You should be able to buy straight blades with no off set and no up lift bend. . I assume yours use the standard 1 1/2" pin hole. You only have to consider width and length. You might consider sharpening both sides and valving the hydraulics so you can reverse direction as the cutting situation dictates.

I checked the blades last night and found them to be hardened steel. No way I can bend those as is. I would have to anneal, flatten, reharden and then temper them. I'll see if I can live with the blades as is and if not either get new flat ones or go through the annealing process.

I can reverse the motor direction by simply swapping the hydraulic hose connections. It would be nice to be able to have two sets of edges on the blades, especially when there are so many hidden rocks here.

Have any more specs on the hydraulic unit? Looking to build one for myself. Wandering as why the need to add a gear system on it and not find a pump to run a high gpm with 540 rpm’s?

I already had a quality (Italian) pump that I bought a few years ago at an auction and I wanted to use it. If I didn't have that pump I would have just bought one of the regular PTO pumps that puts out 20gpm. That would have been much easier. I even considered doing that instead of making the speed increaser but I enjoyed the challenge. Turned out well too. In your case I would just go with the typical PTO pump and motor to suit. There are a few threads on the topic and they even list the pump and matching motor specs for this sort of the thing.

More news! I got the hydraulic tilt function installed and it works great. It's a little jerky when it is first lifted from the horizontal position so I will add adjustable flow control valves to the 3rd function. I will get some pics later and post them. Uploading a video is a little complicated but I will see if I can get that done too.

For my uses, this feature is awesome!!

Be careful reversing direction. The Lane Shark only uses a regular nut on the shaft and reversal will turn it loose. OTOH my Brush Monster cutter uses a castle nut and is designed to be run in either direction.

Looks like a great job.

I don't know your terrain, but be careful of lifting all that weight on any kind of slope. The roadway maintenance rigs around here all have counterweights

hillbilly, neat set up. I also have concern for cutting with it high in throwing trash on the tractor and windshield for your safety. If you have a rear remote on your tractor you can run hoses from it to operate the hyd cyl with great control over the 3rd function valve, well the one I have run.

The Lane Shark now has a newer design blade carrier, blades and retention nuts. I just retrofitted mine and have not tested it yet, but it has obviously heavier blades and fool-proof blade retention with cotter keys and ribbed bolts that you can seriously tighten, unlike the original design. Concur about caution lifting weight (off center especially) on the FEL. Mine is a heavier tractor than the 6060 and the Lane Shark has never shown any tipsie effects for me though it is always a caution to watch out for. I have a 2700 lb rear-mounted articulated arm cutter and cannot cut much with it on the lower side of the tractor fully extended 17ft. That will (and has!) raised one of the rear wheels off the ground and scared me big time. Of course it would only go so far because the cutter soon contacted the ground and removed the leveraged weight hanging out there. Easily recovered once I gathered my wits but it is absolutely a concern whenever weight is lifted off center on any tractor.

OBTW, neighbor next to my farm with a 25hp or maybe 28hp John Deere lifted what looked like a not-too-big load of stone in his FEL and rolled the tractor. Was not even much of a slope ! It happens. Roll bar saved his butt and he came away without injury. He said it went over as if in slow motion. Apparently he failed to react and lower the bucket.

I don't see myself reversing direction for now or maybe forever, depending on how this works out. So far I have only run a few tests to see how things are working and what needs to be changed. This setup also has the cstle nut with cotter pin. I wanted to take the blade carrier off and got the castle nut off, using an impact wrench, but could not get the blade carrier off. I will need a puller to get that done. So for now I will just use it as is and after some more use I will know if I want to change the blades to flat / double sided or if this is OK for my needs.

As far as terrain goes, I would not be running this on any terrain with no cross slope but I appreciate the warning and have also had experiences with tractor roll with elevated loads. The first time was when I got my first tractor many years ago, luckily I reacted correctly and dropped the loader to the ground and the load was only a couple of feet off the ground. Tractors are not the best design for lifting heavy loads high, if there is any cross slope because of the floating front axle.

hillbilly, neat set up. I also have concern for cutting with it high in throwing trash on the tractor and windshield for your safety. If you have a rear remote on your tractor you can run hoses from it to operate the hyd cyl with great control over the 3rd function valve, well the one I have run.

So far I have not had that issue but I haven't had enough seat time yet to determine if the cab will get hit with debris or not. I have watched a bunch of videos for the Lane Shark, it's clone and the Limb Ninja and don't see them having that issue. However they all use flat blades and therefore do not create up draft.

This is my first tractor with a 3rd function and I much prefer the diverter I installed on my old tractor. With the diverter I could feather the flow to the implement with this it is either on or off, with full flow. I installed a couple of flow control valves on the 3rd function but they don't seem to make much, if any difference. Weird since they are one way, fully adjustable and rated for up to 15gpm. At first I couldn't tell which settings were more flow and which were less, so I adjusted to both extremes and soon found out which was less. Fully closed you can hear the relief valve cut in as soon as the 3rd function is engaged. There are about 10 full turns from 0 to full flow and even at around 1/8th of the first turn it doesn't seem to reduce the cylinder speed much, if at all but I can hear the valve restricting the flow and I can feel the valve get hot. I'm going to call the vender and talk to him about it.

Do the rear remote act the same way? I have 2 and was has a float.

You can buy the remotes either way, with detents or not, etc. What I would love to have (and never will afford) is an option on the larger Deere tractors where you have a selectable remote or set of them that can be set to as to type: flow control, detent into float and no detent. Truly the universal what-not. Would be so handy. Wish list.

About thrown debris: I was very concerned about debris being thrown by my first FEL mounted skid-steer style very heavy cutter, then my rear mounted articulated boom arm cutter and now with the Lane Shark. To my relief NONE of them turned out to be a threat and I have an open station, not cab, tractor. There are some POSSIBLE more dangerous positions with the boom arm because it has so much flexibility but you'd really have to work at it to get into trouble even there. I'm more concerned about blades coming loose and flying for 50 feet or more.

I guess with Hillbilly having the homemade rig he probably has a unique different set of possible debris throwing so you just have to test and try it out. No other way really tells you. Your added hydraulic angular adjustment probably adds some potential debris paths (??) Good luck with that great project !

what do you plan to cut with this?
