Hi, My Hustler super Z mini's honda GXV670 is blown after 700 hours. I'm looking to swap the engine. The Honda's shaft size was 1.125 (diameter) x 3.75 (length), and I would ideally like to keep the original pulley and PTO. I'm having a hard time finding a used riding mower with a 1.125 shaft...

Hi all, This is my first Ferris walk behind, (what a BEAST)!. Excited to get it ready for mowing season. Picked it up recently, not running, but overall it looks to be in very good shape. After checking the oil, and subsequently draining it and watching water come out, I knew I was in for a...

I have 14 hp Kawasaki FC420V on a 36 inch walk behind mower. It usually starts on the first pull, but if it doesn't then on the second pull the engine snatches the pull handle back from my hand which is not comfortable. It will then usually start on the third or fourth pull. Any suggestions...

My cousin brought a MTD snow blower to me. He said he got it with no compression. The engine has the number 270-WJ. It looks like it has seen very little use. Oil looks almost new. I have never messed with a MTD engine. Not sure if there are any problems that are common to these? I was going to...
