A shorten-at-will handle grip on one side of power lawn mowers so that you could get close to fences and other obstacles. It could telescope,  screw-in, or fold. W.P. Twigg, Oak Lawn, Ill.

Garden edging blocks with long stakes precast on one side. Then you wouldn’t have to dig a trench to prevent them from getting kicked around the yard. – Dean Himmelreich, Milwaukee.

Rear-window air deflectors on station wagons to keep out gales, yet allow ventilation throughout the car. The angle could be controllable by a switch on the dashboard. – John King, Ashkum, Ill.

Spray poles triggered at the bottom to operate an insecticide bomb held at the top. They would put you on target for spraying caterpillar tents or wasp nests in trees or under house eaves. – S. Smith, New Augusta, Ind.

High-visibility fertilizers and weed killers so you can see where you have been and not overlap on a lawn. Why not dye the pellets a bright color? S. Johnson, Wesleyville, Pa

A hide-away air conditioner to fit basement windows screened by shrubs. Cool air from a top vent would be ducted to a floor grille in the room above. A. A. Scott, Leonia, N.J.

Screw-in drain plugs for remote outboard tanks. Sloshing a left-over pint of gasoline out of that inch hole at the top of the can is for the birds. – H. Anderson, Cassopolis, Mich.

Children’s roller skates with a clip or other fastener underneath to hold the clamp key. Loose keys, constantly lost, are just a nuisance. – Mrs. E. Ross, San Bernardino, California.

Bumpers with built-in hitches for trailer hauling. Add-on hitches are unsightly and make it hard to get a push in an emergency. F.M. Maguire, Savannah

Designed for a small sports car bucket seat or better still to fit between the two seats, saddled over the hump. – Mrs. Carol G. Donahue, West Andover, Mass.

Although doesn’t look too safe to me!
