Skid Steer Comparison Tool Data Gathering Sheet Skid steer manufacturers produce very detailed marketing brochures which you can review to compare one brand of skid steer against another. The marketing brochures include everything from basic machine measurements, turning radius, engine size, hydraulic flow, attachment capability, operating controls available (hand only, hand and foot, etc.) and whether the cab (ROPS/FOPS) is totally enclosed to allow it to be heated and cooled. Armed with this information, if a user is interested in purchasing or recommending a skid steer they will have most of the information necessary to make an informed decision.

Armed with this information, if a user is interested in purchasing or recommending a skid steer they will have most of the information necessary to make an informed decision. Almost all makes and models of skid steer require the operator to be able to climb into the skid steer from the front of the machine in order to operate it. Therefore, the few questions gathered below are notes about the availability of hand holds, steps, and some general measurements which may affect an individual’s ability to climb into and out of a skid steer, or do maintenance. Also, even with hand holds and steps, skid steers in general are not easy to access and may not be the proper machine for individuals with severe mobility limitations. (Please see the attached pictures for assistance with the questions and where/how to perform the measurements below.)

Skid Steer Data Entry: Skid Steer Data Entry: Skid Steer Manufacturer: ___________Model: ___________ Date: __________ Skid Steer Manufacturer: ___________Model: ___________ Date: __________ 1. Do you enter the skid steer from the front? ____ yes, ___ no 1. Do you enter the skid steer from the front? ____ yes, ___ no (if yes, go to question #3) (if yes, go to question #3) 2. Do you enter the skid steer from the side? ____ yes, ___ no 2. Do you enter the skid steer from the side? ____ yes, ___ no (if yes, go to question # 4) (if yes, go to question # 4) 3. If there is a bucket attached to the skid steer that you must step over to enter the skid steer, how high must you step (top of the bucket)? ___ inches 3. If there is a bucket attached to the skid steer that you must step over to enter the skid steer, how high must you step (top of the bucket)? ___ inches (Note: When recommending a skid steer, be sure you understand “all” the different types of attachments [not just a bucket] that a farmer/rancher might wish to use and thus you may have to step over to enter and exit the operator’s area. If one of these attachments makes entering or exiting the skid steer even more difficult when attached, this may help you decide to use a manual versus an automatic attachment mounting system. With an automatic mounting system, it should be easier to remove [and re-connect] any attachments, and without the attachments it may be easier for the farmer/rancher to enter/exit the operator’s area.)

5. Measure from the ground to here, the bottom of the doorway opening the operator must step across to enter the skid steer operator’s area. 4b. With or without the bucket attached, this would be an example of a second step or platform, on the side or front of the skid steer measured from the ground. 3. Measure from the ground to here, this is the first step if the bucket is attached. 4a. If the bucket was not attached, measure from the ground to here would be the first step.

9. Three sets of hand holds, one inside and two outside the ROPS/FOPS (located on both sides). 8. Doorway height. 7. Maximum doorway width. 6. Minimum doorway width is here, due to inside design of the door.

10. Notice the entrance and exit door latches, describe each.

11. Area to measure for operator’s feet. 11a. Width area for feet, front to back. 11b. Width area for feet, side to side.
