Interesting. When I looked at my owners manual for my 1025R I did see in the service section where a person is supposed to remove the one rear tire in order to remove the suction screen. That didn't seem like much fun, but it is what it is I guess. I think I saw a link to a YouTube video where a guy shows you how to remove (or clean) the suction screen without removing the rear tire. I haven't watched the video yet, so can't say if is accurate. You know more about working on a 1025R, because you owned one. I am a new1025R owner.
Sounds like you have done good amount of PTO, ground engaging, FEL work. You have worked your tractors like tractors. I plan on using my machine mostly for mowing. (I do have a FEL that I can use for moving snow.) I guess using a 1025R for mowing seems like a bit of overkill. I mow our church yard that about four acres with a few trees, but is most open. It also has slight slopes and a few areas that are a little tricky (steeper rises near the edges - which I may have to weed eat now instead of mow for safety sake.) I have looked at the JD X700 series machines, but they just don't seem to be sturdy enough (to me) as far as the tractor frame is concerned especially where the engine is located on the frame. The frame metal is like 1/8" of inch thick at that location. I think the sturdier frame of the 1 series tractors is the better way to go. Plus I have wished I had 4 wheel drive for several years; just for use is a couple of areas in the yard where our two wheel drive tractor tears up the yard from spinning (if I fail to use the differential lock). I have been using the church's JD 430 lawn and garden tractor to mow with for several years. It is/was a solidly built machine, but it is showings its age. It is 26 years old now. It needs some TLC that I can't personally can't give it - I don't have the know how. Plus many parts are not readily available now. It would probably take about $2,000+ to get rebuilt parts (hydrostatic pump plus other parts) and labor to get the 430 in better working order. IT has been worked on a couple of times in the past four or five years, but it is still having issues. Having a new(er) machine will hopefully make things easier on me for mowing, plus I can move snow (and other stuff) now if I need to.
