Hello, I was curious if anyone could help me find a repair manual or give me some instructions on how hard it is to fix a leak in my hydraulic system on my Kubota B7100 HST Diesel. The leak appears to be coming from the actual controls itself. I also noticed that there is a drip that looks like...

Hi. I posted this in the Kubota owning/operating section but it might be better suited for this forum - I’m putting a 304 loader on a B7100. The LA304 loader is rated for 4.4 GPM@2000psi. The hydraulic pump on the B7100 is 3 GPM and supposedly somewhere between 1500 and 1700 PSI. I only plan...

Hi folks, This may have been covered elsewhere so forgive me if so, but I want to share an experiment I am doing. I have had trouble with my 1980's B7100 HST overheating when I'm cutting heavy, deep grass with my belly mower (deep as in mowing a grown up field). With only the thermosiphon to...

The three point hitch on my B7100 will not "feather" when raising. As I start to raise the lift handle, it makes an awful noise (like a dead-end hydraulic circuit) until I pull it to the full up position where it then raises normally (but at full speed) . this is not a big issue for mowers /...

I ran out of fuel in my kubota not the first time. I have successfully bled it several times over the years. After that I couldn't get the tractor to run solid. I thought I must have filled with bad fuel. I changed out the fuel filter. and have bled for days. I cant ever get the motor to...

I just picked up a 1980 B7100, and am starting to go through it. When I bought it, it was known to have oil in the coolant (or something turning it black). I've noticed quite a bit of smoke coming out of the valve cover vent hose when it's running (no oil coming out, and it's not moisture), and...

Hey guys. Discovered a small leak in my recently purchased B7100's radiator. The fins are pretty beat in several spots, and I figure it should probably just be replaced. Called a local kubota shop and they want over $400 for a replacement! No big deal, and I'm not in a huge rush to replace it...

I've been keeping an eye on these for a year or so and price is probably in line with others. I think I've seen the tractors alone for 3000-3500 but this one may be in nicer shape, and if you have to buy a new loader they can cost around 2000 is what I read. He said he could go 5000 for the...

As I was researching my first tractor, I just found out there's a 1990s Kubota B7100 HST 4x4 already in the family that I can probably have for free. It's in decent condition, but sadly it doesn't have a FEL. I've read that a FEL might be asking too much of this tractor anyway? I can see that...

Was just curious as to how much it would cost to go through and rebuild a 1981 kubota b7100dt both engine and transmission wise. The tractor does not need a rebuild but just wanted to see if any of those users who had rebuilt their b7100 remembered or could point me in a price scale once all the...

I just got a 1984 B7100 HST. It has a left foot pedal for clutch. What is the purpose of this pedal ? HST is just push pedal fwd & Rev. Also, HST is a bit noisy. Not a grind or metal on metal noise, more like a buzzing sound. Maybe just the sounds of hydraulics or a hydraulic pump when I push...

Saturday a man told me he'd sell me his storage building and his B7100 and priced them to me. I said I'd pay his price if he got the B7100 running and moving under it's own power. He has left it sitting out side for the past year and a half and only drove it a couple of times. Today he (he lives...

I have a B7100 with scraper blade and 6 foot trencher. The tractor runs fine, but has a hydraulic leak. Wondering if this thing is with anything or should be scrapped.

I recently bought an older Kubota B7100HST-E (2 wheel drive) with the serial number in the older set of numbers. When I put a 40 inch category 1 bush hog on it and started clearing my lot, I hit a stump and sheared the splines from the HST shaft going toward the clutch. On the Kubota parts web...

Hey Guys, My B7100 fires up and gets to idle just as expected, but as soon as I put it under much of a load (even such as climbing a hill), it acts like it's too much. It starts to bog down and billow black exhaust. Take the load off, and it idles right back up. On flat land, it drives around...

Just picked up a B7100 with a little over 900 hours and in decent shape. I spent several hours doing routine maintainence but decided to remove the radiator which was full of debris and cleaned/straightened the fins. It appears the radiator screen is a poor design to start with but the previous...

steering design not heavy enough will any other steering box bolt up

Hi, all! Just bought my first tractor for my hobby farm in Oregon, and haven't even taken delivery yet. My on-scene expert tells me that the Kubota B7100HST creeps forward very, very slowly when neither the forward nor reverse pedal is pushed. I'm not terribly concerned about this, and I...

Guys/Gals I hope someone can help I have an old Kubota B7100 4 wd which is an absolute work horse for me on my small holding, the trouble is a noise has appeared in recent months. The noise sounds like a 'graunching' - when you engage gear and release the clutch to pull away in any gear the...

Hello, I have a chance to buy an "old type" (serial number less than N60163) Kubota B7100 HST. It is a 4wd tractor with good tires, and the seller doesn't know the year it was manufactured, but it has more than 3000 hours on it. This seems like a LOT of hours for one of these little tractors...

