still bolt on. In fact, it will take less than ten minutes to take this pan on and off. The only alteration that has to be done to any part of the tractor is the mounting brackets have to have longer bolts to accomodate the 3/8" plate.Last edited by lugweld; 01-17-2009 at 11:00 AM.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXTCraig, you simply drive over it.

Reply:Nice work Lugweld.I don't know what the protection goal is, but I'll mention that some pans even cap the service points with flush fitting plates and recessed bolt heads. Some pans use larger separate access plates, which are dropped for maintenance.As seen in post#20 picture #2; I wonder if the skid plate's protruding points near the tractor's step should be trimmed and/or capped? The problem is that the protruding points could cause a high stress point, which could lead to the door glass spontaneously cracking or breaking out completely... depending how deep the plate stabbed into the operator's shin Good LuckLast edited by denrep; 01-17-2009 at 12:58 PM.

Reply:Denrep, Yes the holes will be capped so a stick doesn't work its way up to the vitals through the hole. Its unlikely it would but Mr. Murphy always hangs around tractor dealerships and follows their customers home. He already has enacted his legislative powers upon this machine to a nice taxing sum. If you look at post 21 pics 4 and 5, you can see two painted plugs laying on the floor. These will be attatched to two holes drilled and tapped on either side of the main hole via a piece of flat bar welded to the back with matching holes for the screws.As far as the cab door cracking, It "floats completely inside of a rubber trim piece. Additionally, the cab is independent of the frame and is rubber mounted to isolate it further. All points on the pan are connected to "hard" points on the frame or pieces that attatch directly to the frame.Craig, loader to which the outer most mounting tabs are connected must "fit inside of the wheels due to the quick detatch nature of this loader. The loader actually detatches quickly by a pull of a pin or two and by releasing of the hydraulic couplings. The operator then drives out from it or in to int depending whether it is on or off. The loader base barely raises off the mounting posts when this happens, The dimensions are roughly the same as the mounting tabs on the pan. To sum it up, it was by design, but had an element of "lets see if this works the way it should." to it when I backed the tractor off.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Along the wide portion of the plate under the steps, it could bend. A couple of one inch spines would convert it into something Arnold couldn't bendI'm thinkin' that you coulda dropped down to 3/16 plate, with well placed stiffeners, and it would have been just as stout, if not more so.Don't get yer boxers in a bunch.

Reply:Samm.1/4 was considered with more reinforcements.However, when I saw so many wires, hanging out, I started thinking about all the trash and garbage those gussets would trap and hold. Mix in a little grease, oil and decomposing organic matter, you have a recipe for a fiery end to a little orange tractor. and possibly its operator.The customer wanted something clean and easy to maintain, take on and off, (yeah right) etc. That's when I decided to use 3/8 plate. It was only 308 bucks for a 5x10 sheet. Total material cost including paint is only 425 dollars.The completely unsupported jutting out part, is not as much as it appears in the pics. Only around a 8-10 inches.Last edited by lugweld; 01-18-2009 at 12:40 AM.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:Well Samm, if its any reassurance, I did jack the tractor up on that side and in the middle on the pan and had absolutely no give.But the pan is there for protection and energy absorbstion. Too much strength transmits the shock back to the tractor, making for some back wrenching blows. Maybe that will be its "crumple" zone. But as I said, that is plenty of strength, with only eight to 10 inches of overhang. There is more distance than that between the mounting tabs.I think I understand leverage. I grew up in the bulldozer business.

Reply:Well, the LugWeld Shin Buster 2000 will be put in service on Monday. We will see...Sparky, I am not completely sure of your question, but I will try to answer.Do you mean how did I get the plates to line up with the mounts? Easy. I positioned the pan into place once, I had made the measurements and the cuts. As you can see in the original pictures, it is being held up by blocks. I leveled and centered it under the tractor. I made the front mounting plate with the bolt holes my using a template method. Then I mounted it and made a measurement to link the front mounting plate to the pan. I cut a piece of metal and then welded it between the pan and the front mounting plate. The other mounting tabs were fairly easy, as I generally would paint the bolt ends with a yellow valve action marker and "imprint" the bolt pattern onto the metal. Where there was only holes to go by, I referenced the holes by measuring the spaceing and location of the holes from a y and x axis, drawing a short line for each measurement. Where the lines crossed at a 90 degree angle, I centered my drill bit. I oversized each hole by around a 1/16th of an inch to allow for any discrepancies. Did not have to redrill any holes.Once drilled, I bolted the mounting tabs on and welded comletely the outside facing edge of the tabs, to ensure accracy. It would allow for some "drawing" out and away from the mounting points on the tractor when I unbolted it. Better "drawing" out than "drawing" in.When I unbolted, I only had maybe a 1/16 of an inch draw which still allows plenty of wiggle room for the bolt holes. I then proceeded to weld the inside edge after dropping the pan. After doing so, all brackets are now square again or unchanged.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:Hey Sparky#1--- There's also another way to do it. (always is)Direct measurement works. What Lugweld did is fine. He was bang on in this case. BUT... you can make some pretty good errors using direct measurement in your layout. There's an inherant error in every measurement, line drawn, and punch mark.For something like this I like to use a transfer punch. There are two kinds of transfer punch. One is a regular punch, and one is a blind punch. The regular punch is for when you have free access to both sides of the hole that you want to copy. You lay your workpiece on a flat surface, lay the mating part on top of it, insert the punch thru the mating piece bolt hole, and give it a whack (just hard enough to make a dimple)The blind punch is for times that either you can't put something thru the hole, because it's a blind hole..........or when you can't take the mating piece and lay it on top of the workpiece (Lugwelds sittuation). You ain't flippin' the tractor on it's side to mark holes The blind punch is inserted in the hole, the workpiece is lined up over the hole with the insert, and you give the workpiece a whack to make the dimple.I'm a nut about not ruining transfer punches. They ain't center punches!! They're one of a kind punches that fit a certain size hole, and it's expensive to buy replacement punches for a particular hole size. They come in sets to fit a wide variety of holes. SAE, or metric. Hit the damn thing just hard enough to make the smallest dimple that you can spot with your eyes. Using machinists blue layout ink can help. Coat the part with the ink, and any scratch/dimple shows up clearly.The beauty of the punch is that we're not fartin' around with lines, X's, etc.... You get the exact center of the hole that you wanna drill. Oversizing the hole is a good idea in order to compensate for distortion when welding.In the OP's case...... I would have inserted the blind hole punch in the bolt hole, then marked the brackets, drilled the brackets, bolted them to the tractor, then tacked the plate to the brackets, lowered the plate, and finished the welds. You can fool around with the surface that meets the plate to make it fit nicely, but at least you know that your're working from a fixed point. Being able to fit the bolts thru the holes is the critical part of the bracket.
