OutdoorKing Repair Forum Forums General Discussion Forum Show and Tell Deutscher H660 26" walk behind w/B&S Intek 10.5hp - needs TLC,now what?

[quote=N1KK0]

Anyway noticed it's cut height is a low of 22mm.

Made me wonder what the H660 is rates and and oddly it claims 10mm! Which I'm not seeing in practice at all - will go measure on the floor of the garage but well off this - no idea why as the tyres are pumped up all to spec (20psi) etc.



PS. Been meaning to ask this - when using the H660, I found the Low Speed terribly slow, whereas the Fast was a tad nippy, especially round obstacles (lots of Citrus trees) - is 'riding' the clutch(having in gear but applying varying levels of squeeze to the handle so the belt is pushed in/out a certain amount) in this style of gearbox an absolute no-no or vaguely acceptable?

I'd have thought it ok as the gears are engaged constantly, only the belt's tightness is altered.[/quote]

Hi Nick ,

With the cutting height being out ,I always check the plate that holds the spindle bearings hasn't been bolted on the wrong side, thus
raising the blades if the plate is bolted on top instead of being bolted under the deck.

It's always a lot quicker to compare your mower with another to see if something is installed wrong or bent ,I've had mowers where the
blade plate is bent upward and you straighten the plate and it lowers the blades a good half inch, blades also can be bent and need to
be flattened.

I contacted Deutscher days ago about the stepped blades and to measure the step but they never replied.

With first being too slow and second being too fast and slipping the V belt ,the more the belt slips the quicker the wear ,I wouldn't
say it's been designed for constant slipping but I've had ride on mowers where the gear speed is just controlled by how
much the V belt slips.

I see the Deutscher mower lists it's speed in gear at 2500 rpm ,so I would try second gear at a lower rpm and see if the speed is right
or speed up the rpm in first ,if the speed still isn't correct I'd put some lower profile tyres on to slow down second gear.

They also don't recommend cutting on a slope greater than 10 degrees to the horizontal.

On normal flat terrain I would think these mowers would cut well between 1800 rpm and 2500 rpm.

Deutscher also recommend to use a low throttle settings when engaging the ground drive, especially in high gears.
Reduce speed on slopes and in sharp turns to prevent overturning or loss of control
Do not mow excessively steep slopes.

If the blade at the front is a lot lower than the blade at the back then the front wheels need lifting or rear wheel need lowering
if you cant adjust the deck but you need to check the blade plate and blades aren't bent.

Cheers
Max.
