My dream replacement machine for residential yard maint. would be a smaller version of the Bobcat toolcat with the following list of features and specs:

1000 lbs net when configured for mowing.

44" wide, 96" long (no attachment), 78" max Height.

24 x 9.5 x 12 aprox tire and wheel size all around.

2 seats like a UTV.

1000 lbs payload in the cargo bed with 250lb operator.

Four-bar roll cage with FOPS on top and seatblets for two.

Dumping cargo bed.

4wd, but with turf-friendly hydrostatic drive to all wheels.

4-wheel steer or optional rear-wheel steer to go with the front-mount mower deck.

Built-in loader boom with 800 lbs Rated operating, 2500 lbs tip angle. 1500 lbs hydraulic stall. True self-leveling configuratin.

25-30 HP liquid-cooled Diesel engine.

All attachments on loader boom out front like mini-skidsteers.

Compatibility with mini-skidster attachments. Quad-compatibility or available adapters big plus: Toro Dingo, Bobcat, PowerTrac.

Loader can lift all attachments for storage on a shelving unit.
(interlock to prevent mowers, snowblowers from being run while lifted too high).

Removable cab / panels with heater.

Standard 2" receiver hitch in rear for towing.

8-10" ground clearance.

Slight amount of 4-wheel ind. suspension travel for smooth ride and better traction.


Available Attachments

48" wide bucket.

54" finish mower deck with floating suspension and gauge wheels.

Optional materials-collection for mower deck. Materials deposited in cargo bed with additional soft-sided cover/top.

54" brush deck.

48" snowblower.

72" snow blade with power angling.

Winch.

Keep dreaming. /forums/images/graemlins/grin.gif

You hit all the right items, though. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

Nice list but I think to get the strength-to-weight ratio you're looking for the frame/chassis/body/engine block would have to be built from extruded pure unobtanium! /forums/images/graemlins/grin.gif

I work in the steel industry and have never heard of this unobtanium you speak of. Could you tell me more about it? What are some of it's properties?

I am only familiar with it on RC shock shafts. They last much longer than hardened shafts.

I am not so much worried about the frame. Its easy to build things light and stiff using large cross sections. For example, large tubing with thin walls or space frame type of design.

I am imagining a mostly aluminum frame and plastic panels.



The three design challenges I see are:

1. Loader arm design. On the front of the machine there will not be much space. It will need to be a clever deign to not intrude into the operator space too far. Also, it can't pivot out too far as it rises because balance is already an issue. Finally, the loader arm needs to be light to maintain balance and keep the net lift capacity high. Maybe aluminum boom? Maybe aluminum bucket?


2. Balance / Ballasting.

To get a high capacity in a small, light machine, will require carefull attention to balance. Adding permanent weight reduces the flexibility. Adding ballast every time you want ot use the loader will be a PIA. The answer is to get the front wheels close to the loader and a lot of the other weight back on the machine. Think rear-engine like a skid steer. This of course makes the cargo bed design height an issue if it sits over the engine.

3. Cost
Lots of hydraulics. Cost would be pretty much everything you would have on a larger machine, but less frame and smaller tires.
