Some updates on the Kverneland plow has been made in the weekend. As you can see the moldboards are attached to the 'arms'. The 'front plows' are only temporary, they are glued on just for pics. New ones will be bolted on. Still need to make the depth wheel, stand etc. Paint and decals. Here is some pictures for you:

That is a very nice model. I like all the details you put on your models! Actually I was thinking about making the exact same model in scale 1/16. Keep up the great work! Anders

Raw footage, no edit on these 3 videos. First is my tractor that some may already know. It pulls a 6row John Deere corn planter and a Rabe stubble cultivator. The third video contains a homemade tractor. A CASE 4994 in scale 1/10. -NOT mine. This is a heavy weight tractor with all functions! I cant' remember the exact weight, but it's around 15kilo / 33 pounds! It features - a hydraulic system that provides 10 bars of preassure to the rearhitch and output for impl. - Frontwheel steere, all wheels steere and crab steere. - Lights - All wheels drive, all wheel drive with diff lock. - 3 speed Everything is homemade, down to the 3 speed gearbox. The plow and stubble cultivator is also homemade. Approx 8-9 pounds each. http://www.youtube.com/watch?v=-bRPTIwfPKA

Hello, here is the start of my new project for my radio controlled John Deere 7920 tractor scale 1/16th. It's a Kverneland LM plow, 5 furrow, reversible. Kverneland LM For now everything is made out of brass, but some plastic parts will be mounted before it's finished. The moldboards will be plastic, but the 'arms' will be aluminum. The weight is now 1 pound. The weight is good I think as it will automaticly dig into the soil. I'll work on the landwheel later this week. It will flip over and still be able to hold up the plow to the prefered depth... For now the main frame and head is almost done, backpanel and hydraulic cylinder on the head and some minor changes to the mainframe is missing .... more to come....:

Thank you all for your comments! Well, this was my first attempt filming with my new DV camera. More movies to come soon, corn planting, seeding, mulch ripping, cultivating -and plowing! Thanks again! Anders Kolpen

Click the link - the motor sound is from some trucks and battletanks in the background. Not the tractor. Thanks for watching! /Anders Kolpen

Can anybody please translate what Ricky just said into english? I did'nt understand it...... Thanks for the comments guys! /Anders

Hello everybody. I completed the frontlift last week. I had to make the stabilizer in brass to handle the torque from the lift servomotor. I installed a digital servo motor to raise and lower the arms. Also that type of servo is installed to the rearhitch and the steering. With a digital servo you can program the speed. I wanted that feature to give a realistic touch to the model, as the servo will travel slower than usual to look like oilpressured cylinders. ----------------------------------------------------------------------------- The rearhitch is somehow 'redesigned'. I wanted the same 'claws' as the frontlift so I had to make new liftarms. You will also notice that the rearhitch is adjustable by the leveling threads in each side. Sometimes I wanted the implement raised a little in one side to make it level, but couldn't do anything about it. That is history. Also all plastic parts on the tractor is painted. Ladder, rearhitchparts etc. (Not fenders, hood and roof) Now I can start working on the implements to go in front and behind. I will attend a danish modeltractor show, where I will be demonstrating a redesigned (Bruder) LEMKEN 3m Smaragd disc cultivator. Working in wet sand. This soil gives a realistic wiev on how the soil is ripped up. A video will be made at the show. I also want to start with an Accord/Kverneland Tine Seeder 3m or 4m with frontmounted seed hopper/wheelpress. http://www.kvernelandgroup.com/irj/portal/anonymous?NavigationTarget=ROLES://portal_content/KVG/com.kverneland.www/www.group.roles/KVG.com.kverneland.www.www.group.roles.guest/KVG.com.kverneland.www.com.kverneland.pages.corporate_enduser_bpfwe&navChange=/Intranet/Internet/ien/Brands_Products/Accord/Accord%20Products/Seed%20Drill%20Combinations/Accord%20TS.doc Hope you all enjoyed Anders Kolpen Denmark

