Nice mowers. I like to see older mowers being saved from the grim scrapper. Thanks for sharing the story and pictures. Hope you enjoy the forum.
Part of my problem was that when the hydrostatic transaxle on my #1 Honda H1011 went out, I discovered that a replacement unit was between $850 and $900 plus shipping, depending upon the dealer. Even a new standard five speed **** transaxle was listed for over $400. So, I felt lucky to find a very nice one on eBay for $90 plus shipping.
Neither could the hydrostatic unit be repaired. There are no spares offered by Honda, nor is there any information available in their manual to even disassemble the unit. Basically, it became an inexpensive doorstop. It's still sitting there on the floor of my shop, looking rather sad. LOL.
The big job for me was ordering the parts necessary for the changeover. Fortunately, the parts themselves are actually quite reasonably priced. There were a lot of them however, as it was necessary to add a clutch pedal and linkage and also change the brake linkage to the standard shift design. The shift linkage had to be changed as well and it was necessary to add additional mounting tabs for the rear of the transaxle since the frame is different there.
The thought of buying a new John Deere, Poulan or Cub Cadet with another hydrostatic transaxle was not something I would care to do. The manufacturers consider the hydrostatic units to be "sealed units" that are "not user serviceable". Every new mower that I looked at was hydrostatically driven and I wasn't ready to spend big money for a unit that was not repairable, even though they are quite reliable, at least when new. That meant that buying a new mower was a non-started for me, even if I had cared to spend the money, which I didn't.
One other clinker was the fact that the engine on the change-over mower had developed a terrible oil leak. That was initially a daunting task because it required the removal of the engine and taking off the bottom casting which is the oil pan. Fortunately, I have a good mechanical background and the manual was quite good in that area. A $10 base gasket and about 4 hours work and all was well so the engine could be put back in.
Happy Trails to my new lawn mowing friends.