I have owned this 1984ish b7100hst for about 3yrs. I have never been concerned with the charging system, the PO said it does not work. I never used and lights, and it always started good. Now I am doing a power steering add on kit. I decided to go with a pump driven by the belt. I thought...

HELP! I've owned my Kubota for 5 years and suddenly lost the front wheel drive while plowing snow. First time after years of farm work with my baby. I removed the front differential cover's 3 bolts and found the pin that holds the U bolt to the front differential sprocket was sheered off. Upon...

Just bought a B7100 with 2000 hrs. Runs great but would like recommendations on what oils to use for engine, case oil, gear oil. Standing by, thanks much.

Can anyone tell me what the auxilary hydraulic capacity is when connecting to the manifold block? What is the gpm on the pump and the pressure relief valve set at? I am wondering if it would run a small log splitter or has anyone tried this. The log splitter has a directional control valve...

How do you check to see that a stator/dynamo is working properly? The machine I just picked up had the wires unplugged from the harness and I think that it may have been unplugged for a reason. I do not want to get into cleaning and repairing only to have to go back and replace the unit...

I've checked the fuses, emergency lights work, the tractor starts, but I can't figure out what to do about the hour meter, headlights and horn. Ideas?

I recently bought a well used B7100 (70's) and after removing it from the collapsed barn it was in and got it home, I spent hours reading on this site about how to fix the steering box. It was apart when I got it with bad top and bottom bearings. Without too much trouble I got it back together...

Hi guys: I aquired an old Kubota B7100, that has been sadly neglected. It has a tiller mounted, but the bearing where the shaft enters the housing on the right side has dissintegrated. Got the shaft out, but it's badly messed up inside. There appears to be the inner races of 2 bearings on the...

I have a Kubota B7100HST I will be selling and have no idea of what is a fair price to ask for it. I have owned it from brand new and it has just shy of 1200 hours. Maintenance has been done on schedule and I have never had a problem with the tractor. It has always been parked in the garage and...

I have an old (1979) B7100HST that has run beautifully for 30 some years, but over the past two years, the transmission has been increasingly hesitant, at first being slow to respond when I depressed the forward or backward foot pedal, then taking up to 20 seconds to kick in for about 6 months...

Can anyone tell me what thread size the hydraulic port, with the handle, under the seat is? I'm assuming it's metric? It leaks when the revs are high, so I'd like to get a plug for it until I can fix the valve when I overhaul it in the winter. Thanks, Jim

Hello friends! So some how while moving compost I managed to lose three of the 4 bolts holding my front left wheel on to my tactor. I've swept the entire path I traveled with a field magnet but I cannot find either of them. The single bolt left has printed on the top "Lobo 8.8". Does anyone...

I am new to the tractor world and got my hands on a Kubota B7100D. The tractors in good shape and runs great. The question I have is about the trencher on the back. After looking at it, it looks like most of the 3 point was removed to get it on there. Any idea what parts I would need to be...

The story I got was that it was jumping out of gear under load but don't know if they meant the trans. or the PTO. Got about...

Hello, I am looking at buying the Kubota B7100HSD. I just bought 7 acres of land that's kind of hilly and was wondering if the hydrostatic transmission on these tractors hold up well running on slopes. I have used small lawn tractors with a H/T in them and they seem to wear out fast if you use...

First what a great forum!! I have read every thread (i think) on the steering box failures. Now after reading I have a few questions. 1. what exactly is sleaving? and can I do that or do I have to go to a machine shop? 2. I read where someone used b6100 assembly but I was wondering if I will...

So i'm headed off to look at a used B7100 w/1700 hrs on it tomorrow. No FEL (unfortunately) but comes with snow plow, swisher 44 tow behind mower, and garden plow. i dont know the year but i would make a guess by looking at the picture i saw that its mid 80's vintage. this is my first...

I have a '94 B7100HST that is new to me. It had a problem where it would not return to neutral. The opposite pedal had to be tapped to get it stop travel in that direction. Annoying to say the least, dangerous an understatement. examination from underneath identified the problem, which...

Bought the B7100HST about 2 years ago. Use it to mow a bit over 1 acre yard with a 60" deck, and have a 50-52" tiller that gets quite a bit of use. Been half heartedly looking for a replacement, the 7100 has a few issues, and would like to upgrade to something with more creature comforts...

I Have decided to put chains on the front of my B7100. I've gone back in the archives and reviewed all I could find. For my tractor, size of tires and budget I think they will work fine. So when looking for the size on my old and worn turfs, barely legible, I think I found 20.9 X 8.0 - 10 as a...

I have a buddy who has a Kubota B7100, 4wd, fel, runs great but the hydraulics are in slooow motion, what are some of the things we can check, thanks for any help.

I'm not mechanical. Its a real drawback in the world of tractors but this is the fact. So when my FEL started to stagger and shake and become unresponsive to the point that i couldn't get it into the barn without putting some ramps under the front wheels I called by buddy Farmer Dave as he knows...