Well, almost... Today I made the last parts for the frontlift. (Opico / HeVa) As you will see from the pictures it will raise and lower by a servo motor. I still need the servo, that will be picked up tommorow (I hope). It will be a digital servo that will be programmed to operate as slow as possible to give a realistic movement. I tried to 'mount' it all today and tested the functions with a regular servo motor. It performs very well and I expect that it will lift at least 1 pound. More than enough for a frontmounted blade, seedbox or extra frontweight (battery). The parts are made as the original. Each arm can be 'parked' backwards by removing a pin and bolt. I am very satisfied with the result so far. I had to make a new stabilizer bar in brass instead of plastic, because I realized how much torque the servo brings. You will be able to see, basicly, how the lift will be operated by the servo. There is still some touchup to do, like the liftarms etc. to be more realistic.

Nice tractor http://www.troisiemepoint.net/article.php?num=1346 (not mine) found it browsing around.... /anders

Not mine, found it while browsing around...... Link: http://www.troisiemepoint.net/article.php?num=548 Probably seen before, but worth another look!!! /anders

The hitch-frame is now mounted. Sideplates, top, stabilizer bar and mounts are ready. It is now totally alligned with tractor and everything sit perfect. As this is not just a model, but also a working vehicle, it needs to be made solid. I said before that the styrene material was a bit flexy, but okay for the time. As time has gone and I following the instructions from the drawings, the reinforced parts has made the whole thing VERY solid and stable. The 'bolts' is from a BRUDER Joskin trailer's wheelhubs Now I need to make the cylinders, liftarms and the servo to raise and lower. MORE TO COME Here is a short videoclip from the manufactures website; http://www.he-va.com/index.php?page=4&id=29&video=67 More news to the tractor. I installed a German precision motor in the tractor called Faulhaber. The god thing about this motor is: No noise Low RPM Extreme torque Low current cosumption My gearbox went down from 208:1 to 124:1 to deal with the lower RPM motor. Still it is able to pull much more than the previous regular motor. Really a smooth and quiet ride now :wink: Right now I use one digital servo for my rear 3 pt. hitch. The future (next 14 days) is to install two digital servos for the fronthitch and the steering. Thing is, that with a digtal servo I am able to program the speed and a lot of other thing from a computer. Slowing the speed to a minimum makes the tractor perform more realistic, like 'oil pressure' if you know what I mean. The high speed standart is a big problem for todays trucks, tractors etc. But good for aeroplanes and fast cars. Enjoy the pics. /Anders

@mjb1 Thank you very much! @Tracterror The rear diff from these cars should work too. Problem is, if I remember correct that they don't have a solid axle for the output. Nothing that can't be fixed though! Have you ever considered using a servo for drive motor? Instead of the SIKU contr. unit? For a forage harvester you would probably have the space to fit regular eletronics like, batterypack, receiver, servos etc. see this link for hacking a servo to be proportional in both direction, 360degr., with built in speed controller. http://66.249.93.104/translate_c?hl=en&u=http://www.electronicsplanet.ch/indservo.htm The better with 'regular' RC parts, is that you don't have to point at the model (SIKU infrared) and you will be able to control the machine more realistic. I look forward to see your creations! /Anders

@TRACTERROR Sounds interesting!!! Do you by any chance have some pics to show? I did a little search for a small differential.... www.kleine-laster.de has some. But at 199? ... www.trino.de is planning SOMETHING about a differential for siku contr. tractors (keep checking his forum) www.modelltruck.de - you can get plenty of help here if you need information on where to get or how to make it yourself. Do a search for 'diff' and you will see some 1:24 trucks with homemade diffs (even with diff locks). /Anders

@Mattias71 Thank you very much! You mean the space inside the tractor or the space for the 'diorama'? Well, for the last part I got in contact with some R/C truckers and that way I found out about the greenhouse. Cool place that keeps getting more and more detailed. A lot of the people down there has their trucks and just drive around. But what's more interesting is the wheelloaders, excavators and mounted cranes on the trucks that all works perfect togehter. Anders Kolpen

Yes, I have a few... Not too good quality, but it shows some of the landscape. As you will see the crane is out of scale. At least I think so... Too bad about the rope hanging down

