Spring Grove MN | It is a great update to the tractor. Like others said - 25K-27K for the conversion with painting. Dad had an 8640 done. There is no comparison on before and after. The series II conversion rebalanced the tractor and gave it a frame to hold the motor instead of it being a structural piece of the front end. The flex of the engine from being part of the structure caused a lot of head and cylinder leaks. I will say that you should not shift the hi/low under load. Ours couldn't take that. Just let the engine lug some instead of shifting down and the clutch packs will hold up. The old 619 had to be 1800RPM+ when the mulch tiller hit the ground or you would be stepping in the clutch or killing the motor. With the 855, you could drop the tiller to full depth at 1000RPM and it would just walk with it as you rolled on the RPMs. Dad has a 5010 and 5020 Knize conversions as well. I feel Jon did his homework and made some big improvements with his conversions. You should not abuse the tractors though. The tractors can't take the HP + adding weight for continued everyday ABUSE without you risking something breaking. If you use common sense, they will hold up well. | |
