    Yanmar RSA1201 Tiller Gauge Wheel repair

    As it's my first year with my tractor but what I've seen from other farmers is that they are just tilling, tilling, tilling. Then fill up the fields with water, let them sit for a day or less, and then till again. After that, the fields will have rice put in. I just picked up a Yanmar rice...

    Yanmar RSA1201 Tiller Gauge Wheel repair

    I was quite surprised how many don't do their own repairs! But I think that is more of a cultural thing here. Most people bring things back in to be repaired rather than fixing them themselves (whether a small appliance or changing engine oil). I have 4 medium size rice fields I'm using this...

    Yanmar RSA1201 Tiller Gauge Wheel repair

    I have a picture on my phone that I'll try to upload but I am a bit concerned with the NJ-4514 bearing compared to the original bearing. The new bearing has a smaller ball bearing. Curious if they'll hold up. But for now it is working.

    RSA1201 Rotary Tiller Seal and Bearing Replacement - Can I add a zerk?

    Thanks all. I will hold off on adding a zerk for now. I thought I'd test out the 2RS this time around. If it doesn't work out it isn't too challenging to replace the bearing. If I have to go back to an open bearing, I will look more into adding a zerk at that time.

    RSA1201 Rotary Tiller Seal and Bearing Replacement - Can I add a zerk?

    While I was replacing my axle seal on my F15D, the tiller sprung a leak. I replaced seals on both sides, and both sides the seals were in horrible condition. They were shredded. The bearing on the right side was shot, too. I updated the bearing with an 2RS series to help prevent the elements...

    Yanmar RSA1201 Tiller Gauge Wheel repair

    In case others are interested, this appears to be a very similar shaft set up to give you an idea of what the internals should look like. I know mine is different as the C-clip's groove on this one is towards the end. Mine is towards the threads. But I think nearly the rest of it is similar...

    Yanmar RSA1201 Tiller Gauge Wheel repair

    Hi Peter, Various parts non-essential parts, random seals/gaskets, and I like having parts catalogs for the bearing numbers. Machine shops in my area (Kyushu part of Japan) are rather nonexistent. I already threw away my bearing manufacturers list, but I paged through every Japanese bearing...

    Yanmar RSA1201 Tiller Gauge Wheel repair

    I know. Unfortunately, the parts I need diagrams for are missing in that parts manual. I've been visiting Yanmar here in Japan but they always seem hesitant about giving me prints. It's frustrating. I've requested a printed copy of the RSA1201 tiller parts catalog so I'll see if I get lucky...

    Yanmar RSA1201 Tiller Gauge Wheel repair

    I found this video where they call the gauge wheel a tail wheel. Different make but gives me some hope.

    Yanmar RSA1201 Tiller Gauge Wheel repair

    First time poster. I have an F15D Forte with a RSA1201 auto tiller on it. Currently, I'm in the process of changing my rear axle seal. While in the process I thought I'd address my gauge wheel that isn't turning. I started the disassembly process but I'm currently stuck at this point as the...