You mean drawbar hp between my two tractors 9420T & 7920? Sure it would be the 9420T! Imagine 4,5-5kg/10 pounds, tracked vehicle, make spin on no matter what surface. That tractor is incredible strong, compared to the 2WD 7920 tractor. The 7920 also make spin on no matter what surface because of a very strong gearunit. But with it's ~3kg and 2WD it can't pull too much. Next thing to the 7920 will be dual rear wheels as this will make it heavier, have a bigger contact to the ground and I can more or less kill the problem of the differential letting one wheel spin while another is stuck. Thanks for you interest! Anders Kolpen

Yes, it's a crane. The glasshouse is 1000m2 with everything you need as a modeltrucker. Roads, buildings, sand grave?, etc.... in 1/16th scale, for excavators, trucks, forklifts, dumpers and so on. All radio controlled. Really a cool project. In the beginnig of this year me and another member of this group, is going to start the farm part. With tractors and fieldwork. More photos and videos to come in near future! Anders Kolpen Denmark

Thank you all very much. It's nice to see so fine comments! Have a happy new year!

Here is my latest creations for my John Deere 7920 tractor. Lights and an upcoming frontlift! The tractor is an ERTL 1/16th scale JD 7920 Coll Ed. made radio contolled. See more from the beginning at http://www.farmtoysforum.com/forum/index.php?topic=10802.msg181435#msg181435 I removed material from the original lights. Painted them silver inside and fittet some 3mm LED's. The 'bulb'? is made by clear epoxy and finished with a thin coat of lacquer. The rearhitch is made 'one way' working... Now it will not press the implement down and raise the drive wheels. The implements now follows the terrain: A frontlift is under construction: I am building in styrene -plastic. I wanted to build it in brass, but figured that I would start out with styrene and see how it would work. Mostly because it's a lot easier to deal with. Strenght is OK, but a little flexy. Underneath the tractor and over the stabilizer bar I will mount the servo for lifting action. For now the stabilizer is ready... Have a nice day! Anders Kolpen Denmark

This is how it is going to be. I got the idea from a german r/c forum. As the motors are all coupled togehther, the 'inside' motors, when turning, wont need as much power as the outside. Therefore these will automaticly slow down and the outside motors will take more turns. Direct power from 4 gearmotors will make a very strong vehicle Also this will probably be a very cheap setup. You will see more of all this later

The STX 530 will be bought to sit on the shelf for a while, till I get money to start converting to R/C. I have it all figured out. Actually I will have 4 gearboxes/motors. One for each wheel. The differential effect will be electronic. This will for sure be a beast!

Thanks alot! CCF: I'm not too sure on these 'mini' toys. My skills are not to fit all the electronics in there... yet. My interest is more the bigger farm equipments. I still have a lot to do. o Put lights, worklights and beacon light on my 7920 o Work on a 4 or 5 furrow Lemken, Kverneland or KUHN plow, hitchmounted to the 7920 o Finish my FIONA seed drill with stickers etc. o Another future project is a ZUIDBERG frontlift for the 7920 to use a front press when sowing. o This weekend I will order the CASE IH STX 530 wheeled tractor from outbacktoystore.com - and guess what would happend to that toy in the future o Last I would really want to build a V?derstad Rapid 3M or 4M to my 7920 also, but that is just a dream. /Anders

Here is some pictures.... Just shot some pictures, no cool surrondings First is my JD 7920 with JD 567 round baler JD 4255 with corn seeder JD 8320 with disc JD 8320 with LEMKEN Vari Titan 12 furrow plow More to come later /Anders Kolpen

Thanks for all the fine comments! Yes. At the moment I have the JD 2700 Mulch Ripper that raise and lowers. I'm not sure if I would use this for spares or customize it in the future with spring loaded teeths. JD ripper JD disc JD baler JD round baler JD corn seeder, 4 rows Lemken 12 furrow plow (R/C) JD manure spreader Joskin Silo Space Lemken Smaragd In the works is a Lemken, KUHN or Kverneland 4 or 5 furrow plow. Reversible and controlled from transmitter. I just need some square brass 11x11mm to make the frame. /Anders
