        Today was my day to try and come up with a fix for one of my biggest headaches.  Radiator plugging up with small seeds.  We bush hog in August to let the does raise their fawns up a bit so weed seeds at that time are a big problem.  Not sure why but I took off the bracket and air filter that sits in front of the radiator and really liked the look of that wide open radiator with nothing in front of it.  I can see ways to use a filter to prevent seeds from plugging the radiator much more easily. I would like to move the air filter/intake behind the radiator over the engine on the left side and think with a little modification can make it work.  Does anyone see a problem with this? 

        Thanks

          I have a 2000 Jinma 254 and I don't see anything wrong with moving the air filter as long as it fits fine. What ever you do DON'T put any part of it outside the hood.

           

          I have been mowing my land and anything that is outside the engine cover could have been ripped off. In fact, many things did get ripped off as I mowed down trees and very tall brush and briers. They ripped me up almost as much as the tractor. I have a lot of maintenance to do now. I was surprised the mower was able to chop up 2″ diameter trees.

            Thanks Carl, I agree anything outside is likely to be pulled off, including the operator, or parts of him/her at least.   I did notice that the drain(?) on the filter housing which I think is for water/condensation accumulation would be right over the injector area.  I have never seen any liquid coming out of this yet.  I have also looked for a smaller filter/housing.  Anyone have a suggestion there.

            Thanks

              Hello DogDoc, I use a modified standard 20″ by 20″ in home air filter(the inexpensive blue or green fiber filters) to keep the seeds and chaf out of my radiator. It works well for this. The way I do it is that I remove the paper frame of the filter and insert the filter element between the metal grating that sits in front of the radiator and the radiator. This set-up does need to be cleaned from time to time depending on how much chaf and seeds are being stopped before they make it into the radiator. I have found that it is much easier to change/clean the filter than to clean the radiator. I put a hose clamp with a thumbscrew on the engine intake filter Hose since my Farmpro 2430's hose blocks the removal of the metal grating. That way I can clean the filter in about 2 min without tools. My tractor runs at about 140F-180F under normal working load so when I see it go north of 180F I stop and clean the filter. The tractor always goes back to the normal range after this. Hope this helps. I also posted on this topic earlier if you're interested.

                Hmm, that furnace filter is a good idea but I think I may try fastening one to the removable screen with nylon ties. Sometimes I have to come to the shop and blow the radiator fins out two or three times to cut a two acre field.

                  That is what I did last year, tie wraped filter to the screen and it worked well.  You could knock the seeds off the pull out screen/filter combo pretty well.  The air intake  filter and its bracket were a pain to work around for me, so I am looking to move that contraption behind the radiator to give clear access to the front of radiator.  I am thinking of pop rivets and washers to attach the filter material to the screen already there.  It is a work in progress, and as usual am probably making a simple problem to hard.

                    If you move the filter to the rear of the radiator that will exposed the fins to all the trash your trying to keep out.

                      Moved the air intake, a piece of scrap strap metal and 5/16 all thread to make the bracket which is sandwiched between the diesel filter bracket and the block.  Neoprene pvc connector ( 1 1/2 x 1 1/2) attaches to the air intake.  Leaves the front of the radiator wide open, and now fabricating a filter system for those pesky seeds.
