    Default Rotary cutter 3pt pins

    I need to lower the 3pt pins on my 4ft rotary cutter to allow higher lift capability on my BX2200. I was about to drill holes in the 3pt frame when I noticied that the 3 pt frame was connected to the deck frame by 7/8" bolts. Couldn't I just remove the bolts and insert the pins in those holes where the pins would serve as the frame bolt and the hitch pins. There's plenty of room for hookup and raising/lowering without binding and this would make the pins about 3" further down from the point I had planned to drill. My Landpride 42" box blade is/was made that way with the 3pt frame attached to the box blade frame by the hitch pin bolts.

    Try it. Sounds like it should work. If still hesitant, post a picture of what you are talking about. Someone here will surely give you some feedback - good or otherwise.

    Well, I'll give you the otherwise. I don't think you should have to modify a piece of equipment or implement, to get it to do what you want it to. I think someone else had the same problem on the same implement, a couple of months ago.

    Yep, that is what I did except that on the KK brand the holes had to be drilled up in size to accept the pins. It will be better that way and stronger too, why they put them up so high is beyond me. J

    I know 2 people that have done that and I'm planning to do the same (the only reason I haven't is because I haven't had time). I have a King Kutter 5' bush hog and will have to drill those holes out big enough. You're lucky your bolt holes are already the right size!

    We have such a wide variety of tractors.. the vendors are probably just trying to make something that will work for 'most' people. I'm sure they never envisioned the craze of us compact tractor people. Also, keep in mind now that we have tractors that are smaller and stronger than the big iron originals.. for example... the jinma that is sold as a nortrak 254.. is 25 hp.. that is real close to the ford 8n in hp... but look at the size difference.... My NH 1920 is much stronger than the 8n.. yet is very similar in size as well.
    There is a vast difference in widths as well. My yanmar 1700 is cat1, can run a brush cutter.. but can't use the normal 26" cat 1 drawbar due to tire clearance in the rear.. has to use an 18" or so. Many have made devices to adjust the 3pt lift pin placement up or down ( or even turning them in or out ).
    For size.. tha asian market must really challange the american impliment makers...

    Thanks for the posts guys - I'll be lowering the pins this weekend and will repost if I have any problems.

    Solo, your right that I don't have to modify the pins to get it to work because I've used it in its current condition (the cutter is an older model brand unknown that had been reconditioned by an older gentelman that loves to fix up stuff that I picked up for $200 in perfect working condition with a recently reconditioned deck). Lowering the pins is a want of mine to get more clearance at full lift and so that the hookups match my other equipment (all with pins turned in). I enjoy riding the tractor - not beating and kicking the heck out of it and the implements to use them.

    Also, I want to change the gear oil in the gear box just so I know what's in there and how old it is. Was going to use 80W-90 gear oil. Is that OK and how much does a typical gear box need ? I'd guess no more than a quart but again, that is a guess.

    80W-90 is what most of them take. It shouldn't take more than a quart, they don't require much.

    I start mine off with a bottle of STP oil treatment, then top it off with 80-90W gear oil. I have seen a mixture like this used on heavy industrial gearboxes for years with absolutely no gearbox problems.

    I figure anything as slick as STP has to reduce friction and wear on open gears like this. I have also used it in differentials and standard transmissions with good success.
