720 tractor moves like a tractor half its size...
delivers full-sized workpower

We build our big one around total versatility.  To plow, disc, cultivate ... handle front end loaders, rear mounted tillers and center mounted mowers. Stuff with plenty of size, to handle big lawn and garden work in fast time.

It has the frame beef and component weight, the power and versatility to be a fast working back-up unit for landscapers, municipalities and airports; the primary power for clean up work on construction and commercial contract jobs.

So, if there's a less than 20 H.P. job to do around your place, our 720 qualifies in a lot of ways. Versatile ways.

EASY-READER . . . what would you like to know -- oil temp. or pressure, hours on the job, throttle setting . . . amps, choke position, electric PTO clutch on/off position? It's all there on a non-glare surface.
CUSHIONED RIDE . . . the adjustable seat is molded of soft-riding material . . . with a good-sized backrest. You sit between two high-rise fenders that lap over the wheels and shield you from dust and dirt.

CATEGORY 0 THREE POINT HITCH . . . standard equipment. Has both float and locked positions on the lift arms. Set it to give depth controlled implements free run of the land: lock it to add down pressure wherever extra "weight" is needed.

HYDROSTATIC DRIVE . . . works through three range transmission. Matches engine rpm's and horsepower to ground speed to deliver ideal implement performance on just about any job--from tilling sod to blowing away snow.  No clutching or braking--one lever handles all of the action instant forward, instant reverse. Charge pump delivers full hydrostatic and hydraulic power- no starving individual functions. Internal fluid lines, no high pressure oil leaks.
