I believe a good part of the reason that that style of walk behind isn't sold over hear is because most people well to be blunt is there just to darn lazy. Im not trying to start any arguments but its just the truth. I enjoy working with my walk behinds. It seems to me that there just as usable as a riding tractor and in some situations more so. I would love to use one of those big jap tractors. Seem like real work horses. I can see advantages and dis advantages of riders vs walkers. There's no perfect answer. If I were gona build one ( ive considered it many times) id start with an existing transaxle like a sears, wheel horse, bolens, etc. It would be easier than trying to make a complete drive train and figure out how you want to make a reverse. And that way you have multiple gears forward. Just my opinion.
True, i use both.
It might be worth looking at the transaxle from a Bolens 1250. If you mounted the engine to the trany you would still have speed control from the hydro. You would just have to make a linkage to control the speed. Good Luck, Rick
Good idea, hydro gives indefinite ground speed control.
All the tube frame Bolens.
Simplicity Sovereign and Landlord 3 speed trannys with the axle diff and variable speed.
Sears Suburbans 3 speed with the high/low tranny (which i always wanted to try building into walk behind)
massey ferguson 12, 14 and 16.
Cub Cadet 102 and others.
And a range of other good tractors, all of which attachments can be found for and half the tractor is already built.
The gear box has always been the most difficult to build and most expensive, the walk behind tractor revolves around the gear box.
I thought about hydro using hydro Haldex variable speed motors per wheel and Haldex single stage engine driven pump, mount the engine/pump on top of a well built hydro reservoir. The Air Track drillers at work are like this, every thing is hinged off the hydro reservoir tank and carry frame.
