Checked it out, looks like a Avant copycat, but didn't find any dangerous advantages over Avant. Doesn't seem to have FASTER quick coupler. Doesn't have GT cab with heat & AC equivalent. Doesn't have road legal lights/mirrors/registration option. Doesn't have Opticontrol and ASV equivalent. Doesn't have rear 2+1 hydraulics option. Doesn't have rear trailer lights socket option. Doesn't have smooth drive equivalent or option to switch off self levelling. Only 18 kW engine with 180 bar 69 l/min hydraulics. And your website doesn't have proper specifications and options list in english. If you'd make one without DPF but 40+ kW and 200+ Nm torque with 200+ bar 80+ l/min hydraulics and 2000 kp pulling force that goes 25+ km/h in the 2 ton weight range, then maybe I'd consider it.

@@TarqwakN100 can be equipped with all the options you mentioned... and as standard it offers much more than the standard of the Avant 528 -530. btw Avant 528 -530 have the same Kubota engine - same power :)

In 2023 I paid €2750 for this slightly used one, not sure about current price but 2021 list price was €3387+VAT, but the ballpark should be about the same. You could also get a cheap chinesium hydraulic one and make a Avant attachment mount for it, maybe even convert from PTO drive to hydraulic motor. Hydraulic/electric infeed would speed up the chopping quite a bit though.

@@Tarqwak thank you for your reply, yeah I do like idea of using chinesium :D this will help consider my options

The 650i has the hydraulic attachment plate, but at the beginning of video there's 360° attachment rotator already on it that has the manual attachment levers.

Sehe ich auch so !

Il modello MR 160 CDP/4 è un motore idraulico orbitale (tipo gerotor) e non necessita c'è il drenaggio?

It's a good thing that I'm not arborist and I know nothing about how timewasteful this stickchopping is :)

@Tarqwak I am, and I can't believe they even bothered manufacturing this.

@@CivilizedSavage I have a general idea and some parts for making a hydraulic feeder to put between the chute and the chopper, but haven't got around to making it yet. The CH180 model with hydraulic infeed costs like four times as much as this CH100. Even a manual infeed lever contraption would probably speed up the stickchoping considerably.

Haven't actually used the Opticontrol buttons/switch with any tool, but yea it does seem a bit clunky to toggle with rubber boot there. In todo list is to use the Opticontrol for my snowblower, which is doesn't have the FASTER quick coupler but currently with ISO quickcouplers and cigarete lighter plug 12V power line with toggle switch for chute turning.

As far as I know the smooth drive just enables hydraulic accumulator and allows the oil move between boom cylinder rod and piston side. Driving with the digger in front on a bit bumpy asphaIt road at 25 km/h it does make a noticeable difference when it absorbs bounces. Never noticed that before that the 800 series boom topside is completely different and that there's different digger versions for 500-700 series and 800 series, my A35248 or newer A437510 Digger 260 can't be used on 860i, only the RC A443267. When the plate tilt cylinder is fixed by the boom bracket and you lift the boom without enabling the Smooth Drive the plate cylinder pressure is released by overpressure valve somehow, I'm guessing. I did lower the blade one notch so now the blade hits the ground first and then I can adjust the outriggers individually and engage the parking brake. The 650i in the current digging configuration with ~2.7 tons total weight (with driver) it does seem way more stable than the 635 was with ~2.2 tons total (didn't have rear weights). I'm guessing the 860i with RC digger is ~3.5 tons or so. When digging from pavement that you don't want to mess up with blade/outriggers I've used a sturdy plank under the blade, but thought about making a attachment from a blown up truck tyre tread that's screwed onto a plank or some metal contraption that can be attached to the blade. Thanks and looking forward to your 860i & RC shovel videos ;]

I don't remember that it was measured, I'll ask about it next time I'm at the dealer, thanks.

It was just to replace te tank return plug in the quick connector, it was leaking some drops and making a mess, covered under warranty.

