Thiswill give you a little wiggle room with the chicken wire.  4.  Install a block for you axel and add a nut witha washer to the outside so that the axle doesn’t sag. 5.  Stack enough washers on the axel to ensure thewheel doesn’t rub the frame.6.  On the sides, measure the distance of where youwant the door to land and eliminate one upright support on either side.  7.  Consider buying 2 or 4 extra 2x3’s in order torun them diagonally to increase the lateral support. This would be in lieu ofthe vertical supports or in addition to them. If I did another one, I would adda the cross brace from the top where the door lands to the bottom where thewheel is located.  If you are using metalon the side, this is not necessary.  8.  Consider metal on the sides.  This will increase the rigidity of the frame.9.  This may be hard to visualize and if so email meand I’ll figure out another way to explain this…  On the next tractor I build, I will have theoutside walls on the outside of the front and rea wall.  This will enable you to use the existingvertical supports to hold you waterer. I didn’t do this and I needed to installblocks to accept the waterer.   If you can think of some suggestions, please email me so wecan share them with everyone.  Everytractor I built is very close to this design but I’m always looking to makethem better.  Thank you for visiting this page.   God bless you!Kevin