Hi, all My "fix" broke after only 6 months Sure could use some expert advice I replaced the rubber cover, brass ring assembly and cleaned up everything last time and thought that would be the end of it for several years. NOT! This time the metal cover pipe broke at the rubber cover behind...

I recently aquired a 1977 Kubota B7100. I have a drag blade and am waiting on delivery of an after market loader. Does anyone have a line on parts and empliments that fit or can be modified to fit the B7100? :tractor:

I have a B7100 that leaks antifreeze under pressure only ( during mowing) . It looked like it was coming from the bottom of the radiator. I have taken the radiator off and drained the system. I am going to have it pressure tested. If the leak is still there after I ensure the radiator is good...

Hi I have an older B7100HST. I was wondering what each bolt was for on the attached pictures. Is bolt #1 on the axle used for checking the level and filling? What are #2 and #3 used for. Does bolt #1 fill the entire case? Should I be able to see the oil level inside. How much fluid does entire...

Well after a winter cleaning, re-ringing, and honing, it's time for the ol' d750a to go back together. Just a few questions. It'd be convenient if someone knew the answers, although I know they're all probably in the service manual. A bit of laziness on my part I guess. Are there any cues for...

I have a B7100HST and the input shaft that goes into the HST unit has the splines sheared off. There is a coupling that goes on this shaft and a pin that holds the coupling from sliding forward/back. At first examination it would appear that this is a shear pin, but there wouldn't be splines...

my B7100 reverse pedal works fine but it won't work going forward. The rocker pedal simply bottoms ( no tension in it at all, ) out w/ o any action on the part of the tractor. I've tried adjusting the spring, that didn't help. Need suggestions please

I have two B7100 HST (one old model one new) and behind the fan is what appears to be a water pump on the old one which is frozen and needs replacing. This is stopping the fan from turning and the belt just slipps on the pully. according to some posts i have read,the B7100 does not have a...

I'm reassembling my Kubota b7100 Engine after a re-ring and valve hone, and I'm just wondering if I can use new heavy duty diesel oil for all parts such as valves, valve springs, rocker assembly, etc. Is any other sort of lubrication required? This may seem like a silly question, but I don't...

Hi, New to this forum and thanks to all who provide help here. I noticed that I am losing ever so slightly coolant from behind the thermostat housing between the gasket/flange and head. It's just seeping but is causing scale and popping the paint. Looks to me like the gasket needs sealer or...

My RC60 belly mower rusted out. Looking for a new or used one. Would consider a 54" if available.

Hi, I am seeing numerous B7100 (some HST) that say the HP is 20. But according to tractordata, it's 16. Is there a 20HP b7100 out there? Or are these sellers just misinformed?

Hi, I'm a brand new member and haven't learned all the forum functions. My question is that my dynamo on my Kubota B7100D wore out and has metal chips in it. I bought a replacement one, but now that i have the old one off i have noticed that they are different. Everything is exactly the same...

Hi guys Looking for some help regarding the function / operation of the drive shaft cover. Take a look at the picture item#10 is a metal pipe that covers the shaft held in place by a rubber boot item #20. I heard strange noises and took a look see The rubber boot was destroyed, the oil seal...

Looked at a little B7100 4x4 today showing under 400 hours on the clock. No deck. There is a BEEFY subframe attached to a very large hydraulic plow with up/down and side/side cylinders. The plow itself is a Bolens and looks like it was welded to a Kubota subframe that's quite beefy. The guy...

Just bought this B7100 over the weekend and was moving some dirt around the yard with the loader while the backhoe was on the 3pt. I started noticing some intermitent noise coming from the rearend. It almost sounds like the lugs on the rear wheels are loose, but when I shake the tractor side...

I have found one of these w/ 1100 hours. It is 4x4 w/ a Kubota FEL, 4 ft Befco PTO tiller and a Kubota 3pt backhoe (not sure of the model). I drove to look at it tonight and had a chance to run the tractor, loader and hoe. I actually like the whole set up. The hoe is a little big for this...

I was using my B7100 HST this afternoon and suddenly the forward and reverse pedal will not go to reverse. There is plenty of play in forward but none in reverse. I am new to this forum and would like any help I can get.

I'd like to run front chains on my B7100 with turf tires. The reason I have not up to this point is that there is a very tight clearance between the tire and the steering knuckle. I'm concerned that if the chain came off or was loose, it could catch the knuckle and cause come expensive damage...

I'm looking for some experienced b7100 owners here to perhaps give me a little advice. This winter I'm doing a rebuild of my b7100's engine (blowing lots of oil at idle and lots of blowby at any time when running)...and I'm wondering how to get the engine out. I've heard it's neccessary to...

I'm in the process of removing my crakshaft in my B7100HSD with the D750-A engine because someone before me had let the throwout bearing problem linger and thereby also wiping out the pilot bushing in the crankshaft. I ordered the WSM service manual and just received it and to my surprise it...