Yes it's just a Y-fitting solution, would be nice to have a manual threeway valve there too, but this is good enough already. My 650i was a floor display model and already came with most of the options I wanted, local dealer installed: * Auxiliary hydraulics outlet in the rear, double acting (A449939) * Second auxiliary hydraulics outlet in the front (A449940) * Smooth drive (boom suspension) (A445633) * Engine heater (A449947) * 7-pin trailer socket (A418817) * Road legal registration (TH7) There's more "you can't have" options that a competent dealer can work around, like the Digger 260 with tilt adapter and a thumb at the same time. Or you could have 600 series boom lift cylinder on a 500 series Avant.

@@Tarqwak Interesting. When I ordered my 860i I was told I can get either the front AUX or the rear AUX, so I prioritized the front AUX. So if I order the rear AUX kit and get a Y-fitting I could have both. Maybe the reason it can't be done officially is because there would be constant pressure on the unused coupling? Funny you mention the 260 digger. I have the remote controlled 260 with thumb and was wondering if the tilt couldn't be installed at the same time. Maybe I'll get around to it one day, but then again I don't like the cylinder that sticks out to the side in the Avant solution. Maybe there is a third-party roto tilt adapter which could be put in between. I'd need a secondary remote then. Nice project, but unlikely I'll find the time.

@@Tarqwak A manual 3 way valve would be hard to make the switch accessing in the cockpit. You could get an electric 3-way valve and use one of the empty switch sockets in front of the radio to toggle between front and rear AUX.

Should have gotten the rear AUX from the factory because it's a bit of pain to install later, as I was told ;) I'm thinking the fittings should be able to handle the pressure even when not flowing through, but you could also install a blind plugs in them perhaps. Tried the RC 260 on a demo day, super nice fine thumb control compared to the levered one. I have the regular 260 and tilt adapter, digging trenches there hasn't been a issue of scratching up the tilt cylinder yet, even with a 250 mm bucket. But tiltrotator with a thumb on the rotator body would be nice pick & place machine.

Compared to <1t tracked mini excavator in €6k range the Avant setup is probably more powerful, but compared to 2t class €15k one they should be around the same, Avant+digger would be many times more expensive though. Tracked excavator advantages: * sideshift boom * 360° rotation * better blade Avant advantages: * turf tyres that doesn't maul up the grass * can be registered road legal * versatility, detach the digger and quickattach different tool * hundreds of different attachments: forks (sideshift, 360° tilt), 4-in-1 bucket, leveller, mower, auger, hydraulic breaker, wood chipper, log splitter, snowblower, front/rear 50 mm ball for moving trailers...

For small jobs the 600 series Avants are near perfect, good balance of weight and power. Using the multi function drive unit as a auger driver works best in a sandy soil, if there's big rocks in the ground then the drillbit just spins ontop or gets stuck on the side of the rock. But little help with a metal spiky thing plus some shovel action and you can still get lots of holes done in a day.

Burning ~1 litre of diesel per hour (~10 kWh energy) to get ~1 m³ of wood chips that's ~250 kg and gives ~1000 kWh of heat when burned, I think it's a pretty good tradeoff.

Haven't got the users/operators/workshop manual but there is some various documents available at: maskinisten.net/downloads.php?cat=4 For my machine I drew up some button explanations: docs.google.com/spreadsheets/d/1FUjGNzfdxIHT6HWbY5-0leUJ8Pe5r9YKcCSPTFwTouc

Some of the jerky sideways sloshing is because the quick attach is not very preciesly made on my 260, you can almost fit two M24 washers between the bottom adapter eye and Avant plate. Also side to side there's a quite a bit of slack. Not sure if I had the washers installed on this video, but it definately needs to be tightened up, then side to side motion won't jerk around so much, if at all. Haven't tried with the spikes much, but I did lower the blade a notch or two so that the blade is lower than fully retracted legs are. So then most of the time the blade should dig in also. Also on this video I think I forgot to put on the parking brake, that's why the tyres are rotating. They should do a demoday with moist clay, that'll be frustratingly (not) fun -.- In Estonia the local dealer is also building a new ~2000 m² showroom/office.

I'll try to do a video about it, but basically you undo two nuts under the lower piece of the glass and lift it out, then attach the digger to the quick coupler, secure it to the boom with a pin manually, attach the hydraulics and carefully shimmy the digger control levers through the window opening. And you'll have to be very careful not to pinch the levers against the upper window edge when booming in/out and/or lifting the boom. It would be great if the window could be lifted up in one piece under the roof like on excavators, but it's not designed to do so, and with GT cab I'm not sure there would be enough headroom for it, but I'll try to model it up oneday, maybe it's doable.

