I have a 1982 Bolens QT 17 Model 1666 with a Kohler KT 17 Series II engine. I dropped off of a small hill and the mower deck bottomed out with the front left deck support hitting and cracking the block. Have not snatched it yet but, engine is still able to run, so may be salvageable. I have purchased a Kohler Magnum M 18 (shown below). It looks to be fairly close in size, and length on the crankshaft. Can I hopefully repower my machine with this without having to jump through a lot of hoops? Would appreciate some knowledgeable answers.
