    Yamaha UMAX: blurring the line between UTVs and golf carts

    A bunch of these have landed in the 'hood here. 2020 Yamaha UMAX. 48V SLA battery-powered, 2WD with differential and dumpable cargo box. Super-quiet. Anyone have one of these? The new ones offer lithium batteries, but at a 50% premium.

    re-sealing some old Kubota B8200 FEL cylinders

    I agreed to fix the leaks on a friend's old 80s era Kubota B8200. This tractor is common around here, and the way the cylinder goes together is just about my least favorite. The end cap (gland) uses a springy wire that is captured by a groove inside the lip of the cylinder barrel. I have done...

    Toro Workman 3200 project...anyone have one of these?

    I got one of these recently. Price was right (free, delivered). It has a transmission problem that I plan to fix. Anyone have one of these? Not much on Utube. This one is 2wd, with diff-lock, 3-cylinder Mitsubishi gasoline-powered 4-stroke, with hydraulic dump. Trans is a synchronized...

    fabricating a new and improved bucket for my mini-excavator

    I recently imported a new mini-X from China, and it has been very useful. The buckets that came with it, however, leave a lot to be desired. They are too flimsy, too shallow, and use soft cast steel teeth. This will be the 2nd bucket I have made from scratch, since I made one for my...

    New Branson 2610h just arrived. Initial impressions.

    Last fall, I went looking for a CUT with HST for my neighbor. Something fairly new and low hours in the 2000-3000 pound weight class (naked) with loader. Slim pickens in the local used market. So I got a quotation from the Branson dealer 100 miles from here, and got a price for a 2610h with...

    Backhoe Kubota B20 with BT750 backhoe: Auto Return feature

    Recently got another tractor project, a 30 year old Kubota B20 TLB. Neglected, and needing lots of minor repairs. Question: has anyone who has owned, used, and/or worked the integrated backhoe, BT650 or BT750 know much about the Auto Return feature? It seems Kubota gave up on this function...

    Chinese mini-X track came what?

    Well, I have been using my Chinese excavator, and I now have almost 30 hours on it. For those who have not seen my earlier thread on how I got it, it is a 1-ton unit called an XN08, made by Xiniu, aka Shandong Landworld Machinery. I knew it would happen eventually: I threw a track. By that I...

    making an hydraulic thumb for my new mini-excavator

    I recently imported a new 1-ton mini-X from China, and it needs an hydraulic thumb. It came with a mechanical thumb installed, but it is flimsy and won't do at all. I made an hydraulic thumb for my backhoe years ago, and it is indispensable. So, over the next several days, I will post pix and...

    Help me identify the make/model of this compact 4x4 tractor

    Can anyone identify this tractor? It looks to me like a grey market Japanese CUT, given what looks like rice paddy rear tires. The FEL looks home-built. The 'S' logo makes me think of Satoh or Shibaura, but I have not found any logos like that yet. I only have these pix to go by. I do not...

    Importing and modifying a new mini excavator from China

    It has been a while since I posted a Big Project on TBN, so here we go again. I have been on a quest for a mini-X, so I imported a new one from China. It has been complicated and took a lot of time and energy, but it is here and working. Over the next week or so, I will post about my search...

    Anyone buy from Fast Lane Equipment in Kemp, TX?

    Kemp, TX is halfway between Dallas and Tyler, TX. They have a mini excavator I want, if I can figure out shipping. Of course, I would have to pay an inspector first, and pay for the unit in advance.

    backhoe repairs: how to get those pesky sleeve bearings out

    My backhoe attachment now has maybe 200 hours on it and I need to do some repairs. My hoe is a clone of the Woods 7500 unit, but somewhat beefed up, and made in Bulgaria. It has served me well....trenching, excavating my mountain trails, and moving tons of rocks and logs. I have damaged my...

    new Kioti CK4010H at the World Ag Expo

    Just got back from the World Ag Expo in Tulare, CA. 75F and sunny, but the usual horrible stench of cattle effluent. Anyway, here is the new Kioti. As usual, no one was there who know the fun technical details. The brochure seems to indicate the engine is 39.6hp, gross, but has the same...

    Anyone replaced the seals on their CK25/27/30/35 implement/PS hydraulic pump?

