What do you do when you might need a little more traction or flotation out of your walk behind mower? Why not add a set of dual wheels? Hey, we've got four wheel drive mowers now, so why not? But how to do this?
The HR215 wheel axels are mounted to the height adjuster arms and the wheels are held in place with a shoulder bolt. The wheels on the HRR series of mowers are held in place with an axel bolt. Hmmmm...Sorry Franken Mower, but I need to borrow your rear axel bolts for a minute....
Take one HR215SM, an extra pair of rear wheels and tires, a pair of axel bolts from the HRR series and you're all set.

The threaded end of the HRR axel bolts screws right into the axels of the HR215 and snug the outside wheel right up to the inner one and the shoulder bottoms out against the axel on the HR215. I'll have to look for a bushing to mate up the outside diameter of the axel bolt to the inside diameter of the the rear HR215 wheel, or use front wheels for the outside duals.

Or maybe I should find another hobby.:dunno: Wonder if there's a cross stitching forum?