Why not both?

I'm not sure the single shank ripper on 210/260 would do much better than a 250 mm wide bucket, as the cylinders are quite small and they don't put out quite enough force for the heavy duty ripper action. Better would probably be to have the ripper direct attached to Avant coupler. I'll do a 260 push/pull force measurement video oneday... I have the multimode machine "Stahlwerk WIG TIG AC/DC 200 + Plasma S" from around 2013. The plasma part works fine but not ideal for 10+ mm plates. Ideally should get a separate 5+ kW threephase compressor but for this kind of small cuts even my ~1 kW with 24 litre tank worked fine. On the plasmacut/compressor clips I tuned down the audio -12 dB, so it was actually 4 times louder or so. The pins I left with just the tackwelds, they're not going anywhere even with those and easier to remove once the need arises, probably never though.

I agree that Avant itself would have more power if a ripper was made for the normal work device fitting. It has much larger cylinders than those excavator devices. The problem I have had is that Avant has to be moved more if a ripper is directly in Avant. With the excavators it usually doesn’t need so much to drive around though it takes time. Thinking of a wet and soft ground and tractor type tires I have. I have 400 and 250 mm buckets and a special prototype ditch bucket for the excavator. The ditch bucket is a proto and Avant didn’t give any warranty and I use it on my own risk in the excavator. They made several years ago some of those and I bought it last year when they emptied their storages. The ditch bucket is actually better for stumps than 250 mm bucket. It is maybe 200 mm on the bottom and 600 mm on the top. It is taller then either of the normal buckets and it has very sharp sides. It also empties better than those other buckets because of the shape. I have quite a lot of clay here and especially the 250 mm bucket fills up with clay and it won’t empty itself, maybe 2/3 is filled all the time when digging clay. I’ve dug up stumps using all three buckets. The largest stumps have been of about 35 cm diameter pine and birch. Both fresh stumps. Took for awhile. The excavator couldn’t lift those. I had to roll them on the ground. I think 210 exc. has 50/25 cylinders. 50 being the inner diameter of cylinder (piston) and 25 being the diameter of the rod both in mm. Not sure though. I’ve been thinking if it was possible to switch the bucket cylinder and the boom cylinder (closest to Avant) to 60/30 if there was enough space. 210 is much smaller and lighter than 260 (about 230 kg only vs 420 kg or something). So it might not be able to handle the bigger cylinders.

Just did some digging in moist clay/peat/gravel mix of materials and yup the 250 mm bucket gets clogged up in ja jiffie -.- Measured the 260 digger cylinders, rod/barrel outside: Boom 32/73 mm Arm 36/73 mm Bucket 36/73 mm Turning 30/70 mm Tilt 25/50 mm Guessing the barrels have 5 mm wall thickness, then at 200 bar they apply push/pull force of: Boom 6.4/4.7 tons Arm 6.4/4.3 tons Bucket 6.4/4.3 tons Turning 5.8/4.3 tons Tilt 2.6/1.6 tons Based on: www.trelleborg.com/en/seals/resources/design-support-and-engineering-tools/hydraulic-system-calculator SolidWorks or some other similar software could be used to find out the structural load limit based on the boom material design and thicknes. Compared to the 635 that weighed ~1.6 tons and had only one 36 kg rear weight, the 650i with 180 kg rear side weights and 36 kg rear weight (total ~2.2 tons with driver + ~0.5 tons the 260 digger) is now much more stable for digging, blade and outriggers down, parking brake on and it hardly ever moves forward due to digger pulling it.

