52'' hydro wb, ztr mower mod

[demhustler]

small mod on 52'' ztr hydro walkbehind mower - just one of new pumps - bigger than two stock : )
(pumps - 21cc hustler SZ vs 10cc stock)

 

[demhustler]

first stage - to replace pumps with with minimal changes to hydraulic syst. and make it run, - cooling, reconfiguration of hydraulics system, controlls, etc - later

 

[demhustler]

couldn't resist to mod controls, fiberglass and CAD systems widely used : ))) (Cardboard Added Design)

 

[demhustler]

stage one - completed, tests show - hydro works good, as expected; controls need to be changed

 

[demhustler]

now work can be continued on hydraulics reconfiguration, adding cooling, redesign of controls, sulky needs be able to wiggle it's tale a bit, add seat : )) , etc
any ideas - welcome
:smile:

how 'bout those...?
: ))))

25'' instead of 20. stock fenders had to go...
about 13 mph (stock -10) but it beets 15 mph hustler super-z on 50 yard one way, u-turn and back - with or without turf damage.
this frontmount baby turns like on rails, like compass, while midmount have to slow down very early, or slides and skids through the turn