    I was helping out the owner of one of the 2 CK30s I bought back in in 05. Seems he had another pump failure...the 2nd one! The first one was maybe 5 y ago, and the pump was replaced back then. It seems that Kioti replaced the original Casappa, made in Italy, with a Joyang, made in Korea...

    my latest project tractor: a 2003 McCormick GX50H

    Well, it's been a long time since I had a broken tractor to fix, and now I have a new one. This is a 50hp hydrostatic tractor, made by Landini in Italy, a GX50H. It uses a 4-cylinder Yanmar Diesel, and features a compact size (only slightly longer than my CK30) with 4x4 and lockable front AND...

    when is a "hydraulic cylinder" a "ram"?

    Well, some would say, never. And terminology does matter. I am prompted to write this after getting one of those emails from our hydraulics guru from Down Under, Bendan Casey. In it, he equates a "ram" to a "displacement cylinder", or a cylinder without a piston seal. Some folks call any...

    a homemade utility vehicle with hydraulic dump

    Well, not completely homemade; I started with a Suzuki Samurai. Moving dirt around with your tractor, one loader bite at a time can be pretty inefficient and frustrating, esp when you need to move the dirt more than 100 feet or so. 500 feet, and you REALLY want a dumptruck. So.....I have...

    Kioti parking brake failure...has this happened to you?

    Last week, I noticed that my parking brake would no longer stay in one of the 2 positions I use. The more-on position, which I use on slopes, was kaput. The other position, which I use on level ground (not that I have much) still worked. Anyway, the PB is very important, so I popped off the...

    powering a hydraulic chainsaw off your tractor's hydraulic system

    ....or..."Hydraulic Chainsaws for Fun and Profit" A long time ago, I fantasized about building a boom-mounted chainsaw to connect to my loader. This would allow me to trim branches off trees from the seat of my tractor. The loader can already reach more than 8 feet high, and the boom I...

    Well, I recently finished another backhoe subframe. This may be my seventh or eighth? I lost count. This is for a 2001 John Deere 4300, and a new Prairie Dog 7.5, a Woods 7500 clone. I recently rebuilt this former rental tractor; the thread is here...

    fixing a bent Bobcat 4-in-1 loader bucket

    I was taking some engines to the metal recycler last summer, and I decided to stop at the Sales side of the business to see what they had. It never ceases to amaze me what folks throw out, and this day was no exception. I found this 60-inch Bobcat QA 4-in-1 loader bucket, with a somewhat bent...

    eBay/Craigslist TC35 HST broken tractor for sale: $6500

    A tractor recently came up for sale at a dealer in N. CA. It's a 2001 with HST, 4x4, and loader. The MFWD is broken, but the engine runs and the tractor moves in 2WD. I have been looking for a few years for just this kind of project, an HST NH CUT needing repair. I want to dissect a blue...

    Tiller Does everyone use shear bolt or slip clutch drive shafts with their rototillers?

    I am fixing up some JD 550 3-point rototillers and I need to buy new drive shafts. I notice that lots of units out there do not use shear bolt or slip clutch protection. I don't do any rototilling with my tractor. Those who do: do you use protection? If not, what happens when you pinch rocks?

    Tractor News Interesting Shibaura engine plate on new T1530

    I saw this plate on a new economy compact at the New Holland exhibit at the recent WorldAgExpo. It's a Shibaura 2.2 engine on a T1530. It says it is compliant with the newest CARB standards for off-road Diesels for 2010. For 7 years or 5000 hours anyway. I wonder what happens then..... NH...

    annular cutters: a better way to drill big holes in thick steel

    For you non-professional steel fabricators out there, here is the latest method I use for drilling holes between 1/2" and 1 1/16" in steel plate, up to 5/8" thick. A lot has been written on TBN over the years about holes, but this is a surprisingly economical way to go. I expected to see more...

    adding hydraulic tilt to a 4-in-1 bucket

    Years ago, I helped to install a 4-in-1 bucket on a Kubota L2550DT. This is a Construction Attachments unit, and it is HEAVY. It easily eats up half of the lifting capacity of the BF400G loader. When I tried it out, I was less than enthusiastic about 4-in-1s on these older tractors. I have...

    page(s) missing from my Kioti CK30 shop manual

    System hyd pressure relief valve for CK30

    why you have to check those hyd pressures on a new tractor

    Just got another new tractor. As is my habit with any piece of equipment I get, I thoroughly checked it out. I found one FEL bolt that was barely started and a hydraulic pressure test that showed 3000psi at the loader! This means that either the FEL relief valve is at 3000 and the system RV...