I just hate how KZbin comment field works with iPad. Have to retype … ----- Your 260 is more powerful clearly. I googled this because I jave not registered on the Finnish Avant site to download documents. I have the needed docs on paper. shop.avant-lader.ch/out/media/Backhoe%20260-3%20a37510%20&%20a433851%202020-06-10%2009-27-07.pdf That link has the PDF of parts list of 260. The document is published in June 2020. The boom seems to be D63/32 and the arm is D63/36. The bucket is D63/36. You got the wall thickness correct. My Avant is about 1,6 tons with the driver. 210 is about 230 kg. 210 digger can’t move my Avant, but it can easily lift the front wheels up in the air if the bucket is moving downwards. Well, digging a hole in the ground. 520 model has maximum work pressure of 185 bar. Having smaller cylinders and less pressure 210 digger on 520 Avant is clearly weaker on what comes to the cylinders. I checked on trelleborg site the boom cylinder lifting force and it is only about 2,8 tons. That is the worst because it is a pulling movement. Pushing force was about 3,7 tons. But those are only the values of the cylinders. The measurements and the geometries of the whole backhoe should be considered. It depends a lot of how the triangulars are in the backhoe. I mean if the cylinder can pull with 2,8 tons how much that is in the bucket when the backhoe is reaching out the maximum. How the boom cylinder is lined with the structure of the boom. I have to do some measuring later if larger cylinders would fit …

Fully RC Avant? That would be cool! On Avant demoday I got to try out the RC excavator attachment, way smoother contollable with thumb joysticks, and it also has rabbit/turtle speed selector, was buttery smooth. Costs like €11k+tax though -.-

I think he talked about RC controlled 260 backhoe.

Avant 650i is new, all the other stuff has been hoarded over many years.

It's ~185 hours used, asking price was €45k+VAT, as new this configuration would probably be €58k+VAT range just for the 760i, the 4-in-1 bucket is ~€2.8k+VAT.

The coldstart issue is with the Kubota V1505-E4B Stage V motor (4-cylinder, 19 kW, 2500 rpm max, 50 l/min hydraulic oil flow), allegedly it has different camshaft compared to the older Kubota V1505 Stage 3A (4-cylinder, 28 kW, 3200 rpm max, 66 l/min) that didn't have much coldstart issues. Current Avant 635i/640i models have Kohler KSD 1403NA (3-cylinder, 19 kW, 3000 rpm max, 66 l/min) motor, I'm not sure if this one has any coldstart issues. There's also Avant 645i/650i with Kubota V1505 CR-T (turbo, 4-cylinder, 33 kW, 3200 rpm max, 75 l/min) motor - but compared to the older ones it's said to have only air intake grid heater, no glow plugs. With the 635/640 19 kW Kubota, if you can run block heater for ~15 min and have hot air intake then the startup isn't a big issue. www.avanttecno.com/global/machines/600-series

Yes, with a 1400 W hot air blower.

Kui juba käima saab, siis toimib muretult. Soojalt restart ka poolest pöördest. Nüüdseks plokisoendus ka lisatud, ~15 min eelsoendust ja läheb ühe/kahe eelsüüteküünlatsükliga. Kuuma õhu sissepuhkega veel paremini muidugi.

Kas jätad oma kontakti ka et saaks käivitust arutada voi helistad ise?

Yes, dangerously slow acceleration and moderately slower breaking (the trailer has intertial brakes), other than that no issues as it was nicely balanced and I didn't go over 70 km/h.

Try doing it faster with a shovel and a pickaxe ;]

True that =)

The MT8 takes ~1 litre of diesel per hour, and it takes about an hour to make a 1 m3 (~250 kg) of woodchips by myself or only ~30 minutes with helper.

@@Tarqwak okey i am sorry just seemed to me like it wasnt that fast 👍

@@Tarqwak its a nice tractor how many horsepower? Do you know?

It has 24 kW Lombardini LDW 1503 three cylinder naturally aspirated diesel engine, so about 32 HP.

@@Tarqwak seems like the perfect tractor around the farm or homestead 👍

its no Avant trailer its a LT300Timber trailer no official Avant Brand

@@john23-q9c AVANT made one, about 10 years ago. It actually ties into the AVANT Hydraulics, has controls from the cab, and is pulled from the back. Thanks though

This is a Chinese made timber trailer, ~2016 model year. In theory 3 ton cargo capacity and the crane should be able to lift ~300 kg at max distance of ~3.9 meters. I've added the ISO quick couplers to use it from Avant auxilary hydraulics but this time I forgot to bring the hoses and had to use the onboard pump with gasoline engine.

@@Tarqwak Thank you!
