Check a spreader setting. Plan the route load.
Enter a measured catch, measured spread width and test distance or time/speed. Keep the setting and material with the result.
The calculator divides measured material by the test area, following MPCA's catch-test example. It uses your chosen measured or target rate for the property areas you enter. Bags are pooled across the route; loose loads use your usable material capacity. Treatment selection stays with the operator, product instructions and site conditions.
Read the catch-test examples and reconcile the load sheet.
Salt spreader measurement guide →How It Works
-
Measure the catch
Follow the equipment maker's collection procedure. Enter net material weight after tare and the measured spread width including where material spreads or bounces. Use measured distance, or time with the corresponding operating speed. Width is not pass spacing or overlap adjustment.
-
Label the record
Record equipment, material, setting, operator, date and speed with its unit. Enter your target from applicable product and site guidance.
-
Compare and repeat
Compare measured output with the entered target. Re-test after adjusting the setting. The tool supplies no automatic dial change.
-
Plan the route
Choose measured or target basis, add named manual property areas, bag weight, usable load capacity and bag price. Print the calibration card and route sheet.

Features & Capabilities
Catch-per-area calculation
Measured-distance and timed-speed tests produce both-unit rates, target catch and signed departure. Zero catch records no discharge and requests a check and re-test.
Manual route worksheet
Named areas use an explicit measured or target basis. Whole bags pool across unrounded route mass; loose loads exclude unused purchased stock. Applied and purchase costs remain separate.
Calibration card and load sheet
Save or share committed inputs and labels. Print both records, or export through the shared ToolGrit PDF panel. Display precision does not establish measurement accuracy.
